Step 1

For the meatballs: In a small bowl combine bread crumbs and buttermilk, stir and let sit for 5 minutes or until the breadcrumbs are a moist.

Step 2

In a large mixing bowl combine the ground beef, ground pork, bread crumb mixture, egg, parmesan, onion powder, garlic powder, Italian seasoning, parsley, salt and pepper. Using your hands, gently mix the ingredients, being careful not to overwork it. Shape meat mixture into balls, approximately 2½ inches in size.

Step 3

Turn Instant Pot on SAUTE mode. Once hot add olive oil. When oil is shiny and hot, add half of the meatballs. Quickly brown the meatballs on all sides, rotating every 2 minutes or so. Remove meatballs and place on a paper towel lined plate. Repeat with remaining meatballs.

Step 4

Pour half of the sauce into the bottom of the Instant Pot. Add meatballs, then pour remaining sauce over top.

Step 5

Secure lid and select MANUAL (high pressure) mode for 7 minutes. Once the meatballs are fully cooked, let the pressure come down naturally. This can take about 10 minutes. When the pressure valve drops, remove the lid and serve with spaghetti or on subs!
