Step 1: Prep Your Ingredients
Preheat your oven to 375°F (190°C). Cook the spaghetti according to the package instructions until it’s al dente. While the pasta is cooking, cook and crumble your bacon, and cook and shred the chicken if you aren’t using a rotisserie chicken. Chop your green onions and mince the garlic.
Step 2: Create the Creamy Sauce
In a large skillet or Dutch oven, heat the olive oil over medium heat. Add the minced garlic and cook for about 30 seconds until fragrant. Pour in the Alfredo sauce, BBQ sauce, and the can of diced tomatoes with green chilies. Stir well to combine and bring the sauce to a gentle simmer. Season with a pinch of salt and pepper.
Step 3: Combine Everything
Turn off the heat. Add the cooked and drained spaghetti, the shredded chicken, half of the crumbled bacon, half of the chopped green onions, and 1 cup of the shredded Monterey Jack cheese to the skillet with the sauce. Stir everything together until the pasta and chicken are fully coated in the creamy BBQ sauce.
Step 4: Bake to Perfection
Transfer the pasta mixture to a 9×13 inch baking dish. Sprinkle the remaining 1 cup of Monterey Jack cheese evenly over the top. Bake for 15-20 minutes, or until the cheese is completely melted and bubbly. For a golden-brown top, you can switch the oven to broil for the last 1-2 minutes, but watch it closely to prevent burning!
Step 5: Garnish and Serve
Remove the Monterey Chicken Spaghetti from the oven and let it rest for a few minutes. Garnish with the remaining crumbled bacon and chopped green onions. Serve hot and enjoy the cheesy goodness!
Expert Tips for the Best Results
Want to elevate your Monterey Chicken Spaghetti? Here are a few pro-tips:
- Don’t Overcook the Pasta: Cook your spaghetti just until al dente. It will continue to cook in the oven, and this prevents it from becoming mushy.
- Shred Your Own Cheese: For the best melt, buy a block of Monterey Jack and shred it yourself. Pre-shredded cheeses often contain anti-caking agents that can affect how smoothly they melt.
- Rotisserie Chicken Shortcut: Using a pre-cooked rotisserie chicken is the ultimate time-saver for this recipe. It’s flavorful, tender, and ready to go.
- Spice It Up: If you like a little more heat, add a pinch of red pepper flakes or a dash of hot sauce to the BBQ cream sauce. Or, try another spicy dish like our Cajun Steak Pasta for inspiration.
Recipe Variations & Substitutions
One of the best things about this recipe is how easy it is to customize. Try these variations:
- Different Pasta: No spaghetti? No problem! This dish works great with penne, fettuccine, or rotini.
- Cheese Swaps: Feel free to use Colby Jack, cheddar, or a Mexican cheese blend instead of Monterey Jack.
- Add Veggies: Sautéed bell peppers, onions, or mushrooms would be a fantastic addition. Stir them into the sauce with the chicken and pasta.
- Protein Change-Up: This recipe would also be delicious with shredded pork or even spicy Italian sausage.
Storing & Reheating Leftovers
This dish makes for fantastic leftovers. Store any remaining Monterey Chicken Spaghetti in an airtight container in the refrigerator for up to 4 days.
To reheat, you can microwave individual portions, or place the desired amount in an oven-safe dish, cover with foil, and bake at 350°F (175°C) for about 15-20 minutes, or until heated through. Adding a splash of milk or chicken broth before reheating can help restore its creaminess.
Yes! You can assemble the entire dish, cover it tightly, and refrigerate it for up to 24 hours before baking. You may need to add 5-10 minutes to the baking time if it’s going into the oven straight from the fridge.
Absolutely. While Monterey Jack is classic, this recipe is also fantastic with sharp cheddar, Colby Jack, or a Mexican cheese blend. Use your favorite melting cheese!
To add more heat, you can use a spicy BBQ sauce, add a pinch of red pepper flakes to the sauce, or use a can of hot diced tomatoes and green chilies (like Rotel Hot).
A store-bought rotisserie chicken is the quickest and easiest option. However, you can also use any cooked and shredded chicken breasts or thighs. It’s a great way to use up leftover chicken.
This dish is very rich and satisfying on its own, but it pairs wonderfully with a simple green salad with a vinaigrette dressing, steamed broccoli, or garlic bread to soak up the extra sauce.
