Prep the chicken: Pat the chicken pieces dry with paper towels. Dry surfaces brown better.
Add salt, pepper, paprika, and garlic powder. Toss to coat evenly.
Optional light dredge: Sprinkle the flour over the chicken and toss again. This creates a thin crust that helps the sauce cling.
Skip if you’re gluten-free or prefer a lighter finish.
Heat the pan: Set a large skillet over medium-high heat. Add the olive oil and 1 tablespoon of the butter. When the butter foams and smells nutty, you’re ready to cook.
Sear in batches: Add half the chicken in a single layer.
Don’t crowd the pan. Cook 3–4 minutes until deeply golden on one side, flip, and cook 2–3 minutes more until just cooked through. Transfer to a plate.
Repeat with the remaining chicken.
Build the sauce: Reduce heat to medium-low. Add the remaining 2 tablespoons butter to the skillet. Stir in the minced garlic and cook 30–45 seconds until fragrant but not browned.
Add lemon elements: Stir in the lemon zest, 2 tablespoons lemon juice, and the red pepper flakes if using.
Scrape up any browned bits from the pan. Those bits are flavor gold.
Return the chicken: Add the chicken back to the skillet and toss to coat. Warm through for 1–2 minutes.
Taste and adjust with more lemon juice, salt, or pepper as needed.
Finish: Stir in the parsley. Remove from heat. Serve with extra lemon wedges.
