How to Make the Recipe

Step 1: Season and Sear the Chicken

Rub the chicken with Cajun seasoning. Heat olive oil in a large pot or skillet and sear chicken on both sides until golden brown and cooked through. Remove and set aside.

Step 2: Sauté Aromatics

In the same pot, add a little more oil if needed. Sauté chopped onion and minced garlic until fragrant and softened.

Step 3: Add Liquids and Pasta

Pour in chicken broth and heavy cream. Bring to a boil, then add uncooked pasta. Reduce heat and simmer, stirring occasionally, until pasta is al dente and liquid is slightly reduced.

Step 4: Stir in Cheese

Add grated Parmesan cheese, salt, and black pepper. Stir until cheese is melted and the sauce is smooth and creamy.

Step 5: Return Chicken and Serve

Slice the cooked chicken and return it to the pot. Stir to combine. Garnish with fresh parsley and serve hot.

Tips for Making the Recipe

Use Freshly Grated Cheese – It melts more smoothly than pre-shredded versions.
Cut Chicken Evenly – Uniform pieces ensure even cooking and better texture.
Adjust Spice to Taste – Cajun seasoning varies by brand—start small and build flavor.
Stir Pasta Frequently – Prevents sticking and ensures even cooking in one pot.
Let Sauce Thicken Slightly – It will continue to thicken as it cools, so don’t overcook.

How to Serve

Serve One Pot Cajun Chicken Alfredo hot, topped with extra Parmesan and a sprinkle of parsley. It pairs beautifully with a crisp green salad, garlic bread, or roasted vegetables. For a complete meal, add a side of steamed broccoli or sautéed spinach.

Make Ahead and Storage

Storing Leftovers

Cool completely and store in an airtight container in the refrigerator for up to 3 days.

Freezing

Not ideal due to the cream-based sauce, which may separate. If freezing, reheat gently with added cream or broth to restore texture.

Reheating

Reheat gently on the stovetop or in the microwave with a splash of cream or milk to revive the sauce.
