Ingredients

  • 1 lb spaghetti
  • 1 lb ground beef
  • 1 lb ground pork
  • 1 onion
  • 1 green bell pepper
  • 5 cloves garlic
  • 28 oz marinara sauce
  • 1/2 cup butter
  • 2 cup heavy cream
  • 1 cup Parmesan cheese
  • 1 tsp Italian seasoning
  • 1 tsp salt
  • 1 tsp pepper
  • 8 oz mozzarella cheese

Instructions

  1. 1
    Preheat the oven to 350°F. Coat a 9x13 casserole dish with nonstick spray.
  2. 2
    Cook the spaghetti al dente, according to the package directions. Drain and set aside.
  3. 3
    Cook the beef, pork, onion, bell pepper, and half the garlic in a large skillet over medium-high heat, breaking up the meat into tiny crumbles, until the meat is no longer pink and the vegetables are tender. Drain off the grease, then stir in the marinara sauce until incorporated. Set the sauce to the side.
  4. 4
    Melt the butter in a large pot over medium-high heat. Add in the remaining garlic and cook until fragrant, about 20 seconds. Stir in the heavy cream, parmesan, Italian seasoning, salt, and pepper. Cook until the sauce has started to thicken.
  5. 5
    Add in the cooked spaghetti and toss until the noodles are fully coated, then dump it into the prepared casserole dish in an even layer.
  6. 6
    Pour the meat sauce over the Alfredo spaghetti and top with the mozzarella cheese.
  7. 7
    Bake, uncovered, for about 20 minutes or until the cheese is bubbly.
  8. 8
    Remove the casserole from the oven and let it rest for a few minutes before serving.
  9. 9
    Serve hot, garnished with additional parmesan cheese and parsley if desired.
