How to Make Monterey Chicken Spaghetti: A Delicious & Easy Recipe
Step 1: Prepare the Oven and Cook Chicken
Begin by preheating your oven to 350°F (175°C) so it’s perfectly ready for baking later. Heat olive oil in a large skillet over medium heat. Season your diced chicken breasts with garlic powder, onion powder, salt, and pepper, then sauté until the chicken is beautifully browned and fully cooked, about 5 to 7 minutes. This step builds the flavorful base for the dish, ensuring every bite is juicy and seasoned just right.
Step 2: Add Bell Peppers and Onions
Once your chicken is cooked, toss in the diced red bell pepper and onion. Sauté them together for another 3 to 4 minutes until they soften slightly but still retain a bit of their crunch and sweetness. This adds great texture and fresh flavor contrast to the creamy components.
Step 3: Mix the Sauce and Spaghetti
In a large mixing bowl, combine your cooked and drained spaghetti with the chicken and vegetable mixture. Add the drained Rotel tomatoes with green chilies, cream of chicken soup, sour cream, milk, and 1 1/2 cups of shredded Monterey Jack cheese. Stir everything gently until it’s well blended, creamy, and loaded with cheesy goodness.
Step 4: Assemble and Bake
Grease a 9×13-inch baking dish lightly, then pour in your spaghetti and chicken mixture, spreading it evenly. Sprinkle the remaining 1/2 cup of shredded Monterey Jack cheese on top to create that irresistible bubbly crust. Pop it into the oven and bake for 25 to 30 minutes until the casserole is hot, bubbly, and the cheese is melted and slightly golden.
How to Serve Monterey Chicken Spaghetti: A Delicious & Easy Recipe

Garnishes
A sprinkle of fresh chopped parsley right before serving brightens the dish with color and a touch of herbaceous flavor that complements the creamy sauce beautifully. If you want a little extra punch, a dash of crushed red pepper flakes or sliced green onions can elevate the presentation and taste wonderfully well.
Side Dishes
This dish is hearty, so pairing it with a crisp green salad with a light vinaigrette balances out the richness perfectly. Garlic bread or warm dinner rolls are excellent options if you’re aiming for a more indulgent meal. For something lighter, steamed or roasted veggies like broccoli or asparagus add freshness and texture without stealing the spotlight.
Creative Ways to Present
For a fun twist, try serving Monterey Chicken Spaghetti family-style straight out of the baking dish for a cozy dinner vibe. Alternatively, portions can be scooped into individual ramekins for pretty, personalized servings that look as fantastic as they taste. Adding a small side of sliced avocado or a dollop of salsa can bring a new layer of flavor and visually pleasing contrast.
Make Ahead and Storage
Storing Leftovers
After your Monterey Chicken Spaghetti has cooled, transfer leftovers to an airtight container and refrigerate. It will keep well for up to 3 to 4 days, making it a perfect meal to enjoy the next day or two without losing any flavor or creaminess.
Freezing
This dish is freezer-friendly before baking, which means you can prepare it completely and freeze it in its baking dish or freezer-safe container. When ready to eat, thaw overnight in the fridge and then bake as directed. This makes it a fantastic option for meal prepping or planning ahead for busy weeks.
Reheating
To reheat, warm individual servings in the microwave or place the whole dish back in the oven at 350°F until heated through and bubbly again. Cover with foil to prevent the cheese from drying out if reheating longer. You’ll find the creamy texture and cheesy delight remain just as comforting as the first time.
FAQs
Can I use a different type of pasta?
Absolutely! While spaghetti works wonderfully here, you can use other pasta shapes like penne, rotini, or elbow macaroni. Just be sure to adjust cooking times according to the pasta instructions and keep in mind that different shapes may hold the sauce slightly differently.
Can I substitute the cheese?
Yes, Monterey Jack cheese is mild and creamy, but Mexican cheese blends or pepper jack add extra flavor and a little kick. Feel free to experiment with your favorite cheeses to tailor the dish to your taste.
Is this dish spicy?
The Rotel tomatoes with green chilies provide a gentle warmth, but it’s not very spicy. You can adjust the spice level by choosing mild or hot Rotel varieties or adding your own chili powder or hot sauce if you want more heat.
What if I don’t have cream of chicken soup?
You can make a quick homemade substitute by mixing some chicken broth, milk, and a bit of flour or cornstarch to thicken. This keeps the creamy texture without relying on canned soup.
Can this recipe be made dairy-free?
To make a dairy-free version, substitute the sour cream and cheese with plant-based alternatives, and use a dairy-free cream soup. Using olive oil or a vegan butter substitute will keep the richness intact while accommodating dietary needs.
