Before you begin:
Read through the recipe and prepare all ingredients and cookware in advance. Cooking times and results may vary depending on skillet size, heat level, and chicken thickness. Cook until the recommended doneness cues are met, adjusting time as needed for best results.
Season the chicken with salt and pepper and pat dry.
Mix Parmesan and panko and press onto all sides of the chicken.
Heat oil in a large skillet and sear the chicken for three to four minutes per side.
Lower the heat and sauté the garlic for one minute.
Add the cream, seasoning, and spinach. Stir well.
Add the remaining Parmesan and allow the sauce to thicken.
Cover and cook for eight to ten minutes, or until the chicken reaches 165°F.
Serve with the creamy garlic sauce spooned over the top.
