- Bring a saucepan of water to boil. Salt and then add in sweet potatoes. Cook until tender, 12 to 15 minutes. Drain and let them rest for ~5 minutes so that the liquid steams out.
- Preheat oven to 425F (218C) degrees.
- Heat a skillet or oven-safe pan over medium-high heat. Add pork tenderloin (reserve marinade) and sear on each side for 3 minutes until golden. Pour the rest of the marinade into skillet and cover loosely with foil.
- Cook for 12 to 16 minutes in the oven or until pork reaches 145F (63C) degrees. Last time we did pork tenderloin, there was quite a range in cooking time. Clearly the thicker your tenderloin, the longer it will take and the more you cook and get to know your oven, the more accurate you'll get.
- While pork is cooking, use a masher to mash sweet potatoes with milk and butter until you get the texture you want. Season to taste with salt and pepper. If you want them even sweeter, add your preferred sweetener (maple syrup would be great in this).
- Once pork is done, remove from skillet and set aside to rest. You can keep it covered in foil. Return skillet to medium-heat. Pour in thickener and stir and scrape up any bits that may have formed in the pan. Slice pork and drizzle with sauce. Enjoy over mashed sweet potatoes.
