Ingredients in Million Dollar Spaghetti Casserole
Here’s what makes this dish so irresistible—a blend of classic Italian flavors with a cheesy twist:
Spaghetti Noodles
The hearty base that holds all the flavors together.
Ground Beef or Italian Sausage
Provides a rich, savory depth to the sauce.
Onion and Garlic
Aromatic essentials that build a flavorful foundation.
Tomato Sauce
A robust and tangy element that ties the dish together.
Diced Tomatoes
Adds a fresh burst of acidity and texture.
Cheddar Cheese
For that sharp, melty punch of flavor.
Mozzarella Cheese
Brings a gooey, stringy texture that makes every bite comforting.
Parmesan Cheese
A sprinkle for an extra savory, umami kick.
Italian Seasoning
A blend of herbs that enhances the overall flavor profile.
Olive Oil
For sautéing and adding richness.
Salt and Pepper
To season and balance the flavors perfectly.

Instructions
Preheat Your Equipment
Preheat your oven to 375°F (190°C) to ensure the casserole bakes evenly and develops a golden top.
Cook the Pasta
Boil the spaghetti noodles in salted water until just al dente. Drain and set aside; they’ll continue to absorb flavors in the casserole.
Brown the Meat
In a large skillet, heat olive oil over medium heat. Add chopped onion and garlic, sautéing until soft and fragrant. Add the ground beef or Italian sausage and cook until browned, breaking it up into crumbles as it cooks.
Create the Sauce
Stir in the tomato sauce, diced tomatoes, and Italian seasoning. Let the mixture simmer for about 10 minutes so that the flavors meld together beautifully. Season with salt and pepper to taste.
Combine Pasta and Sauce
Gently fold the cooked spaghetti into the meat sauce until every strand is well coated. Mix in half of the cheddar and mozzarella cheeses for an extra creamy touch.
Assemble the Casserole
Transfer the pasta and meat mixture into a greased baking dish. Top evenly with the remaining cheddar, mozzarella, and a generous sprinkle of Parmesan cheese.
Bake to Perfection
Place the dish in the preheated oven and bake for 25-30 minutes, or until the cheese is melted, bubbly, and lightly golden around the edges.
Serve and Enjoy
Allow the casserole to cool slightly before serving. Dish out generous portions and enjoy the rich, comforting flavors that make this dish truly million-dollar worthy.
