- Olive Oil: For browning the chicken and creating that mouthwatering crust.

- Different Protein: Swap chicken for shrimp, salmon, or even tofu for a pescatarian or vegetarian take.
- Extra Spice: Add a pinch of cayenne pepper, or use a spicier Cajun seasoning for more heat.
- Gluten-Free: Use gluten-free pasta—you won’t miss a beat.
How to Make Cajun Chicken Alfredo
Step 1: Cook the Pasta
Bring a big pot of salted water to a boil. Drop in your fettucine and cook until just al dente, following the package instructions. Save half a cup of that starchy pasta water before draining—the key to silky sauce later!
Step 2: Season and Cook the Chicken
While the pasta cooks, pat your chicken pieces dry and coat them generously with Cajun seasoning, salt, and pepper. Heat olive oil in a large skillet over medium heat, then cook the chicken for 3–4 minutes per side. You’re looking for that perfect golden crust and juicy middle. Set aside and keep warm.
Step 3: Make the Alfredo Sauce
Lower the skillet heat to medium and add the butter. Sauté minced garlic until fragrant (about 1 minute), then toss in the cream cheese, stirring until perfectly smooth. Slowly pour in heavy cream, stirring constantly, and bring everything to a gentle simmer.
Step 4: Melt in the Cheese
Once the cream warms up, add the grated Parmesan, stirring until your sauce is luscious, thick, and creamy. Taste and adjust salt and pepper as needed.
Step 5: Combine and Serve
Tumble your drained pasta right into the sauce, tossing gently to coat. If the sauce gets too thick, splash in a little reserved pasta water until you love the texture. Slice your cooked chicken and arrange on top. Finish with parsley and extra Parmesan. Dive in while it’s piping hot!
Pro Tips for Making the Recipe
- Don’t Overcook the Chicken: Remove it as soon as it’s done for maximum juiciness.
- Use Fresh Parmesan: Pre-grated cheese doesn’t melt as well—grate a block yourself for best results.
- Save Your Pasta Water: It’s the secret to bringing any Alfredo sauce to glossy, restaurant-quality consistency.
- Control the Spice: Start with less Cajun seasoning and add to taste—you can always add more, but you can’t take it away!
- Work Quickly: Alfredo sauce is best enjoyed immediately, while the sauce is glossy and the pasta perfectly coated.
How to Serve
Pile generous portions of Cajun Chicken Alfredo onto warm plates or shallow bowls. Garnish with a flurry of fresh parsley and a little extra Parmesan for an irresistible finish. This is a complete meal on its own, but a crisp green salad or some garlicky bread never hurt anyone. If you’re hosting, consider pairing with a light Chardonnay or even a sparkling lemonade to balance the richness.
Make Ahead and Storage
Storing Leftovers
Cool leftovers quickly and store them in an airtight container in the fridge. They’ll stay delicious for up to 3 days.
Freezing
Alfredo sauce doesn’t always freeze gracefully, as dairy can separate. If you do freeze, thaw slowly in the fridge and reheat gently—but for best flavor and texture, enjoy fresh or refrigerated.
Reheating
Reheat over low heat on the stovetop or in the microwave. Add a splash of milk or cream to loosen the sauce if needed, and stir frequently until heated through.
FAQs
-
Can I use pre-cooked or rotisserie chicken?
Absolutely! Just toss the cooked, sliced chicken with Cajun seasoning and brown quickly in the skillet to let those flavors bloom, then proceed as usual.
-
Is there a way to make this healthier?
You can lighten things up by using reduced-fat cream cheese and swapping heavy cream for evaporated milk or half-and-half. The sauce will be a little less rich but still really enjoyable.
-
Can I make this recipe without cream cheese?
Cream cheese adds unique silkiness, but you can use extra heavy cream and a bit more Parmesan. Simmer the sauce a touch longer to reach your desired thickness.
-
What’s the best way to keep the sauce from getting clumpy?
Use room-temperature cream cheese and add Parmesan gradually, stirring constantly over gentle heat. Don’t crank the heat too high or you risk separation.
Final Thoughts
Cajun Chicken Alfredo truly checks every box—fast, flavorful, and a real comfort. The recipe is simple enough for any night, but impressive enough to share. Don’t be surprised if this one ends up in regular rotation (and requested by name!). Whip it up, put your own spin on it if you like, and enjoy every creamy, spicy, soul-satisfying bite.

Ingredients
Chicken and Pasta
- 8 ounces fettuccine pasta
- 1 pound boneless, skinless chicken tenderloins, breasts, or thighs
- 2 teaspoons Cajun seasoning (adjust to taste)
- 1/2 teaspoon kosher salt
- 1/4 teaspoon ground black pepper
- 1 tablespoon olive oil
Alfredo Sauce
- 2 tablespoons unsalted butter
- 3 garlic cloves, minced
- 8 ounces cream cheese, cut into small cubes
- 1 cup heavy cream
- 1 cup freshly grated Parmesan cheese
To Serve
- Fresh parsley, chopped (for garnish)
- Extra Parmesan cheese (for garnish)
Instructions
- Cook the Pasta: Bring a large pot of salted water to a boil. Add the fettuccine pasta and cook according to the package instructions until al dente. Reserve ½ cup of pasta water before draining. Set the cooked pasta aside.
- Season and Cook the Chicken: While the pasta cooks, season the chicken with Cajun seasoning, salt, and pepper. Heat olive oil in a large skillet over medium heat and add the chicken. Cook for 3–4 minutes per side, or until the chicken is golden brown and cooked through. Transfer the chicken from the skillet and keep warm.
- Make the Alfredo Sauce: In the same skillet (reduce heat to medium), melt the butter. Add the minced garlic and sauté for about 1 minute until fragrant. Add the cream cheese and stir until it’s melted and smooth.
- Finish the Sauce: Gradually pour in the heavy cream, stirring constantly to combine. Bring the mixture to a gentle simmer. Add the grated Parmesan cheese and stir until the sauce is creamy and fully incorporated. Season with extra salt and pepper as needed.
- Combine Pasta and Sauce: Add the cooked fettuccine to the skillet. Toss until the pasta is fully coated in the Alfredo sauce. If the sauce is too thick, add a little reserved pasta water to reach your desired consistency.
- Assemble and Serve: Slice the cooked chicken if desired. Place the chicken on top of the sauced pasta. Garnish with fresh parsley and extra Parmesan cheese. Serve warm and enjoy!
Notes
- Adjust the amount of Cajun seasoning to make the dish more or less spicy.
