If you've tried mashed potatoes with tomato sauce (a good homemade old-fashioned dish of Gnocchi pasta), then you will love this easy casserole taste as it's similar in flavor to meat sauce with taters.
Pasta is the usual ingredient in this type of casserole, and the mashed potato meatball combination is fantastic with all that melted cheese on top.
It really is pure comfort food and is very filling so it's perfect for a hungry crowd and super easy to make.
This recipe is so easy and comes together with just a few ingredients if you buy all store-bought, this is the perfect weeknight meal, especially after a long day tedious day!
We love Italian meatballs, meatballs on pizza, and even meatball appetizers in a delicious glazed sauce for game day and events!
Of course, if you love meatballs you must also try our recipe for Porcupine Meatballs made with rice in them, they're so delicious!
