Make this comforting, cheesy Monterey Chicken Spaghetti Casserole for an easy weeknight dinner. It combines tender chicken and spaghetti in a rich sauce, topped with crispy onions for a satisfying family meal.

Ingredients

Scale
  • 12 ounces spaghetti noodles
  • 2 cups cooked, shredded chicken breast
  • 1 can (10.5 ounces) cream of chicken soup
  • 1 cup sour cream
  • 1 cup frozen spinach, thawed and squeezed dry
  • 2 cups shredded Monterey Jack cheese, divided
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • Salt and pepper to taste
  • 1 cup French fried onions
  • 2 tablespoons butter, melted (optional, for topping)

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
  2. Cook the spaghetti according to package directions until al dente. Drain the pasta well and set it aside.
  3. In a large bowl, combine the shredded chicken, cream of chicken soup, sour cream, drained spinach, 1 teaspoon garlic powder, 1/2 teaspoon onion powder, salt, and pepper. Mix these ingredients until they are fully combined.
  4. Stir in 1 1/2 cups of the shredded Monterey Jack cheese and the drained spaghetti into the chicken mixture until everything is evenly coated.
  5. Transfer the entire mixture to your prepared baking dish and spread it into an even layer.
  6. Sprinkle the remaining 1/2 cup of Monterey Jack cheese over the top of the pasta mixture.
  7. Scatter the French fried onions evenly over the cheese layer. If you want extra crispness, drizzle the melted butter over the onions.
  8. Bake for 20 to 25 minutes, or until the casserole is hot throughout and the topping is golden brown.
  9. Let the casserole rest for 5 minutes before you serve it.

Notes

  • You can use leftover rotisserie chicken to save time on cooking the chicken breast.
  • For a slight Tex-Mex flavor, stir in 1/4 cup of drained Rotel diced tomatoes with green chilies when mixing the sauce.
  • This dish freezes well; assemble the casserole completely, cover tightly, and freeze before baking. Thaw overnight in the refrigerator before baking as directed.
