This super simple Uncrustables recipe will impress your favorite PB&J fans and save you a whole lot of money at the grocery store!

Ode to Uncrustables and Other Convenience Foods

Before having kids I didn’t understand why people reached for convenience foods. I straight up slammed people for buying overpriced and over processed foods.

As much as I hate to admit this, I’ve had a long love affair with convenience foods after the kids were born. If you’re a regular reader, you probably already know this from reading a couple of my past posts about convenience foods here and also here. When life gets busy, convenience foods are the best. I don’t think I would have survived taking care of my mom during her cancer treatments if I had to cook 3 meals from scratch daily.

I’m currently off the convenience food bandwagon and it feels good. I cut out processed foods from my diet in January of 2020 and it feels so good.

Basically, I’m including this little bit in this post because I don’t want anyone to think I’m mom shaming anyone who buys real Uncrustables. No shame. I’ve bought them and I’m sure I’ll buy them again. I just love knowing how to make them at home for a fraction of the price!

How to Make Homemade Uncrustables

When it comes to easy school lunch ideas, PB&J is clearly the winner. You really can’t go wrong, but you can elevate it by making your own Uncrustables.

It’s super simple. All you need is a Mason jar or any other wide mouth jar or glass cup. A cookie cutter will work in a pinch, but I find that it cuts the bread instead of sealing it like the jar does.

Check out this video to see how easy it is.

The key to making homemade Uncrustables with a mason jar is to really press down to seal. Once you get the hang of it, you will be churning them out much quicker than I did in this video.

Once you have them made, throw them in the freezer until you pack them for lunch.

How long does it take to make DIY Uncrustables with a mason jar?

I’m going to let you in on a little secret: I made 10 of these in 15 minutes. I spent less than $5 on all of the ingredients too!

What kind of bread works best for homemade Uncrustables?

I’m a huge fan of bakery bread and homemade sourdough (get my recipe here).  I love that it’s fresh and usually has less preservatives. As much as I love it, I’ve found that soft processed bread works the best.

White bread works best, but I’m all about wheat bread these days. I’m loving the Nature’s Own bread. This is not a sponsored post, I just wanted to let you know the brand I’ve been using.

How do you store homemade uncrustables?

Wrap them up and freeze them.

I’ve been a fan of using these recyclable and compostable paper sandwich bags. As an avid environmentalist and compost business owner, I’m in love. These bags are awesome and freeze really well.

I bought mine at Target, but you can order similar ones here on Amazon.

Make sure to use them in 2 weeks or less if you use compostable bags. They don’t seal well in the freezer. Standard ziplock bags or glass freezing containers work better of long term storage.
