Duck Confit with Lentils

Duck confit with lentils is a classic French-leaning dinner built on the natural partnership between rich, tender duck and earthy pulses. Fully cooked confit-style legs are reheated until the skin turns crisp, then served over green lentils simmered with shallot, carrot, garlic, bay and thyme. The lentils stay distinct rather than mushy, giving the dish a satisfying, rustic base that catches the savoury duck juices. A final spoonful of mustard sharpens the stocky, herbal flavours without overwhelming them, making this a practical but elegant main course for a relaxed dinner.

Why this recipe works

  • Crisp skin, tender base: Roasting the confit duck separately keeps the skin crisp while the lentils stay soft and spoonable underneath.
  • Built-in savoury depth: Duck fat, aromatics, herbs and stock give the lentils a rounded flavour without needing a long braise.
  • Mustard cuts the richness: Stirring mustard through at the end adds brightness and stops the duck and lentils from feeling too heavy.

Texture tips

  • For crisper duck skin: Pat the duck legs very dry before roasting and keep them skin-side up so the fat can render and the surface can brown evenly.
  • Keep the lentils intact: Simmer gently rather than boiling hard; green lentils should be tender but still hold their shape.

Timing notes

  • Cook both elements together: Start the duck first, then prepare and simmer the lentils while it roasts so both components finish at roughly the same time.
  • Serve as soon as assembled: Plate the lentils first and set the duck on top just before serving to preserve the crisp skin.

Make-ahead tips

  • Store separately: Refrigerate the duck and lentils in separate containers where possible, which helps the duck skin re-crisp more successfully.
  • Reheat without softening the skin: Warm the lentils gently with a splash of stock, then re-crisp the duck in a 200°C (390°F) oven until piping hot.

Authenticity notes

  • A classic French pairing: Duck confit and lentils are a natural match in French cooking: rich, salty duck is balanced by earthy legumes and sharp mustard.
  • Home-style shortcut: Using fully cooked confit-style duck legs keeps the character of the dish while making it practical for a weeknight dinner.

  1. Heat the oven to 220°C (430°F). Pat the duck legs dry and set them skin-side up on a baking tray or in a roasting pan.
  2. Put the duck in the oven and roast for 20 to 25 minutes until the skin is deeply golden and crisp and the meat is piping hot. If the skin is colouring too quickly, turn the oven down to 200°C (390°F).
  3. Meanwhile, finely chop the shallots, cut the carrots into small dice, and crush the garlic. Rinse the lentils under cold water in a sieve until the water runs mostly clear.
  4. Melt the duck fat in a saucepan over medium heat. Add the shallots and carrots and cook for 6 to 8 minutes until softened, then stir in the garlic for 30 seconds until fragrant.
  5. Add the lentils, bay leaves and thyme, then pour in the hot chicken stock. Bring to a gentle simmer, then cook for 22 to 28 minutes, stirring occasionally, until the lentils are tender but still holding their shape and the liquid is lightly reduced.
  6. Fish out the bay leaves and thyme sprigs, then stir the mustard through the lentils. Spoon the lentils onto plates and set a crisp duck leg on top of each portion.

Recipe notes

Tips

  • Keep the lentils at a gentle simmer rather than a rapid boil so they cook evenly and stay intact.
  • If the pan looks dry before the lentils are tender, add a splash more chicken stock and continue cooking until they are just soft.
  • This method assumes the duck legs are confit and fully cooked; if serving vulnerable groups, ensure the duck is reheated until piping hot throughout.

Substitutions

  • Replace chicken stock with vegetable broth for a lighter, less meaty lentil base.
  • Replace mustard with dijon-mustard for a smoother, sharper finish.

Storage

  • Refrigerate up to 3 days
  • Cool the duck and lentils quickly, then refrigerate separately if possible. Reheat the lentils gently in a saucepan with a splash of chicken stock, and re-crisp the duck in a 200°C (390°F) oven for 12 to 15 minutes until piping hot.
