Seared duck breast is first pan-seared skin-side down and then roasted in the oven after seasoning with salt and black pepper. A cauliflower-parmesan purée is made by puréeing cooked cauliflower with heavy cream and parmesan until smooth. The baby spinach is quickly wilted with garlic, olive oil and a splash of lemon juice to keep it tender and bright. Resting the duck for six to eight minutes after roasting allows the meat to relax so slices remain moist when arranged over the purée.

Method

  1. Preheat oven to 160°C (325°F). Score the skin of the duck breast in a crosshatch pattern without cutting the flesh, then season both sides with salt and black pepper.
  2. Place a cold heavy skillet over medium-high heat. When hot, add the duck breasts skin-side down and sear without moving for 6 to 8 minutes, until the skin is deeply browned and fat has rendered. Flip and sear the flesh side 1 to 2 minutes.
  3. Transfer the skillet to the oven and roast at 160°C (325°F) for 10 minutes for medium doneness. Remove from oven and transfer duck to a cutting board to rest, loosely tented, for 6 to 8 minutes.
  4. While the duck roasts, cut the cauliflower into even florets. Bring the water to a simmer in a saucepan, add a pinch of salt, and simmer the cauliflower until very tender, 10 to 12 minutes. Reserve some of the cooking liquid, then drain the cauliflower.
  5. Return the drained cauliflower to the still-warm saucepan, add the heavy cream, butter, and parmesan cheese. Use an immersion blender or transfer to a high-speed blender and purée until smooth, adding reserved cooking liquid a little at a time to reach a silky consistency. Adjust seasoning with salt, black pepper, and lemon juice.
  6. Thinly slice or finely mince the garlic. In a clean skillet over medium heat, warm the olive oil and add the garlic for 30 seconds until fragrant. Add the baby spinach and toss until just wilted, 1 to 2 minutes, then finish with a small squeeze of lemon juice and a light pinch of salt.
  7. Slice the rested duck breast thinly across the grain. Spoon a portion of cauliflower-parmesan purée onto each plate, arrange wilted baby spinach alongside, and fan sliced duck breast on top.
  8. Finish with a sprinkle of chopped parsley and a few extra shavings of parmesan if desired. Serve immediately.

Tips

Pro tip

  • Allow the duck to rest loosely tented before slicing to keep juices in the meat.
  • Blend the cauliflower while still hot and add reserved cooking water a little at a time for a silkier purée.
  • Use a fine grater for the parmesan to help it melt smoothly into the purée.

Frequently asked questions

Can I use the reserved cauliflower cooking liquid instead of some or all of the heavy cream?
Yes. Replacing part of the heavy cream with the reserved cauliflower cooking liquid will thin the purée and reduce its richness, so add the liquid gradually to reach the desired silky consistency while retaining some cream for body and mouthfeel.
What can I use instead of parmesan in the purée?
Use extra butter and a little more salt if parmesan is not available. Parmesan contributes savory umami and a salty finish; substituting with more butter preserves richness but results in a milder, less savory purée.
Can I omit the lemon juice from the spinach?
Yes, you can omit the lemon juice, but the lemon brightens the spinach and helps cut the richness of the duck and purée. If leaving it out, consider a slightly lighter toss of the garlic and a modest seasoning adjustment with salt to keep the greens lively.
Why didn’t the duck skin get crispy?
Because the fat didn’t render fully or the skin was moved too soon, the skin will stay soft. Start with a cold heavy skillet, score the skin, place skin-side down and leave it undisturbed until the fat has rendered and the skin is deeply browned; pat the skin dry and season before searing to encourage crisping.
Why is the cauliflower purée grainy or not silky?
Typically the cauliflower wasn’t cooked until very tender or it wasn’t puréed long enough. Simmer the florets until very soft, drain well, then blend with heavy cream, butter and parmesan while adding the reserved cooking liquid a little at a time until the texture is smooth and silky.
Why did the spinach release too much liquid or become soggy?
Overcooking or steaming the spinach causes excess liquid and limp leaves. Cook the garlic only briefly in warmed olive oil, add the baby spinach and toss just until it is wilted—one to two minutes—then finish with lemon juice so the greens retain tenderness without turning watery.
How should I store leftovers, and how do I reheat them?
Refrigerate leftovers within 2 hours of cooking — within 1 hour if the room is above 90°F (32°C). USDA general guidance for cooked leftovers is 3 to 4 days in the refrigerator at 40°F (4°C) or below, or the freezer for longer. Reheat until steaming hot throughout, to 165°F (74°C). These are USDA FoodKeeper general guidelines, not a measurement of this specific recipe.
