Narrative:
While on approach into pbi; we were at 7000 ft MSL and given a clearance to cross gullo at 3000 ft. As we started the descent; we hit turbulence; then rolled hard to the right. The autopilot disconnected. I took [the] controls and started to level the aircraft when a second wave hit us harder and pitched the plane down and rolled hard right to about 45-60 degrees wing down. I tried to level the aircraft but it wouldn't roll back level. I tried to climb above the wake turbulence. After using excessive control I got the plane to roll level and climbed back to 7000 ft from about 6600 ft. We lost about 400 feet during the encounter. We asked ATC and they said we were 7 miles behind a 737-800. We took a vector out of the turbulence area and returned to another attempt to the approach.
