Ingredients

(See the full ingredient list and measurements in the printable recipe card below!)

Spaghetti – Cooked al dente to hold up in the oven.
Ground beef – Or swap with Italian sausage or ground turkey.
Marinara or pasta sauce – Use your favorite brand or homemade.
Cream cheese – Room temp so it mixes easily.
Sour cream – Adds a tangy creaminess.
Cottage cheese or ricotta – Either works great in the creamy filling.
Shredded mozzarella – For that stretchy, cheesy topping.
Parmesan cheese – Adds saltiness and umami.
Onion – Diced and sautéed with the meat.
Garlic – Because everything’s better with garlic.
Butter – To toss with the pasta for richness.
Italian seasoning – Optional, but adds great flavor.
Salt and pepper – To taste.

Instructions

1. Preheat and prep:
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch casserole dish.

2. Boil the spaghetti:
Cook the pasta in well-salted water until just al dente. Drain and toss with butter to prevent sticking.

3. Cook the meat sauce:
In a large skillet, sauté onions until translucent. Add the ground beef and cook until browned. Drain any excess fat. Stir in garlic and cook for 1 minute. Pour in the marinara sauce and simmer for 5–10 minutes. Season with salt, pepper, and Italian seasoning.

4. Make the creamy cheese layer:
In a bowl, combine cream cheese, sour cream, and cottage cheese or ricotta. Mix until smooth and creamy.

5. Layer it up:
In your baking dish, layer half the spaghetti. Spread the cheese mixture on top, then layer the remaining spaghetti. Pour the meat sauce over the top, spreading evenly.

6. Add the cheese:
Top with shredded mozzarella and grated Parmesan.

7. Bake:
Cover with foil and bake for 30 minutes. Uncover and bake another 10–15 minutes, or until bubbly and golden.

8. Let it rest:
Allow the casserole to sit for 10 minutes before slicing. This helps it set and makes serving easier.
