Prepare the chicken: Place chicken breasts between plastic wrap and pound to an even thickness using a meat mallet.
Season the chicken: Combine all spices and coat chicken evenly on both sides. Press seasoning into the meat for maximum flavor.
Cook the chicken: In a hot skillet with butter and olive oil, sear the chicken for 4–5 minutes per side until blackened and fully cooked. Let rest, then slice.
Make the Alfredo sauce: In the same skillet, melt butter and stir in cornstarch. Slowly add chicken broth and cream while whisking to avoid lumps.
Add the cheese: Stir in freshly grated Parmesan until the sauce becomes creamy and smooth. Adjust seasoning as needed.
Combine and serve: Add cooked fettuccine to the sauce, toss to coat, then top with sliced blackened chicken and fresh parsley.
Notes
This dish turned a cooking fail into a love story — creamy, spicy, and unforgettable. Let the cream come to room temperature before cooking to avoid sauce separation.
