Lamb Shoulder with Citrus-Fennel Salad

This slow-roasted lamb shoulder with citrus-fennel salad is a sophisticated yet simple dish that reimagines the traditional Sunday roast. The lamb is gently cooked for several hours in white wine, garlic and rosemary until perfectly tender, allowing the natural flavours to develop without the need for heavy sauces. Scoring the fat allows the aromatic herb rub to penetrate deep into the meat, ensuring every bite is seasoned with zest and spice.

As a diabetes-friendly main course, this recipe balances the rich, savoury notes of the lamb with a bright, crisp salad of seasonal oranges and shaved fennel. The acidity of the citrus and the slight aniseed crunch of the fennel provide a refreshing contrast to the succulent meat. This heart-healthy approach swaps traditional gravy for nutrient-dense pan juices, making it a wholesome choice for a family gathering.

Ingredients for Lamb Shoulder with Citrus-Fennel Salad

  • 1 (5 1/2–6-lb.) lamb shoulder (not tied)

  • Kosher salt, freshly ground black pepper

  • 6 garlic cloves, finely grated, plus 2 heads, halved crosswise

  • 2 tablespoons extra-virgin olive oil

  • 1 teaspoon crushed red pepper flakes

  • 1 teaspoon finely grated orange zest, plus one (3x1") strip zest

  • 2 tablespoons finely chopped rosemary, plus more for serving

  • 240ml dry white wine

  • 6–8 mixed small oranges (such as blood, mandarin, and navel), peeled, halved, sliced or torn into small sections

  • 1 large fennel bulb with fronds, thinly sliced

  • 2 tablespoons fresh lemon juice

Preheat oven to 149°C. Using a sharp knife, score fat across the top of lamb shoulder to create a crosshatch pattern, cutting about 1/4" deep and spacing cuts about 3/4" apart. Season generously all over with salt and pepper.

Combine grated garlic, oil, red pepper flakes, grated zest, and 2 tablespoons rosemary in a small bowl. Rub all over lamb, working into score marks and anywhere there is an opening. Place lamb in a large cast-iron skillet or baking dish. (At this point the lamb can be covered and chilled up to 1 day if you want to break up the prep.)

Arrange garlic heads, cut side down, around lamb and add strip of zest. Pour in wine and cover tightly with foil. Roast until meat is falling off the bone and fork-tender, 5–5 1/2 hours. Keep covered and let rest 30 minutes.

Gently toss orange pieces and fennel with lemon juice in a medium bowl; season lightly with salt.

Tear the meat off the bones in large pieces and mound on a platter. Arrange citrus and fennel salad next to meat. Top meat with more rosemary and drizzle pan juices over.

Lamb can be roasted 1 day ahead. Let cool; cover and chill. Gently reheat, covered, in a 149°C oven until warmed all the way through, at least 1 hour, before serving.
