Prepare the Chicken: Pat the chicken dry with paper towels. Season both sides with salt, pepper, paprika, and garlic powder.
Sear the Chicken: Heat olive oil in a large skillet over medium heat. Add the chicken and sear for 4-5 minutes per side, or until golden brown and cooked through (internal temp of 165°F/75°C). Remove from the pan and set aside.
Make the Garlic Butter Sauce: In the same skillet, reduce heat to low and melt the butter. Add minced garlic and red pepper flakes (if using), cooking for 30 seconds until fragrant.
Deglaze the Pan: Pour in the chicken broth (or white wine) and lemon juice, stirring to scrape up any browned bits from the pan. Let simmer for 2-3 minutes.
Combine Everything: Return the chicken to the pan, spooning the sauce over the top. Let cook for another 1-2 minutes until the flavors meld together.
Garnish & Serve: Sprinkle with fresh parsley and serve hot with mashed potatoes, rice, or crusty bread to soak up the sauce.
