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.

Those sound like fantastic additions Mayetta!
This dish looks good, and I’m gonna try it in a few days………….
I hope you enjoy it!
Have it in the oven now…. can’t wait!
Let us know how it turns out!
When making ahead, do you bake it before refridgerating or just assemble and bake when serving?
You can assemble and refrigerate this recipe before baking.
I don’t like cottage cheese could I substitute something else and what would you recommend if so
You can use ricotta cheese.
can’t wait to try this !
Made this for dinner with just ground beef and the kids devoured it. Thanks!
I’m so glad your family enjoyed this recipe!
Made this tonight everyone loved it. I disagree with the amount of servings. I believe it should be 10-12 instead of six.
I’m so glad your family enjoyed this recipe!
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!
All those recipes look wonderful. Thank you for sharing!
Is this really only 6 servings? Just seems like it would serve more people.
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!
could you use hamburg instead of sausage,
Yes you can.
What does the butter?
The butter on the bottom keeps it from sticking as well as adding flavor throughout.
Do you have a favorite jar sauce that you like to use in this recipe?
I often use the Kirkland pasta sauce from Costco or Classico. Any type will work great i this recipe.
Yummy! Can you please add the size baking dish in the directions?
Great suggestion, I’ve added it.
I gotta try this! It looks wonderful. Thank you for sharing.
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!
I am so glad you liked this recipe, Pat!
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
Great question. I would add 2 teaspoons to the tomato mixture and 1 teaspoon to the cheese mixture. I have updated the recipe. Enjoy!!
What size baking dish?
This will fit in a 9×13 pan.
