Ingredients

  • 1 16 ounce package spaghetti
  • 2 pounds ground beef
  • 1 1/2 cups sour cream
  • 1 teaspoon garlic salt (with parsley flakes)

Instructions

  • Preheat the oven to 350. Cook the spaghetti according to the package directions, then drain.
  • While the spaghetti is cooking, add the ground beef to a large skillet. Cook, breaking into small pieces, until browned and cooked through. Drain the grease, then return the ground beef to the skillet.
  • Add the spaghetti sauce, sour cream, garlic salt, oregano, and basil to the skillet, and stir to combine. Add the noodles and 1 cup of the mozzarella cheese to the skillet, and stir to combine.
  • Pour the casserole into a 9 x 13 baking dish. Sprinkle the remaining mozzarella and the parmesan cheese over the top.
