How to Make Monterey Chicken Spaghetti Casserole Recipe
Step 1: Prepare Your Pan and Pasta
Start by lightly spraying a 9×13-inch baking dish with cooking spray to keep everything from sticking and make cleanup easier. Meanwhile, cook the spaghetti according to package instructions until just al dente. Drain it well—making sure no water dilutes the creamy sauce you’re about to mix in.
Step 2: Mix the Creamy Components
In a large mixing bowl, combine the sour cream, cream of chicken soup, minced garlic, and half of the shredded Monterey Jack cheese. This mixture will be your casserole’s luscious sauce that binds everything together. Stir well to ensure it’s perfectly smooth and creamy before adding the other ingredients.
Step 3: Add the Spinach, Chicken, and Pasta
With the sauce ready, fold in the thawed and drained spinach, chopped cooked chicken, and the drained spaghetti. Gently toss everything together until every strand of pasta and piece of chicken is coated in that rich, cheesy sauce. This combination is where the magic of the Monterey Chicken Spaghetti Casserole Recipe really begins to shine.
Step 4: Pour Into the Baking Dish and Top
Transfer the mixture into your prepared pan, spreading it evenly. Sprinkle the remaining Monterey Jack cheese over the top, then add half of the French fried onions. This layering is crucial to achieving a cheesy, crunchy crust that makes biting into the casserole so delightful.
Step 5: Bake and Add Final Crunch
Bake in a preheated oven at 350°F (175°C) for about 35 minutes, or until the casserole is bubbly and the cheese on top is melted and golden. Five minutes before the end, sprinkle the rest of the French fried onions on top, then continue baking to get those onions perfectly crispy and browned. Let the dish rest a few minutes before serving to set beautifully.

Make Ahead and Storage
Storing Leftovers
Monterey Chicken Spaghetti Casserole Recipe keeps beautifully in an airtight container in the refrigerator for up to 3 days. The flavors meld beautifully overnight, making your leftovers even tastier!
Freezing
If you want to prepare this casserole in advance, it freezes very well. Wrap it tightly in foil or plastic wrap, then store it in a freezer-safe dish for up to 2 months. Make sure to thaw it slowly in the refrigerator before reheating.
Reheating
To reheat, simply cover the casserole with foil to prevent it from drying out and warm it in a 350°F oven for 20-25 minutes, or until heated through. You can also microwave individual portions, but the oven method helps keep the topping crisp and melty.
FAQs
Can I use fresh spinach instead of frozen for this casserole?
Absolutely! Just make sure to sauté and drain fresh spinach to remove excess moisture before mixing it into the casserole to avoid a watery dish.
What type of chicken works best for this recipe?
Cooked, shredded chicken breast or rotisserie chicken works perfectly. Just use what you have on hand for convenience and great flavor.
Can I substitute the sour cream for something else?
You can swap sour cream for plain Greek yogurt or cream cheese if you prefer a slightly different tang and creaminess, but sour cream gives the best traditional flavor here.
Is it necessary to use French fried onions?
While they add a delightful crunch and flavor, you could substitute with breadcrumbs or crushed crispy fried shallots for similar texture.
Can I make this casserole gluten-free?
Yes! Simply use gluten-free spaghetti and confirm that your cream of chicken soup and other canned ingredients are gluten-free to keep it safe for gluten sensitivities.
