Melt the butter in a saucepan over medium-high heat. Add the garlic and cook until it is fragrant and becomes golden, about 1 minute.
Stir in the anchovies and the oil from the tin and continue to cook, stirring often, until the anchovies melt into the butter, about 5 minutes.
Transfer the sauce to a medium bowl. Serve with bread or raw vegetables on the side for dipping.
