Ingredients
  

  • 1 pound spaghetti
  • 1 pound lean ground beef
  • 24 oz marinara sauce
  • 1/2 cup unsalted butter
  • 8 oz cream cheese, softened
  • 1 cup sour cream
  • 1/4 cup onion, finely minced
  • 2 cups cheddar cheese, freshly shredded
  • 1 teaspoon garlic powder
  • 1 tablespoon Italian seasoning

Instructions
 

  • Preheat your oven to 350°F (175°C).
  • Cook the spaghetti according to package instructions until al dente, then drain and set aside.
  • In a large skillet, brown the ground beef over medium heat until fully cooked; drain excess fat if necessary.
  • Stir the marinara sauce into the cooked ground beef and simmer for 5 minutes.
  • In a medium bowl, combine the softened cream cheese, sour cream, minced onion, garlic powder, and Italian seasoning until smooth.
  • Place the cooked spaghetti in a 9x13 inch baking dish and toss with the melted butter.
  • Spread the cream cheese mixture evenly over the top of the buttered noodles.
  • Pour the meat sauce over the cream cheese layer, spreading it to the edges.
  • Top the entire casserole with the shredded cheddar cheese.
  • Bake for 35 minutes or until the cheese is melted and bubbling.

Notes

For the best melting results, shred your cheddar cheese directly from a block rather than using pre-shredded cheese. You can substitute the cheddar with mozzarella if preferred. Store leftovers in an airtight container for up to 3 days.
