Step-by-Step Instructions
Follow these simple steps to create the perfect Monterey Chicken Spaghetti every time.
1. Cook the Pasta
Bring a large pot of salted water to a boil. Cook the spaghetti according to package directions until al dente. Before draining, reserve about one cup of the starchy pasta water. This will help thicken the sauce later if needed.
2. Sauté Chicken and Vegetables
While the pasta is cooking, heat olive oil and butter in a large skillet or Dutch oven over medium-high heat. Add the chicken pieces and season with salt and pepper. Cook until golden brown and cooked through. Remove the chicken from the skillet and set it aside. In the same skillet, add the diced onion and red bell pepper. Sauté for 4-5 minutes until they begin to soften. Add the minced garlic and cook for another minute until fragrant.
3. Build the Creamy Sauce
Sprinkle the chili powder, cumin, and smoked paprika over the vegetables and stir to combine. Pour in the chicken broth, heavy cream, and the undrained can of diced tomatoes with green chilies. Bring the mixture to a simmer and let it cook for 5-7 minutes, allowing the flavors to meld and the sauce to thicken slightly. For a different but equally creamy dish, try this Creamy German Goulash.
4. Combine and Melt
Reduce the heat to low and gradually stir in the shredded Monterey Jack cheese until it’s completely melted and the sauce is smooth. Return the cooked chicken to the skillet. Add the drained spaghetti and toss everything together until the pasta is fully coated in the glorious, cheesy sauce. If the sauce is too thick, add a splash of the reserved pasta water until it reaches your desired consistency.
5. Garnish and Serve
Stir in the fresh cilantro and serve your Monterey Chicken Spaghetti immediately. It pairs wonderfully with a side of crusty bread or a simple green salad. We recommend our Butter Swim Biscuits to soak up every last drop of the sauce.

Tips for the Best Monterey Chicken Spaghetti
- Shred Your Own Cheese: Pre-shredded cheese is often coated with anti-caking agents that can prevent it from melting smoothly. For the creamiest sauce, always buy a block of Monterey Jack and shred it yourself.
- Don’t Overcook the Pasta: Cook the spaghetti just until al dente. It will continue to cook slightly when you add it to the hot sauce.
- Control the Heat: The diced tomatoes with green chilies add a mild spice. If you prefer more heat, you can add a pinch of cayenne pepper or a chopped jalapeño with the onions and bell peppers.
Variations and Substitutions
One of the best things about this recipe is its versatility. Here are a few ideas to make it your own:
- Different Cheeses: Feel free to use a blend of cheeses. Colby Jack, Pepper Jack, or even a sharp cheddar would work well.
- Add More Veggies: Sliced mushrooms, spinach, or corn would be delicious additions. Add them in with the onions and peppers.
- Make it a Bake: For an extra cheesy, bubbly top, transfer the finished pasta to a baking dish, top with more Monterey Jack cheese, and bake at 375°F (190°C) for 15-20 minutes until golden.
Storage and Reheating Instructions
Store any leftover Monterey Chicken Spaghetti in an airtight container in the refrigerator for up to 3-4 days. To reheat, simply microwave in 30-second intervals, stirring in between, until heated through. You can also reheat it on the stovetop over low heat. If the sauce has thickened too much, add a splash of milk or chicken broth to loosen it up.
What to Serve with Monterey Chicken Spaghetti
This dish is a complete meal on its own, but it also pairs wonderfully with a variety of sides. Consider serving it with a fresh green salad with a light vinaigrette, some steamed or sautéed vegetables, or garlic bread for dipping into that amazing sauce.

Certainly. While spaghetti is classic, this sauce works beautifully with other pasta shapes like fettuccine, penne, or rotini. Just cook according to the package directions.
While you can freeze it, be aware that the texture of cream-based sauces can sometimes change upon thawing. If you choose to freeze it, let it thaw in the refrigerator overnight and reheat gently on the stovetop, adding a splash of milk or cream to restore the sauce’s consistency.
This recipe has a very mild level of spice from the diced tomatoes with green chilies. It’s generally kid-friendly. If you want to increase the heat, you can add a pinch of cayenne pepper or use a can of ‘hot’ diced tomatoes with green chilies.
