Save on Pinterest There's something about a casserole that makes people linger at the dinner table longer than they planned. I discovered Million Dollar Spaghetti at a potluck where someone arrived with this bubbling, golden-topped dish, and within minutes there was a line forming. The name made me laugh at first—until I tasted it and understood why it earned such a bold title. It's the kind of food that feels like a celebration in a baking dish, humble but undeniably luxurious, and now it's become my go-to when I want to impress without spending hours at the stove.
I'll never forget the first time I made this for my sister's birthday dinner—I was nervous about timing everything, but the casserole became my secret weapon. While everyone was engaged in conversation, I had this beautiful dish quietly doing its thing in the oven, filling the whole house with an irresistible smell of meat, cheese, and herbs. When I pulled it out and the cheese had that perfect golden-brown finish, even my notoriously critical brother asked for seconds before anyone else had taken their first bite.
Ingredients
- Spaghetti (1 pound): Don't use the thinnest pasta you can find—a standard spaghetti has just enough body to hold up to the creamy layers without turning mushy in the oven.
- Ground beef and Italian sausage (1 pound each): The sausage adds a subtle spice and depth that ground beef alone can't achieve, but you can use all beef if that's what you have on hand.
- Yellow onion and garlic (1 medium onion, 3 cloves): These are your aromatic foundation, and mincing them fine ensures they distribute evenly through the meat sauce.
- Marinara sauce (24 oz jar): Use a good quality sauce you'd actually eat straight from the jar—it's the backbone of flavor here, so don't skimp.
- Italian herbs, salt, and black pepper: These simple seasonings enhance the marinara without overpowering it; measure them out before you start cooking so you're not adjusting as you go.
- Ricotta cheese, Alfredo sauce, sour cream, and egg (15 oz ricotta, 1 cup Alfredo, 1/2 cup sour cream, 1 large egg): The egg acts as a binder to keep the Alfredo layer from being watery, a trick that makes all the difference in texture.
- Mozzarella and Parmesan (2 cups and 1 cup respectively): Shredding your own cheese from a block melts more smoothly than pre-shredded, which contains anti-caking agents that can make the top grainy.
Instructions
- Prepare the stage:
- Preheat your oven to 350°F and grease your 9x13-inch baking dish generously so nothing sticks to the bottom later. This simple step saves so much frustration when you're serving.
- Cook the pasta:
- Bring a large pot of salted water to a rolling boil and add your spaghetti, cooking it until just al dente—slightly firm to the bite. Drain it in a colander and set aside without rinsing, as the starch helps everything bind together.
- Build the meat sauce:
- Heat a large skillet over medium-high heat and add both the ground beef and sausage, breaking them up with a spoon as they brown. Once the meat is no longer pink, drain the excess fat carefully—you want flavor, not grease.
- Aromatics matter:
- Add your diced onion and minced garlic to the drained meat and let them soften for 3 to 4 minutes, stirring often until the kitchen smells like a real Italian home. This short time makes the garlic sweet and mellow instead of harsh.
- Bring it together:
- Pour in your marinara sauce, sprinkle the Italian herbs, salt, and pepper over everything, and let it simmer gently for about 5 minutes. The flavors will meld and deepen, and you'll know it's ready when the sauce tastes balanced and rich.
- Create the creamy layer:
- In a separate bowl, combine the ricotta, Alfredo sauce, sour cream, and egg, stirring until completely smooth. This mixture should look like thick, luxurious frosting—if it seems too thin, you've added too much liquid somewhere.
- Layer with intention:
- Spread half of your cooked spaghetti across the bottom of the prepared baking dish in an even layer. Pour half of the Alfredo mixture over it, then top with half of the meat sauce, followed by half of the mozzarella and half of the Parmesan—each layer should be distinct.
- Repeat the magic:
- Add the remaining spaghetti, then the rest of the Alfredo, then the remaining meat sauce, finishing with the last of both cheeses piled generously on top. This final cheese layer will turn golden and bubbly as it bakes.
- Bake covered, then uncover:
- Cover the dish tightly with foil and slide it into your preheated oven for 30 minutes, which allows everything to heat through and the flavors to meld. Remove the foil and bake for another 10 minutes until the cheese on top turns golden brown and the edges bubble.
- Rest before serving:
- Let the casserole sit for 10 minutes after coming out of the oven—this allows everything to set slightly so you can cut clean portions. Those 10 minutes feel long when you're hungry, but they make all the difference.
Save on Pinterest What moved me most about this dish was watching my elderly neighbor take a bite at a church dinner and tear up slightly, telling me it reminded her of recipes her own mother used to make decades ago. Food that bridges generations and makes people feel that kind of comfort—that's when you know you've made something that matters, not just something delicious.
Making It Your Own
The beauty of Million Dollar Spaghetti is that it's infinitely adaptable to what you have and what you love. I've swapped ground turkey for beef when I wanted something lighter, added sautéed spinach or mushrooms for earthiness, and even experimented with different marinara brands to see how it changed the final flavor. Each time felt like a new discovery rather than a failure, and that's the mark of a truly forgiving recipe.
Storage and Reheating
This casserole actually improves after a day in the refrigerator as the flavors settle and deepen, making it one of my favorite dishes to prepare ahead. Leftovers keep beautifully for up to 4 days, and reheating covered in a 325°F oven brings them back to life without drying them out—I've found that 15 to 20 minutes usually does it perfectly.
Serving Suggestions and Pairings
I always serve this with a simple green salad dressed in bright vinaigrette to cut through the richness, and garlic bread on the side for anyone who wants to soak up every last bit of sauce. The pairing feels complete and balanced, turning an ordinary weeknight into something that feels special and intentional without requiring fancy ingredients or complicated techniques.
- A crisp green salad with acidic dressing balances the richness and keeps everything feeling fresh.
- Garlic bread soaks up extra sauce and adds a satisfying crunch that contrasts beautifully with the creamy layers.
- A dry white wine or even sparkling water rounds out the meal and cleanses the palate between bites.
