Ingredients

12 ounces dried spaghetti: Your favorite brand will do!
4 cups chopped cooked chicken: Rotisserie chicken is a fantastic shortcut!

1 (16-ounce) container sour cream: Adds that perfect tang and creaminess.
2 (10.5-ounce) cans unsalted cream of chicken soup: The base of our creamy sauce.
1 (10-ounce) package frozen spinach, thawed and drained: Adds a pop of color and nutrition.

2 cups shredded Monterey Jack cheese: The star of the show! I love the mild, slightly nutty flavor.
2 garlic cloves, minced: For a little extra zing.
1 (6-ounce) can French’s French Fried Onions: The crispy, crunchy topping that makes this dish irresistible!

How to Make It

Let’s get cooking! Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish – I always use cooking spray for easy cleanup.

Cook the spaghetti according to the package directions until it’s perfectly al dente. Drain well – nobody likes soggy noodles!
In a large bowl, combine the cooked chicken, cream of chicken soup, sour cream, spinach, 1 cup of the Monterey Jack cheese, minced garlic, and half of the French Fried Onions. Give it a good stir until everything is nicely mixed.
Add the cooked spaghetti to the chicken mixture and gently stir to combine. Be careful not to break the spaghetti too much.

Pour the mixture into your prepared baking dish. Spread it evenly so it bakes consistently.
Sprinkle the remaining Monterey Jack cheese and French Fried Onions over the top. I like to get a nice even layer.
Bake uncovered for 40-50 minutes, or until it’s hot and bubbly, and the onions are golden brown and crispy. Keep an eye on it towards the end to prevent burning.

Substitutions & Additions

Feel free to get creative! You can substitute shredded cheddar cheese for the Monterey Jack, or add other veggies like mushrooms or bell peppers. For a spicier kick, add a pinch of red pepper flakes.

Tips for Success

Don’t overcook the spaghetti! Al dente is key for a perfect texture.
Make it ahead: You can assemble the casserole ahead of time and bake it just before serving. Just keep it refrigerated until ready to bake.

Use fresh garlic if you have it on hand! It will add a more intense garlic flavor.
If you want an extra crispy topping, add the remaining French fried onions during the last 5-10 minutes of baking.

How to Store It

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. I find it reheats beautifully in the microwave or oven.

FAQs

Can I use different cheese? Absolutely! Cheddar, Colby Jack, or even a Mexican blend would be delicious.
What if I don’t have French’s Fried Onions? You can omit them, or use crumbled toasted bread crumbs as a substitute.
Can I make this ahead of time? Yes, assemble the casserole the night before and bake it when you are ready to serve.

How do I know when it’s done? The casserole is ready when it’s bubbly, the cheese is melted, and the onions are golden brown.
