Step 1

Preheat your oven to 400 degrees.

Step 2

Place the garlic on the bottom of the roasting pan. Place the leg of lamb on top of the garlic. Arrange the onions around the lamb.

Step 3

Whisk the marinade and pour over the lamb. Rub it all over so that everything is marinated. Sprinkle the salt and black pepper over everything. Make sure that you season all sides of the lamb.

Step 4

Cover with aluminum foil and bake at 400 degrees for 30 minutes.

Step 5

In the meantime, peel and quarter the potatoes and place them in a large bowl covered with cold water.

Step 6

Reduce the temperature to 350 degrees and cook for 1 and 1/2 hour more covered with foil.

Step 7

Drain the water out of potatoes and drizzle about 1/4 cup or less olive oil over them. Lightly season them with salt, pepper, and some dried oregano. Add the potatoes to the roasting pan with the lamb and bake covered for an hour.

Step 8

Remove the foil and bake for about 30 minutes more or until the meat is falling off the bone. Remember to baste the lamb with the sauce in the pan each time you handle the pan.

Step 9

Remove from the oven and let it rest for 25 minutes in the roasting pan. Transfer it onto a nice platter with the potatoes and serve it with a delicious salad and crusty bread! You can also prepare some more ladolemono sauce to serve with the lamb. Enjoy!!

Step 10

OPTIONAL: The potatoes can be peeled and left whole so that you may cook them together with the lamb from the start. They will be very flavorful but will become a bit dark. It's up to you! Let me know which way you like it better in the comments section below.
