Pat the chicken dry with paper towels and have all ingredients measured and ready before you begin.
Prepare the chicken: Slice into even pieces or lightly flatten. Season both sides with salt, pepper, and paprika.
Sear the chicken: Heat olive oil and a small amount of butter in a pan over medium-high heat. Cook chicken undisturbed for a few minutes until golden. Flip and cook until done. Remove and set aside.
Make the garlic butter sauce: In the same pan, reduce heat and add remaining butter. Once melted, add minced garlic and sauté 30 seconds until fragrant. Add lemon juice if desired.
Combine: Return chicken to the pan and toss in the garlic butter sauce. Simmer for a couple of minutes until coated and glossy.
