What’s a flavor combination so essentially American that, when made into a casserole, it can proclaim itself The Ultimate American Casserole? If you said meat and potatoes, you’d be right! The stripes in this flag of flavor come from a rich, savory, beefy layer of ground meat and tomatoes, infused with even more meaty flavor. Serving as the stars is a bed of fluffy, creamy, and tangy mashed potatoes mixed in with sharp cheddar cheese! The Ultimate American Casserole is the kind of dish you can salute with pride as you grab a fork and dig in!
