Generously season both sides of the chicken with Italian seasoning, salt, and pepper. Brush one side of each fillet with melted butter, ensuring the butter is not excessively hot.

Heat olive oil in a large skillet over medium-high heat. Sear chicken fillets in batches for 4–5 minutes per side until deeply golden and cooked through. Remove chicken from the skillet and set aside.

Return seared chicken fillets to the skillet. Spoon sauce over each piece, cover the skillet partially, and let the chicken reheat and absorb the flavors for about 10 minutes, ensuring it is thoroughly heated through.
