01 - Pat chicken breasts dry using paper towels. Season evenly on both sides with salt and pepper, then lightly coat each breast in gluten-free flour or cornstarch, shaking off excess.
02 - Heat olive oil in a large skillet over medium-high heat. Place chicken breasts in skillet and cook for 4 to 5 minutes per side until golden brown and cooked through. Transfer cooked chicken to a plate and keep warm.
03 - Add minced garlic to the skillet and sauté for 30 seconds until fragrant, without browning.
04 - Pour in chicken broth, lemon juice, and zest. Bring mixture to a gentle simmer, scraping up any browned bits from skillet to incorporate into sauce.
05 - Stir in honey or maple syrup. Let sauce simmer and reduce by about one-third for 4 to 5 minutes.
06 - Place chicken breasts back in the sauce, spooning liquid over the top. Simmer for 3 to 4 minutes until chicken is heated through and sauce thickens slightly.
07 - Stir in butter until fully melted and sauce appears glossy.
08 - Top with chopped fresh parsley and lemon slices before serving.
