Heat 1 tablespoon oil in a 10-inch skillet over medium heat. Add the beef; cook until well browned on both sides and it reaches your preferred doneness. An instant-read thermometer inserted into the center should read 130 degrees F (63 degrees C) for medium-rare, about 10 minutes. Remove the beef from the skillet.

Heat 1 tablespoon butter and the remaining 1 tablespoon oil in the same skillet. Add the mushrooms; cook, stirring occasionally, until tender, about 5 minutes. Add the shallot, garlic, and rosemary; cook until just fragrant, about 30 seconds. Stir in the concentrated broth, water, and the remaining 1 tablespoon butter until the butter melts. Remove from the heat.
