The Best Chicken Parmesan is a classic Italian favorite, breaded and baked with an easy marinara sauce, Parmesan and mozzarella cheese in just 30 minutes!
Preheat an oven to 375 degrees and spray a baking sheet with cooking spray.
Put the chicken breasts between two pieces of saran wrap or parchment paper and using a rolling pin or flat kitchen mallet flatten it to 1/2 inch thickness then season them with salt and pepper.
Add the olive oil and butter to a cast iron skillet on medium high heat and cook the chicken for 3-4 minutes on each side until golden brown (it'll be raw inside still).
Add the chicken to a baking sheet, add the marinara sauce on top and finally top with the shredded mozzarella and cook for 18-20 minutes.
