Heat the olive oil over medium-high heat in an oven safe skillet. Brown pork tenderloin on all sides.
Place the skillet in the oven and cook for 20-25 minutes or until the pork registers 155-160 degrees. Remove from the oven, tent with foil to keep warm, and rest for while you prepare the sauce (about 10 min).
Over medium-low heat add wine to skillet to deglaze. Scrape the cooked bits from the skillet and whisk the cream and chopped garlic. Allow the sauce to slightly simmer and thicken for about 5 minutes (the sauce should be thick enough to heavily coat a spoon).
Slice pork tenderloin and spoon sauce over the top. Serve immediately.
