Ingredients You’ll Need

You can adjust the spice level easily in this Creamy Cajun Chicken Recipe, so use these ingredients as a base and tweak to your taste.

Chicken

2 large boneless skinless chicken breasts
- Slice them horizontally into cutlets so they cook quickly and evenly.
1 teaspoon kosher salt
1/2 teaspoon black pepper
1 to 1 1/2 tablespoons Cajun seasoning
- Use a low-sodium Cajun blend if you have it, since some brands taste very salty.
- I often use Tony Chachere’s or Slap Ya Mama and then reduce extra salt.

For searing and sauce

2 tablespoons olive oil
1 tablespoon unsalted butter
3 cloves garlic, minced
- Use jarred minced garlic as a shortcut if needed, about 1 tablespoon.
1 cup low-sodium chicken broth
1 cup heavy cream
- Half-and-half works in a pinch, but the sauce turns slightly thinner.
1/2 cup grated parmesan cheese
- Use real parmesan from a wedge if possible, not the green can, so the sauce melts smoothly.
1 teaspoon smoked paprika
1/2 teaspoon onion powder
1/4 teaspoon dried thyme
1/4 teaspoon dried oregano
1/4 teaspoon crushed red pepper flakes
- Optional, adjust to taste if you like extra heat.
Salt and pepper to taste

Optional veggies (highly recommended)

- Penne, fettuccine, or rotini all work well.

Extra grated parmesan, to sprinkle on top

Tips & Tricks

Slice chicken breasts into thinner cutlets so they cook faster and stay juicy.
Pat chicken dry with paper towels before seasoning so you get a better sear.
Season both sides of the chicken generously with Cajun seasoning, then taste the sauce before adding extra salt.
Use medium-high heat to sear, then lower the heat when you add cream so it does not scorch.
Let the chicken rest on a plate while you build the sauce so the juices settle.
Scrape the browned bits from the bottom of the pan into the broth; those bits hold a ton of flavor.
Add parmesan off the heat or on low heat so it melts smoothly and does not clump.
Thin the sauce with a splash of broth or pasta water if it feels too thick.
Stir in spinach at the very end so it stays bright and tender, not mushy.
Taste the sauce before serving and adjust salt, pepper, and Cajun seasoning to your liking.

How to Make Creamy Cajun Chicken Recipe

Step 1: Prep the chicken

Lay the chicken breasts flat on a cutting board and slice them horizontally into 2 thinner cutlets each. Pat them dry on both sides. Season both sides with salt, pepper, and Cajun seasoning, pressing it in lightly so it sticks.

Step 2: Sear the chicken

Heat the olive oil and butter in a large skillet over medium-high heat. When the butter foams and looks slightly golden, add the chicken in a single layer without crowding. Sear 4 to 5 minutes per side until the chicken turns deep golden and the internal temperature reaches 165°F.

Move the cooked chicken to a plate and tent it loosely with foil. Keep the skillet on the stove because all those browned bits will flavor the sauce. If the pan looks very dry, add a small splash of oil.

Step 3: Cook the veggies

Lower the heat to medium. Add the sliced bell peppers and onion to the skillet and stir to coat them in the remaining fat and spices. Sauté 4 to 5 minutes until they soften and pick up some color.

Sprinkle in a pinch of salt to help them soften. If they start to brown too quickly, lower the heat slightly and stir more often.

Step 4: Build the Cajun cream base

Add the minced garlic to the skillet and cook about 30 seconds until fragrant. Pour in the chicken broth and use a wooden spoon to scrape up all the browned bits from the bottom of the pan. Stir in smoked paprika, onion powder, thyme, oregano, and crushed red pepper flakes.

Let the mixture simmer 2 to 3 minutes so it reduces slightly. This step concentrates the flavor and keeps the sauce from tasting watery.

Step 5: Add the cream and cheese

Lower the heat to medium-low. Pour in the heavy cream while you stir. Let it gently bubble, not boil hard, for 2 to 3 minutes until it starts to thicken.

Add the grated parmesan in small handfuls, stirring after each addition until it melts. Taste the sauce and adjust with more salt, pepper, or Cajun seasoning if needed. If the sauce feels too thick, add a splash of broth or a spoonful of pasta water.

Step 6: Finish the sauce with greens

Stir in the spinach and let it wilt for 1 to 2 minutes. The sauce should look glossy, creamy, and speckled with spices and veggies. If you want extra heat, sprinkle a bit more crushed red pepper now.

Step 7: Return the chicken to the skillet

Add the seared chicken and any juices from the plate back into the skillet. Spoon the sauce over the chicken so it coats each piece. Let everything simmer together on low heat for 3 to 5 minutes so the flavors blend and the chicken warms through.

Check the consistency of the sauce again and adjust with more cream or broth if you want it looser. Turn off the heat and garnish with chopped parsley or green onions.

Step 8: Serve

Serve the Creamy Cajun Chicken Recipe over hot pasta, rice, or mashed potatoes. Spoon plenty of sauce over the top so every bite tastes creamy and flavorful. Sprinkle extra parmesan on top if your heart says yes, which mine usually does.

What to Serve with Creamy Cajun Chicken Recipe

This Creamy Cajun Chicken Recipe pairs beautifully with pasta, white rice, brown rice, or fluffy mashed potatoes, since all of them soak up the sauce. Add a simple green salad or steamed broccoli on the side to balance the richness. Garlic bread or warm dinner rolls make a great side if you want to scoop up every last bit of sauce. For drinks, serve iced tea, sparkling water with lemon, or a light citrusy mocktail.

Storage Options

Store leftover Creamy Cajun Chicken Recipe in an airtight container in the fridge for up to 3 days.
Keep the sauce and pasta or rice separate if possible so the starch does not soak up all the sauce.
Freeze the chicken and sauce in a freezer-safe container for up to 2 months, and thaw overnight in the fridge before reheating.
Reheat gently in a skillet over low heat with a splash of cream, milk, or broth, or warm in the microwave in short bursts, stirring between bursts so the sauce stays smooth.
