Thoroughly pat duck legs dry with paper towels. Gently score the skin in a crosshatch pattern, avoiding the meat. Season generously on both sides with salt, black pepper, and a portion of the thyme sprigs.

Spread the sliced onions or turnips evenly in a roasting or baking dish. Add the smashed garlic cloves and whole thyme sprigs. Drizzle lightly with olive oil or duck fat if the duck legs are lean, then toss to coat evenly.

Preheat oven to 150°C. Arrange duck legs skin side up over the vegetable bed. Roast uncovered for 120–150 minutes, basting once or twice with rendered duck fat. Duck should become tender, and vegetables will caramelize in the juices.

Increase oven temperature to 220°C for the final 20–25 minutes. Roast until the duck skin is golden and crackling. Monitor closely to avoid burning.

Plate the caramelized onions or roasted turnips. Top each portion with a duck leg. Drizzle with pan juices and garnish with a fresh thyme sprig.
