Ingredients

Before we begin cooking, gather and prepare the following ingredients. This recipe is designed to serve 4, but it can easily be doubled if you’re feeding a larger crowd.

For the Cajun Chicken:

• 4 boneless, skinless chicken breasts (or thighs, if preferred)

• 2 tablespoons olive oil

• 1 tablespoon unsalted butter

• 1 tablespoon Cajun seasoning (see below for homemade version)

• Salt and black pepper, to taste

For the Homemade Cajun Seasoning (optional but recommended):

• 1 teaspoon smoked paprika

• 1 teaspoon garlic powder

• 1 teaspoon onion powder

• ½ teaspoon dried oregano

• ½ teaspoon dried thyme

• ½ teaspoon cayenne pepper (adjust to taste)

• ½ teaspoon black pepper

• ½ teaspoon salt

For the Creamy Cheese Sauce:

• 2 tablespoons unsalted butter

• 2 cloves garlic, minced

• 2 tablespoons all-purpose flour

• 1 ½ cups whole milk (warm)

• ½ cup heavy cream

• 1 cup shredded cheddar cheese

• ½ cup shredded mozzarella cheese

• ¼ cup grated Parmesan cheese

• Salt and pepper, to taste

• Pinch of red pepper flakes (optional for heat)

Optional Add-Ins and Garnishes:

• 1 bell pepper (red or green), sliced thin

• 1 small onion, sliced thin

• 1 tablespoon chopped fresh parsley

• Fresh lemon juice for brightness

• Cooked pasta, rice, or mashed potatoes (as a base)

Step-by-Step Instructions

Step 1: Prep Your Ingredients

Start by preparing all your ingredients before heating the skillet. This makes the cooking process much smoother and quicker.

• If making homemade Cajun seasoning, combine all the spice mix ingredients in a small bowl and stir well.

• Pat the chicken dry with paper towels—this ensures it sears properly.

• Season the chicken on both sides with Cajun seasoning, salt, and black pepper. Be generous, but don’t oversalt if your Cajun mix already contains salt.

• Shred and set aside all cheeses. Pre-shredded cheese works, but freshly grated melts more smoothly and gives a better texture.

Step 2: Sear the Chicken

A perfectly seared piece of chicken is key to this dish—it locks in juices and creates a flavorful base for the sauce.

1. Heat 2 tablespoons of olive oil and 1 tablespoon of butter in a large cast-iron skillet or heavy-bottomed pan over medium-high heat.

2. Once the oil is shimmering and the butter is foaming, add the seasoned chicken breasts.

3. Sear the chicken undisturbed for 5–6 minutes on the first side, or until a golden-brown crust forms.

4. Flip and cook for another 4–5 minutes on the other side, depending on thickness, until the internal temperature reaches 165°F (74°C).

5. Remove the chicken from the skillet and set aside on a plate. Cover loosely with foil to keep warm.

Pro Tip: If you’re using thick chicken breasts, consider slicing them in half horizontally or pounding them to even thickness before cooking to ensure even searing and doneness.

Step 3: Sauté Aromatics (Optional)

If you’re using onions and bell peppers, this is the time to cook them.

1. In the same skillet (with the flavorful browned bits still in the pan), reduce heat to medium.

2. Add a little more oil or butter if needed, then toss in the sliced onion and bell pepper.

3. Cook for 4–5 minutes, stirring occasionally, until they’re soft and slightly caramelized.

4. Remove from skillet and set aside. These will be added back later for extra flavor and texture.

Step 4: Make the Roux for the Cheese Sauce

A roux is a cooked mixture of fat and flour that thickens sauces. It’s the foundation for a smooth, velvety cheese sauce.

1. In the same skillet, reduce heat to medium-low and add 2 tablespoons of butter.

2. Once melted, stir in 2 tablespoons of flour.

3. Cook the flour in the butter for about 1–2 minutes, stirring constantly. This removes the raw flour taste and creates a nutty aroma.

4. Slowly whisk in the warm milk. Add a little at a time, whisking continuously to avoid lumps.

5. Pour in the heavy cream and continue whisking until the sauce begins to thicken, about 3–5 minutes.

Pro Tip: If the sauce becomes too thick, you can add a splash of milk to loosen it.

Step 5: Add the Cheese

Once your base sauce is smooth and slightly thickened, it’s time to add the cheeses.

1. Reduce the heat to low. Slowly stir in the shredded cheddar, mozzarella, and Parmesan cheeses.

2. Stir constantly until all the cheese has melted and the sauce is silky and smooth.

3. Season with salt, black pepper, and a pinch of red pepper flakes if you like a bit of heat.

4. Taste and adjust seasoning as needed.

Step 6: Combine Everything

1. Return the seared chicken (and sautéed veggies if using) to the skillet, nestling them into the cheese sauce.

2. Spoon some of the sauce over each piece of chicken.

3. Cover the skillet with a lid or foil and let it simmer on low heat for 5 minutes to allow flavors to meld.

Optional Finish: For a bubbly golden topping, you can place the skillet under a broiler for 2–3 minutes. Just be sure your skillet is oven-safe.

Step 7: Serve

Remove from heat and let the dish rest for a few minutes before serving. Sprinkle with chopped parsley and a light squeeze of fresh lemon juice if desired. Serve hot, either as-is or over your favorite base:

• Creamy mashed potatoes

• Steamed white or brown rice

• Al dente pasta

• Garlic bread and a fresh green salad
