Baked Cream Cheese Spaghetti Casserole

Step 2: Prepare the Meat Sauce

In a large skillet over medium heat, add the olive oil. Sauté the chopped onion for 3–4 minutes until soft and translucent. Add the minced garlic and cook for another 30 seconds until fragrant.

Add the ground beef (or turkey), breaking it apart with a spatula. Cook until browned and fully cooked, about 6–8 minutes. Season with salt, pepper, and Italian seasoning. Drain any excess fat if necessary.

Stir in the marinara sauce and simmer for 5 minutes, allowing the flavors to meld.

Step 3: Make the Creamy Base

In a separate bowl, combine the softened cream cheese with ½ cup of the mozzarella. Mix until smooth. This will create a creamy layer that binds the spaghetti and meat sauce together.

Step 4: Assemble the Casserole

In a large mixing bowl, combine the cooked spaghetti with the meat sauce. Stir until the pasta is evenly coated. Then, fold in the cream cheese mixture until creamy and smooth.

Transfer the spaghetti mixture into a greased 9×13-inch baking dish. Spread evenly with a spatula. Sprinkle the remaining mozzarella and Parmesan cheese on top for a golden, melty finish.

Step 5: Bake to Perfection

Place the casserole in the preheated oven and bake for 20–25 minutes until the cheese is bubbly and slightly golden on top. For a crispier top, you can broil for an additional 2–3 minutes—just watch closely to avoid burning.

Step 6: Serve and Garnish

Remove the casserole from the oven and let it sit for 5 minutes before serving. This allows the layers to set slightly, making it easier to cut. Garnish with freshly chopped parsley or basil for a pop of color and fresh flavor.

Tips for the Perfect Casserole:

1. Use full-fat cream cheese for the creamiest texture.
2. Add vegetables like bell peppers, mushrooms, or spinach to make it more nutritious.
3. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave.
4. For a richer flavor, stir in a splash of heavy cream with the cream cheese mixture.
