Ingredients
  

  • 1 pound spaghetti
  • 1 pound ground beef or Italian sausage
  • 1 medium onion, chopped
  • 2 cloves garlic, minced
  • 8 ounces cream cheese, softened
  • 24 ounces tomato sauce
  • 14.5 ounces diced tomatoes, undrained
  • 2 teaspoons Italian seasoning
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 cups mozzarella cheese, shredded
  • 1/2 cup Parmesan cheese, grated

Equipment

  • large pot
  • colander
  • large skillet
  • 9x13-inch baking dish
  • mixing bowl
  • measuring cups and spoons
  • wooden spoon or spatula

Method
 

  1. Preheat oven to 350°F (175°C).
  2. Cook the spaghetti according to package directions. Drain well and set aside.
  3. In a large skillet, brown the ground beef (or sausage) over medium heat. Drain off any excess grease.
  4. Add the chopped onion and cook until softened, about 5 minutes. Then, add the minced garlic and cook for another minute until fragrant.
  5. Stir in the tomato sauce, diced tomatoes, Italian seasoning, salt, and pepper. Bring to a simmer and cook for 10-15 minutes, allowing the flavors to meld together.
  6. Remove the skillet from the heat and stir in the softened cream cheese until it's completely melted and smooth.
  7. In a large bowl, combine the cooked spaghetti and the cream cheese sauce. Mix well until everything is evenly coated.
  8. Pour the spaghetti mixture into a greased 9x13 inch baking dish.
  9. Sprinkle with mozzarella cheese and Parmesan cheese.
  10. Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly and the casserole is heated through. The top should be lightly golden brown.
  11. Let it rest for a few minutes before serving.

Notes

Don't overcook the spaghetti; aim for al dente. Soften the cream cheese for easy mixing. Add sautéed mushrooms, bell peppers, or zucchini for added vegetables. Spice it up with a pinch of red pepper flakes. Assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours before baking. Freeze for up to 3 months.
