What makes this recipe stand out is that signature “million dollar” layer. A blend of cream cheese, cottage (or ricotta) cheese, and sour cream melts right into the middle, creating a luscious, velvety texture you won’t find in traditional baked spaghetti. Add in layers of pasta, savory Italian sausage, and plenty of melted cheese, and you’ve got a casserole that’s rich, satisfying, and guaranteed to have everyone going back for seconds.

What Makes It “Million Dollar” Spaghetti?
The name comes from that ultra-rich, creamy center layer that takes this casserole over the top. Instead of just pasta and sauce, this recipe adds a blended layer of cream cheese, cottage cheese (or ricotta), and sour cream right in the middle.
As it bakes, that layer melts into a smooth, velvety filling that makes every bite extra creamy, cheesy, and indulgent. Combined with buttery noodles and a hearty meat sauce, it’s the kind of dish that tastes like it’s worth a million bucks.
✨ Before You Begin
✨ Choose your cheese carefully: Cottage cheese gives this casserole a softer, creamier, slightly tangy filling, while ricotta makes it feel a little more classic and lasagna-like. Both work well, so use the one your family prefers.
✨ Use a marinara sauce you really like: Since the sauce is such a big part of the finished flavor, this is not the place for a bland jar. A good-quality store-bought marinara or a homemade sauce will make a noticeable difference here.
✨ Don’t skip the butter: Those little slices of butter tucked into the pasta melt into the noodles as the casserole bakes, adding richness and helping keep everything moist and flavorful.
✨ Let the cream cheese soften first: Softened cream cheese blends much more smoothly with the cottage cheese and sour cream, which gives you that signature creamy middle layer without lumps.
✨ Plan to let it rest before serving: Give the baked casserole 10–15 minutes to sit before slicing. That short rest helps the layers settle so it holds together better on the plate.

How Million Dollar Spaghetti Is Layered
One of the things that makes this recipe so special is its lasagna-style layering. Here’s a quick look at how it comes together:
- Bottom layer: Buttered spaghetti noodles that create a rich, flavorful base
- Middle layer: The creamy cheese mixture (cream cheese, cottage cheese, and sour cream)
- Top layer: Hearty meat sauce and shredded cheese
Once baked, the layers set into a thick, sliceable casserole that holds its shape beautifully when served.
Million Dollar Spaghetti Ingredients + Key Notes
Pasta: I use Barilla or De Cecco spaghetti. Be sure to cook it in well-salted water so the pasta itself has good flavor. For 1 pound of dried spaghetti, use 5–6 quarts of water and 2–3 tablespoons of table salt.
Onion: I use a yellow onion here for a balanced, savory base.
Garlic: Use fresh garlic for the best flavor. Pre-minced garlic in a jar can taste a little harsh or off in a dish like this.
Sausage: I usually use mild or sweet Italian sausage, but hot Italian sausage works well if you want a little heat.
Marinara Sauce: Homemade is wonderful here, but a good-quality jarred marinara works too. You’ll need about 6 cups total, so plan on 2 jars.
Cottage Cheese: Cottage cheese makes the creamy layer especially moist and velvety. Ricotta works too, but the texture will be a little less creamy.
Cream Cheese: This adds richness and helps create that signature “million dollar” middle layer.
Sour Cream: Sour cream adds tangy, creamy balance and keeps the filling from feeling too heavy.
Dried Italian Seasoning: This easy blend adds herby flavor that works beautifully with the sausage, sauce, and cheeses.
Why This Recipe Works
That signature creamy layer: The combination of cream cheese, cottage cheese (or ricotta), and sour cream creates a rich, velvety center that sets this apart from traditional baked spaghetti.
Layered like lasagna, but easier: You get all the structure and comfort of lasagna without the extra steps—just simple layers of pasta, cheese, and sauce.
Butter adds depth (and prevents dryness): Those small pats of butter melt into the noodles as it bakes, keeping the casserole rich and preventing it from drying out.
Bold, flavorful meat sauce: Using Italian sausage instead of plain ground beef adds extra seasoning and depth, making every bite more flavorful.
Perfect for make-ahead meals: The layers hold up beautifully, making this a great option for prepping ahead or feeding a crowd.
⭐ Pro Tips
⭐ Soften the cream cheese first
Softened cream cheese blends much more smoothly into the cottage cheese and sour cream, giving you that signature creamy middle layer without lumps.
⭐ Let the casserole rest before slicing
Give Million Dollar Spaghetti 10–15 minutes to rest after baking. That short wait helps the layers settle so the casserole slices more neatly and holds together better on the plate.
⭐ Use a marinara sauce you enjoy
Because the sauce plays such a big role in the final flavor, a good-quality marinara really matters here. Homemade is wonderful, but a flavorful jarred sauce works beautifully too.
⭐ Cottage cheese really does work
If you’re skeptical, don’t be. Cottage cheese melts into the filling and creates a softer, creamier texture than you might expect. Ricotta is absolutely fine if you prefer it, but cottage cheese gives this casserole a particularly luscious texture.
⭐ Italian sausage gives the best flavor
Italian sausage adds more seasoning and richness than plain ground beef, which helps this casserole taste especially hearty and satisfying. Ground beef will work, but the flavor will be a little milder.
What to Serve With Million Dollar Spaghetti
Fresh & Crisp Sides
Balance out this rich, cheesy casserole with a refreshing salad. Try my Mediterranean salad, strawberry spinach salad or strawberry salad (both delicious and made with homemade dressings!), or even a retro classic like the 1905 salad. For something ultra-simple, my tomato salad is bursting with fresh flavor, carrot salad is a hit with kids of all ages, or broccoli salad.
Bread Basket Favorites
No Italian-style dinner is complete without warm bread on the table! Pair this casserole with Olive Garden breadsticks, garlic bread, or my fluffy garlic and herb Parker House roll. If you want something a little different, try my super easy beer bread, or uber tender Bisquick rolled biscuit—all perfect for soaking up extra sauce.
Sweet Finishes
Dessert anyone? For a true Italian pairing, serve tiramisu (this tiramisu just maybe the most delicious version you’ve ever had!) or strawberry tiramisu. Cherry pineapple dump cake or heaven on earth cake both come together in minutes and both are super popular on our website. More importantly, they’re delicious with this pasta!
Storing + Reheating + Freezing + Make-Ahead Tips
How to Store
Store leftover Million Dollar Spaghetti tightly covered in the refrigerator for up to 4 days. The casserole will firm up as it chills, but it reheats beautifully and stays rich and creamy.
How to Reheat
- Oven (best method): Cover the casserole with foil and bake at 350°F for 15–20 minutes, or until hot and bubbly throughout.
- Microwave (quick method): Place a portion on a microwave-safe plate, cover loosely, and heat in 1-minute intervals until warmed through. A spoonful of marinara sauce or a small splash of water will help keep the pasta from drying out.
- From frozen: Thaw overnight in the refrigerator, then reheat in the oven or microwave as directed above.
👉 Important: If your casserole is in a glass or ceramic baking dish, let it sit at room temperature before placing it in a hot oven to help prevent cracking.
Can Million Dollar Spaghetti Be Frozen?
Yes — this casserole freezes very well, both before and after baking.
- Before It’s Baked: Assemble the casserole, then wrap it tightly in plastic wrap and foil. Freeze for up to 3 months. When ready to use, thaw overnight in the refrigerator, let it sit at room temperature for about 30 minutes, then bake as directed.
- After It’s Baked: Let the casserole cool completely, then wrap tightly or transfer to airtight containers. Freeze for up to 3 months. For easy meals, portion into individual servings before freezing, then thaw overnight and reheat.
Make-Ahead Tips:
You can assemble this casserole up to 24 hours in advance and refrigerate it until ready to bake.
Before baking, let it sit at room temperature for about 30 minutes so it heats evenly.
👉 Good to know: The pasta will absorb some sauce as it sits. For a creamier result, add an extra 1/2 to 1 cup of marinara when assembling.

Million Dollar Spaghetti
Ingredients
- 16 ounces dried spaghetti noodles
- 1 cup (1 medium) yellow onion chopped
- 4 cloves garlic minced
- 1 1/2 pounds sweet Italian sausage casing removed
- 6 cups homemade marinara sauce, -divided, or 2 (24-ounce) jars of marinara sauce
- 8 ounces cottage cheese or ricotta cheese
- 8 ounces cream cheese
- 1/4 cup sour cream
- 3 teaspoons dried Italian seasoning
- 3 cups mozzarella shredded-divided
- salt
- pepper
- 1/2 cup butter cut into slices-divided
Instructions
- Preheat oven to 350°F (177ºC).
- Bring a large pot of water, with 1 tablespoon of salt, to a boil. Cook pasta (16 ounces) according to the package. Drain well, then return pasta to the original pot, and add 3 cups or 1 jar of prepared marinara sauce and combine. Set aside.
- In a large skillet, heat 2 tablespoons of olive oil over medium heat until it shimmers. Add onion (1 cup) and garlic and cook until they begin to soften about 5 minutes. Add sausage to skillet, and brown, crumbling sausage (1 1/2 pounds) with a wooden spoon. Cook until there is no longer any pink in the sausage. Drain well. Add the remaining 3 cups or 1 jar of marinara sauce to the skillet. Set aside.
- In a medium mixing bowl, combine Cottage cheese or ricotta cheese (8 ounces), cream cheese (8 ounces), sour cream (1/4 cup), 1 cup mozzarella, and Italian seasoning (3 teaspoons). Set aside.
- Place half the sliced butter in the baking dish. Spread half the spaghetti in the dish, then spread the cheese mixture evenly over the spaghetti. Top with the remaining butter slices. Spread remaining spaghetti over cheese mixture. Pour tomato meat sauce evenly over the top layer of spaghetti.
- Top with remaining mozzarella and bake in the preheated oven until casserole is heated through about 35-45 minutes.
Notes
- Does that say cottage cheese? Yes, it does. Before you dismiss this recipe, hear me out: cottage cheese is a mind-blowing ingredient that far too many people avoid, thinking their food will turn out tasting too “curdled.” That is not the case at all! More importantly, its texture changes when it melts to something wonderful.
- Cottage cheese adds a fabulous creamy texture to foods as well as hearty servings of protein. But if it still seems just too odd for you, ricotta cheese is a perfectly acceptable substitute! It just won’t be quite as creamy, though. Use the same amount as the cottage cheese.
- Spice it up! The dried Italian seasonings and the sausage, as well as the extra spices you add to this dish, will give this casserole that zesty Italian kick — but try tossing in a handful of chopped fresh basil, if you have any on hand, especially as a finishing garnish.
- Meat: I use Italian sausage in this recipe, and man, is it good. The extra flavor added by that sausage is simply outstanding, and really makes this recipe a true crowd-pleaser.
- If you or your audience are not particularly fond of Italian sausage (like my sister, Alise!!), you can absolutely use ground beef instead, but, I don’t think the final flavor is as robust.













Amazing every time!! I have a novice question. If I used penne instead of spaghetti noodles, should I use the same amount or more or less? Thanks so much!
Hi Erika. I’m so happy your enjoying this recipe. You can use the same amount of penne, but expect a slightly different mouthfeel. Penne will create a less cohesive dish but it’ll still be creamy and flavorful. Thanks so much for the 5 star rating. I hope you find lots more recipes her that you love!
VERY GOOD!
So happy your enjoyed, Sara! Thanks for the 5-star rating!!
My family loves this, I also make it for church potlucks.
I make it the night before and heat it the next day, it is wonderful, never any left over.
That’s amazing, Betsy! Thanks for the feedback and rating!
I have been making this for over 2 years now. It is a family FAVORITE! My only suggestion is that people make sure their 9×13 is BIG and DEEP because… believe it or not… not all 9×13 pans are the same size. LOL And this fills mine to overflowing every time. I just make a second small foil pan to go with it until I get a deeper 9×13. 😉
I do have a question though…. what would you suggest for making this in a crockpot? It was requested for a holiday potluck next week and I feel like there SHOULD be a way to do this and still get similar results…. Thoughts?

Hello,
Everyone raved about this recipe! Very creamy and satisfying.I found that it need a bit of heat.
Next time I’ll add some hot pepper flakes. Also perhaps a spicier sausage. I’ll experiment!!
Thank you for this delicious recipe, it’s a keeper for sure.
Wow, thank you so much, Mary! I’m happy it was a hit. 🙂
I like that you added pepper flakes!
I cannot wait to try this recipe this weekend, I was wondering if I could bypass all the butter or use half of the butter slices?
Thanks
Hi Marqueta. Sure you can. 🙂
Made this a few weeks ago. Delicious! I’m sure I can assemble this a day ahead and cook it the next day. Have you tried?
Hi Marshelle. Yes that will work!
Unique, tasty, and crowd pleasing.
Wow, thank you so much, Kenneth!
I made a homemade Alfredo sauce instead and the marinara and oh my goodness it is heaven in your mouth.
I love this recipe as much as my family does. I make this often and leftovers are better the next day.
I agree! It’s better the next day. I’m glad it was a hit. Thanks, Julie!
Can you freeze it?
HI, Robin!
Absolutely! Many casserole baking dishes come with their own attachable airtight lid. If yours doesn’t have one, simply spoon it into an airtight container or resealable plastic bag, and store in your freezer for up to 1-2 months.
Remember, frozen pasta will get softer, so there will be a textural change.
To Freezer Before Its Baked
1. Assemble the recipe through step 5.
2. Wrap the baking dish tightly with plastic wrap first, then aluminum foil. (Remember, plastic wrap sticks best to itself. Start with a long piece of plastic wrap that goes all the way around the baking dish.)
3. Thaw the casserole overnight in the fridge.
4. Bake it!
Enjoy ♥
Delicious. Best spaghetti I’ve ever made. Must try.
Hi, Lily! Wow, thank you so much, I’m so happy you like this! 🙂
This was fantastic! Easy to make . I used a deep 9×12 casserole dish.
Yum yum
Thank you so much, Lj 🙂 So happy you like this!
How big of a baking dish do you need? I’m an inexperienced cook so need a bit of help, but this looks like a good recipe.
Hi, Sue! I use a 9×13-inch baking pan. I hope you enjoy this spaghetti. Let us know how it turns out. Thank you! 🙂
