In the days after Thanksgiving, keep it simple: These turkey potpies combine the supper's surplus with on-hand items for an outstanding Thanksgiving encore that everyone will love.
Preheat oven to 400 degrees, with rack in upper third. In a large skillet, cook bacon over medium heat, stirring occasionally, until crisp, 8 to 10 minutes; with a slotted spoon, transfer to paper towels to drain. Add leeks, mushrooms, and thyme to skillet and season with salt and pepper. Cook, stirring often, until vegetables are golden brown and softened, about 12 minutes. Sprinkle flour over vegetables and cook, stirring, until flour is pale golden, about 2 minutes. Stir in broth and simmer until thickened, 4 minutes. Stir in turkey, peas, and bacon. Season with salt and pepper.
Transfer turkey mixture to eight broilerproof 8-ounce ramekins or a 2-quart baking dish; set on a rimmed baking sheet. Spread potatoes over turkey mixture. Bake until filling is bubbling and potatoes are golden in spots, 20 minutes.
Heat broiler with rack in top position. Broil until potatoes are evenly golden, 2 to 3 minutes. Let cool 10 minutes.
Turn two of the season's most common leftovers -- turkey and mashed potatoes. You can swap onions for leeks or use parsley in place of thyme.
