Making Uncrustables at home with this DIY method is super convenient because you can make them in bulk and keep a stash frozen for when you need them. Here, you’ll learn how to make them and my tips for sealing the edges well so the filling doesn’t ooze out.


How to Make Uncrustables
- Make a PB&J
Keep most of the filling in the middle when you make the classic sandwich.

- Seal and remove the crust
Push down from the sides, like using a cookie cutter, and once you’ve cut through the bread, press the middle sealer down and hold it in place for 15 to 30 seconds to seal the edges. Cutting it first, then sealing, ensures a tight crimp and helps prevent the filling from leaking. Holding it down will seal it tightly and prevent the filling from leaking. After that, pull the crusts away from the sealer.

- Store, Pack for School, or Freeze
Refrigerate them for up to 1 week, pack one or two inside a lunch box along with healthy lunch sides, or freeze them.
How to Freeze Homemade Uncrustables
Make a big batch and freeze them inside individual zip bags for quick grab-and-go lunches. Or, freeze them flat on a baking sheet, and once frozen, transfer them to a gallon zip bag. While they can last frozen for 3 months, I find that after a month, the bread starts to feel a little dry and freezer burn begins to show.

Laura’s School Lunch Packing Tips
A sandwich crimper makes the job faster, seals your homemade Uncrustables much tighter, and gives them that classic sealed edge. You can use a large round cookie cutter to cut them, use a glass to seal them tight, and press the edges together with a fork.
Soft sandwich bread seals the easiest. Fresh bread is less likely to crack around the edges, giving you a better seal that keeps the filling inside.
Absolutely! Make sure to check out my gluten-free uncrustables recipe to see the results of making them with the most popular gluten-free breads.
Absolutely! Try almond butter, a nut-free peanut butter alternative, cookie butter, cream cheese and jam, or your family’s favorite nut or seed butter with fruit preserves. Just avoid overfilling the sandwich so the edges seal completely.
Easy Homemade Uncrustables (Freezeable!)

Watch How It’s Made:
Ingredients
- 8 slices sandwich bread, your favorite
- ¼ cup peanut butter, smooth or chunky
- ¼ cup jelly or preserves, your favorite
Instructions
Make the sandwiches:
- Spread the peanut butter on half of the bread slices, keeping most of it in the center, especially the jelly. Make as many as needed.
Seal & remove the crusts:
- Push down from the sides, like using a cookie cutter, and once you've cut through the bread, press the middle sealer down and hold it in place for 15 to 30 seconds to seal the edges. Cutting it first, then sealing, ensures a tight crimp and helps prevent the filling from leaking. Holding it down will seal it tightly and prevent the filling from leaking. After that, pull the crusts away from the sealer.
Freeze for later:
- If making a lot, place them on a parchment-lined baking sheet and freeze. Once frozen, transfer them into a large zip bag and keep them frozen. Or, place each uncrustable inside a sandwich size zip bag and freeze individually.
Pack for lunch:
- Pack the frozen uncrustable inside the main compartment of a lunch box. Add any sides, like fruit and veggies, in separate compartments or containers. If the uncrustable is inside a zip bag, just add it directly inside the lunch bag.












Tricia says
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??
MOMables says
Tricia,
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.
Suzanne says
will this work with nutella?
MOMables says
It sure could!
Shari says
Cream cheese and jelly might also be an option instead of a nut butter.
MOMables says
great idea!
Kat says
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!
Bethany says
I love this! I was just wondering how long these would stay good in the freezer?
MOMables says
About 30 days in a freezer bag. Anything longer the bread tends to dry.
Tiffany says
What about using this idea for the “grilled cheese” uncrustables? Maybe they could be popped in toaster or toaster oven?
Laura says
hmmmm might have to test that….
Valerie Testi says
Anyone try grilled cheese uncrustables? I think it could work?
MOMables - Laura says
They could absolutely work! Make sure you use the crimper so the cheese is sealed inside. Enjoy!
Mary Ellen says
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.
Laura says
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! :)
feelingalittlelunchy says
I spread peanutbutter on both sides of the bread to keep the jelly from glooping out the top…and I eat them frozen, too. Mmmmmm….
Vicky says
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?
Laura says
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
Linda says
Or Tahini ! It’s made from sesame seeds and very popular.
Mary Wilson says
Is the flash freezing to keep the sandwiches from sticking together in the bag?
MOMables-Laura says
Yes! Freezing them on a baking sheet first will prevent them from sticking together.
Pat says
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!
