01 - Pat the chicken pieces dry with paper towels. Season thoroughly with salt, black pepper, and smoked paprika, ensuring even coating on all sides.
02 - Heat 1 tablespoon butter and olive oil in a large skillet over medium-high heat until butter melts and begins to shimmer.
03 - Add chicken in a single layer without overcrowding. Sear for 5-6 minutes, turning occasionally, until golden brown and cooked through to internal temperature of 165°F. Transfer to a plate and repeat with remaining chicken if cooking in batches.
04 - Reduce heat to medium. Add remaining 2 tablespoons butter to skillet. Once melted and foaming, stir in minced garlic and red pepper flakes. Sauté for 30 seconds until fragrant, being careful not to burn the garlic.
05 - Return seared chicken to the skillet. Toss thoroughly to coat each piece in the garlic butter sauce. Stir in lemon juice and chopped parsley until well combined.
06 - Serve immediately while hot, garnished with additional fresh parsley and lemon wedges on the side for squeezing.
