Ingredients
The magic of this Million Dollar Spaghetti Casserole Recipe lies in its simple, yet thoughtfully selected ingredients. Each element plays a role in creating the creamy, cheesy, and comforting character of this dish.

1 lb ground beef or Italian sausage (optional): Adds savory protein and depth.
1 jar (24 oz) marinara sauce: A rich, flavorful base with Italian herbs.
8 oz cream cheese, softened: Ensures a smooth, velvety texture.
1/2 cup sour cream: Lightens the sauce while adding tangy richness.
1/2 cup ricotta cheese: Provides subtle creaminess without overpowering flavors.
2 cups shredded mozzarella cheese: Perfect gooey melt for that irresistible top layer.
1/2 cup grated Parmesan cheese: Salty, nutty flavor enhances the overall dish.
1 teaspoon garlic powder & 1 teaspoon onion powder: Adds warmth and aromatic undertones.
1 teaspoon dried oregano: Classic Italian herb flavor.
Salt and pepper to taste: Essential for seasoning and flavor balance.
Fresh parsley (optional, for garnish): Adds brightness and visual appeal.
Pro Tip: For extra flavor, brown the meat with a pinch of smoked paprika or red pepper flakes. Fresh herbs like basil or thyme can also elevate the taste.
How to Make Million Dollar Spaghetti Casserole
Step 1: Cook the Spaghetti
Boil spaghetti in salted water until al dente. Drain and set aside. Slightly undercooked pasta is ideal because it will finish cooking in the oven, absorbing all the creamy, cheesy goodness.
Step 2: Prepare the Meat (Optional)
In a large skillet, brown the ground beef or Italian sausage over medium heat. Season with garlic powder, onion powder, oregano, salt, and pepper. Drain excess fat if necessary.
Step 3: Mix the Creamy Base
In a large bowl, combine cream cheese, sour cream, and ricotta cheese. Stir until smooth. Gradually mix in 1 cup of mozzarella and Parmesan cheese.
Step 4: Combine Everything
Add the cooked spaghetti and meat to the creamy cheese mixture. Pour in the marinara sauce and stir gently until the pasta is evenly coated.
Step 5: Assemble the Casserole
Transfer the mixture into a greased 9×13-inch baking dish. Sprinkle remaining mozzarella and Parmesan cheese evenly over the top.
Step 6: Bake to Perfection
Preheat oven to 375°F (190°C) and bake for 25–30 minutes, or until the top is golden and bubbly. Optional: broil for 2–3 minutes for a perfectly crispy cheese crust.
Step 7: Garnish & Serve
Top with chopped parsley before serving for a pop of color and fresh flavor.
