Gather Your Ingredients
For the Blackened Cajun Chicken:
- 1.5 lbs boneless, skinless chicken breasts, cut into 1-inch pieces
- 2 tablespoons olive oil
- 2 tablespoons Cajun seasoning (store-bought or homemade – recipe below)
- 1 teaspoon smoked paprika
- 1/2 teaspoon garlic powder
- 1/4 teaspoon cayenne pepper (optional, for extra heat)
- Salt and black pepper to taste
For the Homemade Cajun Seasoning (Optional):
- 1 tablespoon paprika
- 2 teaspoons garlic powder
- 2 teaspoons onion powder
- 1 teaspoon dried oregano
- 1 teaspoon dried thyme
- 1 teaspoon black pepper
- 1/2 teaspoon cayenne pepper (adjust to your spice preference)
- 1/2 teaspoon red pepper flakes (optional)
- 1 teaspoon salt
For the Alfredo Sauce:
- 1/2 cup (1 stick) unsalted butter
- 4 cloves garlic, minced
- 2 cups heavy cream
- 1 cup grated Parmesan cheese, plus more for serving
- 1/4 teaspoon nutmeg
- Salt and black pepper to taste
- 1/4 cup chopped fresh parsley, for garnish (optional)
For the Pasta:
- 1 pound fettuccine pasta
- Salt, for pasta water
Let’s Make Some Magic: Step-by-Step Instructions
Step 1: Cook the Pasta
- Bring a large pot of salted water to a rolling boil.
- Add the fettuccine pasta and cook according to package directions until al dente.
- Reserve about 1 cup of pasta water before draining. This starchy water is liquid gold and will help the sauce cling to the pasta!
- Drain the pasta and set aside.
Step 2: Blacken the Chicken
- In a medium bowl, combine the chicken pieces with olive oil, Cajun seasoning, smoked paprika, garlic powder, cayenne pepper (if using), salt, and black pepper. Make sure the chicken is evenly coated.
- Heat a large skillet (cast iron is ideal for that authentic blackened flavor!) over medium-high heat.
- Add the seasoned chicken to the hot skillet in a single layer (don’t overcrowd the pan – you might need to cook in batches).
- Cook for about 3-4 minutes per side, until the chicken is cooked through and beautifully blackened. The internal temperature should reach 165°F (74°C).
- Remove the chicken from the skillet and set aside.
Step 3: Whip Up the Alfredo Sauce
- In the same skillet (don’t wipe it out – those chicken bits add flavor!), melt the butter over medium heat.
- Add the minced garlic and sauté for about 1 minute, until fragrant, being careful not to burn it.
- Pour in the heavy cream and bring to a simmer, stirring occasionally.
- Reduce the heat to low and simmer for about 5 minutes, allowing the sauce to thicken slightly.
- Gradually whisk in the grated Parmesan cheese until it’s fully melted and the sauce is smooth and creamy.
- Stir in the nutmeg, salt, and black pepper to taste.
- If the sauce is too thick, add a little of the reserved pasta water until it reaches your desired consistency.
Step 4: Combine and Conquer
- Add the cooked pasta to the skillet with the Alfredo sauce. Toss to coat the pasta evenly.
- Add the blackened Cajun chicken to the pasta and sauce. Gently toss everything together.
- If the pasta seems dry, add a splash more of the reserved pasta water.
Step 5: Serve and Savor
- Serve the Spicy Blackened Cajun Chicken Alfredo immediately.
- Garnish with chopped fresh parsley and extra grated Parmesan cheese, if desired.
- Get ready for a flavor explosion!
Tips and Tricks for Alfredo Awesomeness
- Don’t Overcook the Chicken: Overcooked chicken will be dry and tough. Use a meat thermometer to ensure it reaches the correct internal temperature.
- Freshly Grated Parmesan is Key: Pre-shredded Parmesan cheese often contains cellulose, which can prevent it from melting smoothly into the sauce. Freshly grated Parmesan will give you the creamiest, most flavorful Alfredo.
- Adjust the Spice Level: If you’re sensitive to spice, reduce the amount of cayenne pepper in the Cajun seasoning or omit it altogether. You can always add a pinch of red pepper flakes to your individual serving if you want a little extra kick.
- Make it Your Own: Feel free to add other vegetables to the pasta, such as sautéed bell peppers, onions, or mushrooms.
- Pasta Water is Your Friend: Seriously, don’t skip reserving the pasta water! It helps to create a silky, emulsified sauce that clings beautifully to the pasta.
Variations to Spice Things Up (Even More!)
- Shrimp, Anyone? Substitute the chicken with shrimp for a Spicy Blackened Cajun Shrimp Alfredo. Follow the same cooking instructions for the shrimp as you would for the chicken.
- Vegetarian Delight: Leave out the chicken altogether and add roasted vegetables like broccoli, cauliflower, and bell peppers for a vegetarian version.
- Cream Cheese Twist: For an extra creamy and tangy Alfredo sauce, stir in 2-4 ounces of softened cream cheese along with the Parmesan cheese.
- Add Some Greens: Spinach or kale can be stirred in during the last few minutes of cooking for added nutrients and a vibrant pop of color.
Cajun Seasoning: Store-Bought vs. Homemade
While store-bought Cajun seasoning is perfectly fine, making your own allows you to control the ingredients and customize the spice level to your liking. Plus, it’s super easy! The homemade Cajun seasoning recipe listed above is a great starting point, but feel free to adjust the ratios to suit your taste. For example, if you prefer a smokier flavor, add more smoked paprika. If you like it extra spicy, crank up the cayenne pepper.Serving Suggestions: Complete the Feast
This Spicy Blackened Cajun Chicken Alfredo is a complete meal on its own, but it pairs perfectly with a variety of side dishes. A simple green salad with a light vinaigrette provides a refreshing contrast to the richness of the pasta. Garlic bread or crusty rolls are also great for soaking up any extra sauce. For a more substantial meal, consider serving it with roasted asparagus or steamed green beans. And if you’re feeling fancy, a glass of crisp white wine complements the flavors beautifully.Other Pasta Dishes You’ll Love
