In a large pot of salted boiling water, cook the fettuccine according to the package instructions until al dente. Drain and set aside.
While the pasta cooks, rub the chicken breasts with Cajun seasoning, ensuring they’re well-coated on both sides.
In a large skillet, heat olive oil over medium heat. Add the seasoned chicken and cook for about 5-7 minutes per side, or until the internal temperature reaches 165°F (75°C) and the chicken is golden brown. Remove from the skillet and allow to rest before slicing.
In the same skillet, add the minced garlic and sauté for about 1 minute until fragrant. Pour in the heavy cream, stirring to combine. Allow it to simmer for 2-3 minutes.
Gradually add the grated Parmesan cheese to the cream, stirring continuously until melted and the sauce thickens. Season with black pepper and salt to taste.
Add the cooked fettuccine to the skillet and toss to coat in the creamy sauce. If needed, add a little pasta water to achieve your desired consistency.
Slice the cooked chicken breast and arrange it on top of the fettuccine Alfredo. Garnish with chopped parsley for a fresh touch.
Notes
Adjust the spice level by varying the amount of Cajun seasoning.
