Ingredients for Creamy Cajun Chicken Spaghetti
- 1 lb boneless, skinless chicken breasts, cut into bite-sized pieces
- 8 oz spaghetti noodles
- 1 tablespoon olive oil
- 1 medium onion, diced
- 1 bell pepper, diced (any color)
- 3 cloves garlic, minced
- 2 tablespoons Cajun seasoning
- 4 cups chicken broth
- 1 cup heavy cream
- 1 cup shredded Monterey Jack cheese
- 1/2 cup grated Parmesan cheese
- Salt and pepper to taste
- Fresh parsley for garnish
Step-by-Step Instructions
Step 1: Cook the Chicken
Heat olive oil in a large skillet or Dutch oven over medium-high heat. Season chicken pieces with salt, pepper, and 1 tablespoon of Cajun seasoning. Cook until golden brown and cooked through, about 5-7 minutes. Remove chicken from skillet and set aside.
Step 2: Sauté Vegetables
In the same skillet, add onion and bell pepper. Cook until softened, about 3-4 minutes. Add garlic and cook for another minute until fragrant.
Step 3: Combine Ingredients
Add remaining Cajun seasoning to the vegetables, then pour in chicken broth. Bring to a boil. Break spaghetti noodles in half and add to the boiling broth. Cook according to package directions, stirring occasionally to prevent sticking.
Step 4: Create Creamy Sauce
When pasta is al dente, reduce heat to low. Stir in heavy cream and return the cooked chicken to the skillet. Add both cheeses and stir until melted and sauce has thickened.
Step 5: Final Touches
Taste and adjust seasoning if needed. Garnish with fresh parsley and serve immediately. For more cheesy chicken dishes that are perfect for busy nights, check out our skillet dinner collection.
Expert Tips for Perfect Cajun Chicken Spaghetti
Choose Your Spice Level: Cajun seasoning can vary in heat. Start with less and add more according to your preference. You can always add extra spice but can’t take it out!
Don’t Overcook the Pasta: Remember the pasta will continue cooking in the sauce, so pull it when it’s just al dente. This prevents mushy noodles in your final dish.
Fresh vs. Pre-made Seasoning: While store-bought Cajun seasoning works perfectly, making your own allows you to control the salt and spice levels more precisely.
Make It Ahead: This dish reheats beautifully. Store leftovers in an airtight container for up to 3 days. For another excellent creamy one-pan comfort dinner, try our chicken stroganoff recipe.
