Easy Cheesy Everything Bagel Breakfast Casserole

Easy Cheesy Everything Bagel Breakfast Casserole - featured image

A quick and easy breakfast casserole featuring everything bagels, eggs, and a blend of cheddar and mozzarella cheeses, perfect for busy mornings or weekend brunch.

Ingredients

Scale
  • 4 medium-sized everything bagels, cut into 1-inch cubes
  • 6 large eggs, room temperature
  • 1 ½ cups (360 ml) whole milk
  • 2 cups (200 g) shredded sharp cheddar cheese
  • 1 cup (100 g) shredded mozzarella cheese
  • 2 stalks green onions, thinly sliced
  • 2 tablespoons everything bagel seasoning
  • Salt and black pepper, to taste
  • 1 tablespoon unsalted butter, for greasing the baking dish

Instructions

  1. Preheat your oven to 350°F (175°C). Grease your baking dish thoroughly with butter.
  2. Cube the bagels into roughly 1-inch pieces and spread them evenly in the greased baking dish.
  3. In a medium bowl, whisk together the eggs and milk until fully combined and slightly frothy, about 1-2 minutes. Add salt and black pepper to season.
  4. Stir in the shredded cheddar and mozzarella cheese along with the thinly sliced green onions.
  5. Pour the egg and cheese mixture evenly over the bagel cubes, pressing down lightly with a spatula to ensure the bagels soak up the custard well.
  6. Sprinkle the everything bagel seasoning generously over the top.
  7. Bake uncovered for 35-40 minutes, or until the casserole is set and golden brown on top. Test doneness by inserting a knife in the center; it should come out clean.
  8. Remove from oven and let it rest for 5-10 minutes before slicing and serving.

Notes

Let the bagel cubes soak in the egg mixture for at least 5 minutes before baking to ensure a moist, creamy center. Butter the baking dish well to prevent sticking. If the top browns too quickly, tent with foil halfway through baking. This casserole can be assembled the night before and baked fresh in the morning.
