Bagel Breakfast Casserole Recipe

 Bagel Breakfast Casserole is a hearty and satisfying dish that turns your favorite morning bagels into a baked breakfast feast. It’s loaded with eggs, cheese, cream cheese, and sausage (or bacon), creating a golden, custardy bake that’s crispy on top and soft inside. Perfect for holidays, brunch gatherings, or a make-ahead breakfast, this casserole brings all the flavors of a classic bagel sandwich — in one easy dish.

Ingredients

  • 4 plain or everything bagels, cut into 1-inch cubes

  • 1 tablespoon butter (for greasing the dish)

  • 1 cup cooked breakfast sausage or chopped bacon

  • 1 cup shredded cheddar cheese

  • ½ cup cream cheese, cut into small cubes

  • 6 large eggs

  • 2 cups milk (whole or 2%)

  • ½ teaspoon salt

  • ¼ teaspoon black pepper

  • ¼ teaspoon garlic powder

  • 2 green onions, thinly sliced (optional for garnish)

Cooking Time

  • Prep time: 15 minutes

  • Cook time: 45 minutes

  • Total time: 1 hour

Serving

  • Serves 6–8

Instructions

  1. Prepare the baking dish:

    Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter.

  2. Assemble the base:

    Place the cubed bagels in the prepared dish. Sprinkle cooked sausage (or bacon), shredded cheddar, and cream cheese cubes evenly over the bagel pieces.

  3. Make the egg mixture:

    In a large bowl, whisk together eggs, milk, salt, pepper, and garlic powder until smooth and frothy.

  4. Combine:

    Pour the egg mixture evenly over the bagel and cheese mixture. Lightly press down with a spatula so everything soaks up the liquid.

  5. Rest or bake immediately:

    For best results, cover and refrigerate for at least 30 minutes or overnight to let the bagels absorb the mixture. If short on time, you can bake it right away.

  6. Bake:

    Uncover and bake for 40–45 minutes, until the top is golden brown and the center is set.

  7. Serve:

    Let the casserole rest for 5 minutes before cutting into squares. Garnish with sliced green onions if desired.

Tips

  • Everything bagels add extra flavor without extra effort.

  • Swap sausage for diced ham, turkey bacon, or vegetables like spinach and mushrooms.

  • For a richer dish, replace ½ cup of the milk with half-and-half.
