🥗 Ingredients

The Cure

  • 4 pieces Duck Legs (approx. 8-10 oz each, skin-on)
  • 2 tablespoons Coarse Sea Salt (do not use table salt)
  • 4 sprigs Fresh Thyme (bruised to release oils)
  • 4 pieces Garlic Cloves (smashed)
  • 1 teaspoon Black Peppercorns (cracked)

The Confit

  • 3-4 cups Rendered Duck Fat (enough to fully submerge the legs)
  • 2 pieces Bay Leaves (dried)
  • 1 whole Star Anise (adds a subtle depth without being sweet)

The Olive Braise (Aux Olives)

  • 1 cup Castelvetrano Olives (pitted and halved)
  • 2 pieces Shallots (thinly sliced)
  • 1/4 cup Dry White Wine (use a dry Sauvignon Blanc or Pinot Grigio)
  • 1/2 cup Chicken Bone Broth (unfiltered and high protein)
  • 1 teaspoon Lemon Zest (finely grated)
  • 2 tablespoons Fresh Parsley (finely chopped for garnish)

👨‍🍳 Instructions

  1. 1

    Begin by preparing the cure. Rub the duck legs thoroughly with sea salt, smashed garlic, cracked pepper, and thyme. Place them in a glass dish, cover tightly, and refrigerate for at least 12 hours (ideally 24) to season the meat and draw out moisture.

  2. 2

    Preheat your oven to 225°F (110°C). This low temperature is crucial for the 'confit' process to ensure the fat doesn't boil, but rather poaches the meat.

  3. 3

    Rinse the duck legs under cold water to remove the excess salt and aromatics. Pat them very dry with paper towels; moisture is the enemy of a good confit.

  4. 4

    Place the duck legs snugly in a small, heavy-bottomed ovenproof pot or Dutch oven. Melt the duck fat and pour it over the legs until they are completely submerged.

  5. 5

    Add the bay leaves and star anise to the fat. Cover the pot with a lid and place in the oven. Cook for 2.5 to 3 hours, or until the meat is incredibly tender and starting to pull away from the bone.

  6. 6

    Carefully remove the duck legs from the hot fat and place them on a wire rack set over a baking sheet. Strain the fat and save it for future use (it lasts months in the fridge!).

  7. 7

    Increase the oven temperature to 425°F (220°C). Place the duck legs back in the oven for 10-15 minutes until the skin is mahogany brown and shatter-crisp.

  8. 8

    While the skin crisps, prepare the olive sauce. In a small skillet, sauté the sliced shallots in 1 tablespoon of the duck fat over medium heat until translucent.

  9. 9

    Deglaze the pan with the white wine, scraping up any browned bits. Let the wine reduce by half.

  10. 10

    Add the bone broth and the halved olives. Simmer for 5 minutes until the sauce thickens slightly and the olives are warmed through.

  11. 11

    Stir in the lemon zest and fresh parsley at the very last second to keep the flavors vibrant.

  12. 12

    To serve, spoon a generous amount of the olive and shallot mixture onto a warm plate, place a crisp duck leg on top, and drizzle with a little extra sauce.

💡 Chef's Tips

Always pat the duck skin bone-dry before the final crisping stage to ensure maximum crunch. If you don't have enough duck fat, you can supplement with high-quality lard or clarified butter (ghee). Don't discard the leftover duck fat; it is liquid gold for roasting keto-friendly vegetables like radishes or cauliflower. For an even deeper flavor, add a few strips of orange peel to the fat during the slow-cooking process. Make sure the olives are Castelvetrano variety; their buttery, mild flavor is superior for this specific French preparation.

🍽️ Serving Suggestions

Serve alongside a bed of buttery mashed cauliflower or sautéed garlic spinach. Pair with a glass of crisp, chilled Sancerre or a light-bodied Pinot Noir. A simple arugula salad with a lemon-mustard vinaigrette cuts through the richness beautifully. For a complete French experience, serve with a side of roasted radishes finished with sea salt.
