01 - Season chicken breasts with salt and pepper. Dredge lightly in flour, shaking off any excess.
02 - In a large skillet over medium-high heat, add olive oil and 1 tablespoon butter. Once hot, add chicken breasts and cook for 5–6 minutes per side until golden and cooked through. Transfer to a plate and tent with foil.
03 - Lower 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 the browned bits from the bottom of the pan. Simmer for 3–4 minutes.
05 - Return chicken and any accumulated juices to the skillet. Spoon sauce over the chicken and simmer for 2–3 minutes.
06 - Garnish with fresh parsley and serve immediately, spooning extra sauce over each piece.
