01 - Season chicken breasts with salt and pepper. Dredge lightly in flour, shaking off excess.
02 - Heat olive oil and 1 tablespoon butter in a large skillet over medium-high heat. Add chicken breasts and cook for 5 to 6 minutes per side until golden and cooked through. Transfer to a plate and tent loosely with foil.
03 - Reduce heat to medium. Add remaining 2 tablespoons butter to the skillet and sauté garlic for 1 minute until fragrant.
04 - Stir in lemon zest, lemon juice, and chicken broth, scraping up any browned bits from the bottom of the pan. Simmer for 3 to 4 minutes.
05 - Return chicken and any accumulated juices to the skillet. Spoon sauce over each piece and simmer for 2 to 3 minutes. Garnish with fresh parsley and serve immediately with extra sauce spooned over the top.
