Herb-Crusted Roast Rack of Lamb with Citrus Glaze

Why This Herb-Crusted Roast Rack of Lamb with Citrus Glaze Works

In the hot oven, the outside of the lamb browns first while the inside slowly warms up. As the meat heats, the fat in the rack starts to melt and run through the meat, so it stays moist instead of drying out. During this time, the breadcrumb, herb, and garlic coating firms up into a crust. The mustard under the crumbs acts like glue, so the crumbs stick to the lamb instead of falling off when it cooks.

While the lamb roasts, the orange juice, lemon juice, and honey simmer and lose water, so the glaze becomes thicker and a bit sticky. By the time it is brushed on the lamb and goes back in the oven, the glaze clings to the crust instead of sliding off. In those last minutes, the glaze tightens and the crust stays crisp, while the meat finishes cooking inside. Resting at the end lets the hot juices settle back into the lamb, so the slices stay juicy when cut.

Mistakes To Avoid

Letting the lamb roast the full time without checking doneness can leave it overcooked and dry, especially if the racks are smaller or the oven runs hot. The outside will look great and browned, but the meat inside turns gray and firm instead of pink and juicy.

Putting the lamb straight into the oven straight from the fridge often leads to uneven cooking. The outside crust browns fast while the cold center lags behind, so by the time the middle is done, the outer layer has tightened up and lost moisture.

Pressing on a very thick layer of breadcrumbs makes the crust heavy and slow to crisp. The top can stay soft and pasty while the lamb underneath steams, so the coating slides off in chunks when sliced instead of clinging in a thin, crunchy layer.

Rushing the citrus glaze and not reducing it enough leaves it watery. When it is brushed on, it runs off the lamb and onto the tray, so the meat ends up sticky in spots instead of getting a shiny, lightly tacky coating.
