Prepare the Chicken: Place the chicken breasts on a cutting board. Using a sharp knife, slice each breast in half horizontally to create two thinner cutlets. This ensures the chicken cooks thoroughly and efficiently. Season each side of the chicken cutlets with salt and pepper. Season both sides of the chicken cutlets with salt and pepper.
Coat the Chicken: In a shallow dish, combine the gluten-free bake mix (or almond flour) and the Parmesan cheese. Dredge each chicken cutlet in the mixture, pressing gently to adhere the coating to the chicken.
Cook the Chicken: Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Once hot, add the coated chicken cutlets to the skillet. Sauté for 3 to 4 minutes per side, or until they are golden brown and fully cooked. The internal temperature should hit 165°F (74°C). Once done, transfer the chicken from the skillet and let it rest.
Make the Garlic Butter Sauce: In the same skillet, reduce the heat to medium and add the unsalted butter. After the butter has melted, stir in the minced garlic and cook for approximately 1 minute, or until it becomes aromatic.
Create the Creamy Sauce: Slowly pour in the heavy cream, stirring constantly to combine. Bring the mixture to a gentle simmer, then stir in the freshly grated Parmesan cheese. Continue to stir until the cheese has melted and the sauce is smooth.
Season the Sauce: Add the dried Italian seasoning, chopped parsley, and lemon juice to the sauce. Stir well to incorporate.
Combine and Serve: Return the cooked chicken cutlets to the skillet, spooning the creamy garlic butter sauce over the top. Let the chicken cook in the sauce for an additional 2 to 3 minutes so it can absorb all the delicious flavors.
Garnish and Serve: Remove from heat and garnish with extra chopped parsley and a sprinkle of freshly grated Parmesan cheese if desired. Serve immediately with your favorite sides such as steamed vegetables, mashed potatoes, or pasta.
