DIY Frozen Uncrustables

Make the popular freezer isle sandwich at home with your favorite whole-grain bread and nut butter. This is also fantastic when your child attends a nut-free school by making it with a nut-free butter alternative. 

DIY Frozen UncrustablesLet’s make a popular not-so-healthy kid favorite healthy, shall we?

Uncrustables are always on my kid’s shopping list. I’ve heard ” MOM… can we get these, pleeeeeeaaaase?”  too many times to count.

What if I told you could make a week’s worth of these lunchtime  favorites in no time at all?

The best part is you can use you kiddo’s favorite PB & J or if needed, allergy friendly peanut butter.

Here’s how you do it:

I’ll be showing you how to make these DIY Frozen Uncrustables with a sandwich sealer, or a large glass with a THICK edge. The sandwich sealer I used can be purchased almost anywhere. I have also seen similar sandwich sealers at our local grocery store.

How to make an Uncrustable

How to make DIY Frozen Uncrustables

DIY Uncrustables

1. Start buy placing your favorite peanut butter and jelly filling in the middle of one piece of bread. Make sure to leave some room on the outer edges, where the sandwich will seal.

2. Place the second piece of bread on top, and use sandwich sealer or glass to seal sandwich, by pressing and holding firmly for 30 seconds.

3. Make sure to remove crusts while the sandwich is still in the press or glass.






Freeze Uncrustables4. Flash freeze sandwiches in the freezer for about 2 hours.





Place DIY Uncrustables in  bags5. After the 2 hours, you can now place sandwiches in individual sandwich bags or all in one big freezer bag for storage. Homemade Uncrustables can be frozen for up to a month.

When you are ready to use, simply pack in your child’s lunch box frozen, and it will thaw in-time for lunch, or microwave for 15-20 seconds if you need to serve them immediately.

    I do not worry about sealing my sandwiches. They freeze fine and are great when thawed. I’ve done them all: grilled cheese, meats with/without cheese, PB, Tuna with added chopped celery and pickle (pickle patted dry) is great. Tuna takes a little longer to thaw but heck they’re already made! Just hold back the lettuce, tomato, onion and pickle slices for meat and tuna till just before serving.

    Two questions……first, could you just freeze the entire sammie?? (without sealing and cutting crusts off) and, second, if you did ham and cheese would mayo freeze okay, or should that be left off too??

      you can definitely freeze the whole thing (with crusts). You can also freeze ham and cheese (with mayo) sandwiches. Vegetables do not freeze well in sandwiches.

    We just made a couple of these tonight using a cheap Toaster Pastry press that I had bought from Williams-Sonoma.
    My husband likes his PB&J toasted so I did one with toasted bread and one without toasting. That didn’t turn out so well since toasted bread doesn’t like to be molded. What did work was making the pockets as directed, checking for leaks or holes and then toasting.
    I am so excited to make a full batch for lunches. Thanks for the inspiration!

    What about using this idea for the “grilled cheese” uncrustables? Maybe they could be popped in toaster or toaster oven?

    Have you ever tried this with gluten free bread(we use Udi’s)? I’m wondering if it would “stick” together as easily as regular bread would.

      I have and it does. you may have to “crimp” the edges a bit more… but it works great. Remember to save the crusts for the frugal french toast sticks! :)

    Hi Corey
    I love these, what a simple yet brilliant idea! Unfortunately my son’s not allowed pb at school because of other children’s allergies and I’ve never seen your alternatives in the UK. Does this work with ‘drier’ fillings like cheese and ham?

      Hi Vicky!
      You can freeze any sandwich containing deli meats and cheese. It is a great time saver! lettuce and tomatoes do not freeze well. Yes, you can use this same technique to seal the bread but make sure the ham and cheese are “tucked” inside the bread. You can also make your own sunflower butter (sunflowers are not nuts). -Laura

    Awesome! My daughter loves sun butter sandwiches since she’s got a peanut allergy. I cannot wait to try these out. You rock, Chef Corey!
