Narrative:

While at cruise at FL370 we noticed a rapid decrease in oil quantity in the left engine. As in 10-9-8-7-6 and so on. In less than 60 seconds the engine was out of oil. First officer was flying and I told her to turn back to ZZZ. She declared an emergency; flew the aircraft; and worked the radios. I worked the QRH procedures and shut down the left engine. I then briefed the flight attendants and passenger. The entire descent was nothing more than a glide from FL370 with speedbrakes out as we were right over ZZZ. I briefed the first officer on 1 engine approach procedures and worked the normal checklist and returned to the radios. In less than 15 mins we had landed normally (overweight by 1000 pounds) and safely with fire rescue shadowing us. ATC and fire rescue did an excellent job. The flight attendants did a superb job preparing the cabin and calming the passenger. I was most impressed with first officer's performance as she did a flawless job of flying the aircraft and working the emergency.
