Best The Best Onion Gratin Recipes

ONION GRATIN RECIPE

Steps:

• Melt the butter in a cast iron skillet over a medium flame until it begins to foam, toss the sliced onions into the hot fat and fry them, stirring frequently, until they release their fragrance and become tender and translucent.
• Preheat the oven to 425 degrees Fahrenheit.
• While the oven preheats, reduce the heat to medium-low, pour two cups cream into the skillet over the onions and simmer them together until cream thickens and is reduced by half, about fifteen minutes.
• In a separate bowl, stir two cups whole grain sourdough bread crumbs with two tablespoons minced fresh thyme and one-quarter cup minced Italian flat-leaf parsley. Season the mixture of breadcrumbs and herbs with unrefined sea salt as it suits you.
• Remove the onions and cream from the heat. Top them with seasoned breadcrumbs and one-half cup grated pecorino romano cheese.
• Place the onion gratin in an oven preheated to 425 degrees Fahrenheit and bake for twenty to twenty-five minutes or until the season breadcrumbs and cheese form a nice golden crust and the cream begins to bubble.
• All the onion gratin to rest for about five minutes before serving.

ONION GRATIN

Steps:

• In a large size heavy skillet melt the butter and cook the onions over medium heat until soft, between 15 and 20 minutes, stirring frequently with a wooden spoon. You do NOT want the onions to be crunchy later.
• Add flour, stirring, and cook about 1 minute.
• Gradually stir in milk and cook 4 minutes; add cream, salt, and pepper.
• Remove skillet from stove top and set aside to cool slightly.
• Preheat oven to 400*F.
• When oven is pre-heated, taste sauce and adjust with more salt and pepper to suit your taste preferences (I like to add quite a bit more pepper).
• After taste adjustment, add 1 beaten egg to the cooled onion mixture and whisk thoroughly to combine.
• Pour the onion sauce into a lightly sprayed pie dish.
• Cover with layer of egg slices and sprinkle with cheese.
• Bake until lightly browned, about 15 minutes-depends upon your oven.
• Top with bacon crumbles.
• Allow to set for 5 minutes so that it will set up and be easier to plate.

ONION GRATIN

Steps:

• Bring a pot of water to a boil and add salt. Preheat the oven to 400°F.
• Drop the onions into the water and leave them there for a minute. Peel them, then put them in a buttered ovenproof dish large enough to hold them in one layer. Sprinkle them with salt, pepper, and a little nutmeg, then pour the cream over all. Bake until the top is brown and the onions are soft, about 30 minutes.

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.
