Remove silver skin from pork tenderloin. Sprinkle with half each of the salt and pepper.

In a large ovenproof skillet, heat oil over medium-high heat. Sear tenderloin on all sides; remove from heat.

Preheat oven to 400ºF (200ºC).

Whisk together maple syrup, mustard, thyme and remaining salt and pepper until smooth. Set half of the sauce aside. Pour remaining sauce over pork tenderloin in skillet and turn to coat well.

Place pork tenderloin in oven for about 18 minutes, basting and turning occasionally with remaining sauce. Roast until meat thermometer registers 155ºF (68ºC). Transfer to cutting board and let rest for 5 minutes. Slice thinly to serve.
