Ingredients

  • 12 oz thin spaghetti cooked al dente, drained, and transferred to the baking dish immediately
  • 1 cup sour cream
  • 4 oz cream cheese
  • 2 green onions thinly sliced and chopped
  • 1 egg
  • 2 tbsp olive oil
  • 1 lb lean ground beef
  • 1/2 yellow onion diced
  • 4 cloves garlic minced
  • 1/2 tsp garlic powder
  • 1/2 tsp kosher salt
  • 1/4 tsp ground black pepper
  • 1 (14 oz) jar spaghetti sauce*
  • 1 cup monterey jack cheese grated
  • 1 cup mozzarella cheese grated

For Optional Garnish

  • freshly chopped parsley
  • parmesan cheese grated

Instructions

  • Preheat oven to 350 degrees. Butter or spray a 9x13-inch baking dish, add cooked noodles, set aside.
  • In a medium mixing bowl, whisk together sour cream, cream cheese, green onions and egg, set aside.
  • In a large skillet set over medium heat, add the oil. Once the oil is hot, add the ground beef and cook until browned, breaking it apart as you go. Add the onion and garlic, cook for 3-4 minutes. Stir in the garlic powder, salt, and black pepper. Cook for 1 minute, then remove from the heat.
  • Spread sour cream mixture over the cooled noodles. Spread beef in an even layer over top, then sauce, then cheeses. Cover dish with aluminum foil and bake for 20 minutes. Remove the foil and continue baking for an additional 10 minutes or until the cheese is melty and golden brown in spots.
  • Remove from the oven and allow to cool for 10 minutes before serving. Garnish with freshly chopped parsley and grated parmesan, if desired.

Notes

* Use your favorite brand of sauce, or your own homemade sauce. If you prefer a saucier casserole, add 18 oz. of sauce.
