Ingredients

To make Cajun Chicken Alfredo, gather the following:

2 large boneless, skinless chicken breasts (about 1 lb / 450 g)
2 tablespoons Cajun seasoning (30 g), divided
1 teaspoon smoked paprika (5 g)
1 tablespoon olive oil (15 ml)
2 tablespoons unsalted butter (28 g)
3 cloves garlic, minced
1 ½ cups heavy cream (360 ml)
1 cup freshly grated Parmesan cheese (100 g)
½ teaspoon black pepper
8 oz fettuccine pasta (225 g)
½ teaspoon salt, plus more for pasta water
¼ teaspoon crushed red pepper flakes (optional)
2 tablespoons chopped fresh parsley (optional garnish)

Use freshly grated Parmesan for the smoothest sauce. Choose high-quality Cajun seasoning for bold, balanced flavor.

Pro Tips for the Best Cajun Chicken Alfredo

First, season generously but thoughtfully. Coat the chicken evenly with Cajun seasoning and paprika, pressing the spices into the meat. This technique builds a flavorful crust during searing and locks in moisture.

Second, cook the pasta just to al dente. Slightly firm pasta absorbs the sauce without becoming mushy. Reserve ½ cup of pasta water before draining. This starchy liquid helps loosen and emulsify the sauce if it thickens too much.

Third, control your heat when making the Alfredo sauce. Keep the cream at a gentle simmer, not a boil. High heat can cause separation or graininess once you add the cheese. Stir continuously and add Parmesan gradually for a smooth, glossy finish.

These three steps transform your Cajun Chicken Alfredo from good to restaurant-quality.

Step-by-Step Instructions

Step 1: Prepare the Pasta

Bring a large pot of salted water to a boil. Add the fettuccine and cook until al dente according to package instructions. Stir occasionally to prevent sticking. Before draining, reserve ½ cup of pasta water. Drain the pasta and set aside.

Step 2: Season the Chicken

Pat the chicken breasts dry with paper towels. Sprinkle 1 ½ tablespoons of Cajun seasoning and the smoked paprika evenly over both sides. Press the spices into the chicken so they adhere well.

Step 3: Sear the Chicken

Heat olive oil in a large skillet over medium-high heat. Add the chicken and cook for 5–6 minutes per side until golden brown and fully cooked. The internal temperature should reach 165°F (74°C). Remove the chicken from the skillet and let it rest for 5 minutes before slicing into strips.

Step 4: Build the Alfredo Sauce

Reduce the heat to medium. Add butter to the same skillet. Once melted, stir in minced garlic and cook for 30 seconds until fragrant. Pour in the heavy cream and bring it to a gentle simmer. Stir frequently.

Gradually whisk in the Parmesan cheese until the sauce thickens. Add the remaining ½ tablespoon Cajun seasoning, black pepper, and red pepper flakes if desired. Taste and adjust seasoning.

Step 5: Combine Everything

Add the drained pasta directly into the sauce. Toss well to coat every strand. If the sauce feels too thick, add a splash of reserved pasta water and stir until silky.

Top the pasta with sliced Cajun chicken. Garnish with chopped parsley and extra Parmesan. Serve immediately while hot and creamy.

This method ensures your Cajun Chicken Alfredo tastes rich, balanced, and perfectly spiced.

Variations

You can easily customize Cajun Chicken Alfredo to suit your preferences.

For a seafood twist, replace chicken with shrimp. Cajun shrimp Alfredo cooks even faster and delivers a slightly sweet contrast to the spice.

If you prefer a smoky upgrade, add crispy bacon bits. This variation appeals to fans of garlic pasta with bacon and adds crunch against the creamy sauce.

For a lighter option, swap heavy cream with half-and-half and reduce the Parmesan slightly. You can also use whole wheat pasta or gluten-free pasta without sacrificing flavor.

Vegetable lovers can stir in sautéed bell peppers, spinach, or mushrooms. These additions add color, nutrients, and texture while complementing the bold Cajun seasoning.

Storage and Serving Suggestions

Store leftover Cajun Chicken Alfredo in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat. Add a splash of milk or cream to restore the sauce’s smooth texture.

Avoid microwaving at high power, as intense heat can cause the sauce to separate. Stir frequently while reheating.

Serve this dish with warm garlic bread to soak up extra sauce. A crisp green salad with lemon vinaigrette balances the richness. Roasted broccoli or asparagus also pairs beautifully with the spicy cream sauce.

This pasta works wonderfully for date nights, family dinners, or casual gatherings where you want bold flavor without complicated prep.

FAQs

Can I make this less spicy?
Yes. Reduce the Cajun seasoning and skip the red pepper flakes. You can always add more heat later.
What pasta works best?
Fettuccine works beautifully, but penne or linguine also hold the sauce well.
Can I use pre-cooked chicken?
Yes, but fresh seared chicken adds more flavor and texture.
Why did my sauce turn grainy?
High heat often causes separation. Keep the sauce at a gentle simmer and add cheese gradually.
Can I freeze Cajun chicken pasta?
Freezing is not recommended. Cream-based sauces can separate and lose their smooth texture when thawed.
