Spinach Mushroom Brunch Casserole Recipes

Steps:

• Grease a 9-by-13-inch (3-quart) casserole dish with oil.
• Toss the bread cubes with 2 tablespoons of the oil, 1/4 teaspoon salt and a few grinds of pepper in a large bowl. Heat a large skillet over medium heat. Add the bread to the skillet, and cook, tossing occasionally, until toasted and golden brown, about 8 minutes. Return the toasted bread to the bowl to cool.
• Wipe out the skillet. Heat the remaining 2 tablespoons oil over medium-high heat until it starts to shimmer. Add the mushrooms in one layer (resist the urge to stir right away), and cook until they start to brown, about 3 minutes; stir, then continue to brown for 2 minutes more. Add the garlic, thyme, 1/4 teaspoon salt and some pepper, stir continuously for 1 minute, then fold in the spinach and another 1/4 teaspoon salt. Continue to cook, stirring often, until the spinach is wilted, 1 to 2 minutes. Remove from the heat.
• Place half the bread cubes in the prepared casserole dish, and sprinkle them with half each of the Gruyere and Parmesan. Add the mushroom-spinach mixture in an even layer. Top with the remaining bread cubes, Gruyere and Parmesan.
• In a large bowl, whisk together the eggs, half-and-half, 1/2 teaspoon salt and several grinds of pepper. Pour the egg mixture into the casserole dish. Cover with plastic wrap, and refrigerate for at least 6 hours up to overnight. Remove the casserole from the refrigerator 30 minutes before baking.
• Preheat the oven to 350 degrees F. Bake the casserole until the custard is set and the top is golden brown, 50 to 55 minutes. Cool for at least 15 minutes before serving warm or at room temperature.

Steps:

• Place the bun tops, top down, in a buttered, 13- x 9-inch casserole dish. Set aside the bun bottoms.
• In a large skillet, melt butter over medium-high heat, until sizzling.
• Add onion and saute until they're just softening. Add mushroom slices and stir, reducing heat to medium. Cook for about 5 minutes.
• Stir in herbs, garlic, paprika and salt and pepper to taste, then add spinach and cook another 3 minutes, stirring to wilt the spinach. Remove from heat.
• Spoon half the vegetable mixture evenly over the bun tops in the casserole dish. Scatter half the bacon and cheese evenly on top.
• Place the bun bottoms, with cut side up, in the casserole to form the top layer.
• Spoon the rest of the vegetable mixture, bacon and cheese over the top layer of buns.
• In a bowl, stir together eggs and milk until blended.
• Pour the mixture evenly over the casserole. Using a spatula, press down firmly on each of the buns to submerge in the liquid. Cover tightly with plastic wrap and refrigerate 8 hours or overnight.
• In the morning, let casserole sit at room temperature for about 30 minutes.
• Preheat oven to 350 degrees. Bake for 35 to 40 minutes or until firm at the center and a toothpick inserted comes away clean. Serve warm.

Steps:

• Preheat oven to 325 degrees.
• Wash fresh spinach, drain well and chop coarsely, or drain frozen spinach very well after thawing.
• Melt butter in saucepan, saute onion and mushrooms for 5 minutes.
• Blend in flour, salt, pepper and nutmeg.
• Add cream gradually, stirring steadily to boiling point; cook over low heat 5 minutes.
• Arrange successive layers of spinach and sauce in a buttered 1 1/2 qt casserole ending with sauce.
• Sprinkle with cheese.
• Place in a shallow pan of hot water.
• Bake for 45 minutes.

Steps:

• Preheat the oven to 375 degrees. Spray a 9-by-13-inch baking pan with nonstick cooking spray or grease with butter.
• Heat 1 tablespoon of the olive oil over medium-high heat. Add the mushrooms and cook, stirring occasionally, until wilted and beginning to brown; about 5 minutes. Add the spinach, 1 teaspoon salt and a few grinds of pepper. Cook until spinach just begins to wilt, stirring occasionally, about 2 minutes. Remove pan from heat and set aside to cool.
• Whisk the eggs, milk, 1 teaspoon salt and a few grinds of pepper together in a large bowl. Gently whisk in the cooled mushroom mixture, then pour the egg mixture into the prepared pan. Bake until puffed and set, 15 to 20 minutes. Remove from the oven and let cool.
• Place the English muffins cut-side up on a baking sheet and brush with some butter if using. Bake until slightly toasty, 3 to 4 minutes.
• Once the eggs are cool enough to handle, use a large round biscuit cutter (about 3 3/4 inches in diameter) or the rim of a juice glass to cut out 6 rounds of egg. (For ways to use the leftover egg scraps, see Cook's Note.) Using an offset spatula or a butter knife, remove each egg round from the pan and place on bottom half of an English muffin. Top each with a slice of Swiss cheese and the other muffin half. Wrap each sandwich individually with aluminum foil, put in a resealable plastic bag and freeze up to 1 month or refrigerate for up to 1 week.
• To reheat, unwrap a sandwich and place on a paper towel on a microwave-safe dish. Microwave 1 to 1 1/2 minutes, until the cheese is melted and eggs are warmed through. Alternatively, thaw a foil-wrapped frozen sandwich overnight in the refrigerator, then bake in a 425-degree F oven until warmed through and the cheese is melted, about 10 minutes.

Steps:

• Preheat oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking dish with 1 teaspoon butter.
• Whisk eggs in a large bowl. Add cottage cheese, Monterey Jack cheese, 1/2 cup melted butter, flour, spinach, mushrooms, baking powder, and salt; mix. Pour egg mixture into prepared baking dish.
• Bake in the preheated oven until eggs are set and a knife inserted into the center comes out clean, about 35 minutes.

Steps:

• Preheat oven to 350.
• Grease 9" square pan with a bit of butter.
• Add rest of butter to skillet. Saute onion for 2 minute on med heat, then add mushrooms and garlic. Cook and stir for 4 minutes, until mushrooms have begun to soften, and remove to a bowl.
• Add spinach to skillet and saute lightly, just for a minute or two. Drain by pressing a spatula against the spinach.
• To assemble, layer half of sausage in baking dish. Top with 1/3 of cheese. Add mushroom mixture, then 1/3 of cheese. Add spinach, then rest of cheese, then rest of sausage.

• Casserole can be refrigerated overnight at this point.
• Bake at 350 for 30 minutes, until center is set. Cool for 10 minutes before cutting.

Steps:

• Preheat oven to 425°F. Toast bread on a rimmed baking sheet until dry, 8-10 minutes.
• Meanwhile, heat a large skillet over medium-high. Add sausage and cook, breaking into pieces with a spatula, until browned, about 7 minutes.
• Butter a 3-quart baking dish. Arrange 6 bread slices in dish in one layer, covering bottom of pan completely and cutting slices to fit if needed. Tear remaining slice into smaller pieces to fill in any gaps.
• Using a slotted spoon, transfer sausage to baking dish, scattering over bread.
• Heat skillet over medium and add white and pale green scallion parts. Cook, stirring, until softened and just starting to take on color, about 3 minutes. Add spinach, stir to combine, and cook until warmed through, 1-2 minutes more. Top sausage with spinach mixture, then top spinach mixture with cheese.
• Whisk eggs, milk, yogurt, mustard powder, salt, pepper, and nutmeg in a large bowl. Gently pour over casserole. Cover and chill at least 4 hours or up to overnight.
