Chicken Fillet in Spicy Garlic Parmesan Sauce: A Flavorful, Zesty Delight

Cook the chicken: Season the chicken fillets with salt and pepper on both sides. Heat the olive oil in a large skillet over medium heat. Once hot, add the chicken fillets and cook for 5-6 minutes per side, or until the chicken is golden brown and cooked through (internal temperature should reach 165°F/74°C). Remove the chicken from the skillet and set it aside.
Make the spicy garlic Parmesan sauce: In the same skillet, melt the butter over medium heat. Add the minced garlic and crushed red pepper flakes, and sauté for 1-2 minutes until the garlic is fragrant but not browned.
Add the liquids and cheese: Stir in the heavy cream, chicken broth, and Dijon mustard. Bring the mixture to a gentle simmer and cook for 3-4 minutes, allowing the sauce to thicken. Once the sauce has thickened, stir in the grated Parmesan cheese, and continue to cook for another 2-3 minutes until the cheese has melted and the sauce is smooth.
Combine the chicken and sauce: Return the cooked chicken fillets to the skillet, spooning the sauce over the top of the chicken. Let it simmer for an additional 2-3 minutes to heat the chicken through and allow the flavors to meld.
Serve: Transfer the chicken fillets to serving plates, generously spooning the sauce over the top. Garnish with chopped fresh parsley and extra grated Parmesan, if desired.
