Prep the chicken: Pat the chicken dry with paper towels. This helps you get a good sear.
Cut into even 1-inch pieces for quick, consistent cooking.
Season well: In a bowl, toss the chicken with salt, pepper, paprika, and garlic powder until evenly coated.
Heat the pan: Place a large skillet over medium-high heat. Add olive oil and 1 tablespoon of butter. Let the butter melt and foam slightly.
Sear in batches: Add about half the chicken in a single layer.
Don’t crowd the pan. Cook 3–4 minutes, undisturbed, until golden on one side. Flip and cook another 2–3 minutes, until just cooked through.
Transfer to a plate. Repeat with remaining chicken, adding a bit more oil if needed.
Make the garlic butter: Lower heat to medium. Add the remaining 2 tablespoons of butter to the skillet.
Stir in the minced garlic and cook 30–60 seconds, just until fragrant. Don’t brown the garlic.
Deglaze (optional but recommended): Add white wine or chicken broth to the pan. Scrape up the browned bits with a wooden spoon.
Let it simmer for 30–60 seconds to slightly reduce.
Toss it all together: Return the chicken and any juices to the pan. Add lemon juice, parsley, and a pinch of red pepper flakes if using. Toss to coat the chicken in the sauce.
Taste and adjust salt and pepper.
Serve hot: Plate immediately with extra parsley and lemon wedges. Great over rice, mashed potatoes, pasta, or with crusty bread.
