Step‑by‑Step Instructions for Creamy Cajun Chicken Spaghetti with Garlic Mozzarella Sauce
Step 1: Season the Chicken
Begin by seasoning 1 lb of boneless, skinless chicken breasts with Cajun seasoning and a sprinkle of smoked paprika. Allow the chicken to rest for 10 minutes to let the spices penetrate the meat, enhancing the flavors. This short resting period is essential for an elevated taste in your Creamy Cajun Chicken Spaghetti.
Step 2: Cook the Chicken
In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Once hot, add the seasoned chicken breasts and cook for 6-8 minutes on each side, or until they are golden brown and cooked through. Use a meat thermometer to ensure they reach an internal temperature of 165°F. After cooking, remove the chicken from the skillet and set it aside on a cutting board.
Step 3: Sauté Garlic
In the same skillet, reduce the heat to medium and add 4 tablespoons of butter. Once melted, incorporate 4 minced garlic cloves and sauté for about 1 minute until fragrant, stirring frequently to prevent burning. As the garlic turns golden, it will release a wonderful aroma that sets the stage for your creamy sauce.
Step 4: Make the Roux
Whisk in 1/4 cup of all-purpose flour to the garlic-butter mixture, stirring continuously for about 1 minute. This roux will help thicken your sauce beautifully, adding a rich texture to the Creamy Cajun Chicken Spaghetti. Keep an eye on it, as the color should remain light and not brown.
Step 5: Add Liquid Ingredients
Gradually pour in 3 cups of whole milk and 1 cup of chicken broth, whisking constantly to prevent any lumps. Continue to cook the mixture over medium heat for 3-4 minutes until it begins to thicken and bubble gently. This creamy base is vital for enveloping the pasta and chicken in richness, so be patient during this step.
Step 6: Incorporate Cream Cheese
Add 8 ounces of softened cream cheese to the skillet, stirring until it melts completely and the sauce is smooth and velvety. Taste the sauce and adjust the seasoning with salt and black pepper as needed. The Creamy Cajun Chicken Spaghetti sauce should have a rich flavor with a kick of spice that complements the pasta perfectly.
Step 7: Combine Pasta and Chicken
Fold in the cooked spaghetti, ensuring it is well-coat with the creamy sauce. Then, dice the cooked chicken and add it back to the skillet, stirring to combine everything evenly. Allow the dish to simmer on low heat for an additional 2-3 minutes to meld the flavors, ensuring each bite of your Creamy Cajun Chicken Spaghetti is packed with taste.
Step 8: Finish and Broil
Transfer the entire mixture to an oven-safe dish and top with 1/2 cup of mozzarella cheese. Place it under the broiler for 2-3 minutes until the cheese is melted and golden brown. Keep a close watch on it, as broiling can quickly change from perfect to burnt. This final step adds a delightful cheesy crust to your meal, making it a true comfort dish.
