Step-by-Step Instructions
Cook the pasta:
Bring a large pot of salted water to a boil, cook spaghetti until just al dente, then drain. A slightly firm texture is key because it will finish cooking in the oven.Prepare the meat sauce:
In a large skillet over medium heat, brown the ground beef or sausage until fully cooked.
Add onion and cook until softened, about 3–4 minutes.
Stir in garlic, cook for 30 seconds until fragrant.
Pour in marinara sauce, add basil, oregano, and red pepper flakes if using. Season with salt and pepper. Let simmer for 10 minutes.
Make the creamy cheese mixture:
In a bowl, combine cream cheese, ricotta (or cottage cheese), and sour cream until smooth. This mixture is the “secret ingredient” that makes the dish taste so indulgent.Assemble the casserole:
Preheat oven to 350°F (175°C).
Spread a thin layer of meat sauce in the bottom of a greased 9x13 baking dish.
Layer half the cooked spaghetti on top.
Spread all of the creamy cheese mixture over the pasta.
Add half of the remaining meat sauce.
Repeat with the rest of the spaghetti, then the rest of the meat sauce.
Top generously with mozzarella and Parmesan cheese.
Bake to perfection:
Cover with foil and bake for 20 minutes. Remove foil and bake an additional 10–15 minutes, until cheese is melted and golden brown.Serve and enjoy:
Let the casserole rest for 5 minutes before slicing. Garnish with fresh parsley for a pop of color and freshness.
Tips for Success
Don’t overcook the pasta: It will soften in the oven.
Let it rest: Cutting into it too soon can cause the layers to collapse.
Customize the filling: Add sautéed spinach, mushrooms, or roasted peppers for extra flavor and nutrients.
