Ingredients for Rosemary Rack of Lamb with Roasted Potatoes and Carrots for Two

  • 1 (1–675g) rack of lamb, fat cap scored

  • 1 garlic clove, finely chopped

  • 2 teaspoons chopped rosemary

  • 1/8 teaspoons freshly ground black pepper

  • 1 1/4 teaspoons kosher salt, divided

  • 1 tablespoon white miso paste

  • 1/4 teaspoons smoked paprika

  • 5 tablespoons unsalted butter, softened, divided

  • 2 medium yukon gold potatoes (about 450g )

  • 1 teaspoon honey

  • 1/4 teaspoons ground coriander

  • 230g medium carrots, peeled

  • 1 tablespoon finely chopped parsley

Preheat oven to 218°C. Rub lamb with garlic, rosemary, pepper, and 1/2 teaspoons salt.

Combine miso, paprika, 4 tablespoons butter, and 1/2 teaspoons salt in a small bowl; set aside.

Peel potatoes. Working with one potato at a time, slice a thin sliver off one long side to make a flat bottom. Trim ends off, then slice vertically every 1/16", cutting down to 1/4" from the bottom. (To make sure you do not cut all the way through the potato, line it with chopsticks on each side to stop your knife.) Brush potatoes with miso butter, fanning slices open to get butter between each slice. Transfer to a rimmed baking sheet and roast 15 minutes.

Remove baking sheet from oven and brush potatoes with more miso butter. Arrange lamb on baking sheet alongside potatoes and roast, brushing potatoes with miso butter halfway through, until an instant-read thermometer inserted into the thickest part of the lamb registers 52°C for medium-rare, and the potatoes are fork-tender, 20–25 minutes. Transfer lamb to a cutting board and let rest 10 minutes, and continue roasting the potatoes if needed until fork-tender.

Meanwhile, mix honey, coriander, and remaining 1 tablespoon butter and 1/4 teaspoons salt in a small bowl, then brush over carrots. Arrange carrots on a baking sheet and roast until lightly browned and fork-tender, 15–20 minutes.

Slice lamb between each rib. Brush potatoes with remaining miso butter, top carrots with parsley, and serve alongside lamb.
