Cheesy Million Dollar Spaghetti Casserole: The Ultimate Family Favorite

Step 3: Make the Creamy Cheese Filling

In a mixing bowl, combine the softened cream cheese, ricotta (or cottage cheese), sour cream, garlic powder, and Italian seasoning.
Mix until smooth and creamy. This rich layer adds the signature “million dollar” taste!

Step 4: Preheat the Oven

Preheat your oven to 350°F (175°C).
Grease a 9×13-inch baking dish with butter or cooking spray.

Step 5: Assemble the Casserole

Layering is key! Here’s how to do it:

Bottom Layer – Place half of the cooked spaghetti into the baking dish. Spread it evenly.
Butter Layer – Dot the top of the spaghetti with slices of butter.
Cheese Mixture – Spread the entire cheese mixture over the buttered spaghetti layer.
Remaining Spaghetti – Add the rest of the spaghetti on top of the cheese layer.
Meat Sauce – Pour the meat sauce evenly over the top layer of spaghetti.
Cheese Topping – Sprinkle mozzarella and Parmesan cheeses generously over the top.

Step 6: Bake the Casserole

Cover the baking dish with aluminum foil and bake for 30 minutes.
After 30 minutes, remove the foil and bake for another 10–15 minutes until the cheese is bubbly and golden brown.

Step 7: Cool and Serve

Let the casserole rest for 10 minutes after baking. This helps the layers set and makes it easier to cut.
Slice into squares and serve with garlic bread and a fresh green salad.

Tips for the Best Cheesy Million Dollar Spaghetti

Customize the meat: Try a blend of ground beef and pork, or use Italian sausage for added flavor.
Make ahead: Assemble the casserole the night before, refrigerate, and bake the next day.
Freeze it: This dish freezes beautifully. Wrap tightly in foil and freeze for up to 2 months. Thaw in the fridge overnight and bake as directed.
Spice it up: Add red pepper flakes or diced jalapeños to the meat sauce for a spicy kick.
