These meatballs and gravy come together in the Instant Pot in under 30 minutes, with frozen meatballs simmered in a savory brown gravy made with garlic-herb butter and a splash of pepperoncini. A quick, low-effort dinner that still tastes like you put real work into it. it.
Set Instant Pot to saute (I use a 6 quart Instant Pot). Melt butter, add in onions and saute until they begin to soften. Add in garlic. Saute 1 minute.
Pour in beef broth and scrape bottom of pot to deglaze. Get any stuck bits off the bottom. Add in salt and pepper and stir.
Pour in meatballs, cover with gravy. Add pepperoncinis and juice. Cover with lid and set to lock. Make sure vent is closed. Set to manual high pressure for 6 minutes.
After cooking time is up, use quick release method (open valve to release steam and pressure). Remove lid and stir.
