Follow these clear and simple steps to whip up your Spicy Feta Chicken Alfredo:

1. Cook the Pasta: Begin by boiling a large pot of salted water. Add the fettuccine and cook according to package instructions until al dente. Drain and set aside.

2. Prepare the Chicken: While the pasta is cooking, season the chicken breasts with salt and pepper.

3. Sauté the Chicken: In a large skillet, heat olive oil over medium heat. Add the chicken and cook for 6-7 minutes on each side, or until fully cooked and golden brown. Remove from the skillet and let rest.

4. Make the Alfredo Sauce: In the same skillet, add the minced garlic and red pepper flakes. Sauté for about 1 minute until fragrant.

5. Add Cream and Cheese: Pour in the heavy cream and bring to a simmer. Stir in the Parmesan cheese and feta cheese until melted and smooth.

6. Slice the Chicken: While the sauce is simmering, slice the cooked chicken into strips.

7. Combine Ingredients: Add the drained pasta to the skillet with the sauce, tossing to coat evenly. Finally, fold in the sliced chicken.

8. Serve Hot: Once everything is well combined and heated through, remove from heat and garnish with fresh herbs.

By following these steps, you create a stunning meal that is as pleasing to the eye as it is to the taste buds.
