My two biggest battles when it comes to getting dinner on the table every night are time and picky eaters. These Instant Pot meatball sandwiches solve both of those problems!

Since I cook them in my Instant Pot, the pot does most of the work so I can do something else while dinner cooks. Plus, since I only use one pot, clean up is a breeze too.

Even better, I don’t have to listen to groans when my kids sit down to dinner. Meatballs, drowning in sauce, piled into a bun so they can eat with their hands? It’s pretty much everything my kids love in a meal!

Fast, kid-friendly, and delicious. It’s no wonder this is one of our favorite busy weeknight dinners.

How to Make Instant Pot Meatball Sandwiches

Like almost all of my dinner recipes, these meatball sandwiches super simple! In just a few simple steps, you’ll have a dinner on the table that the whole family will be excited about.

Step 1 – Brown the Meatballs

You can use homemade or frozen meatballs. I’ll confess to using frozen meatballs when I’m really in a hurry, but I really love the flavor of homemade!

Whether you use frozen or homemade meatballs though, you’ll want to brown them. So, heat up some oil in your Instant Pot on the saute setting and brown the meatballs.

Step 2 – Saute the Vegetables

Once the meatballs are browned on all sides, add the chopped peppers, onions and garlic. Cook them until they are translucent.

Step 3 – Add Sauce and Set Timer

Now you just need to add the sauce to the pot.

Place the lid on the pot, select “meat/stew” and set the timer.

For fresh meatballs, set the timer for 10 minutes. For precooked meatballs, set the timer for 2 minutes.

When the timer goes off, let the pressure release naturally. Then, spoon the meatballs into buns to serve.
