When it comes to pasta, it doesn't get much better (and easier!) than classic spaghetti, and the family-friendly dish can be so much more than al dente pasta noodles drenched in jars of tomato sauce. 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.
Spoon half of meat mixture into a lightly greased 5-qt. slow cooker. Top with spaghetti. Spoon remaining half of meat mixture over top.
Combine pasta sauce, diced tomatoes, ½ cup water, and Italian seasoning. Pour mixture over meat, and sprinkle with Cheddar cheese.
Cover and cook on Low 4 hours. Let stand 10 minutes before serving. Serve with Parmesan cheese.
