What Makes This Monterey Chicken Spaghetti So Special?

This recipe stands out from the rest. We’ve focused on developing deep, rich flavors and a velvety texture that makes every bite a dream.

The Creamiest, Dreamiest Cheese Sauce

The heart of this dish is its sauce. We use a combination of Monterey Jack and sharp cheddar for the perfect balance of meltiness and flavor, enriched with cream cheese for an ultra-smooth consistency. A can of diced tomatoes and green chiles adds a gentle spice and tang that cuts through the richness beautifully.

Perfectly Seasoned Chicken

We don’t just add plain chicken. Our recipe calls for seasoning the chicken with a blend of spices before cooking, ensuring that every piece is packed with flavor and contributes to the overall deliciousness of the dish.

A Crowd-Pleasing Casserole

This Monterey Chicken Spaghetti is a true one-pan wonder that’s perfect for feeding a family. It’s hearty, satisfying, and combines protein, carbs, and dairy in one perfect package. Plus, it reheats beautifully, making it ideal for leftovers.

Key Ingredients for Success

While the full ingredient list is in the recipe card below, here are the key players that make this dish a standout:

• Spaghetti: The classic choice, but feel free to use other pasta shapes like penne or rotini.
• Chicken: Boneless, skinless chicken breasts or thighs work perfectly. We’ll dice them for even cooking.
• Monterey Jack Cheese: The star of the show! For the best results, grate your own cheese. It melts much better than pre-shredded varieties.
• Cheddar Cheese: Adds a sharp, tangy flavor that complements the milder Monterey Jack.
• Diced Tomatoes and Green Chiles: A can of Ro-Tel or a similar product provides a signature Tex-Mex flavor and a gentle heat.
• Cream Cheese: The secret weapon for an unbelievably creamy and stable sauce.
• Bacon: Adds a salty, smoky crunch that takes this dish over the top.

Step-by-Step Guide to Making Monterey Chicken Spaghetti

Making this cheesy masterpiece is easier than you think. Follow these simple steps for a perfect pasta bake every time.

1. Cook the Bacon and Chicken: In a large skillet or Dutch oven, cook the chopped bacon until crispy. Remove the bacon, leaving the rendered fat in the skillet. Add the seasoned, diced chicken and cook until golden brown and cooked through. Remove the chicken and set it aside.
2. Sauté the Aromatics: In the same skillet, sauté the diced onion and bell pepper until softened. Add the minced garlic and cook for another minute until fragrant.
3. Create the Creamy Sauce: Stir in the flour to create a roux. Gradually whisk in the chicken broth and milk until smooth. Bring the mixture to a simmer, then reduce the heat and stir in the cream cheese until it has completely melted.
4. Melt the Cheeses: Slowly add the shredded Monterey Jack and cheddar cheeses, stirring constantly until you have a smooth, velvety sauce. Stir in the diced tomatoes and green chiles.
5. Combine Everything: While you make the sauce, cook your spaghetti according to package directions until al dente. Drain it well. Return the cooked chicken to the skillet with the sauce. Add the drained spaghetti and half of the crispy bacon, stirring until everything is well-coated.
6. Bake to Perfection: Transfer the mixture to a baking dish. Top with the remaining cheese and crispy bacon. Bake until the sauce is bubbly and the top is golden brown. Let it rest for a few minutes before serving.

Pro-Tips for the Best Results

Unlock the full potential of your Monterey Chicken Spaghetti with these expert tips.

• Shred Your Own Cheese: Pre-shredded cheeses contain anti-caking agents that can make your sauce gritty. Grating a block of cheese by hand is the number one secret to a silky-smooth sauce.
• Don’t Overcook the Pasta: Cook the spaghetti until it’s just al dente. It will continue to cook in the oven, and this prevents it from becoming mushy.
• Salt Your Pasta Water: This is a fundamental step for flavorful pasta. The water should taste like the sea. This ensures the spaghetti itself is seasoned from the inside out.

Delicious Variations to Try

While this recipe is fantastic as is, it’s also incredibly versatile. Feel free to customize it to your liking!

• Spice It Up: For extra heat, add a diced jalapeño along with the onions or a pinch of cayenne pepper to the sauce.
• Add More Veggies: Stir in some sautéed mushrooms, spinach, or corn to boost the vegetable content. For a well-rounded meal, serve it alongside some Healthy Sautéed Vegetables.
• Different Proteins: This recipe would also be delicious with leftover shredded rotisserie chicken to save time, or even cooked and crumbled Italian sausage for a different flavor profile.

What to Serve with Your Pasta Bake

This is a hearty meal on its own, but a simple side can complete the dinner table. A fresh green salad with a light vinaigrette is a great choice. For something more substantial, you can’t go wrong with warm, fluffy Butter Swim Biscuits to soak up every last bit of that amazing cheese sauce. For another comfort food classic, consider a bowl of creamy chicken poblano soup.

Storage and Reheating Instructions

One of the best things about this Monterey Chicken Spaghetti is how well it keeps!

• To Store: Let the casserole cool completely, then cover it tightly or transfer it to an airtight container. It will last in the refrigerator for up to 4 days.
• To Reheat: For individual portions, the microwave works well. For larger amounts, place the casserole in an oven-safe dish, cover with foil, and bake at 350°F (175°C) for 20-25 minutes, or until heated through.
• To Freeze: You can freeze the entire casserole before baking. Assemble as directed in a freezer-safe dish, cover tightly with plastic wrap and then foil, and freeze for up to 3 months. Thaw in the refrigerator overnight before baking as directed, adding 10-15 minutes to the baking time.

Ingredients Equipment Method Notes

Ingredients

  

• 1 lb spaghetti
• 1.5 lbs boneless, skinless chicken breasts cut into 1-inch cubes
• 6 slices bacon chopped
• 1 tbsp olive oil if needed
• 1 tsp smoked paprika
• 1 tsp garlic powder
• 0.5 tsp onion powder
• Salt and black pepper to taste
• 1 medium onion diced
• 1 red bell pepper diced
• 3 cloves garlic minced
• 3 tbsp all-purpose flour
• 1.5 cups chicken broth
• 1 cup milk whole milk preferred
• 4 oz cream cheese softened and cubed
• 8 oz Monterey Jack cheese shredded, divided
• 4 oz sharp cheddar cheese shredded
• 10 oz can diced tomatoes and green chiles undrained (like Ro-Tel)

Equipment

• 1 Large skillet or Dutch oven
• 1 9x13 inch baking dish
• 1 Large Pot (for pasta)

Method

 

1. Preheat your oven to 375°F (190°C). Cook the spaghetti according to package directions until al dente. Drain and set aside.
2. While the pasta cooks, combine the cubed chicken with the smoked paprika, garlic powder, onion powder, salt, and pepper.
3. In a large, oven-safe skillet or Dutch oven over medium-high heat, cook the chopped bacon until crispy. Remove the bacon with a slotted spoon and set aside, reserving about 2 tablespoons of bacon fat in the skillet.
4. Add the seasoned chicken to the skillet and cook until golden brown and cooked through, about 5-7 minutes. Remove the chicken and set aside.
5. Add the diced onion and bell pepper to the skillet, cooking until softened, about 5 minutes. Add the minced garlic and cook for 1 more minute until fragrant.
6. Sprinkle the flour over the vegetables and stir for 1 minute to cook out the raw taste. Gradually whisk in the chicken broth and milk until the mixture is smooth.
7. Bring to a simmer, then reduce the heat to low. Stir in the cubed cream cheese until it melts completely into the sauce.
8. Remove from heat and gradually stir in 6 oz of the Monterey Jack cheese and all of the cheddar cheese until melted and smooth. Stir in the can of diced tomatoes and green chiles.
9. Add the cooked spaghetti, cooked chicken, and half of the crumbled bacon to the cheese sauce. Stir until everything is thoroughly coated.
10. Top the spaghetti with the remaining 2 oz of Monterey Jack cheese and the rest of the crispy bacon. Transfer the skillet to the preheated oven (or pour into a 9x13 baking dish) and bake for 15-20 minutes, or until the sauce is bubbly and the top is golden.
11. Let it rest for 5-10 minutes before serving.

Notes

For the best, creamiest sauce, shred your own cheese from a block. Pre-shredded cheeses have additives that can make the sauce grainy.
Be sure to cook your pasta al dente, as it will continue cooking in the oven.
Feel free to adjust the spice level by choosing a 'hot' can of diced tomatoes and chiles or adding a pinch of cayenne pepper to the sauce.
