Slice the chicken breasts in half lengthwise using a sharp knife to create 4 smaller cutlets. Of if using four small chicken breasts, you may want to place each between two pieces of plastic wrap and pound the thick end with a meat mallet to flatten them slightly for even cooking. Sprinkle the chicken breasts evenly with the salt and pepper.
2 large chicken breasts, 2 teaspoons coarse kosher salt, 1/2 teaspoon freshly ground black pepper
Place the dredging flour in a shallow plate or dish, then dip each chicken breast in the flour, turning to coat on both sides and shaking off any excess. Discard any unused flour.
1/3 cup all-purpose flour
Heat 1 tablespoon each of the olive oil and butter in a large skillet over medium-high heat. Once the pan is hot and the butter has melted, add the chicken and let it sear without moving for 2-4 minutes until golden brown on the bottom. Flip and cook on the other side for another 2-4 minutes. Remove the chicken from the pan and set aside to keep warm. The chicken does not need to be fully cooked through at this point.
2 Tablespoons olive oil, 2 Tablespoons salted butter
Reduce the heat to medium or medium-low and add the remaining oil and butter. Once the butter has melted and the oil is hot, add the whole garlic cloves. Cook for 3-5 minutes, stirring frequently, until nicely browned.
2 whole heads garlic
Add the chicken broth, lemon juice, garlic powder, and onion powder. Bring to a simmer and let it bubble for 4-5 minutes until the liquid has reduced by half.
1 cup chicken broth, 1 teaspoon lemon juice, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder
Stir in the heavy cream and parmesan cheese, then nestle the seared chicken breasts back into the pan, spooning some of the sauce over the top of the chicken. Continue to simmer for another 5 minutes until the sauce has reduced and thickened slightly and the chicken is cooked through to 165°F when tested with a digital meat thermometer.
1 cup heavy cream, 1/2 cup freshly grated Parmesan cheese
Serve sprinkled with the freshly chopped parsley, if desired. It's excellent on its own or with mashed potatoes or pasta and green veggies like asparagus, green beans, or broccoli.
