French Onion Strata Recipes

FRENCH ONION STRATA

Steps:

• For the Caramelized Onions: In a large skillet, melt butter over medium heat, then add onions, sugar, and 1 teaspoon salt. Cover and cook, stirring every few minutes, until onions have softened, about 10 minutes. Remove lid and cook, stirring frequently and keeping skillet uncovered, until onions are deep golden brown, 20 to 25 minutes; if onions threaten to burn at any point, stir in a tablespoon or two of water as needed, and/or lower heat. Add garlic and thyme and cook 1 minute longer. Add sherry and wine and cook until liquid has almost completely evaporated, about 3 minutes. Remove from heat and set aside.
• Meanwhile, for the Strata: Preheat oven to 350°F (177°C). Spread bread in a single layer on a baking sheet. Bake until bread is dry but not browned, about 8 minutes.
• In a large bowl, whisk together eggs, half and half or milk, mustard, Worcestershire sauce, fish sauce (if using), 1/2 teaspoon salt, and pepper. Add dried bread and let soak in custard for at least 15 minutes and up to 30 minutes.
• Butter a 12-inch cast iron skillet or a 9- by 13-inch baking dish and add half of bread. Scatter half of caramelized onions and half of cheese all over. Layer remaining bread on top and scatter remaining onions and cheese over. Drizzle any remaining custard all over, then bake until bread is crisp and custard is just set, about 35 minutes. Serve hot or at room temperature.

FRENCH ONION BREAKFAST STRATA

Steps:

• Rub a small splash of olive oil across an 8-inch baking dish, or equivalent.
• In a medium bowl, whisk together the oil, onion dip mix, and milk. Add the eggs and whisk well again. Arrange the bread cubes in the prepared baking dish in an even layer. Very slowly, drizzle the liquid mixture over the bread and sprinkle with the cheese. Cover the dish and refrigerate overnight.
• When you are ready to bake, preheat the oven to 350°F and place a rack in the center. Bake the strata, uncovered, for 45 to 55 minutes, until the egg is set and puffy and the edges are golden brown. (Cut into it to be sure it is well cooked.)
• Serve the strata warm, drizzled with a bit of olive oil and sprinkled with chives.

CARAMELIZED ONION, SPINACH AND GRUYERE STRATA WITH SAUTEED CHERRY TOMATOES

Steps:

• Preheat the oven to 325 degrees F. Put the bread on a baking sheet and toast until lightly golden brown on both sides, about 10 minutes. Remove and let cool.
• Meanwhile, heat the butter and canola oil in a large saute pan over medium heat until shimmering. Add the onions and toss to coat, then add the sugar and season with salt and pepper. Cook, stirring occasionally, until the onions are golden brown and caramelized, about 20 minutes. Remove from the heat and let cool slightly.
• In a large bowl, combine the toasted bread, caramelized onions and spinach. In another large bowl, whisk the eggs, milk, heavy cream, 1 1/2 cups cheese, the mustard, 1 teaspoon salt, 1/2 teaspoon pepper, the thyme and nutmeg. Butter a 9-by-13-inch baking dish. Add the bread mixture to the baking dish, then pour the egg mixture over the bread and press down to make sure it is totally submerged.
• Increase the oven temperature to 350 degrees F. Bake the strata, uncovered, until it is golden brown on top, puffed slightly and doesn't shimmy with uncooked custard when you shake the pan, 50 minutes to 1 hour; sprinkle with the remaining 1/2 cup cheese during the last 10 minutes of baking. Let cool 5 minutes before serving.
• Meanwhile, prepare the tomatoes: Heat the canola oil in a large saute pan over high heat until it begins to shimmer. Add the cherry tomatoes, season with salt and pepper and cook until softened, 4 to 5 minutes. Add the chives and remove from the heat. Serve the strata with the sauteed tomatoes.
