Holly’s Recipe Highlights: Million Dollar Spaghetti
- Flavor: Zesty marinara, savory Italian sausage, and three creamy cheeses give every layer rich, savory flavor.
- Why Make It: It delivers the layered look of an easy homemade lasagna without arranging individual noodles.
- Make Ahead: Assemble this up to a day ahead and keep it refrigerated until ready to bake. It makes dinner easier when feeding family, bringing a dish to a potluck, or serving a crowd.
Cook Time: 1 Hr 25 Mins Servings: 12 Cooking Method: Sauté and Oven
Ingredient Notes
- Spaghetti: Cook the pasta until al dente, as it will continue cooking in the oven. Swap in any medium pasta, like penne, rigatoni, or rotini.
- Italian Sausage: Ground beef or turkey work well too, but season the meat more generously to build the same depth of flavor as Italian sausage.
- Marinara Sauce: Choose a sauce you already enjoy because its flavor carries through the entire casserole. Or try making a homemade marinara sauce instead.
- Cottage Cheese: Cottage cheese makes the center creamy while adding a little structure to the layers. Replace with ricotta for a smoother, more traditional lasagna-style filling.
- Cream Cheese: Let the cream cheese soften to room temperature so it blends smoothly with the other filling ingredients without lumps.
- Sour Cream: Use full-fat sour cream for the richest, creamiest texture.
How to Cook Million Dollar Spaghetti
- Cook the pasta, and stir in the marinara sauce.
- In a skillet, sauté the sausage, onions, and garlic.
- In a bowl, prepare the cheese filling (full recipe below).
- In a casserole dish, add the spaghetti, then layer with the cheese mixture and more spaghetti.
- Top with the meat mixture, sprinkle with cheese, and bake.
Save Those Million Dollar Leftovers
- Keep leftovers in an airtight container for up to 4 days and in the freezer for up to 3 months.
- Thaw overnight in the refrigerator. Reheat individual portions in the microwave until heated through, or cover and warm them in a 350°F oven.

Million Dollar Spaghetti
Million dollar spaghetti layers saucy pasta, savory Italian sausage, and a rich cream cheese filling under plenty of melted mozzarella. It's an easy, hearty casserole made to feed a crowd.
Ingredients
- 16 ounces spaghetti
- 1½ pounds Italian sausage casing removed, or ground beef or turkey*
- 1 large yellow onion chopped
- 6 cloves garlic minced
- 2 (24 ounce) jars marinara sauce or spaghetti sauce, divided
- 3 teaspoons Italian seasoning divided
- 8 ounces cottage cheese or ricotta cheese
- 8 ounces cream cheese room temperature
- ¼ cup sour cream
- 3 cups shredded mozzarella cheese divided
- chopped fresh parsley and parmesan cheese for garnish, optional
Instructions
- Preheat the oven to 350°F. Grease a 9×13-inch baking dish.
- Bring a large pot of salted water to a boil. Cook the pasta al dente according to package directions. Drain well and return the pasta to the original pot. Add 24 oz of prepared spaghetti sauce and toss to combine. Set aside.
- In a large skillet, combine Italian sausage, onion, and garlic over medium-high heat. Cook until no pink remains and the onion is soft. Drain excess fat. Stir in the remaining 24 oz of spaghetti sauce and 2 teaspoons of Italian seasoning. Set aside.
- In a medium mixing bowl, blend cottage cheese (or ricotta), cream cheese, sour cream, 1 cup mozzarella, and 1 teaspoon Italian seasoning using a hand mixer. Set aside.
- Spread half of the spaghetti in the prepared baking dish, then top with the cottage cheese mixture. Spread the remaining spaghetti over the cheese mixture. Pour the meat sauce evenly over the top.
- Bake uncovered for 35 to 45 minutes, until the casserole is heated through, adding the mozzarella on top for the last 20 minutes of the cook time.
- Rest for 15 minutes before serving.
Notes
*If replacing the sausage for ground beef or turkey, add additional seasoning to the sauce. For a little kick, add ½ teaspoon red pepper flakes.
This casserole can be prepared 24 hours in advance. If made ahead of time, let it set at room temperature for at least 30 minutes before baking. Add 15 minutes to the baking time.
Store leftovers in a covered container in the refrigerator for up to 4 days.

It was great family loved it i even snuck in mushrooms and onions
This was a huge hit and the dish is so filling!!!
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!
Awesome to hear it has been such a success!
Made for tonight looms and smells awesome! Can’t wait to eat! We added mushrooms and black olives!
Those sound like delicious additions! I hope your family loved the recipe!
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.
I am so glad that you enjoyed the recipe!
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.
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.
Loved the recipe and was excited to add my our touches. As I like to sneak veggies in everything!
To the meat I added crushed red pepper and a small amount of leftover broccoli finely chopped
To the cheese I added pepper, more crushed red pepper, finely chopped spinach, and used pepper jack cheese
To the spaghetti I buttered, salt, peppered and yes added more crushed red pepper before adding the sauce
Topped with mazzerela, pepper jack and cheddar. It was amazing and didn’t need to any sides since the veggies were already added! Froze leftovers for an easy grab and go lunch. Thank you so much for a beautiful start!
Your additions sound yummy! Thanks for sharing.
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.
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!
Hi Sandy,
I am so glad you enjoyed this recipe!
Do I need to cover with foil and bake or no ?
You can cover with foil and uncover during the last few moments in the oven!
Will try thus abb more good recipes fast and easy I have a large family need help
Looks fantastic. I think I gained 5 lbs. just looking at the pictures.
Haha thanks!
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!
I’m so glad your family loved this recipe!
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.
I’m so glad you enjoyed it!
Sounds great! The spaghetti pie I’ve made in the past called for eggs to hold the noodles together. So the noodles hold its form when cutting without the eggs?
Thank you
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!
So glad you loved it! It is one of my favorites as well.
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 !
That sounds like a delicious substitute!
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.
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.
I am so glad you liked the recipe, Jenny.
