How to Cook the Perfect Lamb Rack: A Step-by-Step Guide

A quality lamb rack is one of the most impressive cuts you can serve. When buying, look for a rack with even-sized ribs, a good layer of fat on the outside (this bastes the meat during cooking), and pink, firm flesh. The rack should be "frenched" — meaning the rib bones have been cleaned and exposed for an elegant presentation.

Our Gippsland lamb rack from Glen Eyrie Farm features 8 ribs, expertly frenched, from lambs that graze on the lush pastures of Victoria's Gippsland region. The result is meat with a distinctive sweet, delicate flavour and exceptional tenderness.

A full 8-rib rack serves 2-3 people generously, or 4 as part of a multi-course meal. For a dinner party of 6-8, you'll want two racks.

Remove the lamb rack from the refrigerator 30-45 minutes before cooking to bring it to room temperature. This is crucial for even cooking — a cold rack will be overcooked on the outside before the centre reaches temperature.

For a classic herb crust: 2 tablespoons Dijon mustard, 3 tablespoons fresh breadcrumbs, 2 tablespoons fresh rosemary (finely chopped), 2 tablespoons fresh parsley (finely chopped), 2 cloves garlic (minced), 2 tablespoons olive oil, salt and freshly ground black pepper.

First, season the rack generously with salt and pepper. Sear in a hot pan with oil for 2 minutes on the fat side until golden. Brush the fat side with Dijon mustard, then press the herb breadcrumb mixture firmly onto the mustard. The mustard acts as glue and adds a subtle tang.

Preheat your oven to 200°C (fan-forced) or 220°C (conventional).

Place the herb-crusted rack on a wire rack set over a roasting tray, bones pointing up. Roast for:

Rare: 15-18 minutes (internal temp 50°C) Medium-rare: 20-22 minutes (internal temp 55°C) — our recommendation Medium: 24-26 minutes (internal temp 60°C) Well done: 28-30+ minutes (internal temp 70°C) — not recommended

Use a meat thermometer inserted into the thickest part of the meat, not touching bone. The temperature will rise 3-5°C during resting, so pull the rack out 3°C before your target.

For medium-rare (the ideal doneness for lamb rack), the meat should be rosy pink throughout with a thin seared crust on the outside.

This is the step most home cooks skip — and it makes the biggest difference. Rest the lamb rack loosely tented with foil for 8-10 minutes after removing from the oven. During resting, the muscle fibres relax and reabsorb the juices that were pushed to the surface during cooking. Cutting too early means those juices end up on your cutting board instead of in the meat.

To carve, use a sharp knife and cut between each rib bone to create individual cutlets. For a more dramatic presentation, cut between every second bone to create double cutlets.

Serve on warmed plates with your choice of sides. Classic accompaniments include roasted root vegetables, creamy mashed potato, a red wine jus, or a simple green salad with a mustard vinaigrette.
