This Viral TikTok Alfredo Spaghetti Casserole is a rich, creamy, and irresistibly cheesy baked pasta dish. Featuring layers of al dente spaghetti mixed with creamy Alfredo sauce and Parmesan cheese, topped with a savory ground beef marinara sauce and melted mozzarella, it’s perfect for busy weeknights or any occasion when you crave comforting Italian flavors.

  • Total Time: 1 hour 10 minutes
  • Yield: 8 servings

Ingredients

For the Pasta Layer:

  • 1 pound spaghetti
  • 2 jars (15 ounces each) Alfredo sauce
  • ½ cup butter, melted
  • 1 cup grated Parmesan cheese

For the Meat Sauce:

  • 2 pounds ground beef
  • 1 onion, diced
  • 1 tablespoon minced garlic
  • 2 jars (24 ounces each) marinara sauce
  • 2 teaspoons Italian seasoning
  • 1 teaspoon salt
  • ½ teaspoon black pepper

Topping:

  • 2 cups shredded mozzarella cheese
  • Chopped fresh parsley (optional)

Instructions

  1. Preheat Oven and Prepare Dish: Preheat your oven to 350°F (175°C) and spray a 9×13-inch baking dish with cooking spray to prevent sticking.
  2. Cook Spaghetti: Boil the spaghetti according to package instructions until al dente. Drain thoroughly to remove excess water.
  3. Mix Pasta Layer: In the prepared baking dish, combine the cooked spaghetti, Alfredo sauce, melted butter, and grated Parmesan cheese. Stir well to fully incorporate all ingredients and spread the mixture evenly across the dish.
  4. Cook Meat Sauce: In a large skillet over medium-high heat, cook ground beef and diced onion together until the beef is browned and onions are softened, about 6 to 7 minutes. Add minced garlic and cook for an additional minute to release its aroma.
  5. Add Sauce and Seasonings: Stir in the marinara sauce, Italian seasoning, salt, and black pepper into the beef mixture. Let it simmer for 5 minutes to blend the flavors and thicken slightly.
  6. Layer Meat Sauce: Pour the prepared meat sauce evenly over the Alfredo spaghetti layer in the baking dish, spreading it out smoothly.
  7. Add Cheese Topping: Sprinkle the shredded mozzarella cheese uniformly over the top of the casserole.
  8. Bake: Place the casserole uncovered in the preheated oven and bake for 25 to 30 minutes, until the cheese is melted, bubbly, and slightly golden.
  9. Rest and Serve: Let the casserole stand for 10 minutes after removing from the oven to set. Garnish with chopped fresh parsley if desired before serving. Enjoy your comforting Alfredo spaghetti casserole!

Notes

  • Make sure to cook the spaghetti just until al dente to avoid overcooking during baking.
  • You can substitute ground beef with ground turkey or Italian sausage for variations.
  • For extra cheesiness, add a layer of shredded mozzarella between the pasta and meat sauce.
  • Leftovers keep well in the refrigerator for up to 3 days and reheat nicely in the oven or microwave.
