Proteins
- 2 boneless, skinless chicken breasts, cut into bite-sized pieces
Seasonings and Spices
- 2–3 tablespoons Cajun seasoning (paprika, cayenne, garlic, herbs blend)
- Salt, to taste
- Black pepper, to taste
Pasta and Liquids
- 8 ounces fettuccine pasta
- 2 cups chicken broth
- 1 ½ cups heavy cream
Dairy
- ½ cup freshly grated Parmesan cheese
- 3 tablespoons butter (divided)
Aromatics
- Season and Sear the Chicken: Cut the chicken breasts into bite-sized pieces and generously coat them in Cajun seasoning. Heat 2 tablespoons of butter in a large skillet or deep pot over medium-high heat. Add the chicken and cook until golden brown and just cooked through, about 5-7 minutes. Remove chicken from the pot and set aside.
- Sauté Garlic and Build Flavor: In the same pot, add the remaining 1 tablespoon of butter if needed and toss in the minced garlic. Sauté until fragrant, about 30 seconds to 1 minute, taking care not to burn it. This creates an aromatic base for the sauce.
- Add Liquids and Pasta: Pour in the chicken broth and heavy cream, stirring to combine thoroughly. Bring the mixture to a gentle boil, then add the fettuccine pasta, pushing it down so it is fully submerged. Reduce heat to medium-low, cover the pot, and cook for 12-15 minutes, stirring occasionally, until the pasta is tender and has absorbed the creamy sauce.
- Return Chicken and Add Cheese: Once the pasta is cooked, return the chicken to the pot. Stir in freshly grated Parmesan cheese to thicken the sauce and add a rich, cheesy finish. Season with salt and black pepper to taste.
- Serve and Enjoy: Give the pasta a final stir to ensure everything is well combined and heated through. Serve immediately, garnished with fresh parsley, chopped green onions, or extra Parmesan if desired.
Notes
- Use freshly grated Parmesan cheese for the best melting and flavor.
- Do not overcook chicken; sear until just cooked to keep it tender and juicy.
- Stir the sauce frequently while cooking pasta to prevent sticking and ensure even creaminess.
- If your pot is small, add pasta gradually to keep it submerged in the liquid.
- Adjust Cajun seasoning to your preferred spice level by adding more or less cayenne.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently with a splash of cream or broth.
- Freeze leftovers for up to 1 month; thaw overnight in fridge before reheating carefully to avoid sauce separation.
