Million Dollar Spaghetti Casserole is an easy hearty casserole that is both budget-friendly and easy to make. This casserole is simple and a delicious way to feed a family or a crowd!
When I have a hungry family to feed, I break out an old fashioned casserole. Hearty casseroles are designed for that kind of work! Potlucks, large family gatherings… whatever your need, a casserole will be there for you. This recipe for Million Dollar Spaghetti is one of my all time favorite casseroles. It’s basically an easy combination of baked spaghetti and lasagna. (I know, it sounds delicious doesn’t it?)
As only the best family recipes are, this million dollar spaghetti is budget-friendly. It yields a ton of food, and the ingredients aren’t complicated or expensive. In that way, this casserole is a fantastic part of your weeknight meal routine.
I like using Italian sausage for the extra flavor, but in a pinch you can substitute regular ground beef.
The leftovers for this dish are tremendous. The pasta softens up a little bit when reheating, but the flavor is just as good as when it was fresh out of the oven.
Million dollar spaghetti casserole is an ooey-gooey, hearty, rich comfort food. You’ll enjoy every bite, and—if you’re like me—you’ll start looking for the next time you can make it. Enjoy.
Cheese: You can use either cottage cheese or ricotta cheese for this recipe. Whichever sounds better to you! I’m partial to the cottage cheese because I think it lends the final recipe a great creaminess.
Pasta: Spaghetti noodles are just one of the many different kinds of pasta that will work in this dish. I love using ziti or rigatoni noodles on occasion.
Serving: My advice is to serve this recipe with garlic bread and salad. They make an awesome first course while the casserole is cooling.
Baking: Million Dollar Spaghetti Casserole can be made up to 24 hours ahead of time. Ensure you cover & refrigerate the pan. Once baked, allow the casserole sit out and cool for a good 10-15 minutes before serving.
Freezing: To freeze the casserole, wrap it in plastic wrap first, and then aluminum foil. Let it thaw overnight in the fridge before baking.
