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.

Steps for making Million Dollar Spaghetti

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.

Recipe Notes:

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.

    1. We use 2 jars of pasta sauce to equal 48 ounces in total. We say divided because 24 ounces is added in step 2 and the additional 24 ounces is added in step 3.

  1. Made this for the family last night and it was a slam dunk! This will definitely go into our regular dinner rotation.5 stars

  2. Great recipe all the family enjoy especially my granddaughter !
    Only thing I find is 16oz of spaghetti noodles is WAY too much. Made a 9×13 pan and 9 inch pan and still threw out some noodles!
    I did use 1/2 mild Italian sausage meat and 1/2 extra lean hamburger as my grandson loves the taste of the sausage!!

  3. ALWAYS TAKES ME LONGER TO PREPARE!! I have no doubt about the taste of this. I have 2 foreign exchange students, both 16 year old boys at the YMCA while I cook.
    They haven’t complained yet about my cooking!!!
    Bad thing is, I have way less left overs for my work lunches!! Oh well, I’ve raised 7 kids already so I know what it’s about.5 stars

  4. I love this recipe….I have made it several times and it is always a big hit. The leftovers are just as good as the first time. I highly recommend trying this if you haven’t already.5 stars

  5. This is so delicious! My hubs doesn’t care for sour cream so I just increased the cottage cheese. Oh my goodness!!
    It does make a huge amount of foot as you stated. We enjoyed it through the week and froze some too. Great for football nights or leftovers! Thanks for the recipe!5 stars

  6. It was OK. I don’t think I liked the taste of the cream cheese in this recipe so I won’t make this again. I made as is but substituted ground beef for the sausage. I don’t think that the sausage would have helped hide the cream cheese taste. Don’t get me wrong I love cream cheese but it just didn’t work in this dish for me.3 stars

  7. Great recipe. Not sure why so many question using butter. It’s a very common ingredient added at yhe end ofmany high end chef made a spaghetti sauces. Usually added just be f ore serving. Considered a secret ingredient.5 stars

  8. This is by far the best spaghetti casserole I have tried thus far. The only thing I did different was I added a pound of ground beef and reduced the sausage to a pound of ground sweet Italian. It was delicious!5 stars
