Creamy Monterey Chicken Spaghetti is the kind of comforting dinner that never lasts long at our table. Tender chicken, rich cheeses, and perfectly cooked pasta come together in a dish that feels like a warm hug, with just enough flavor to keep you coming back for another bite.
I first made this dish when I wanted to change up classic chicken Alfredo and my family immediately requested it again. Now it is a steady favorite at gatherings because everyone gets excited for that creamy Monterey Jack flavor.
Ingredients
- Chicken breast: boneless and skinless brings lean protein and cooks quickly I like to look for plump moist fillets
- Spaghetti: absorbs the creamy sauce and has the right texture for tossing Choose a quality brand for best results
- Olive oil: helps sear the chicken and build flavor Use extra virgin for a richer taste
- Diced onions: give the base sweetness and depth Fresh onions make a big difference here
- Garlic minced: creates a savory aromatic foundation Always use fresh cloves if possible
- Heavy cream: turns the sauce silky and thick Check that your cream is fresh and not ultra pasteurized for best flavor
- Monterey Jack cheese shredded: melts into a mild creamy sauce Always shred your cheese off the block for a smoother finish
- Parmesan cheese grated: adds nutty sharpness Fresh grated Parmesan gives much more kick than pre-shredded
- Smoked paprika: brings a hint of warmth and smokiness Spanish varieties have a more authentic flavor
- Black pepper: seasons both chicken and sauce use freshly ground if possible
- Salt: highlights every component Kosher salt brings balanced flavor
- Chopped fresh parsley: adds herby brightness Choose vibrant green flat leaf parsley for best flavor
- Butter: enriches the sauce and boosts sauté flavors Look for a high-butterfat European style stick if you want to splurge
- Chicken broth: loosens the sauce and layers in savory richness Homemade or low sodium works best
- Crushed red pepper flakes (optional): for a touch of heat Only use if you like a little spicy kick
Step-by-Step Instructions
- Boil and Drain the Pasta:
- Cook the spaghetti in salted water according to the package directions until just al dente Drain well but do not rinse Set aside while you prepare the rest
- Cook the Chicken:
- Warm olive oil in a large skillet over medium heat Season both sides of the chicken breasts with salt black pepper and smoked paprika Place chicken in the skillet and cook without moving for about six to seven minutes on each side until golden and cooked through The outsides should be browned and an instant-read thermometer should read 165 degrees Remove the cooked chicken and let it rest before slicing it into strips
- Build the Sauce Base:
- Melt butter in the same skillet used for the chicken over medium heat Add diced onions and minced garlic stirring consistently for two to three minutes until softened and fragrant The onions should become translucent but not browned This is your flavor foundation
- Simmer the Sauce:
- Pour chicken broth into the skillet and bring to a gentle simmer Scrape up any brown bits for extra flavor Stir in the heavy cream and allow it to cook for another two minutes so it starts to thicken slightly
- Add Cheese and Make Creamy:
- Reduce heat to low Stir in shredded Monterey Jack cheese and grated Parmesan cheese Do this gradually until the sauce is smooth silky and everything is fully melted This step makes the sauce extra creamy and rich
- Combine with Pasta:
- Add the cooked spaghetti to the skillet Toss everything until the pasta is fully coated in sauce Make sure every strand gets covered
- Finish and Serve:
- Arrange sliced chicken on top Sprinkle with fresh parsley and if you want a little spice a pinch of crushed red pepper flakes Serve hot and enjoy every creamy bite

Storage Tips
Store leftovers in an airtight container in the refrigerator for up to three days If the sauce thickens in the fridge add a splash of milk or chicken broth when reheating gently on the stovetop to revive its creaminess Avoid microwaving the chicken for too long as it can become tough
Ingredient Substitutions
If you do not have Monterey Jack cheese you can use mozzarella for meltiness or cheddar for a sharper bite For a gluten-free version swap spaghetti for your favorite rice noodle or gluten-free pasta If you do not have heavy cream you can use half-and-half and just reduce the broth a little or thicken with a touch of cornstarch

Serving Suggestions
Serve this pasta with a leafy green salad and some crusty bread for a complete meal You can also roast a few cherry tomatoes or broccoli florets alongside the chicken to add color and vegetables to the plate My family loves it with garlic bread and a squeeze of lemon for brightness
Cultural Context
Inspired by Southwestern flavors Monterey Jack cheese traces its history to California originally popularized in Monterey by Mexican Franciscan friars Today it is a classic cheese in American and Mexican fusion cooking Sautéing smoked paprika brings in a just-right touch of spice and depth a nod to that Southwest flavor
