Description

A warm, cheesy breakfast bake made with everything bagels, eggs, milk, and a blend of cheeses, this Everything Bagel Casserole transforms classic bagel flavors into a hearty, crowd-pleasing dish perfect for brunch or make-ahead mornings.


Ingredients

6 everything bagels, cut into bite-sized pieces

8 large eggs

2 1/3 cups whole milk

1/2 teaspoon kosher salt

1/4 teaspoon black pepper

1/4 teaspoon garlic powder

1/2 teaspoon onion powder

3/4 cup shredded cheddar cheese

3/4 cup shredded mozzarella cheese

8 ounces cream cheese, cut into cubes

Fresh chopped green onions, for garnish


Instructions

  1. Preheat the oven to 350°F (175°C) and grease a 9×13-inch baking dish with cooking spray.
  2. Place the bagel pieces evenly in the prepared baking dish.
  3. In a large mixing bowl, whisk together eggs, milk, salt, pepper, garlic powder, and onion powder until combined.
  4. Stir in the shredded cheddar and mozzarella cheese.
  5. Pour the egg mixture evenly over the bagel pieces.
  6. Distribute the cream cheese cubes evenly on top, pressing them gently into the mixture.
  7. Cover the dish with aluminum foil and bake for 30 minutes.
  8. Remove the foil and bake for an additional 20 minutes, until golden brown and set in the center.
  9. Allow the casserole to cool for 10 minutes before slicing.
  10. Garnish with chopped green onions and serve warm.

Notes

Use slightly stale or toasted bagels so they hold up well in the custard.

Sprinkle extra everything bagel seasoning on top before baking for more flavor.

Customize with sautéed veggies like spinach, mushrooms, or bell peppers.

Use half-and-half for an even richer casserole.

Assemble the night before and refrigerate for an easy make-ahead breakfast.
