Prep the chicken: Pat the chicken dry with paper towels.
Dry chicken browns better. Toss it in a bowl with 1 teaspoon salt, pepper, paprika, and garlic powder. For a lightly crisp exterior, sprinkle in cornstarch and toss again.
Heat the pan: Set a large skillet over medium-high heat.
Add the olive oil and 1 tablespoon of butter. When the butter foams and just starts to brown, 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 without moving, until golden on the bottom. Flip and cook another 2–3 minutes until just cooked through. Transfer to a plate.
Repeat with remaining chicken, adding a touch more oil if needed.
Make the garlic butter: Reduce heat to medium. Add remaining 2 tablespoons butter to the empty pan. Stir in the minced garlic and cook 30–45 seconds until fragrant.
Don’t let it brown.
Deglaze and season: Squeeze in the lemon juice and scrape up the browned bits from the pan with a wooden spoon. Add Italian seasoning or thyme if using. Taste and adjust salt.
Coat the chicken: Return all chicken (and any juices) to the pan.
Toss to coat in the garlic butter for 30–60 seconds. Sprinkle with parsley.
Serve: Plate immediately with lemon wedges. Add a final pinch of salt and pepper if needed.
