📝 About This Recipe

This quintessential French masterpiece balances the rich, succulent fat of roasted duck with a sophisticated 'gastrique'—a bittersweet sauce of caramelized sugar, vinegar, and fresh citrus. Originating from the royal courts of France and popularized in mid-century fine dining, this dish is a study in culinary equilibrium. Our version ensures a shatteringly crisp skin and a vibrant, velvet-smooth orange sauce that elevates poultry to an art form.

🥗 Ingredients

The Duck

  • 5-6 pounds Whole Pekin Duck (giblets removed, excess fat trimmed from cavity)
  • 2 tablespoons Kosher Salt (more for seasoning the cavity)
  • 1 teaspoon Black Pepper (freshly cracked)
  • 1 piece Orange (halved, for the cavity)
  • 4 sprigs Fresh Thyme

The Gastrique and Sauce

  • 1/3 cup Granulated Sugar
  • 1/4 cup White Wine Vinegar (high quality)
  • 1 cup Fresh Orange Juice (strained, about 3-4 oranges)
  • 1.5 cups Duck or Beef Stock (unsalted, high-quality gelatinous stock)
  • 2 tablespoons Grand Marnier (or Cointreau)
  • 1 tablespoon Orange Zest (julienned and blanched)
  • 2 tablespoons Unsalted Butter (cold, cubed)

For Garnish

  • 2 pieces Orange Segments (supremed (skinless segments))
  • 1 sprig Fresh Parsley (for color)

👨‍🍳 Instructions

  1. 1

    Preheat your oven to 350°F (175°C). Remove the duck from the refrigerator 45 minutes before cooking to bring it to room temperature.

  2. 2

    Pat the duck extremely dry with paper towels. Use a sharp skewer or the tip of a paring knife to prick the skin all over at an angle, being careful to only pierce the skin and fat, not the meat. This allows the fat to render out.

  3. 3

    Season the cavity generously with salt, pepper, the halved orange, and thyme sprigs. Truss the legs with kitchen twine and tuck the wing tips under the back.

  4. 4

    Place the duck breast-side up on a rack set inside a roasting pan. Rub the exterior with the 2 tablespoons of kosher salt. Roast for 1 hour.

  5. 5

    Carefully turn the duck onto its breast and roast for another 20 minutes. Finally, turn it back to breast-side up, increase the oven temperature to 425°F (220°C), and roast for 15-20 minutes until the skin is deep golden brown and crisp.

  6. 6

    While the duck roasts, prepare the gastrique. In a heavy-bottomed saucepan over medium heat, combine the sugar and a splash of water. Cook without stirring until it turns a deep amber caramel color.

  7. 7

    Carefully pour in the vinegar (it will steam and sputter). Stir until the hardened caramel dissolves into the liquid.

  8. 8

    Add the orange juice and the stock. Bring to a boil, then reduce heat to a simmer. Let the liquid reduce by half until it coats the back of a spoon, about 15-20 minutes.

  9. 9

    Stir in the Grand Marnier and the blanched orange zest. Simmer for 2 more minutes.

  10. 10

    Once the duck is done (internal temperature of 165°F in the thickest part of the thigh), remove it from the oven and let it rest on a cutting board for 15 minutes before carving.

  11. 11

    Finish the sauce: Remove the sauce from the heat and whisk in the cold butter one cube at a time. This creates a glossy, 'monte au beurre' finish. Season with salt and pepper to taste.

  12. 12

    Carve the duck by removing the legs and breasts. Slice the breast meat into thick medallions.

  13. 13

    Plate the duck, nap with the warm orange sauce, and garnish with fresh orange segments and parsley.

💡 Chef's Tips

Pricking the skin is the secret to non-greasy duck; do not skip this step. Blanching your orange zest in boiling water for 1 minute before adding it to the sauce removes any bitter pith flavor. If the sauce is too tart, add a teaspoon of honey; if too sweet, add a drop more vinegar. Always use a wire rack when roasting to ensure the heat circulates under the duck, preventing a soggy bottom. Save the rendered duck fat from the roasting pan—it is 'liquid gold' for roasting potatoes later.

🍽️ Serving Suggestions

Serve alongside Pommes Anna or buttery mashed potatoes to soak up the sauce. Pairs beautifully with honey-glazed roasted carrots or sautéed green beans with almonds. For wine, choose a high-acid red like a Pinot Noir from Burgundy or a slightly off-dry Riesling. A crisp green salad with a light vinaigrette helps cut through the richness of the meat. Sparkling cider is a wonderful non-alcoholic pairing that complements the fruit notes.
