Rub the chicken breasts with 1 tablespoon of Cajun seasoning, ensuring they are well-coated.
In a large skillet, heat olive oil over medium heat. Add the seasoned chicken breasts and cook for about 6-7 minutes on each side, or until cooked through. Remove from the skillet and let rest before slicing into strips.
While the chicken is cooking, bring a large pot of salted water to a boil. Add the fettuccine and cook according to package instructions until al dente. Drain the pasta and set aside.
In the same skillet used for the chicken, add the minced garlic and sauté for about 30 seconds until fragrant. Pour in the heavy cream and bring to a gentle simmer. Stir in the Parmesan cheese until melted and smooth, then add the remaining Cajun seasoning, sun-dried tomatoes, and baby spinach.
Add the cooked pasta to the skillet and toss to coat thoroughly with the Alfredo sauce. Incorporate the sliced chicken pieces and mix well until everything is heated through. Season with salt and pepper to taste.
Plate the Cajun chicken Alfredo pasta and garnish with chopped parsley for a pop of color.
Notes
Serve in deep bowls with additional grated Parmesan on top and a drizzle of olive oil for an elegant touch.
