Description

A creamy, cheesy baked spaghetti casserole with chicken, spinach, sour cream, cream of chicken soup, Monterey Jack cheese and topped with crispy fried onions.


Ingredients

  • 12 oz dried spaghetti
  • 4 cups chopped cooked chicken
  • 1 (16‑oz) container sour cream
  • 2 (10.5‑oz) cans unsalted cream of chicken soup
  • 1 (10‑oz) package frozen spinach, thawed and drained
  • 2 cups shredded Monterey Jack cheese, divided
  • 2 garlic cloves, minced
  • 1 (6‑oz) can French’s French Fried Onions, divided

Instructions

  1. Preheat oven to 350°F and lightly spray a 9×13‑inch baking dish with cooking spray.
  2. Cook the spaghetti according to package directions until al dente, then drain.
  3. In a large bowl, combine the chopped cooked chicken, cream of chicken soup, sour cream, drained spinach, 1 cup of the Monterey Jack cheese, and minced garlic, plus half of the French fried onions.
  4. Stir in the cooked spaghetti until well mixed, then pour into the prepared baking dish.
  5. Sprinkle the remaining Monterey Jack cheese and the rest of the French’s fried onions on top.
  6. Bake uncovered for 40‑50 minutes, until the casserole is hot, bubbly, and the onions on top are golden brown.

Notes

  • You can make this casserole ahead of time and refrigerate or freeze for later. If baking after refrigerated, you may need to add a few minutes. If from frozen, thaw completely before baking.
  • Using unsalted cream of chicken soup helps control sodium levels. Adjust seasoning to taste.
  • If you don’t have frozen spinach, fresh spinach can be used—just wilt and drain off excess water.
  • For variation, you could substitute plain yogurt for sour cream, or add extra seasonings like garlic powder or onion powder.
