A Lamb Roast with garlic and rosemary is an elegant main dish that is easier to cook than you think. Doesn’t this look scrumptious?

Sliced leg of lamb roast is good with a little mint jelly.
Lamb Roast, a tasty delight
This year Don and I will be eating Lamb Roast for Easter. What will you serve? We like ours baked in the oven with rosemary and garlic. And we usually buy it with the bone removed, which makes carving it easier. Leave it rolled while cooking, and remove the netting to carve and serve. Sprinkle with rosemary, cut a few slits and insert sliced garlic, and bake. Simple.

A boneless leg of lamb comes wrapped in a net.
Use a meat thermometer and you’ll know when the meat is cooked to your liking. The temperature should be 140°F for rare and 175°F for well done. Don and I like it medium, so about 160°F is perfect.
What You Need
You will need a small knife, a shallow pan with a rack, and a meat thermometer (affiliate link; I like the kind that can be left in the oven the whole time).
