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.

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. What size baking dish?

  2. This recipe “Million Dollar Spaghetti Casserole” sounds great. My question is the directions say to add the Italian seasoning in 2 different places, with the meat and also with the cheese mixture, however it does not say divided after the amount of Italian seasoning. So I’d like to know the right amounts. Thank you and I’ll be checking out your blog also. Thanks, Ginger

  3. Outstanding! I used half ground turkey and half spicy italian turkey sausage because it was what I had on hand. I followed the rest of the recipe exactly. I can easily say this was the best dish I have tried in a very long time. Winner all the way! Thank you for sharing your recipe!

  4. I gotta try this! It looks wonderful. Thank you for sharing.

  5. Yummy! Can you please add the size baking dish in the directions?

  6. Do you have a favorite jar sauce that you like to use in this recipe?

  7. What does the butter?

  8. could you use hamburg instead of sausage,

  9. I will definitely be making this dish. I imagine that I’ll use a pound of quality Chuck Beef and a half pound, or so, of bulk Italian Sausage. I may add some Mushrooms, and julienned pimientos. Have to wait until we can dig out of the snow though. Thanks, the recipe looks great!

  10. Is this really only 6 servings? Just seems like it would serve more people.

  11. All those recipes look wonderful. Thank you for sharing!

  12. have you baked it and then frozen the leftovers? i just made it and it is delicious! i just didn’t know if you’d experimented with that.

    • Yay! I’m glad you liked it! Freezing the food can take away the texture and flavor that makes our recipes tasty!

  13. Made this for dinner with just ground beef and the kids devoured it. Thanks!

  14. Made this tonight everyone loved it. I disagree with the amount of servings. I believe it should be 10-12 instead of six.

  15. can’t wait to try this !

  16. I don’t like cottage cheese could I substitute something else and what would you recommend if so

  17. When making ahead, do you bake it before refridgerating or just assemble and bake when serving?

  18. Have it in the oven now…. can’t wait!

  19. This dish looks good, and I’m gonna try it in a few days………….

  20. I added mushrooms,red pepper and black olives to this ……amazing!!!!!

  21. Hello! This was delish!! Absolutely loved it but it made 2 13×9 casserole dishes, not one. I am going to half the recipe next time. I cook for 2 and had way more than 6 servings and I stuck to the recipe exactly.

  22. I made this I did a few changes 1/2 ground turkey half Italian sausage. I also added crushed red peppers to my meat along with the Italian seasoning. Finally for an extra cheesy topping I mixed t mozzerlla and mild cheddar. My family loved it.

  23. Making this tonight. I had to improvise and add extra sour cream and mozzarella cheese because my ricotta cheese had expired. I pray it turns out right !

  24. Million Dollar Spaghetti Casserole…made it today….used half Italian sausage and half ground beef, and used cottage cheese. It was loved by all of us. Served green salad and French bread..yummm. It is definitely a keeper, will make it again!

  25. My husband and I really liked this recipe, reminiscent of baked ziti. My first recommendation is use something bigger (and deeper) than a 9 x 13 Pyrex plate. I had to bake this on top of a pan because I knew it would bubble over. My own tweaks were that I used a jarred sauce that had mushrooms in it, only used about 3 tbs. of butter in the bottom of the pan and omitted the rest of the butter since this is pretty rich already. I did not have sour cream so I simply thinned the cheese mixture with a little half and half. In addition to the mozzarella, I also added a small amount of grated parmesan to the cheese mixture and to the top. This would be a great dish to make for company with a good salad, good loaf of Italian bread or garlic bread and a good red wine. This will be a keeper.

  26. This was so delicious! I made it exactly as the recipe stated and my whole family loved it, even my picky husband. Thanks so much!

  27. Looks fantastic. I think I gained 5 lbs. just looking at the pictures.

  28. Do you happen to have the nutritional values for this recipe?

  29. Will try thus abb more good recipes fast and easy I have a large family need help

  30. Do I need to cover with foil and bake or no ?

  31. Thank you so much for the recipe! This is now my go to recipe for gatherings and meal trains. I’m taking it today to a friend whose hubby just had surgery. The casserole, salad, bread and a nice red will comfort everyone!

  32. Hi. My family despises both ricotta & cottage cheese is there anything that can be substituted, like maybe cream cheese? Thanks!

    • I have made the recipe as written, however if you decide to try a substitution let me know how it turns out.

    • Hi Gina,
      Just found this recipe, saw your comment, and wanted to recommend you try making a white sauce to replace the ricotta & cottage cheese. Just melt 3 Tbsp. butter, add 3 Tbsp. flour, and stir to combine. Then just add 1 cup milk and stir till thickened. It should do the trick for you.

  33. This recpie look amazing !!! I like to make it but i dont eat meat at all, can i make it without the all part of the meat ?

    • I have only made this recipe as written. If you decide to try it without meat, let me know how it turns out.

  34. Love this! I made it with macaroni noodles and used an Italian cheese blend with the mozzarella and used four cups. The next time, I will probably add a bit more seasoning and a bit of sugar. Thanks so much for the great recipe.

  35. Made for tonight looms and smells awesome! Can’t wait to eat! We added mushrooms and black olives!

  36. I made this a couple of weeks ago and this dish is amazing!!! I’ve gotten so many compliments on this dish, my co-workers and friends were asking me to bring them a plate :) Will be making this again!

  44. Made this tonight as it sounded soooo good! I thought the ricotta/cream cheese/sour cream mixture was extremely overpowering. You couldn’t even taste the tomato sauce over the cream cheese. I double checked the ingredients to see if I put too much but no, I did it as listed. I would advise cutting that part in half. I think then it would be delicious.

  45. This was pretty tasty, however we found it to be too creamy and I even forgot to add the cottage cheese. Great base recipe that I feel I can modify with some healthier things and we can still enjoy.

  46. I love cream cheese, but the cheese layer was so thick and overpowering that nobody would eat it until I scraped it off. The second time I made it I used Ricotta, one egg, Italian seasoning, parsley flakes, mozzarella and parmesan. It was MUCH better. This doesn’t need an inch thick layer of dairy!

  47. This was very good, my husband & I really liked it!! I wish I would’ve cut the recipe in half, since there’s only the 2 of us, but it’ll be great leftovers for days I don’t care for Italian sausage so I used Andouille sausage….yum!! I did use Cottage cheese instead of ricotta, because I already had it. Would recommend this recipe for sure, I’m trying to share it on Facebook too

  49. I made this and my family loved it! It’s very filling and it makes a huge dish, so we will be having left overs for a while. My husband is a farmer and even chose to take it on the tractor today.

  50. I made this and it made a ton! I fed 5 adults and two children… And there were leftovers! It was good the first night that I made it, but the leftovers were amazing the next day! Definitely a new favorite.

  51. Could this be made with spaghetti squash or spiralized zucchini?

  52. I made this last night for the first time and it came out great . My hunnybun is a picky eater and he loved. Thank You for sharing

  53. Have you ever made it with two pounds of sausage? If so, what adjustments were made? What do you recommend if morw meat is added

  54. How much would I need to alter this recipe if I use two pounds of Italian sausage and meatballs?

  55. Made the spaghetti casserole for the first time. Family absolutely loved it.Thank you.

  58. Absolutely Delicious!!!

  59. I love this recipe! I cut the recipe in half and used a spring form pan, cut like a pie. You see all the beautiful layers.

  60. I made this a few nights ago and being so good we had no problem eating it each night till gone. My husband said this is a restaurant dish!! His highest praise for a dish. So good! I looked at my 9 by 13 pans and thought I better get out the Pyrex Khaki 9 by 13 one which is about 4 1/2 inches deep and so glad I did. It was filled to the top. I used cottage cheese when I made it. Reheating- I put it in my double boiler pan with the insert that has holes and lined it with foil. Steaming the portions was perfect. This recipe is not heavy to the stomach, really light considering all the goodies in it. Just the 2 of us and we ate it till every bite was gone and loved it!! I would serve this to dinner guest with no reservations at all.

  61. Made this tonight exactly as recipe stated – loved it – would certainly make this dish for guests

  62. I would love to make this for a potluck. Can this be done in the crockpot to stay warm until lunch? 

  63. Do I cover with foil while baking?

  64. Made this for a company party ,everyone loved it. Will be handing out the recipe. Thank you it was a huge hit.

  65. This should be renamed BILLION dollar spaghetti!!!!! It made waaaaay more than 6 servings so I had to give away lots of it…everyone that I shared it with said it was AWESOME. I followed the recipe exactly, I may use spicy sausage next time or add red pepper flakes just as matter of personal preference. I recommend using a deep dish casserole dish, a normal baking dish might be to shallow.

  66. My team mate made this for our pot luck and it was such a hit! She made it in the crock pot! She sprayed the crock pot with pam then followed the recipe. She plugged it in at the office and by lunch it was perfectly cooked and so yummy.I’m making it tonight

  67. Very tasty! My family loved it! There were four of us, and we didn’t even eat half the first night, so I would say it feeds 8 or more people, easily. Looking forward to the leftovers!

  68. Good recipe. A few tweaks according to my taste. Instead of all mozzarella I used half mozzarella and half cheddar. Also added salt, pepper, and creole seasoning to both the spaghetti and meat mixtures. Came out very good.

  72. Yuk! I’m hoping the guys at hubbys shop will eat it, if not then garbage it is. If I could do it over I’d leave out the cream cheese and sour cream. No Italian sausage just hamburger meat. Add Colby jack to the motzarella. I’m not sure the Italian seasoning did anything at all really so I guess I’d leave that.

  73. Very tasty meal, the only thing I would do different was not fully cook the spaghetti, to prevent the casserole from being to mushy. Served this with a tossed salad. Froze the left overs for a second meal.

  74. Overall, this was good. If I make it again I would cut the butter in half, at least. Also, I added mushrooms to the spaghetti and sauce and black olives to the sausage and sauce. The other thing I might do is cut the cream cheese down and increase the cottage cheese. It all just was a little too rich for me.

  76. I’m wondering what temp to heat the oven.  Sounds delicious and I look forward to trying it.  Thanks!

  77. Have you tried this recipe with half ricotta and have cottage cheese?

  78. I used half ground beef/half sausage and added shredded veggies (carrots, red bell pepper, garlic, mushrooms, onion, zucchini, summer squash) to the meat sauce.  I had family over for dinner and my daughter (she’s 7) as well as my mom (she’s 67) both declared this was their favorite meal from now on. :)Terrible amount of calories – definitely an indulgence – but worth it!  So good!!

    • So glad you enjoyed it Margie! I have only tried the recipe as written, but your additions sound delicious. It is my favorite too!

  79. I’m gong to make this for my baby shower in 3wks. I would like to make it the day before. What is the make ahead recipe? How long should I bake it after its been refrigerated?

    • In the written information, it says 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. Enjoy, Kayla!

      • So Do I fully cook it then refridgerate it? How long should I bake it again after refrigeration?

        • You can make this ahead of time if you’d like. I would suggest leaving it at room temperature for about 30 minutes before baking and then cook as directed in the recipe.

      • Looks like my post was deleted. To make ahead do I cook it entirely? How long should I bake it after refridgerating? I’m thinking the noodles will be mushy if i overcook it.

        • Your comment is above, you can make this ahead of time if you’d like. The noodles do come out perfectly, you’ll want to cook them al dente when you boil them.

  80. I made this today. It is yummy! I forgot to pick up the cream cheese so I doubled the ricotta (cottage cheese is too thin and watery). I halved the recipe since it’s just me and the hubster at home these days. One question – Nowhere in the recipe does it state to mix together the pasta and the sausage. So I did since that’s what the photo appears to show. I drove myself crazy looking for what to do with the sausage thinking I surely missed it when reading the recipe. Also, we only use Mezzetta pasta sauces. No sugar all natural ingredients and really taste homemade. They have several varieties including a spicy one.

    • In step #2 a jar of sauce is added to the spaghetti. In step #5 the meat sauce is poured overtop of all. I’m sure mixing it would be just fine too though!

      A spicy sauce would be great in this recipe.

  81. Wow!!! This dish is amazing! Only thing I changed is I decreased the Italian seasoning to 1 1/2 tsp. as I find it is a rather strong spice for me and my family. 
    Truly is the ‘best spaghetti pie’ recipe I have found. Thanks!

  82. Amazing recipe! Thank you so much!

  83. This is an awesome twist to the usual spaghetti! I made it for the first time about 6 weeks ago, and have made it 4 times since then! It’s very filling, we always have leftovers…and that’s after my husband, my teenage son, my uncle (all 3 are hard working big eaters), and myself have ate! A definite keeper in my family!
