Keto Dinner

Duck Confit

Making duck confit at home feels like a true kitchen triumph. With just a handful of ingredients and patience, you get incredibly rich, fall-apart-tender duck legs that fit perfectly into a keto lifestyle. The slow-cooking process renders the fat beautifully, leaving you with a gourmet meal that’s surprisingly simple to prepare. I often make a batch to have on hand for quick, impressive dinners.

Duck Confit

Ingredients

  • uncooked Peking duck legs
  • tablespoon kosher salt
  • lemon, zested and thinly sliced
  • cloves garlic, crushed
  • tablespoon whole allspice berries
  • tablespoon juniper berries
  • sprigs fresh thyme
  • cups rendered duck fat

Instructions

  1. Step 1

    Start by seasoning the duck legs evenly with kosher salt on both sides. Place them in a large resealable bag with lemon zest, slices, crushed garlic, allspice, juniper berries, and fresh thyme. Seal and gently massage so all aromatics coat the legs, then refrigerate for 24 hours. The next day, preheat your oven to 200°F. Remove the legs from the marinade, rinse off the seasonings, and pat very dry. Scatter the bag’s contents into an oven-safe dish just large enough to hold the legs in one layer, then arrange the duck skin-side down. Warm the duck fat in a saucepan until liquid, and pour it over the legs until they’re fully submerged. Cover with a lid and bake for 6 to 7 hours, until the meat pulls cleanly from the bone. Lift the legs out and place them in a sealable container. Strain the fat through a sieve to remove solids, discard them, and pour the clarified fat back over the duck to cover. Let everything cool to room temperature, then seal and refrigerate. I find that curing the duck in its fat for at least two months deepens the flavor remarkably. To serve, warm the leg gently in the fat and crisp the skin in a hot skillet.

Chef's Tip

I always reserve the strained fat for roasting vegetables or frying eggs—it adds a luxurious depth that you just can’t get from butter. Don’t rush the curing time; patience rewards you with the most tender confit.

Storage Tips

Once cured, store the duck confit submerged in its fat in the refrigerator for up to 3 months. To reheat, gently warm the leg in the fat, then crisp the skin in a hot pan.

Variation Tips

Serve over a bed of wilted spinach with a drizzle of the fat for a simple meal. For a heartier keto plate, pair with creamy cauliflower purée or a crisp arugula salad with lemon vinaigrette. If you can’t find Peking duck legs, Muscovy or standard legs work well.
