Southerners aren't afraid to make anything into a casserole, and this slow-cooker version of our crowd-favorite spaghetti casserole makes it even simpler to throw together for supper. Consider this dish like taking your go-to quick-fix pasta recipe and turning it into a casserole that can double as leftovers all week long. Thanks to store-bought tomato sauce and canned tomatoes, this spaghetti casserole recipe tries to make your life just a little bit less complicated. And did we mention it's only eight ingredients? We topped the casserole with both Parmesan and Cheddar cheeses to guarantee a warm, gooey finish. Before serving, all this pasta bake needs is some crusty garlic bread. Don't ever wonder what's for dinner again because the whole family will love this slow-cooker spin on a childhood favorite. Ingredients 2 pounds ground round 1 medium onion, chopped 1 large clove garlic, minced 8 ounces uncooked spaghetti, broken into pieces 1 (26-oz.) jar tomato-and-basil pasta sauce 1 (14.5-oz.) can diced fire-roasted tomatoes 1 teaspoon dried Italian seasoning 2 cups (8 oz.) shredded sharp Cheddar cheese Freshly grated Parmesan cheese Directions Cook ground round and onion in a large skillet, stirring until beef crumbles and is no longer pink; drain meat, and return to skillet.
