Baked Tomato Gruyère Potato Gratin Recipes

BAKED TOMATO, GRUYèRE & POTATO GRATIN

Steps:

• Heat oven to 180C/160C fan/gas 4. Generously grease a large, deep, ovenproof dish. Strip the leaves from 3 of the thyme sprigs. Mix the gruyère with all but 2 tbsp of the grated parmesan, then mix the double cream with the stock.
• Start layering up the sliced potatoes with sprinklings of the shallots, garlic, thyme leaves, cheese and most of the walnuts, plus plenty of seasoning. Drizzle a little of the cream mixture over each layer too. When you've layered in half of those ingredients, top with half of the tomatoes. Continue layering the rest of the ingredients, finishing with the last of the cream. Top with the remaining tomatoes, then sprinkle over the breadcrumbs, the remaining parmesan and walnuts, and enough thyme to look pretty. Add a few more knobs of butter, then cover with foil.
• Bake the gratin for 1 hr 15 mins, then remove the foil and bake for a further 40 mins until golden and crispy on top, and a knife poked into the centre of the potatoes slides in easily. Leave to rest for 10-15 mins, then serve.

POTATO, ZUCCHINI, AND TOMATO GRATIN

Steps:

• Preheat oven to 375 degrees with rack in upper third. Coat a 9-by-13-inch gratin dish with 1 teaspoon oil, and sprinkle with garlic. Using a mandoline or a very sharp knife, slice potatoes and zucchini as thinly as possible into rounds. Arrange potatoes, zucchini, and tomatoes in overlapping layers around prepared dish, and sprinkle with the salt and pepper. Drizzle with remaining 4 teaspoons oil, and sprinkle with thyme and cheese.
• Cover with foil; bake until potatoes are tender, 35 to 45 minutes. Remove foil; continue baking until top is golden brown, about 25 minutes more. Remove from oven; and serve immediately.

GRUYERE POTATO GRATIN

Steps:

• Preheat oven to 350 degrees F (175 degrees C). Butter a 9x13 inch baking dish with the softened butter.
• Toss the potato slices and chopped onions with salt and pepper, and spread 1/3 of the mixture into the prepared baking dish. Sprinkle half of the Gruyere cheese over the potatoes, then add another layer of potatoes. Sprinkle on the remaining cheese followed by the remaining potatoes. Mix together the water and wine, and pour into dish. Cover the baking dish with aluminum foil.
• Bake in preheated oven until the potatoes are tender, about 1 hour 15 minutes. Once tender, remove the foil, and pour the cream evenly over the potatoes. Bake uncovered for an additional 15 minutes to brown the top and thicken the cream.

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.

POTATO GRATIN WITH THYME

Steps:

• Preheat oven to 400 degrees F. Butter a 1 1/2-quart shallow baking dish.
• Bring a large saucepan of salted water to a boil. Peel potatoes and cut into 1/8-inch slices - a food processor is good for this. Add potatoes to boiling water and cook 4 minutes. Drain potatoes thoroughly in a colander.
• Arrange 1/3 of the potatoes in baking dish, top with 1/3 of the cheese, 1/3 of the thyme leaves, and sprinkle with salt and freshly ground pepper. Repeat twice more, ending with a layer of cheese and thyme.
• Heat milk just to boiling. In a small bowl whisk egg and add hot milk, stirring. Pour evenly over potatoes. Bake 30 minutes, or until top is golden and potatoes are tender.
