Bright lemon, melted butter, tender chicken, sautéed zucchini. A low carb dinner that comes together in one pan in 20 minutes — weeknight perfection.
Pat chicken breasts dry and cut in half horizontally for quicker, even cooking. Season both sides with kosher salt, black pepper, and dried thyme.
Heat olive oil and 2 tbsp butter over medium-high heat in a large skillet. When the butter foams, add chicken pieces; cook undisturbed for 4 minutes until golden.
Flip chicken, reduce heat to medium, and cook 3–4 more minutes until cooked through and juices run clear. Remove chicken to a plate; tent with foil to keep warm.
Add remaining 1 tbsp butter to pan. Stir in minced garlic, sauté for 30 seconds until fragrant, then add sliced zucchini. Cook for 2–3 minutes over medium-high heat until zucchini is crisp-tender but bright.
Return chicken to skillet. Squeeze lemon juice over all, sprinkle with chopped parsley, and spoon butter sauce over chicken and zucchini. Serve hot immediately.
