Description

Monterey chicken spaghetti casserole combines creamy textures with bold southwestern flavors. Hearty ingredients and simple preparation make this dish a comforting meal for families craving rich, cheesy goodness you’ll devour with delight.


Ingredients

Scale
  • 4 cups rotisserie chicken (finely chopped)
  • 12 oz premium pasta noodles (spaghetti, linguini, or fettucine)
  • 4 cups fresh baby spinach (finely chopped)
  • 2 cups sour cream
  • 2 cans cream of chicken soup
  • 1 cup Monterey jack cheese (finely shredded)
  • 1 cup French fried onions
  • 1.5 tbsps garlic (minced)

Instructions

  1. Cook spaghetti in salted water until perfectly tender, approximately 8-10 minutes. Drain and rinse with cold water to halt cooking process, then set aside.
  2. Shred rotisserie chicken into bite-sized pieces, ensuring uniform texture for consistent flavor distribution throughout the casserole.
  3. Blend chicken with cream of chicken soup, sour cream, garlic, and baby spinach in a spacious mixing bowl, creating a creamy and vibrant base mixture.
  4. Fold prepared pasta into the chicken mixture, making certain each noodle is generously coated with the rich sauce.
  5. Grease a 9×13-inch baking dish with cooking spray to prevent potential sticking and facilitate easier serving.
  6. Transfer combined ingredients into the prepared dish, spreading evenly to create a smooth surface layer.
  7. Sprinkle remaining Monterey jack cheese across the top, creating a melty coverage, and scatter French fried onions for added crunch.
  8. Heat oven to 350°F and bake casserole for 40-45 minutes, or until cheese melts completely and edges turn golden brown.
  9. Remove from oven and allow to rest for 5-7 minutes before serving, enabling flavors to settle and casserole to firm slightly.

Notes

  • Customize the protein by swapping rotisserie chicken with leftover turkey, shredded beef, or plant-based alternatives for dietary flexibility.
  • Enhance nutrition by adding roasted vegetables like bell peppers, zucchini, or mushrooms to boost vegetable content without compromising flavor.
  • Reduce sodium and calories by using low-fat sour cream, reduced-sodium cream of chicken soup, and homemade crispy onion topping for a healthier version.
  • Make the dish gluten-free by substituting regular pasta with gluten-free noodles and ensuring all other ingredients are certified gluten-free.
