Main Ingredients

  • 12 oz dried spaghetti
  • 4 cups chopped cooked chicken
  • 1 16 oz sour cream

  • 1 6 oz can French's French Fried Onions

Instructions
 

  • Preheat your oven to 350°F (175°C). Lightly spray a 9x13-inch baking pan with cooking spray to prevent sticking.

  • Gently stir in the cooked spaghetti until it is evenly coated with the mixture.
  • Pour the spaghetti mixture into the prepared baking pan, spreading it out evenly.
  • Sprinkle the remaining shredded cheese and the rest of the French Fried Onions on top of the pasta mixture.
  • Bake uncovered in the preheated oven for 40 to 50 minutes, or until the top is golden and bubbly.

Notes

For added flavor, consider seasoning the mixture with salt, pepper, or your favorite herbs. You can substitute the Monterey Jack cheese with cheddar or mozzarella for a different taste.
