Description

This creamy, cheesy Monterey Chicken Spaghetti is a comforting casserole packed with shredded chicken, tender spaghetti, spinach, and gooey Monterey Jack cheese. Topped with crispy fried onions, it’s the ultimate weeknight dinner or potluck crowd-pleaser!


Ingredients

Scale
  • 12 oz spaghetti

  • 2 chicken breasts, cooked and chopped

  • 1 cup Monterey Jack cheese, shredded

  • ½ cup Parmesan cheese, shredded

  • 1 cup sour cream

  • 1 egg, beaten

  • 1 (10 oz) package chopped spinach, thawed and squeezed dry

  • 3 cloves garlic, minced (or 1 tablespoon garlic powder)

  • 2 (10 oz) cans cream of chicken soup

  • 1 teaspoon onion powder

  • 6 oz French fried onions, divided (about 1 can)


Instructions

  • Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish.

  • Cook pasta: Boil spaghetti in salted water according to package directions. Drain and set aside.

  • Prepare the filling: In a large mixing bowl, combine cooked chicken, Monterey Jack cheese, Parmesan cheese, sour cream, beaten egg, thawed spinach, garlic, cream of chicken soup, and onion powder. Mix well.

  • Combine pasta: Stir the cooked spaghetti into the chicken mixture until evenly coated.

  • Assemble: Pour the mixture into the prepared baking dish. Sprinkle half of the French fried onions over the top.

  • Bake: Bake uncovered for 30–35 minutes, until hot and bubbly.

  • Top and finish: Add the remaining French fried onions during the last 5 minutes of baking for an extra crispy topping.

 

  • Serve hot, optionally garnished with fresh parsley.

Notes

Use rotisserie chicken for a quick prep shortcut.

Can be made ahead and refrigerated—just add 5–10 minutes to the baking time.

Add a dash of cayenne or hot sauce for a spicy twist.
