Cheesy Monterey Chicken Spaghetti with Crunchy Topping (Print version)

A creamy baked chicken spaghetti casserole with Monterey Jack, spinach, sour cream, and a golden fried onion topping.

# Ingredients:

For the casserole

01 - 12 oz (340 g) dried spaghetti
02 - 3 cups (420 g) cooked chicken, chopped or shredded
03 - 2 cans (10.5 oz each/298 g each) cream of chicken soup
04 - 2 cups (480 g) sour cream
05 - 10 oz (280 g) frozen chopped spinach, thawed and squeezed dry
06 - 2 cloves garlic, minced
07 - 1 teaspoon onion powder
08 - 1/2 teaspoon black pepper
09 - 1/2 teaspoon kosher salt, plus more for pasta water
10 - 1 1/2 cups (170 g) shredded Monterey Jack cheese, divided
11 - 3 oz (85 g) French fried onions, divided

For the pan

12 - Nonstick cooking spray or 1 teaspoon butter

# Instructions:

01 - Preheat the oven to 350°F (175°C). Grease a 9x13-inch baking dish with nonstick spray or butter.
02 - Boil the spaghetti in salted water until just shy of al dente, about 1 minute less than the package directions. Drain well.
03 - In a large bowl, stir together the cooked chicken, cream of chicken soup, sour cream, drained spinach, garlic, onion powder, pepper, salt, 3/4 cup Monterey Jack, and half of the fried onions.
04 - Fold the drained spaghetti into the chicken mixture until the noodles are evenly coated. Use tongs to separate any clumps.
05 - Spread the mixture into the prepared baking dish. Sprinkle with the remaining Monterey Jack and the remaining fried onions.
06 - Bake uncovered for 40-45 minutes, until the edges bubble and the topping is golden. Let the casserole rest for 10 minutes before serving.

# Good to know:

01 - Best with rotisserie chicken or leftover roasted chicken.
02 - Squeeze thawed spinach very dry before mixing.
03 - Let the casserole rest before serving for cleaner portions.
