Frozen meatball casserole with a creamy sauce turns out great on stove or in Instant Pot
Casserole with frozen meatballs makes this one pot dinner easy to cook. Pair with egg noodles for a complete meal.
I love Instant Pot meatball casserole but you could use any pressure cooker.
You can make any casserole with meatballs on the stove too with a lid. When done fold in sour cream to make creamy.
