Make this easy Monterey Chicken Spaghetti Casserole for a comforting, cheesy weeknight dinner. This recipe combines tender chicken, spaghetti, and Monterey Jack cheese into a satisfying bake.

Ingredients

Scale
  • 1 pound spaghetti, cooked and drained
  • 2 cups cooked, shredded chicken
  • 1 (10.5 ounce) can cream of chicken soup
  • 1 cup sour cream
  • 1 cup milk
  • 1 teaspoon garlic powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 (10 ounce) package frozen chopped spinach, thawed and squeezed dry
  • 2 cups shredded Monterey Jack cheese, divided
  • 1/2 cup French fried onions (for topping)

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. In a large bowl, whisk together the cream of chicken soup, sour cream, milk, garlic powder, salt, and pepper until smooth. This creates your savory sauce base.
  3. Add the cooked spaghetti, shredded chicken, and drained spinach to the sauce mixture. Stir gently until all ingredients are evenly coated.
  4. Fold in 1 1/2 cups of the Monterey Jack cheese into the pasta mixture.
  5. Spread the mixture evenly into the prepared baking dish.
  6. Sprinkle the remaining 1/2 cup of Monterey Jack cheese over the top of the casserole.
  7. Bake for 20 minutes, or until the casserole is heated through and the cheese is melted.
  8. Remove the dish from the oven and sprinkle the French fried onions evenly over the top.
  9. Return the casserole to the oven and bake for an additional 5 minutes, or until the onions are golden brown and crispy.
  10. Let the Monterey Chicken Spaghetti cool for 5 minutes before you serve it.

Notes

  • You can substitute rotisserie chicken for the cooked chicken to save preparation time on a busy weeknight.
  • For a richer flavor, use half Monterey Jack cheese and half sharp cheddar cheese in the mix.
  • This casserole freezes well; assemble it completely, cover tightly, and freeze before baking. Thaw overnight in the refrigerator before baking as directed, adding 10-15 minutes to the initial bake time.
