Making the Dauphinoise Potatoes

While the lamb is resting, prepare the Dauphinoise Potatoes. Preheat your oven to 325°F (160°C). In a large bowl, combine the thinly sliced potatoes, heavy cream, milk, minced garlic, nutmeg, salt, and pepper. Toss everything together to ensure the potatoes are evenly coated. Layer the potato mixture into a greased baking dish. If using, sprinkle the grated Gruyère cheese over the top. This lamb dauphinoise pairing is a match made in heaven!

Slow Roasting the Lamb and Potatoes

Pour the red wine (if using) and lamb or chicken broth into the bottom of the roasting pan around the lamb. Cover the lamb with aluminum foil and roast for 3-4 hours, depending on the size. In the last hour of cooking, add the Dauphinoise Potatoes to the oven alongside the lamb. Ensure both the lamb and the potatoes are cooking evenly. The slow roasting process ensures the oven roasted lamb is tender and flavorful. Remove the foil during the last 30 minutes to allow the lamb to develop a beautiful, golden-brown crust.

Resting and Serving

Once the lamb is cooked to your desired doneness (use a meat thermometer for accuracy), remove it from the oven and let it rest for at least 15-20 minutes before carving. This allows the juices to redistribute, resulting in a more tender and flavorful roast. While the lamb is resting, check the Dauphinoise Potatoes to ensure they are golden brown and tender. Baste the slow roast lamb with the pan juices before carving. Slice the lamb and serve it hot with a generous helping of Dauphinoise Potatoes. Don’t be afraid to serve it family style! Consider sides such as our family favorite garlic roasted potatoes.
