This elegant pan-roasted duck breast with mustard greens is a sophisticated yet simple dish that celebrates fresh, peppery flavours. By slowly rendering the fat, the duck achieves a perfectly crisp skin that contrasts beautifully with the tender, succulent meat. The addition of sliced turnips and radishes provides a refreshing crunch, while the mustard-based dressing adds a sharp, savoury depth that cuts through the richness of the poultry.
As a diabetes-friendly main course, this recipe prioritises high-quality protein and nutrient-dense root vegetables over refined carbohydrates. It is a wonderful choice for a low-carb dinner party or a healthy weekend treat. For the best results, use seasonal mustard greens or kale and allow the duck plenty of time to rest before slicing to ensure the juices remain perfectly locked inside.

How to make Duck Breast With Mustard Greens, Turnips, and Radishes
Preheat oven to 400°. Score fat side of duck breasts 1/8" deep in a crosshatch pattern; season both sides with kosher salt and pepper. Heat 1 tablespoon vegetable oil in a large ovenproof skillet, preferably cast iron, over medium. Cook 2 duck breasts, skin side down, until fat is rendered and surface is deeply browned and crisp, 10-15 minutes; transfer to a plate. Wipe out skillet and repeat with remaining duck and 1 tablespoon vegetable oil.
Arrange all duck breasts in skillet, fat side up, and roast in oven until an instantread thermometer inserted into the centre of breasts registers 135°, 5-8 minutes. Transfer to a cutting board and let rest at least 5 minutes and up to 2 hours.
Whisk Dijon mustard, mustard powder, lemon juice, and 45ml olive oil in a small bowl; season mustard sauce with kosher salt and pepper.
Toss radishes, turnips, greens, vinegar, and remaining 2 tablespoons olive oil in a large bowl; season with kosher salt and pepper.
Thinly slice duck. Scatter greens over a platter (or two) and top with duck. Sprinkle with sea salt and serve with mustard sauce alongside.
