Best 12 Four Onion Gratin Recipes

ONION GRATIN

Steps:

• Spread the onion slices out in a baking dish and drizzle them with olive oil.
• Season with salt and pepper and sprinkle with the thyme.
• Bake in a preheated 375F/190C oven for 15 minutes.
• Meanwhile heat the heavy cream and wine in a sauce pan until it starts to bubble on the edges.
• Spoon the cream over the onions.
• Cover in foil and bake for another 25 minutes.
• Remove the foil and sprinkle the cheese on top.
• Increase the temperature to 450F/230C and bake until golden brown, about 5 minutes.

PEAR AND RED ONION GRATIN

Steps:

• Bosc pears are strong-flavored and hold their shape when cooked, making them well suited for this savory side dish. It's a terrific accompaniment for a glazed ham or grilled sausage or most any roasted meat or poultry.;
• Fill a large bowl three-quarters full with water; add a handful of ice cubes. Cut onion into 16 wedges, place in a strainer and lower into the water. Let stand for 20 minutes.
• Preheat oven to 400degreesF.
• Halve and core each pear; cut each half into 6 slices. Drain the onion wedges well and place them in a 9-by-13-inch glass baking dish along with the pear slices, 1 tablespoon oil, thyme, salt and a grinding of pepper; toss to combine. Cover with foil.
• Roast for 30 minutes, stirring twice.
• Meanwhile, combine breadcrumbs and cheese in a small bowl. Drizzle with the remaining 2 tablespoons oil; stir to combine. Remove the pan from the oven, sprinkle the crumb mixture evenly over the gratin, return to the oven and roast until the breadcrumbs are well browned, 20 to 30 minutes more. Let cool for 10 minutes before serving.
• Recipe Tips & Notes:
• 1. Note: We like to use the Ian's brand of coarse dry breadcrumbs, labeled "Panko breadcrumbs." Find them in the natural-foods section of large supermarkets.
• 2. To make your own breadcrumbs: Trim crusts from firm sandwich bread. Tear the bread into pieces and process in a food processor until coarse crumbs form. One slice makes about 1/3 cup. Spread the breadcrumbs onto a baking sheet and bake in a 250degreesF oven until dry and crispy, about 15 minutes.

FOUR-ONION GRATIN

Steps:

• Melt butter in heavy large skillet over medium heat. Add leeks, large onions, shallots and garlic and sauté until all are tender, about 20 minutes. Add baby onions and cook 10 minutes longer, stirring occasionally. Mix in 2 cups whipping cream. Boil until cream is thickened to sauce consistency, about 10 minutes. Transfer vegetable-cream mixture to 6-cup shallow baking dish. (Can be prepared 1 day ahead. Cover and refrigerate. Return mixture to room temperature before continuing.)
• Preheat oven to 425°F Sprinkle breadcrumbs over onion mixture. Bake until breadcrumbs are golden brown and onion mixture bubbles, about 20 minutes. Sprinkle with parsley.

CREAMED ONION GRATIN

Steps:

• Preheat the oven to 375 degrees. Lightly grease a gratin dish or medium casserole.
• Cut off the root and tip of the onions. Slice in half length-wise and peel. Lay the cut-side of the onion down and slice length-wise into thick wedges.
• In a Dutch oven or heavy pot, melt two tablespoons of butter over medium heat. Add the onions and cook, stirring occasionally, until soft and caramelized, about 40 minutes. Add the sherry and simmer until it evaporates. Remove the onions from the pan and pour through a fine mesh sieve. Let them drain while making the bechamel sauce. (Draining the onions prevents a runny gratin because the onions will continue to release more liquid in the oven.)
• In the same Dutch oven, melt 3 tablespoons of butter over medium heat. Stir in the flour and cook for one minute. Add the scalded milk and cook, whisking constantly, until the sauce is very thick. Remove from the heat. Fold in the Gruyere and stir until completely melted. Season with salt and pepper, to taste. Add the onions to the cheese sauce and toss to thoroughly coat. Pour the onion mixture into the gratin dish.
• Melt the remaining tablespoon of butter and toss with the panko crumbs. Sprinkle over the top of the onions and bake until bubbly and golden brown, about 30 minutes. Serve warm.
