Warm Oniion Potato Gratin Recipes

SWEET ONION POTATOES AU GRATIN

Steps:

• Heat a small skillet with the butter over medium heat. Add the onions, season with salt ground thyme, bay leaf and cook until very soft and sweet and lightly caramelized, 20 minutes. Season with salt and pepper, to taste, and discard the bay leaf.
• While the onions cook, put the potatoes in a medium pot and cover with water. Bring to a boil, then salt the water and cook to tender, 12 to 15 minutes. Drain and return the potatoes to the hot pot. Mash the potatoes with the cream and Parmesan and season with salt and pepper, to taste.
• Preheat the broiler.
• Arrange the mashed potatoes in individual gratin dishes or 1 shallow casserole. Top the potatoes with the onions and Gruyere cheese. Put them on a sheet pan and brown under a hot broiler until bubbly, about 2 minutes. Remove from the oven and serve hot.

CREAMY POTATO GRATIN WITH CARAMELISED ONIONS

Steps:

• Up to 2 days before serving, heat oven to 200C/180C fan/gas 6. Heat the oil in a large frying pan. Add the onions and thyme, cover, and cook over a gentle heat for 10-15 mins until softened and caramelised. Pour the cream and milk into a large bowl and season well. Add the potatoes and mix to combine.
• Butter a 23 x 28cm ovenproof dish, then layer in half the potatoes. Spread the onion mixture on top, then layer on the remaining potatoes. Press down with your hands. Pour over the milk mixture, which should come just level with the potatoes. If not, add a little more milk until it does. Cover with foil, then bake for 11⁄2 hrs until tender. Remove from the oven and leave to cool. Cover and store in the fridge.
• On the day, heat the oven to 220C/200C fan/gas 7. Uncover the gratin, spread the crème fraîche on top, then sprinkle over the Parmesan. Put in the oven and cook for 30 mins until the cheese is melted, the top crisp and golden brown, and the gratin piping hot. Serve garnished with extra thyme.

Steps:

• Position a rack in the middle of the oven and crank the heat to 375°F (190°C). Generously butter a 2-quart (1.9 L) casserole dish.
• In a large skillet over medium-high heat, melt the butter.

• Using a mandoline or sharp knife, carefully cut the potatoes into 1/8-inch (3 mm) thick slices.

• Sprinkle 1/3 of the cheese over the top.
• Repeat layering the potatoes, salt and pepper, mushroom-onion mixture, and cheese, two more times.
• Slowly pour the cream into a crevice along the side, being mindful not to wash away the cheese on top.
