Pan-Roasted Bistro Duck Legs with French Lentils, Caramelized Fennel & Blood Orange Jus

Instructions

1. 1

   Preheat your oven to 375°F (190°C). Prick the skin of 2 legs bone-in, skin-on fresh duck legs all over with the tip of a paring knife at a shallow angle, being careful not to pierce into the meat. Season both sides generously with 1 tsp kosher salt and 1/4 tsp freshly cracked black pepper.

   5 min

   Tip: Pricking the skin allows the thick layer of fat underneath to render completely, ensuring golden, crackling bistro skin without drying out the meat.

2. 2

   Place the duck legs skin-side down in a cold, dry 10- or 12-inch ovenproof cast-iron skillet. Turn the heat to medium-low and let the fat render undisturbed for 15 minutes, listening for a gentle sizzle, until the skin turns a deep, crisp mahogany.

   15 min

   Tip: Starting in a cold pan is the golden rule of French duck cookery—it coaxing out maximum liquid gold fat without scorching.

3. 3

   While the duck skin renders, combine 3/4 cup French green lentils (Puy lentils), 2 cups low-sodium chicken stock or water, 3 sprigs fresh thyme sprigs, 1 fresh bay leaf, and 1/4 tsp kosher salt in a small saucepan. Bring to a boil over medium-high heat, then lower the heat to gentle simmer, cover partially, and cook until tender to the bite but holding their shape, about 25 minutes.

   25 min

   Tip: Do not boil lentils violently or their tender skins will split. Puy lentils maintain an incomparable peppery, mineral bite.

4. 4

   Once the duck skin is deeply bronzed and crisp, flip the duck legs skin-side up in the skillet. Spoon a tablespoon of the rendered pan fat over each leg, then immediately transfer the entire skillet into the preheated 375°F (190°C) oven to pan-roast until the meat is fork-tender and registers 175°F to 180°F at the thickest part, about 35 minutes.

   35 min

   Tip: Pan-roasting in the oven cooks the legs through uniformly while maintaining that crackly, shatteringly crisp skin.

5. 5

   When the lentils are tender, remove from heat, drain any excess liquid, discard the bay leaf and thyme stems, and keep warm. While the duck finishes roasting, prep your aromatics: finely slice 1 small fennel bulb, thinly slice 2 medium shallots, and shave 2 cloves garlic cloves.

   10 min

   Tip: Save the tender feathery fennel fronds for a light, anise-scented garnish right at the table.

6. 6

   Remove the duck skillet from the oven and carefully transfer the duck legs to a warm cutting board to rest for 8 minutes. Pour all the rendered duck fat from the skillet into a heatproof jar (save this liquid gold for roasted potatoes later!), leaving behind about 2 tablespoons in the skillet. Return skillet to medium heat and add 1 small fennel bulb and 2 medium shallots with 1/4 tsp kosher salt and 1/4 tsp freshly cracked black pepper. Sauté until the fennel is caramelized and tender, about 6 minutes, then stir in 2 cloves garlic cloves for 1 minute until fragrant.

   7 min

   Tip: The caramelized duck fat fond left on the bottom of the pan gives the fennel an unimaginable savory depth.

7. 7

   Fold the warm, cooked lentils directly into the skillet with the caramelized fennel along with 2 tbsp fresh flat-leaf parsley. Toss everything together for 1 minute to absorb the pan juices, taste and adjust seasoning with a pinch of salt if needed, then spoon the lentil mixture onto two warm serving plates.

   2 min

   Tip: Warming the plates keeps the lentils and roasted duck piping hot at the table.

8. 8

   Set the empty skillet back over medium heat. Pour in 1/4 cup dry white vermouth and scrape up any caramelized bits with a wooden spoon, simmering for 1 minute until reduced by half. Pour in 1/2 cup freshly squeezed blood orange juice, 1 tsp blood orange zest, 1 tsp Dijon mustard, and leaves stripped from 2 sprigs fresh thyme sprigs. Simmer rapidly until glossy and reduced to about 3 tablespoons, about 3 minutes. Turn off the heat and swirl in 2 tbsp cold unsalted French butter one piece at a time until emulsified and glossy.

   5 min

   Tip: Taking the pan off the heat before swirling in cold butter prevents the sauce from breaking, giving you a velvety, bistro-standard pan jus.

9. 9

   Nestle one rested duck leg atop the bed of warm lentils on each plate. Spoon the glossy blood orange pan jus generously around the duck and lentils. Scatter with reserved fennel fronds and 1/4 tsp flaky sea salt over the crispy duck skin. Serve immediately.

   2 min

   Tip: Pour the sauce around the duck leg rather than directly over the skin to preserve every bit of that hard-earned crispness.
