How to Make Salad in a Jar That Lasts a Week–a Video Debut and FAQ

I‘m not much in the mood to cook this week. I usually feel that way after marathon cooking sessions connected with holidays or parties, even though I love doing it. Just as well. I have something else to share.

I recently put up a new video on You Tube entitled “How to Make Salad in a Jar That Lasts a Week”. This is no great Hollywood production but I hope it will inspire you to give this idea a try if you’ve been curious.

This also seems like a good time to answer questions about making Salad in a Jar in a way that’s easier to read than sifting through the entire comment section. If you still have unanswered questions, leave them in the comments here and I’ll get back to you ASAP.

Frequently Asked Questions about Salad in a Jar

I’ll start with the NUMBER ONE, TOP QUESTION!

1. Can I include other vegetables along with the lettuce?

Yes, but the length of time you can keep the lettuce-filled jars will most likely be shorter (much shorter in some instances) depending on which vegetables you add and how fresh they are in the beginning. Personally, I never add anything to the lettuce for 3 reasons:

  • It takes longer to prepare the jars. I don’t want to spend more than 20 minutes–MAX– on a job that loses its novelty after awhile. Don’t misunderstand. 20 minutes of trouble is well worth the benefit– kinda like doing push-ups. But this is a lifestyle for me so it has be sustainable.
  • I want my salads to last at least a week or longer.
  • I never know what kind of salad I’ll be in the mood for from one day to the next so a simple jar of lettuce gives me a clean slate.

Reader Rick did an experiment adding various veggies to his jars of lettuce.  You can read about it here.

2.  I’ve heard rinsing the lettuce in lemon juice or vinegar will help it stay fresh longer, so maybe I don’t really need this machine.

After a reader suggested this, I did a side-by-side experiment rinsing lettuce with diluted lemon juice compared to vacuum-packed lettuce. The lemon-juice-rinsed and cut lettuce was beginning to turn brown after 3 days. No comparison!

3.  Any suggestions for other ways to use a vacuum-pack machine?

There are too many to count but these are MY current favorites. See comments on the original Salad in a Jar post for other ideas.

  • Use jars for rice, flour, oatmeal, granola and other dry pantry items. It’s also good for homemade stir-fry sauce, barbecue sauce or salad dressing stored in the fridge.
  • Use the (way too expensive) bags for cheese, leftovers, and meat. (Can you tell I am not compensated in any way by FoodSaver?)

4.  Are the flat lids used to seal the jars reusable?

Yes, until they get bent or they rust. I still use some of the ones I started out with 7 years ago.

5. Do I need an attachment for each jar and where do I buy one?

No. The attachment fits over the opening with a flat lid between the top of the jar and the attachment. Once sealed, the attachment is pulled off. See video.

Large mouth jar attachments are available online.  I’ve never seen them in a store but sightings have been reported.

6.  Which vacuum-pack machine should I buy?

I only know about FoodSavers so I can’t speak about other brands. Look for a machine that has a port for the attachment. I talk about that in the video. You don’t need all the bells and whistles for this project but the really cheap ones don’t have a port, so beware.

7.  I prefer to tear lettuce with my hands or cut it with a plastic knife because it helps keep the edges from browning. Why is that unnecessary with this method? Vacuum-packing removes the oxygen that causes the lettuce to brown. I use a sharp knife so I can chop it fast and in fairly small pieces. Hands and plastic knives are way too slow for me. Remember?!  20 minutes. MAX. That’s all the time I allow.

8. Can I preserve other types of greens in the same way?

I’ve experimented with spinach and spring mix. Neither lasted more than 3-4 days. They’re just too fragile. Although some say it works for them. I can’t recommend it. I’m a hearts-of-Romaine girl.

9. How often do you eat salad in a jar? 

It’s what I take to work for lunch every day– along with a very small serving of something that’s hot i.e. soup or leftovers, just to keep things interesting.  

10. Do you get tired of lettuce?

Honestly, yes. I weary of preparing the jars so I try to do it on the weekends when I’m not tired or rushed like I am at 6 AM getting ready for work. If I get sick of eating salads, I take a break but I’m usually back to them in a day or two because I feel more energetic and my clothes fit better. When I get bored, I switch up the toppings and dressing.

11. I already have a lot of old Mason jars but they don’t have a wide mouth. Can I still use them?

Yes, but the wide-mouth jars are much easier to fill, empty, seal and wash. I HIGHLY recommend them.

12. A vacuum-pack machine can be pretty pricey. Any suggestions?

Places you might check include Tuesday Morning, Ross, eBay, warehouse stores, Walmart, Target and online. Or just ask around.  Many people have one sitting in their cabinets that they quit using after they ran out of the original bags that came with the machine.

13. One last reminder. Wash your lettuce thoroughly and keep refrigerated at all times for safety’s sake.


Many thanks to my friend, Caleb Hastings, who shot and edited the video.  I think he did a great job considering what he had to work with.

Here is a sampling of what others are saying about their experience with Salad in a Jar

(We’re talking about vacuum-packed lettuce here– not to be confused with the many versions of a layered salad with dressing and various veggies added to the jar but not vacuum-packed.)

Hello from Finland! And thank you for your great blog! I have made my yogurt already several years, but got so good new advise from you! : )
I also vacuum my salad in a jar. One question – quite often I find that a part of the sealed salad is frozen! My fridge is +4Celsius. The jar is not touching the inner walls of the fridge. Could it be that vacumed items react to temperature “more actively” i.e. get more easily frozen????


Paula June 8, 2016 at 8:28 pm

Interesting question, Tiina. I don’t know the answer but I would certainly be moving my salad to the other side of the fridge ASAP. 🙂 paula


Tiina June 13, 2016 at 4:25 am

Thanks Paula! I was wondering could one effect be that I have been lazy in drying the salad..? If the salad is slightly wet in some parts, could that cause freezing when vacuumed? Chemistry is not my strong poing at all…….. : ) Tiina


Lisa January 5, 2016 at 7:07 pm

I got a good deal on my Foodsaver at Kohls. I had 30% off coupon, Kohls cash, and a rebate. All worked together for good. Looking forward to making the salad.


Paula January 6, 2016 at 1:13 pm

Wow girl! You know how to work a bargain. Hope you enjoy the convenience of vacuum-packing salad.


Mary January 23, 2015 at 1:01 pm

I meant filled with ice water or cold water…. 😉 not a bowl of just ice.


Mary January 23, 2015 at 12:59 pm

Oops… Did I forget to mention I tear (or cut if I am in a hurry) my lettuce(s) into my salad spinner (filled with ice or cold water) and that is how I basically wash it. I drain and spin then add any extras if I wish, such as radish slices, etc. This makes my salad ready to go once it is put into the paper towel lined bowl. When I want a salad, I just grab a handful and throw it into a bowl, add extras such as tomato or olives, dress and eat. Sometimes I just eat it as is, unless I want something fancy. My salad keeps about 2 weeks like this and I have salad whenever I want. Threw some (dry, undressed) in a plastic container the other day and had fresh salad for lunch at the senior center last week while everyone else had mashed potatoes, greasy gravy, etc. Mine tasted better too….with apple slices for my dessert. I added sharp white cheddar cheese with black pepper (a wonderful cheese) to my salad for my protein and fat and had Italian dressing (fat free) which I carried on the side. My lunch was so much better than what was being served and it was really zero work because the salad was already made in the fridge.

Any way that one can have salad ready to go is a good way to have healthier meals with little to no work.


Mary January 23, 2015 at 11:44 am

I make it in a large bowl and it lasts 2 weeks. The trick ti my method is to simply line the bowl with paper towels, with extra hanging out of each side. I double line it going two ways, basically forming an X, and using two paper towels in each direction. I place the washed and spun till fairly dry lettuces in the center, fold the extra toweling “arms” in the put the plastic lid on the plastic bowl. I do not add certain veg, such as peppers because they will not hold up but I do add sliced radishes, carrot, etc. because they will last as long. I add tomatoes, onion, peppers, etc. just before serving…if I want them. The real trick is the fact that the paper toweling will wick off not only moisture but also lettuce rust so the lettuces stay crips and green. Works for heads of lettuce too. The dry
(Folded into a pad) paper towel at the base of the clean washed head of lettuce, then bagged in a clean bag and air somewhat removed, will wick the rust off the lettuce. This allows a single person to use a head of lettuce without having to trash most of it.

Paula, great video. Love the concept. Great picnic idea as well. Thanks for sharing!


Rachael February 28, 2013 at 7:43 pm

I am so glad you did this video, enjoyed it and love your site. Keep up the great work! Now I’m going to go make myself some salads in a jar!


Karen January 9, 2013 at 10:42 am

Golly, I just can’t see the purpose behind all this fuss. I grow lettuce in my garden, and in summer when it is too hot, I buy it at the Farmer’s Market. I rinse all the leaves in cool water, then spin dry and put into a zip lock bag with a paper towel. All my lettuce lasts 2 weeks in my 37° fridge. Sometimes, a few of the romaine leaves may have some brown on the white stem part of the lettuce, I just cut it off. I alsom grow Mizuma, arugula, Tatsoi, Bak Choi, and other greens. They all last well.


Paula January 9, 2013 at 11:36 am

Oh, how I envy you. A garden to grow your own lettuce (too many trees here) and a good Farmer’s Market. And look at all those varieties you have to choose from. Wow! My situation is different. Vacuum-packed salad in a jar works for me because the lettuce is CHOPPED and ready to eat. Since I live in suburbia, work full-time and like to carry my lunch, it is super convenient to grab a jar on my way out the door. Even if I had a garden and washed the greens ahead of time, I’m pretty sure I would not take the time to tear and cut lettuce at 6:00 in the morning. I guess there are a few other people like me, so this technique helps them as well.

Thanks so much for writing though, and enjoy your wonderful garden.


Virginia August 29, 2012 at 10:32 am

I am a deaf person who is really interested in this idea. So when I saw that your video is supposedly captioned, I was quite excited to watch it.

Sigh…another victim of YouTube’s claims to have an “instant captioning” program that takes care of your accessibility concerns. Sorry, but so much. If you turn on the captioning and watch your video, you will see that this captioning program is loaded with errors that make watching your video basically incomprehensible. That’s because it is based on utilizing voice recognition software – it “listens” to the soundtrack and attempts to translate it into written mode. As you can see, it does a poor job of it.

Fortunately you do have enough written content that I can get the gist of what is in the video, and of course there are other sites with information as well. However, you may want to keep this in mind for future videos. I recommend that you upload an actual typed up transcript to YouTube when you upload your video – then YouTube will insert the transcript into your video utilizing the proper wording.

Thank you.


Paula August 30, 2012 at 5:09 am

Hi Virginia,
So nice to hear from you. I have never given a thought to the whole YouTube captioning thing. I wrote the post years before the video so I know you don’t have to have the video to figure it out. Nevertheless, it is worth looking in to. Thank-you.


Trudy August 4, 2012 at 7:14 am

Salad Dressing suggestion: I start with Good Seasons Italian salad dressing mix (the little envelopes) but use balsamic vinegar and olive oil and change the ratio to make it healthier. I use recommended amount of vinegar, double the amount of water, and still fill to line on the jar with oil (which is less than originally called for). The balsamic is such a strong flavor that it doesn’t taste watered down. For taking to work I use those little glass jars that had jelly samples in them. Sometimes they come in holiday fruit baskets. I’ve also been known to swipe them off room service trays in hotels (when set out for trash of course!). Enjoy your blog! looking for a foodsaver vacuum at yard sales now!


Paula August 4, 2012 at 4:58 pm

Thanks for the salad dressing idea, Trudy. Definitely going to try it.


Leann April 5, 2012 at 3:20 pm

I find many uses for mason jars and my foodsaver vacuum attachment – I freeze shreaded cheese, cooked ground beef (great for chili, spaghetti, sloppy joes, tacos without having to cook it every meal), all dry goods stored in pantry – I also found some 2 quart wide mouths that are wonderful for that. I also use mason jars for most of my leftover dinner storage in the fridge. the pint size wide mouth makes a great way to reheat (remove lid) and serve for lunches.


Nancy in NW PA March 15, 2012 at 1:07 pm

The UPS guy just brought my mason jar sealing attachment and I am so happy. I’d gotten my foodsaver several years ago from my son and daughter-in-law and really didn’t use it much. I would dig it out and use it occasionally but never wanted to give counter space to it. Got some romaine (the BEST stuff) and followed your instructions. It works fine and even better – your video on using a handheld device was just what I needed. I already have one and it takes up even less space. All I needed was the jar sealer. Now I’m back to eating salads more often. Thanks.


Paula March 16, 2012 at 6:16 am

Hi Nancy,
Your story sounds much like mine. I would never have imagined eating a big salad nearly every day if you told me that 10 years ago. Like you, my vacuum sealer rarely saw the light of day after I went through the bags that came with the machine. Thanks so much for writing.


Brenda @ Meal Planning Magic December 31, 2011 at 10:36 am

This is a great video–thanks so much! I want to start doing this in the New Year and dust off my Foodsaver and put it back into use! Do you know if the wide-mouth vacuum sealer will work on small mouth jars too? I have a combo of both styles and want to make sure I get the right jar mouth sealer. Thanks so much for all your great ideas!


Paula December 31, 2011 at 10:54 am

Hi Brenda, Happy New Year! Your attachment must match the size of the mouth of the jar. Therefore, if you have regular-mouth jars, your attachment must be the smaller one. Wide-mouth jars require the wide-mouth attachment. I recommend the wide-mouth jar. The seal easier and and much easier to fill and empty.


Julie December 9, 2011 at 2:30 pm

Excellent follow-up to your original post! I recently linked to your original post and added my own thoughts on my blog, including a much less expensive alternative to the FoodSaver for vacuum sealing:


Jessy @ Farm Flavor December 8, 2011 at 3:08 pm

Great video, and thanks for linking to our Salad in a Jar post!


Jenny December 6, 2011 at 9:10 pm

Your video looks great, and you had a really nice “stage” presence in front of the camera!


Paula December 7, 2011 at 9:16 pm

Great to hear from you Jenny. My applesauce turned out great although I was a little heavy handed with the mulling spices. Either left it too long or used too much but not really a problem as we are eating it like crazy. I found it is delicious mixed up with my homemade yogurt.


Jen December 6, 2011 at 12:43 pm

Love the video! You seem very relaxed and natural 🙂


Vicky Duecker December 5, 2011 at 8:00 pm

Hi! I found wide mouth pint jars at the grocery store here in town (HEB in Fredericksburg, Tx.) and bought a case along with one head of Romain lettuce. Dear sweet hubby(DSH) did the food saver routine after I stuffed the jars! One head did 4 jars for me to use this week. I took jar #1 today and was totally impressed because it was so fresh tasting, even after cutting and stuffing in the jar! Hope this helps others who need the smaller version of jars! I will DEFINITELY pass this info along to others! The test is days down the road this week! Love your site and info!
Vicky D

ps…saw the hand held machine on amazon and contemplated getting it for my daughter but not sure if she would use it or not…gotta confer with her before spending the money! BTY…Amazon has the pint size bags for the food saver machine that I had never seen before! Yes, I ordered me some…DSH said “cheap enuff!” so, I ordered three sets of 28 bags! Amazon & I are great friends! (you should see my book case of cookbooks…..) 🙂 Hugs and God Bless!


Paula December 5, 2011 at 9:04 pm

Yep, Amazon is flat dangerous for me. Seems like you and me, both, might have a thing for cookbooks. Hope you like the salad. Paula


Vicky Duecker December 3, 2011 at 8:15 pm

Question I have is this……if you don’t fill the quart jars full, like half way, and seal them with the food saver machine, does the lettuce still stay as long as you say it does for full jars. I like a big salad too, but sometimes time does not allow me to eat as big a salad as I like to at work! Thanks! Vicky D


Paula December 3, 2011 at 8:18 pm

Vicky, Yes. The lettuce will stay just as long. I have opened jars, poured some out and resealed the half that was left. No problem. Paula


Megan's Cookin' December 3, 2011 at 7:52 pm

Loved the video! I sooo want a foodsaver too. I was going to ask for one for Christmas but I wanted a new biker more. I’ll have to keep an eye peeled for one at a yard sale or thrift store!


Meghan December 1, 2011 at 9:09 pm

I found your original article posted on Pinterest a few months ago and just got to try this last week. The salad still looks fresh in my fridge! Thanks!!

I just wanted to add that although I had read about this months ago, I only just got to try this last week because I do not have a foodsaver and I did not have the money to purchase one. While walking through Target last week, though, I found a little gadget next to the foodsavers that is a hand held foodsaver. It’s like having the hose portion of a foodsaver, they even make special bags that work with it. Best of all it was only about $18! I bought that as soon as I saw it. I purchased the regular and wide mouth sealers from amazon. So if you really want to try this method and don’t have a foodsaver look for the handheld version! It works great!


Paula December 3, 2011 at 8:21 pm

Meghan, I went out an bought one on your recommendation. You are right! I wrote about it on my Facebook page. Now I am giving it away (don’t need three FoodSavers). Thank you very, very much for figuring this out. Saves space too compared to the big ones. Not quite as versatile but many people won’t care about that. Paula


Pam D. from MI December 1, 2011 at 5:53 pm

Thanks so much for doing the video. I’m a newcomer to your blog and enjoy it very much.


Becky December 1, 2011 at 12:15 pm

Great video, Paula! I have been thinking of getting a Foodsaver for some time, but I am afraid it would languish in the pantry. Do you use yours routinely for other foods?


Paula December 1, 2011 at 12:26 pm

I do use it but more for salads than anything else. See #3 in the list of FAQ on this post for some ideas. The bags FoodSaver sells to use with their machine are ridiculously expensive so that decreases my desire to use the bags. Anytime I can use a jar is better. Thanks for writing.


`Suzanne December 1, 2011 at 11:45 am

Love this video, another great video that inspires me to get busy. Paula that is a lot of lettuce for your lunch, now I know what is keeping so thin. So glad I found you over a year ago, I enjoy your blog and the comments back and forth. BTW my friend made your rolls for our Thanksgiving and they were fantastic :).


Paula December 1, 2011 at 12:13 pm

Yes, Suzanne, it is a lot of lettuce. I love to eat–what can I say? But when I finish with my fairly simple but tasty salad, I know I have eaten–unlike eating 2 pieces of pizza, for example, that goes down fast and barely fills me up and has twice the calories.

Glad to hear the rolls were good!


The Café Sucré Farine December 1, 2011 at 6:28 am

Fabulous job Paula! So professional and easy to follow! I’m going to be looking for a good buy on a Food Saver now that I’ve seen this wonderful technique! Thanks!


Betty @ scrambled hen fruit November 30, 2011 at 11:40 pm

Love your video! (looking forward to the yogurt one too) I got my Food Saver at a thrift shop- it was nearly new. I have the attachment for a small mouth jar- I’ll have to see if I can find the wide mouth now! 🙂


Der November 30, 2011 at 5:25 pm

That was great, Paula!!!! Watching you in the kitchen is even more inspiring than looking at your beautiful pictures. When are you going to do a yogurt video?


Paula November 30, 2011 at 6:58 pm

Actually, I’ve already done a video on making yogurt but it’s not ready yet. Thanks for your encouragement.


Lorraine November 30, 2011 at 4:53 pm

Excellent video tutorial, Paula! I love watching and listening to you 🙂
