Ingredients
- 1 lb chicken breast, cut into bite-sized pieces
- 8 oz spaghetti noodles
- 1 tablespoon olive oil
- 1 medium onion, diced
- 3 cloves garlic, minced
- 1 bell pepper, diced
- 2 tablespoons Cajun seasoning
- 1 cup heavy cream
- 1/2 cup chicken broth
- 1 cup grated Parmesan cheese
- Salt and black pepper to taste
- Fresh parsley for garnish
Step-by-Step Instructions
Step 1: Cook the Chicken
Heat olive oil in a large skillet over medium-high heat. Add the chicken pieces and cook for 5-6 minutes until golden brown and cooked through. Remove chicken from skillet and set aside.
Step 2: Sauté Vegetables
In the same skillet, add the diced onion and bell pepper. Cook for 3-4 minutes until softened. Add minced garlic and cook for another minute until fragrant.
Step 3: Build the Sauce
Sprinkle Cajun seasoning over the vegetables and stir to coat. Pour in chicken broth to deglaze the pan, scraping up any browned bits. Add the heavy cream and bring to a gentle simmer.
Step 4: Cook the Pasta
Add uncooked spaghetti noodles to the skillet, making sure they’re submerged in the creamy sauce. Cover and simmer for 12-15 minutes, stirring occasionally, until pasta is al dente.
Step 5: Combine and Finish
Return the cooked chicken to the skillet along with Parmesan cheese. Stir until cheese is melted and sauce is creamy. Season with salt and pepper to taste. Garnish with fresh parsley before serving.
Expert Tips for Perfect Cajun Chicken Spaghetti
Adjust the Heat Level: Cajun seasoning can vary in spiciness. Start with 1 tablespoon and add more gradually if you prefer extra heat. For milder spice, use half the amount.
Don’t Overcook the Pasta: The noodles will continue to cook in the residual heat, so remove them from the heat when they’re al dente. This prevents them from becoming mushy.
Creamy Sauce Consistency: If your sauce thickens too much, add a splash of chicken broth to thin it out. For a thicker sauce, let it simmer uncovered for a few extra minutes.

Short FAQ
Can I use different pasta shapes?
Absolutely! While spaghetti works beautifully, you can substitute linguine, fettuccine, or even penne pasta. Just adjust cooking times accordingly.
How do I store leftovers?
Store in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop with a splash of broth to refresh the creamy sauce.
Can I make this dish ahead?
You can prep the chicken and chop vegetables ahead of time, but for best results, cook the pasta fresh when ready to serve. The noodles can become too soft if stored in the sauce overnight.
