Ingredients

1 pound spaghetti
1.5 pounds lean ground beef (80/20 recommended)
0.5 pound mild or hot Italian sausage (casings removed, optional)
1 tablespoon olive oil
1 medium yellow onion, chopped
4-6 cloves garlic, minced
2 (24-ounce) jars marinara sauce (your favorite brand)
1 (15-ounce) can crushed tomatoes
1 tablespoon Italian seasoning
1 teaspoon dried basil
0.5 teaspoon dried oregano
0.25 teaspoon red pepper flakes (optional, for a little heat)
1 teaspoon salt, plus more for pasta water
0.5 teaspoon black pepper
1 (15-ounce) container whole milk ricotta cheese
4 ounces cream cheese, softened
0.25 cup sour cream
1 large egg
0.5 cup grated Parmesan cheese, divided
3 cups shredded mozzarella cheese, divided
0.25 cup fresh parsley, chopped (for garnish)

Instructions

Cook the Spaghetti: Bring a large pot of salted water to a rolling boil. Add the spaghetti and cook according to package directions until al dente (firm to the bite). It’s crucial not to overcook, as it will continue to cook in the oven. Drain well and toss with a drizzle of olive oil to prevent sticking. Set aside.
Prepare the Meat Sauce: In a large skillet or Dutch oven, heat 1 tablespoon of olive oil over medium-high heat. Add the ground beef and Italian sausage (if using) and cook, breaking it apart with a spoon, until browned. Drain off any excess fat.
Add the chopped onion to the skillet and cook until softened, about 5-7 minutes. Stir in the minced garlic and cook for another minute until fragrant.
Pour in the marinara sauce and crushed tomatoes. Stir in the Italian seasoning, dried basil, dried oregano, red pepper flakes (if using), 1 teaspoon salt, and 0.5 teaspoon black pepper. Bring the sauce to a simmer, then reduce the heat to low, cover, and let it simmer for at least 15-20 minutes, or up to an hour, for the flavors to meld. Stir occasionally.
Make the Creamy Cheese Layer: While the sauce simmers, in a medium bowl, combine the ricotta cheese, softened cream cheese, sour cream, and egg. Add 0.25 cup of the grated Parmesan cheese and 1 cup of the shredded mozzarella cheese. Mix well until everything is thoroughly combined and smooth.
Assemble the Casserole: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Spread half of the cooked spaghetti evenly across the bottom of the prepared baking dish.
Carefully spread the entire creamy cheese mixture over the first layer of spaghetti.
Top with the remaining cooked spaghetti, spreading it out as evenly as possible.
Pour the entire meat sauce mixture over the spaghetti, ensuring it’s distributed evenly.
Finally, sprinkle the remaining 2 cups of shredded mozzarella cheese and 0.25 cup of grated Parmesan cheese over the top of the casserole.
Bake to Perfection: Cover the baking dish tightly with aluminum foil. Bake for 20-25 minutes.
Remove the foil and continue to bake for another 10-15 minutes, or until the cheese is melted, bubbly, and golden brown on top. If you like a darker, crispier top, you can briefly place it under the broiler for 1-2 minutes (watch carefully to prevent burning).
Rest and Serve: This is a crucial step! Let the Million Dollar Spaghetti Casserole rest for 10-15 minutes after removing it from the oven. This allows the layers to set and prevents it from falling apart when you serve it.
Garnish with fresh chopped parsley before serving.

Cooking Tips and Variations

To truly elevate your Million Dollar Spaghetti Casserole from great to unforgettable, consider these expert tips and exciting variations. For a deeper, richer meat sauce, deglaze the pan after browning the meat with a splash of dry red wine, like a Merlot or Cabernet Sauvignon, scraping up all those flavorful bits from the bottom before adding the marinara. This simple step adds an incredible depth of flavor. Don’t be shy with fresh herbs; while dried herbs are convenient, finishing the dish with a generous sprinkle of fresh basil or parsley after baking brightens the entire flavor profile and adds a pop of color. Another secret weapon for an umami boost in your meat sauce is to add a discarded Parmesan rind while it simmers; just remember to remove it before assembling the casserole. If your tomato sauce tastes a little too acidic, a pinch of sugar (about half a teaspoon) can work wonders to balance the flavors without making it sweet.

Texture is key in this dish. Always cook your spaghetti only to al dente; remember it will continue to cook and soften in the oven, and nobody wants mushy pasta. Thoroughly draining the cooked meat is essential to prevent a greasy casserole, ensuring the sauce remains rich and savory. When it comes to the creamy cheese layer, using whole milk ricotta will give you a much richer and more luxurious texture compared to part-skim. And for that perfectly smooth, lump-free cheese layer, make sure your cream cheese is softened to room temperature before mixing it in.

Feeling adventurous? This recipe is incredibly versatile. For a lighter or different protein option, swap the ground beef and sausage for ground turkey or chicken. For a hearty vegetarian version, use lentils, finely chopped mushrooms, or a combination of plant-based crumbles in place of the meat. Spice lovers can kick it up a notch by adding extra red pepper flakes to the meat sauce, or even a dash of hot sauce. Don’t hesitate to sneak in some extra veggies; sautéed bell peppers, mushrooms, zucchini, or even a handful of fresh spinach can be incorporated into the meat sauce for added nutrition and flavor. You can also experiment with different cheeses; a layer of sliced provolone under the top mozzarella can add an extra layer of sharp, melty goodness.

Storage and Reheating

This Million Dollar Spaghetti Casserole is not only delicious fresh from the oven but also makes for fantastic leftovers, and it’s incredibly freezer-friendly. To store leftovers, allow the casserole to cool completely to room temperature. Then, transfer individual portions or the entire remaining casserole to an airtight container. It will keep beautifully in the refrigerator for up to 3-4 days. For reheating individual portions, the microwave is your friend: simply place a serving on a microwave-safe plate, cover loosely, and heat for 2-3 minutes, or until warmed through. For larger portions or the entire casserole, preheat your oven to 350°F (175°C), cover the dish with foil to prevent drying out, and bake for 20-30 minutes, or until heated through. You can remove the foil for the last 5-10 minutes if you want to crisp up the top cheese again.

Freezing this casserole is a brilliant way to prepare make-ahead meals. You have two options: freeze it unbaked or baked. If freezing unbaked, assemble the casserole according to the instructions, but do not bake. Cover the dish tightly with a double layer of aluminum foil, ensuring no air can get in. Label with the date and freeze for up to 3 months. When ready to bake, thaw overnight in the refrigerator, then bake as directed, adding an extra 10-15 minutes to the covered baking time. If freezing baked, allow the casserole to cool completely after baking. Cut it into individual portions or leave it whole. Wrap tightly in a double layer of plastic wrap and then foil to prevent freezer burn. Freeze for up to 3 months. To reheat from frozen, thaw overnight in the refrigerator, then follow the oven reheating instructions above. Alternatively, you can reheat directly from frozen in the oven (covered with foil) at 350°F (175°C) for a longer period, typically 45-60 minutes, or until heated through. Just be sure to check the internal temperature to ensure it’s piping hot.

Frequently Asked Questions

Can I prepare Million Dollar Spaghetti Casserole ahead of time?

Absolutely! This casserole is an excellent make-ahead meal. You can assemble the entire dish up to 24 hours in advance, cover it tightly with plastic wrap or foil, and refrigerate it. When you’re ready to bake, simply remove it from the fridge about 30 minutes before baking to allow it to come closer to room temperature, and then bake as directed, adding an extra 10-15 minutes to the covered baking time since it’s starting cold.

What can I serve with Million Dollar Spaghetti Casserole?

This rich and hearty casserole pairs wonderfully with simple, fresh sides. A crisp green salad with a light vinaigrette is perfect for cutting through the richness. Garlic bread or crusty Italian bread is a must for soaking up any extra sauce. Steamed or roasted vegetables like green beans, broccoli, or asparagus also make great accompaniments, adding a touch of freshness and balance to the meal.

My casserole is a bit watery. What went wrong?

A watery casserole can happen for a few reasons. The most common culprits are not draining enough fat from the ground meat, or not properly draining the spaghetti after cooking. Ensure you drain all excess grease from the meat before adding the sauce. Also, make sure your spaghetti is well-drained and not dripping wet before layering. Using whole milk ricotta cheese can also help, as it typically has less water content than part-skim. Allowing the casserole to rest for 10-15 minutes after baking is also crucial, as it allows the liquids to reabsorb and the layers to set.

Can I make this vegetarian?

Yes, easily! To make a vegetarian version, simply omit the ground beef and Italian sausage. You can replace them with a combination of finely diced mushrooms (sautéed until most of their moisture has evaporated), cooked brown or green lentils, or your favorite plant-based ground crumbles. Sauté these vegetarian alternatives with the onion and garlic, then proceed with the recipe as directed for the sauce.
