Homemade Uncrustables (DIY Frozen PB&J)

Jump to Recipe

These homemade uncrustables are easy to make and freeze before your next camping trip. Your kids will love them, and you’ll love the money you save…

Smuckers Uncrustables® are delicious and wonderfully convenient. We’ve packed them on many-a-camping trips and rarely came back home with any.

They’re a go-to for kids and adults alike. However, their price isn’t nearly as convenient as the little grab-n-go sandwiches themselves. Unless, of course, you make your own!

You can easily make DIY frozen PB&J sandwiches if you buy a little kitchen gadget called a sandwich cutter and sealer. It’s small and very lightweight, so you can add it to your RV kitchen.

Or, better yet, you can use the tool to make homemade uncrustables before your camping trip. Then you just transfer the sandwiches from your home freezer to your RV, and you’re ready to go!

Some Quick Tips

We’ll jump straight to the recipe card after this, but we want to share a few really quick tips. The most important being whether you buy square or round sandwich sealers.

  • Make sure you don’t include any crust when using the sandwich cutter. Otherwise, it won’t seal properly.
  • The square sandwich cutter and sealer is ideal because it leaves the least amount of waste. However, you must ensure the sandwich cutter fits within the crust of the bread you’re using. So, don’t buy small bread, and be warned that pieces near the ends of the loaves might not work.
  • The round sandwich cutter and sealer is perfect for those picky eaters that refuse to eat any sandwich that doesn’t look exactly like Smuckers Uncrustables®. You end up with a bit more bread waste, but less sandwich waste overall since your kiddo will actually eat it.
  • You don’t have to waste the leftover bread crust at all! You can use it in a delicious French toast casserole that you can also make in advance. (We’ll be posting a recipe soon!)

We recommend serving them with this fruit salad, which you can also make in advance!

Can You Put Uncrustables in the Fridge?

According to Smuckers, Uncrustables® should not be kept in the fridge longer than 24 hours. And the same is true for homemade versions of Uncrustables®. While you can defrost your DIY frozen PB&J in the fridge, they will dry out if you leave them too long.

Easily make AFFORDABLE homemade uncrustables with a nifty kitchen gadget and the following tips.


  • sandwich bread

  • peanut butter

  • jelly


  • Spread a thin layer of peanut butter on BOTH slices of bread. This creates a “jelly barrier” to keep the bread from getting soggy.
  • Place about 1 Tbsp of jelly in the center of one slice. Don’t overfill, or the sandwich will burst when you crimp it. Place the other, peanut-buttered slice on top of the jelly slice.
  • Center the sandwich cutter and press it into the sandwich. Be sure not to include any crust, as it will not seal properly*. Then push the sandwich sealer through the cutter to seal the edges.
  • To freeze, place all premade sandwiches on a cookie sheet and freeze for 2 hours. Then transfer to reusable freezer bags (either individually or in bulk) and return them to the freezer.
  • To thaw, pop them in the microwave for 20-25 seconds. Or, remove from the freezer a couple of hours before eating. If you put them in your hiking pack in the morning, they’ll be ready by lunch!



  • *The square sandwich cutter and sealer leaves less waste, but some bread slices are too small to use it. You need to make sure the cutter fits between the crust, otherwise it won’t seal properly.
  • You can use the leftover crust to make French toast casserole- Yum!
