Overnight Everything Bagel Breakfast Casserole Recipes

Steps:

• Spray a 9-by-13-inch baking dish with nonstick cooking spray. Spread the bagel chunks in the dish in an even layer, then dollop the cream cheese around the baking dish, on top of and in between the bagel chunks.
• In a large bowl, whisk together the milk, eggs, garlic powder, salt, pepper, half the red onion and half the chives until combined. Pour the mixture over the bagels in the baking dish. Cover the baking dish with foil and refrigerate overnight.
• Preheat the oven to 350 degrees F. Set the baking dish out at room temperature while the oven heats.
• Bake, still covered in foil, until mostly set, about 1 hour. Remove the foil and bake until the top is lightly browned, 10 to 15 minutes more. Let cool slightly for 10 to 15 minutes. Garnish the top with ribbons of smoked salmon, capers and the remaining red onion and chives. Serve immediately.

Steps:

• Position a rack in the center of the oven and preheat to 350 degrees F. Grease a 9-by-13-inch baking dish with butter or cooking spray.
• Heat the olive oil in a large skillet over medium high heat. Add the sausage and cook, breaking up any clumps with a wooden spoon, until brown, about 5 minutes; transfer to a bowl with a slotted spoon.
• Whisk together the milk, half-and-half, cayenne, eggs, 3/4 teaspoon salt and 1/2 teaspoon pepper in a large bowl. Fold in the sausage, spinach, bagels and 3/4 cup of the provolone, then pour into the prepared baking dish. Dot the top with the cream cheese and sprinkle all over with the everything bagel seasoning and remaining provolone (see Cook's Note).
• Cover with foil and bake for 45 minutes. Uncover and bake until the casserole is puffed, golden brown at the edges and set in the center, about 45 minutes more. Let cool 15 minutes before serving.
