I start by seasoning the chicken breasts with salt and pepper. Then, I heat olive oil in a skillet and sear each side until golden brown. This locks in the juices and gives the chicken a nice crust.
Once the chicken is removed, I sauté garlic, onions, and bell peppers in the same skillet. This picks up the flavors left by the chicken, giving the sauce a rich base.
I whisk together heavy cream, chicken broth, tomato paste, chipotle peppers, smoked paprika, and red pepper flakes. Then I pour it into the skillet with vegetables and let it simmer. The sauce thickens while absorbing all the smoky, spicy flavors.
While the sauce simmers, I boil fettuccine pasta according to package instructions until al dente. I always save a cup of pasta water in case the sauce needs loosening.
I slice the cooked chicken and add it back to the skillet. Then, I toss the pasta in the sauce until fully coated. A sprinkle of Parmesan and parsley finishes the dish beautifully.
