Why You’ll Love This Million Dollar Spaghetti Casserole

There’s something magical about the creamy, cheesy layers mingling with a robust meat sauce and perfectly cooked pasta. This casserole is a make-ahead hero, freezer-friendly, and kid-approved. Plus, it’s a guaranteed crowd-pleaser that’s simple enough to prep on a busy weeknight and indulgent enough for a holiday table.

What Kind of Spaghetti Should I Use?

You can use classic spaghetti noodles for this recipe, but you’re not limited to them. Thin spaghetti, angel hair, or even gluten-free options all work beautifully here. What matters most is cooking the pasta al dente so it doesn’t turn mushy when baked. A firm noodle will hold up better against the rich layers of sauce and cheese.

How To Make the Million Dollar Spaghetti Casserole

Step 1: Cook the Spaghetti

Boil a pot of salted water and cook the spaghetti until just al dente. Drain and set aside. Don’t overcook—you want the pasta to hold its shape in the casserole.

Step 2: Prepare the Meat Sauce

Brown the ground beef in a skillet over medium heat. Drain the excess fat and stir in the marinara sauce. Let it simmer for a few minutes so the flavors meld.

Step 3: Make the Creamy Cheese Mixture

In a mixing bowl, combine the cream cheese, ricotta, and sour cream. Mix until smooth and creamy.

Step 4: Layer the Casserole

Start by placing half of the cooked spaghetti in a greased baking dish. Spread the cheese mixture over the pasta, then layer the remaining spaghetti on top. Pour the meat sauce over everything.

Step 5: Add the Cheese Topping

Sprinkle mozzarella and Parmesan over the top. Dot with small pieces of butter for an extra golden finish.

Step 6: Bake

Cover with foil and bake at 350°F for 30 minutes. Then uncover and bake for another 15-20 minutes until bubbly and golden on top.

This hearty casserole feeds about 8 people generously, making it perfect for large families or casual get-togethers. Let it rest for 10 minutes before slicing to help the layers set nicely.
