Best 6 Roasted Lamb With Potato Onion And Tomato Gratin Recipes

LEG OF LAMB ROASTED OVER POTATO-ONION GRATIN RECIPE - (4.2/5)

Steps:

• Prepare Lamb: Rub garlic paste all over lamb. Rub olive oil all over the leg, then generously season with salt and pepper. Set lamb aside at room temperature for 2 hours. Prepare Gratin: Preheat oven to 400 degrees. Choose a baking dish large enough to hold lamb comfortably. Rub interior of dish with the cut side of a halved garlic clove. In the dish, place potatoes, 1 teaspoon thyme, 1 teaspoon salt, 1 teaspoon pepper, garlic, and 2 teaspoons olive oil. Toss everything together and spread potatoes out in an even layer across dish. In a medium bowl, toss 2 yellow onions together with 1 teaspoon thyme , 1 teaspoon salt, 1 teaspoon pepper and 2 teaspoons olive oil. Evenly scatter onions over top of potatoes. Pour wine over vegetables. Place baking dish with gratin on lowest oven rack. If dish is not large enough to hold lamb and catch all drippings, place a baking sheet or piece of aluminum foil under dish. Place leg of lamb directly on rack above gratin and make sure baking dish is positioned so it catches all drippings. Roast 15 minutes, then lower oven temperature to 350 degrees. Continue roasting lamb until meat thermometer inserted into thickest part registers 125 degrees for medium-rare, about 1¼ hours. (For medium doneness, cook until temperature reads 135 degrees; for medium-well, 145 degrees.) Check gratin after 1 hour of cooking. If potatoes are fork-tender, remove gratin from oven. If the roast needs more cooking time, place (or leave) a baking sheet or aluminum foil on rack beneath lamb to catch drippings. Once lamb reaches desired doneness, transfer to a cutting board and let rest at least 10 minutes. While lamb and potatoes roast, make Salsa Verde: In a small bowl, mix parsley, mint, thyme, vinegar, honey, olive oil, salt and pepper. Add more olive oil, vinegar and salt as needed. Serve lamb with gratin and salsa verde alongside.

POTATO-TOMATO GRATIN

Steps:

• Preheat the oven to 350 degrees F.
• Heat a large saute pan or Dutch oven over high heat for 2 minutes. Swirl in 3 tablespoons olive oil, and then add the onions, 1 teaspoon thyme, 1 teaspoon salt and some pepper. Cook 6 minutes, stirring often, and then turn the heat down to medium. Add the butter, and cook 15 minutes, stirring and scraping with a wooden spoon, until the onions start to caramelize. Turn the heat down to low and continue cooking for about 10 minutes, stirring often, until the onions are a deep golden brown. Remove the pan from the heat and set aside.
• Use a mandoline to slice the potatoes into 1/8-inch-thick rounds. Toss them with the cream, 1 teaspoon thyme, 1 teaspoon salt and some pepper.
• Cut the tomatoes into 1/4-inch-thick slices. Arrange them on a plate and season with 1 teaspoon salt and some pepper.
• Place half the caramelized onions in an even layer in a 9-by-9-inch (or equivalent) gratin or baking dish. Arrange one layer of alternating potatoes and tomatoes on top of the onion layer. Layer a couple of slices of cheese and scatter some olives over the cheese. Drizzle with 2 tablespoons of the cream from the potatoes and 1 tablespoon olive oil. Season with 1 teaspoon salt, a healthy pinch of pepper, 1/2 teaspoon thyme and half the basil.
• Scatter the rest of the caramelized onions over the potatoes and tomatoes. Arrange another layer of potatoes, tomatoes and cheese on top; make this layer pretty, because it will be the top of your gratin. Pour the remaining cream from the potatoes and the remaining 1 tablespoon olive oil over the potatoes and tomatoes. Season with 1/4 teaspoon salt, a pinch of pepper, and the remaining 1/2 teaspoon thyme, olives and basil. Press the vegetables down with your fingers. The cream and oil will come up through the layers and coat the vegetables evenly.
• Cover the baking dish tightly with aluminum foil. Bake until the potatoes are tender when pierced, about 2 hours. Remove the gratin from the oven and uncover it, being careful of the steam.
• Turn the oven up to 450 degrees F and return the gratin, uncovered, to the oven. Cook until the juices have thickened and the top is nice and golden brown (as in "gratineed"), another 25 to 30 minutes.
