How to Make Cajun Chicken Alfredo
Step 1: Season the Chicken
Pat the chicken breasts dry with paper towels. Coat both sides evenly with Cajun seasoning, making sure every part of the chicken is covered with the spice blend.
Step 2: Cook the Chicken
Heat olive oil and butter in a large skillet over medium-high heat. Cook the chicken for about 5–7 minutes per side until golden brown and fully cooked.
Step 3: Let the Chicken Rest
Transfer the cooked chicken to a plate and allow it to rest for a few minutes. This helps the juices stay inside the meat, keeping it tender and flavorful.
Step 4: Slice the Chicken
Once rested, slice the chicken into thin strips. Set aside while preparing the Alfredo sauce and pasta.
Step 5: Cook the Pasta
Bring a large pot of salted water to a boil. Cook the fettuccine according to the package instructions until al dente, then reserve some pasta water before draining.
Step 6: Prepare the Alfredo Sauce Base
In a large skillet, melt butter over medium heat. Add minced garlic and cook for about one minute until fragrant without allowing it to brown.
Step 7: Add Cream and Milk
Slowly pour the heavy cream and milk into the skillet. Stir continuously and allow the mixture to warm gently while developing a rich, smooth texture.
Step 8: Add Parmesan Cheese
Gradually add the grated Parmesan cheese while stirring constantly. Continue mixing until the cheese melts completely and the sauce becomes creamy.
Step 9: Season the Sauce
Add black pepper and salt to taste. Stir thoroughly so the seasonings are evenly distributed throughout the Alfredo sauce.
Step 10: Combine Pasta and Sauce
Add the cooked fettuccine directly to the sauce. Toss gently until every strand of pasta is coated with the creamy Alfredo mixture.
Step 11: Add Cajun Chicken
Arrange the sliced Cajun chicken over the pasta or mix it throughout the dish. This ensures every serving gets plenty of flavorful chicken.
Top with fresh parsley, extra Parmesan cheese, and red pepper flakes if desired. Serve immediately while hot and creamy.
