I love easy & delicious recipes like this Meatball Parmesan Casserole. You only need 5 ingredients, it’s ready in minutes & it’ll feed a crowd for cheap. I’ve used frozen meatballs in this delicious dish; however – you could certainly replace them with freshly made meatballs if that’s what you prefer. When I make meatballs, I make up a whole bunch at one time for the freezer… but I haven’t done that in some time now. I’ve been slacking on the homemade meatballs for sure so for me lately, it’s frozen meatballs to the rescue.
