Slice the chicken into even pieces or lightly flatten so it cooks evenly. Season both sides with salt, pepper, and paprika.
Heat olive oil and a small amount of butter in a pan over medium-high heat. Add the chicken and cook undisturbed for a few minutes until golden. Flip and cook the other side until fully done but still juicy. Remove and set aside.
In the same pan, reduce heat slightly and add more butter. Once melted, add minced garlic and sauté for about 30 seconds until fragrant (do not burn). Add a splash of lemon juice if desired.
Return the chicken to the pan and toss in the garlic butter sauce. Simmer for a couple of minutes until the chicken absorbs the flavors and the sauce is glossy.
