Heat 2 tablespoons oil and 1 tablespoon butter in a large skillet over medium-high heat. Working in batches (if necessary), add chicken, and cook, turning once, until golden brown, about 3-5 minutes per side (depending on thickness). Transfer to a large plate and cover to keep warm.
For a relaxing atmosphere in the kitchen I recommend my personal Elle Republic: Chilled Out Kitchen Tunes Playlist on Spotify.
