Healthy Homemade Uncrustables – Easy + More Fiber!

My kids are always excited when their sandwiches come with no crust. Or if they do have a regular sandwich, half the time they’ll just leave the crust.

Instead of getting frustrated with it, I picked up a handy sandwich cutter & sealer to make them extra happy when they opened up their lunchbox and found a crustless sandwich waiting for them, along with lots of other lunch favorites.

If you’ve ever looked at store-bought uncrustables (like Smuckers uncrustables), the ingredient list on the product package is long and includes hydrogenated vegetable oils & lots of sugar.

Buying that isn’t a norm and something I’d keep on hand to serve daily, so instead I make it at home. And now you can too!

Why you’ll love this homemade uncrustable sandwiches recipe

Better ingredients – By using natural peanut butter with added ground flax, along with homemade low-sugar chia jam, we are instantly adding more dietary fiber (and less sugar) to make these homemade crustless sandwiches a more healthy option than what you’d buy at the grocery store. Instead of having hydrogenated oils, we’re adding healthy fats from flaxseed and chia seeds.

Easy to prep – I love batch-prepping a ton of these at a time and then freezing them. Get set up assembly style and go from one slice of bread to the next adding the thin layer of peanut butter and then jam, then sealing with the second piece of bread. You’ll find freeze instructions a bit further down this page.

Customizable – You can make way more than peanut butter and jelly here. First, if there’s a peanut allergy, almond butter or sunflower seed butter are fantastic options. But we also like to make ham or turkey and cheese crustless sandwiches. The sandwich cutter comes with an extra cutter that helps you get the perfect size for deli meats and cheese, so that your sandwich seals perfectly every time.

How to make crustless sandwiches

Step 1: Make your own homemade uncrustables with these easy steps. Mix 1 tbsp ground flaxseed with ¼ cup natural peanut butter and set aside chia jam.

Step 2: Lay 4 slices of whole grain bread on a flat surface. To the slices of bread add 1 tbsp of peanut butter/flax mixture and 2 tsp of chia jam right in the center of the bread. Add the second slice on top and use your crustless sandwich-making tools to remove the crust and seal them up. This makes 4 crustless sandwiches, but feel free to make more!

To add to lunchboxes or enjoy for a quick lunch or snack, remove as many sandwiches as you need and allow to defrost at room temperature.

Substitutions, optional variations & dietary adjustments

Below you’ll find a list of substitutions that will work well in this easy homemade uncrustables recipe. 

If you try something different out, please leave a comment below letting us all know how it turned out!

Whole wheat bread – Any type of bread will work here, just ensure it’s softer so that the edges can be pressed together to seal.

Natural peanut butter – Look for a no sugar peanut butter with just peanut and salt as the ingredients. You can make this peanut free by using almond butter or nut free with sunflower seed butter.

Ground flaxseed – An optional addition that boosts fiber. Feel free to swap in hemp hearts here.

Chia jam – Any type of jam will work here. The addition of chia seeds adds healthy fats and fiber. Use your favorite strawberry spread or make a grape jelly sandwich.

Sandwich sealer – If you don’t have a sandwich sealer, try this. Use a cookie cutter to cut out the shape of the bread, then use a fork to press the edges closed.
