While the turkey pressure cooks, preheat the oven to 400°F. Mix the remaining seasoning mixture with the butter. When the turkey is ready, remove it from the pot and place it, skin-side up, on a rack set over a rimmed baking sheet. Brush the turkey skin with the seasoned butter. Roast the turkey for 10 to 15 minutes, until the skin is browned and the interior temperature reaches at least 155°F.
