Can You Freeze Sandwiches for School Lunches?

I had a very productive day on Saturday making frozen school lunch sandwiches and thought I would share the process with you. I posted a few pics and videos on Instagram and got quite a few messages that said, “You can freeze sandwiches??” The short answer is YES.

Much like you can freeze prepared burritos, you can freeze sandwiches as well (well most sandwiches). And they are great to have on hand because they make healthy packed lunches a breeze!

Rules for Making Frozen School Lunch Sandwiches

Think about it. You can freeze bread, cheese, cooked meats and veggies all by themselves – so why not assembled in a sandwich? There are a few ingredients that should be avoided though … much like raw veggies would not freeze well by themselves, they would not be a good fit frozen on sandwiches either.

GREAT in frozen sandwiches:


  • Cheese (any type such as goat cheese, havarti, cheddar, mozzarella, etc., grating it first could improve the texture)
  • Cooked meat (such as leftover chicken, sliced steak, deli meat, bacon, etc.)
  • Cooked onions (grilled, sautéed, or even better, caramelized)
  • Cooked, sliced veggies (roasted, grilled or sautéed: zucchini, yellow squash, tomatoes, mushrooms, eggplant, bell peppers, etc.)
  • Sliced, raw tomatoes are okay if you’re going to grill the sandwich before freezing


  • Pesto (my favorite!)
  • Peanut butter or nut butter (great paired with jam or honey for a homemade “Uncrustable“)
  • Hummus


NOT good in frozen sandwiches (but could be added just before serving):

  • Lettuce
  • Sliced cucumbers or other raw vegetables
  • Raw onions
  • Pickles

How to Freeze Sandwiches

Putting the sandwiches away in the freezer is the easy part, but there are a couple of ways to do it.

  1. You can portion out the sandwiches, wrap each one in foil, and throw them in one big freezer-safe bag together (don’t forget to mark the contents and date)!
  2. Or you can spread the prepared sandwiches out on a baking sheet, freeze them, and then transfer them to a freezer-safe bag together after they are frozen.

How to Defrost Sandwiches

I personally pull out any frozen school lunch items the night before (whether it’s a sandwich, soup, muffin, waffles, or biscuit) and let it defrost slowly in the fridge overnight. My girls took the sandwiches I made and froze on Saturday to school yesterday (pictured below) and both told me come lunchtime they tasted great!

One even said she couldn’t tell at all it had been frozen. She said it tasted just like a regular sandwich I made that morning. Although she actually said it was even “better than a regular sandwich” because it’s hard to beat a yummy grilled panini with tasty ingredients. Even if it’s served cold. Yay!

I also made a big batch of tomato bisque that I froze in individual portions on Saturday as well and paired it with the sandwich to make for a quick and easy school lunch. All I had to do was boil and add the whole-grain noodles to the soup and cut up the fruit, which took no time at all!

Frozen Sandwich Examples: Paninis

I made two different types of sandwiches in our panini grill. They were both delicious and freeze well!

  • Panini 1:
    • Goat cheese
    • Spinach/basil pesto (recipe from my first cookbook)
    • Roasted bell peppers (they had free pepper roasting at our farmers’ market!)
  • Panini 2:
    • Havarti cheese (one of my daughters is not a fan of goat cheese so these are for her)
    • Spinach/basil pesto
    • Roasted bell pepper

I’m going to have to do my best to not use up all my frozen sandwiches too quickly—they are so nice to have on hand. If you have any tips for freezing sandwiches please share with us in the comments below!

  1. I am nervous about the sandwiches getting soggy. Do you unwrap them completely? Surely the bread would get stale? Do you leave them wrapped in foil but no baggy? Leave them in foil and baggy? I’ve tried the frozen breakfast burritos before and always had an unpleasant, soggy tortilla. What gives?

    1. Hi Catherine. If you’ve wrapped them in foil first, then let them sit in the foil, still wrapped, in the fridge overnight and they will be defrosted by lunch time the next day. I would say, stay away from putting them in a bag as that will create moisture which will cause soggy bread. Hope this helps. – Nicole

  2. So if the sandwich needs heated up, you do that before freezing? Like if I had a grilled cheese, I would grill it then freeze. I wouldn’t just put the butter on each slice of bread and a piece of cheese in the middle , freeze it, then grill it after I take it out of the freezer, correct?

  3. I do this every night for my preschoolers peanut butter and honey sandwiches. I second putting nut butter on both sides. Works like charm! I make his at night and freeze. Then pull it straight out of the freezer to his lunch box the next morning. It’s completely thawed by lunchtime!

  4. When you make nut butter sandwiches, put nut butter on both sides of the bread and jelly or honey in the middle. This keeps the sandwich from getting soggy while it dethaws!

    1. That sounds like a great suggestion even if making a fresh sandwich that will still not be enjoyed until 4-5 hours later! I love tips and tricks!
