Ingredients in Million Dollar Spaghetti
Meat: I like using Italian sausage as it has lots of flavor, but in a pinch, you can substitute ground beef or ground turkey. If substituting the sausage, I would recommend adding extra seasoning to the sauce.
Sauce: This recipe uses pasta sauce as the base to keep it quick and easy. You can use homemade marinara sauce or your favorite jar of sauce. Feel free to stir in fresh herbs if you’d like!
Cheese: The cheese layer is made with either cottage cheese or ricotta cheese. I prefer cottage cheese because I think it adds so much creaminess to the recipe.
Pasta: We most often make this with spaghetti but other types of pasta can be used. Try ziti or rigatoni noodles.
Serving Suggestions
Million dollar spaghetti is a hearty casserole that is a complete meal on its own. You can pair it with garlic bread and a fresh salad if you’d like.
Leftovers and Prep Ahead
The leftovers of this casserole reheat well! The pasta softens up a bit when reheating, but the flavor is just as good as when it was fresh out of the oven.
Prep Ahead: Million Dollar Spaghetti Casserole can be made up to 24 hours ahead of time. Remove it from the fridge at least 30 minutes before baking and add an additional 15 minutes to the baking time.
Freezing: To freeze the casserole, wrap it in plastic wrap first, then aluminum foil. Let it thaw overnight in the fridge before baking.

Great recipe as is for a special meal. I love that you still have the nutritional breakdown so that we can all adjust to accommodate special dietary restrictions (salt, carbs, cholesterol). Many recipes no longer provide this information and I find it frustrating and time consuming. I bought your recipe book, totally worth it!
It’s great you find the nutritional info helpful! I’m so glad you love my book Bex (if you’re so inclined a review on Amazon would mean so much)!
If you use Italian pork sausage instead of Italian sausage with casing removed, do you still add 2 tsp. Italian seasoning?
Sure you can and yes, I would recommend keeping the seasonings the same.
I had 18 people for Christmas lunch, so I did 2x the recipe! It was delicious and I received rave reviews for the casseroles I had put together the day before and baked while the revelers were en route for lunch! Served with salad and Tiramisu for an easy Italian Christmas lunch.
Rush!! can this be frozen before baking? Making it. cleaning it up. and freezing it would really help my holiday schedule. Thank you in advance!
Yes, this freezes well. To freeze the casserole, wrap it in plastic wrap first, then aluminum foil. Let it thaw overnight in the fridge before baking—you will need to add extra baking time if it is cold from the fridge.
hi! have you used reduced fat sour cream and/or cream cheese? any issues with using either? thanks!
Those should both work just fine in this recipe.
This is an awesome recipe and EVERY TIME I’ve served it, people have asked for the recipe. Thank you!
Could you make this in a disposable foil pan? Would it change the cook time? I want to make it for a friend having surgery and don’t want them to worry about returning/cleaning a dish. I’ve made this many times before and it’s always a hit!
It should work well in a foil pan but make sure they place the foil pan on a baking sheet for proper heat dispersement during baking.
Wonderful, Wonderful Recipe.
This is the best baked spaghetti recipe I have tried. It was well loved by my family.
