Step-by-Step Instructions: How to Prepare the Baked Cream Cheese Spaghetti Casserole

1. Preheat the Oven

Set your oven to 350°F (175°C) and allow it to fully preheat. This temperature allows the casserole to bake evenly and ensures the cheese melts perfectly without burning.

2. Cook the Spaghetti

Fill a large pot with water and add a generous pinch of salt (this seasons the pasta). Bring it to a rolling boil over high heat. Add 12 oz of spaghetti and cook according to the package directions, usually about 8-10 minutes, until the pasta is al dente—meaning tender but still slightly firm to the bite.

Drain the cooked spaghetti in a colander and set it aside. Don’t rinse the pasta, as the starch helps the sauce cling better.

3. Prepare the Meat Sauce

Heat a large skillet over medium heat and add the 1 lb of lean ground beef. Use a wooden spoon or spatula to break up the meat as it cooks. Brown the beef thoroughly, about 6-8 minutes, stirring occasionally.

Once the beef is cooked, carefully drain excess fat from the pan to keep the dish from becoming greasy.

Add the minced garlic to the skillet and sauté for about 1 minute until fragrant.

Pour in the 28 oz jar of spaghetti sauce and stir well to combine. Season with salt and pepper to taste. Let the sauce simmer gently for about 5 minutes to allow the flavors to meld.

4. Combine Cream Cheese with Spaghetti

While the sauce simmers, place the softened cream cheese in a large mixing bowl. Add the hot cooked spaghetti on top.

Using tongs or two large forks, gently toss and mix the spaghetti with the cream cheese until the pasta is evenly coated and creamy. The heat from the pasta will melt the cream cheese, creating a luscious, rich coating around every strand.

5. Assemble the Casserole

Lightly grease a 9×13-inch baking dish with cooking spray or a little oil.

Transfer the cream cheese-coated spaghetti to the baking dish and spread it out evenly.

Pour the prepared meat sauce evenly over the spaghetti layer.

If you’re using shredded mozzarella cheese, sprinkle it generously over the top to create a melty, golden crust.

6. Bake the Casserole

Place the baking dish in the preheated oven and bake for 30 minutes, or until the cheese on top is melted and bubbling, and the casserole is heated through.

If you prefer extra browning, you can broil the casserole for 1-2 minutes at the end — just watch it carefully to avoid burning.

7. Rest and Serve

Once baked, remove the casserole from the oven and let it rest for 5 minutes before serving. This resting period allows the casserole to set slightly, making it easier to cut and serve.

Serve warm and enjoy the creamy, cheesy goodness!

 Pro Tips for the Best Baked Cream Cheese Spaghetti Casserole

  1. Use Quality Ingredients: Fresh garlic and good-quality spaghetti sauce elevate the flavor tremendously.

  2. Don’t Overcook Pasta: Cook spaghetti al dente as it will continue to cook in the oven, preventing mushy noodles.

  3. Make It Your Own: Add sautéed vegetables like mushrooms, bell peppers, or spinach for extra nutrition and flavor.

  4. Spice It Up: Sprinkle red pepper flakes or add diced jalapeños into the sauce for a spicy kick.

  5. Make Ahead: You can assemble this casserole a few hours ahead and refrigerate it covered. Bake it just before serving.

  6. Leftovers: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F to keep the crust crisp.
