For the pork, heat a large pan to medium-high. Once it starts to smoke, add enough oil to coat the bottom of the pan. Place the pork into the pan, Since we seasoned them early, there is no need to season them now.
Cook the pork until it has a nice sear all around, about two minutes per side for a total of 8 minutes. Add 60 g of butter with one smashed garlic clove and a large sprig of thyme and baste the pork. Basting the pork not only helps develop a nice color to the meat, but it helps impart more flavor.
Place the pork on a sheet tray with a wire rack then top with the butter, thyme, and garlic. Place the pork into a 300 F oven until you hit 135 F internal then rest in a warm spot.
To reheat the food, place the butternut squash in the water bath, then place on a tray once warmed.
Heat the puree and the sauce on the stove. Place the glazed brussel sprouts and plate under a low broiler.
While everything is heating up, remove the string from the pork and portion.
