A quick and comforting baked spaghetti casserole with a creamy sauce made from cream cheese and sour cream, perfect for family dinners and busy weeknights.

Ingredients

Scale
  • 12 ounces spaghetti, cooked al dente
  • 1 pound ground beef, browned and drained
  • 8 ounces cream cheese, softened
  • 1 cup sour cream (full-fat preferred)
  • 2 cups shredded sharp cheddar cheese
  • ½ cup grated Parmesan cheese
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 1 cup tomato sauce
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon Italian seasoning
  • Salt and pepper to taste
  • 1 tablespoon olive oil

Instructions

  1. Bring a large pot of salted water to a boil. Add 12 ounces of spaghetti and cook until al dente, about 8-9 minutes. Drain and set aside. Save a cup of pasta water if needed to loosen sauce.
  2. Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add 1 pound ground beef and cook, breaking it up with a spoon, until no longer pink, about 6-8 minutes. Drain excess fat.
  3. Add 1 finely chopped small onion and 2 minced garlic cloves to the skillet. Cook until softened and fragrant, about 3-4 minutes.
  4. Stir in 1 cup tomato sauce, 1 tablespoon Worcestershire sauce, 1 teaspoon Italian seasoning, and salt & pepper to taste. Let simmer gently for 5 minutes.
  5. In a large mixing bowl, combine 8 ounces softened cream cheese and 1 cup sour cream. Mix until smooth and creamy.
  6. Add the cooked spaghetti and beef mixture into the creamy sauce bowl. Gently toss until pasta is well coated. Add reserved pasta water if mixture is too thick.
  7. Pour the pasta mixture into a greased 9×13-inch baking dish. Sprinkle 2 cups shredded cheddar cheese evenly over the top, followed by ½ cup grated Parmesan.
  8. Preheat oven to 350°F. Bake uncovered for 25-30 minutes until cheese is bubbly and golden brown.
  9. Let the casserole rest for 5-10 minutes before serving.

Notes

Do not overcook spaghetti; it should be al dente as it will soften further in the oven. Browning the ground beef thoroughly adds flavor. Soften cream cheese properly to avoid lumps. Let casserole rest before serving to improve texture and flavor. If casserole seems dry after baking, drizzle olive oil or add a spoonful of sour cream on serving.
