Instant Pot Ground Beef Meatballs in marinara sauce with fresh herbs

Meatballs are tasty. Stuffed meatballs are even tastier. Stuffed meatballs made in an Instant Pot and paired with a homemade marinara sauce? The tastiest!

Forget frozen meatballs made in the Instant Pot; Homemade meatballs are healthier and tastier! By making meatballs from scratch, you can control the ingredients you add and even have a little fun. That’s what we did by stuffing our meatballs with melty mozzarella cheese! We love how the Instant Pot locks in the flavor and cooks them quickly.

How to Make Instant Pot Meatballs and Marinara Sauce

Our mozzarella stuffed meatballs are made with a mixture of lean ground beef, breadcrumbs, grated parmesan cheese, egg, oregano, garlic powder and black pepper. After mixing this all together in a large bowl, it’s time to create our meatballs and stuff them with cheese!

We use three light mozzarella string cheese sticks to stuff about 15 meatballs. Cut each cheese stick into five pieces. Scoop a golf ball-size piece of the ground beef mixture and place a piece of the mozzarella in the middle. Wrap the meat around the cheese to form a ball. Repeat this process until you have used all of the meat and cheese. You should end up with about 15 meatballs total. 

Next, it’s time to make the marinara sauce and get cooking! Your Instant Pot is back to make your healthy cooking faster and easier. Set your Instant Pot to SAUTE and once it gets hot, add in olive oil. Add in chopped onions and minced garlic, then sauté for a two to three minutes. Add the rest of the sauce ingredients to the Instant Pot, which includes a can of salt-free diced tomatoes, a can of salt-free tomato sauce, tomato paste, oregano, dried basil, black pepper and a pinch of red pepper flakes. Continue cooking the sauce for five minutes. 

Place the mozzarella stuffed meatballs into the Instant Pot and submerge them in the marinara sauce. Cover the Instant Pot with the lid and adjust it to SEAL. Set it to MANUAL for seven minutes. Once it’s done cooking, let it naturally release for five minutes and then quick release.
