When it comes to comforting, all-in-one breakfast dishes, few recipes deliver like a Loaded Everything Bagel Bake. It’s everything you love about a savory breakfast — bagels, eggs, cheese, and bacon — baked into one irresistible, golden casserole.

Perfect for busy mornings, lazy weekends, or brunch gatherings, this make-ahead dish combines fluffy eggs, chewy bagel bites, crispy bacon, and creamy cheese in every forkful. The everything bagel seasoning adds that signature pop of garlic, onion, sesame, and salt, making this casserole bold and addictive from the first bite.

It’s cozy, satisfying, and easy to prepare — exactly what a great breakfast bake should be.

Why You’ll Love This Everything Bagel Bake

Unlike standard breakfast casseroles, this version uses toasted everything bagels for a rich, chewy texture and a boost of savory flavor. Each piece soaks up the egg custard while staying slightly crisp around the edges, giving you a perfect mix of soft and crunchy in every bite.

In addition, the cream cheese melts into little pockets of tangy richness, while the bacon and cheddar bring a smoky, salty balance. It’s a one-pan breakfast masterpiece that practically makes itself.

Ingredients List

For the Casserole:

4 everything bagels, cut into 1-inch cubes
8 large eggs
2 cups whole milk
1 cup shredded sharp cheddar cheese
4 oz cream cheese, cut into small cubes
6 slices cooked bacon, crumbled
1 teaspoon everything bagel seasoning, plus extra for topping
1 teaspoon Dijon mustard
½ teaspoon garlic powder
½ teaspoon onion powder
Salt and black pepper, to taste
2 tablespoons butter, for greasing the baking dish

Optional Toppings:

Chopped green onions or chives
Extra shredded cheese
Sour cream or hot sauce, for serving

Step-by-Step Instructions

Step 1: Toast the Bagels

First, preheat your oven to 350°F (175°C). Spread the cubed everything bagels on a baking sheet and toast for 8–10 minutes, until lightly crisp and golden.

This step keeps the casserole from turning soggy and adds an irresistible chew to the final dish.

Step 2: Cook the Bacon

Meanwhile, cook the bacon in a skillet over medium heat until crisp. Drain on paper towels, then crumble into bite-sized pieces. Set aside.

Pro Tip: Save a teaspoon of bacon drippings to brush over the top of the casserole before baking for a richer, smokier flavor.

Step 3: Prepare the Egg Mixture

In a large bowl, whisk together eggs, milk, Dijon mustard, garlic powder, onion powder, salt, and pepper until smooth. The mustard adds a subtle tang that balances the richness of the cheese and bacon.

Step 4: Assemble the Casserole

Grease a 9×13-inch baking dish with butter. Add the toasted bagel cubes, crumbled bacon, cream cheese cubes, and shredded cheddar cheese, mixing gently to distribute evenly.

Slowly pour the egg mixture over the bagel layers, pressing lightly with a spatula so everything soaks evenly.

Sprinkle with everything bagel seasoning on top for that signature texture and flavor.

Step 5: Let It Rest (Optional for Overnight Prep)

If you’re planning ahead, cover the dish tightly and refrigerate overnight. This allows the bagels to absorb the custard completely, creating an even fluffier texture.

Otherwise, let it rest at room temperature for 15–20 minutes before baking to allow partial soaking.

Step 6: Bake Until Golden and Set

Preheat the oven to 375°F (190°C). Bake uncovered for 40–45 minutes, until the top is golden brown, the edges are crisp, and the center is set.

If it begins browning too quickly, cover loosely with foil for the last 10 minutes.

Step 7: Garnish and Serve

Remove from the oven and let the casserole rest for 5–10 minutes before slicing. Sprinkle with chopped chives or extra everything bagel seasoning, and serve warm with sour cream, hot sauce, or fresh fruit on the side.

It’s hearty enough for a full breakfast but also perfect for brunch buffets or breakfast-for-dinner nights.

Flavor Variations

Sausage Lover’s Bake: Swap bacon for cooked breakfast sausage or chorizo for a spicier bite.
Vegetarian Option: Use sautéed mushrooms, spinach, and roasted red peppers instead of meat.
Smoked Salmon Brunch Bake: Add flaked smoked salmon, cream cheese, and red onions for a deli-style twist.
Extra Cheesy: Mix in Monterey Jack or pepper jack for a creamier, richer casserole.

Each variation keeps the comforting base but tailors the flavor to your morning mood.

Storage & Reheating Tips

If you’re lucky enough to have leftovers, this dish reheats beautifully.

Refrigerate: Store in an airtight container for up to 4 days.
Freeze: Wrap tightly in foil or freezer wrap for up to 2 months.
Reheat: Warm individual portions in a 350°F oven for 10–12 minutes, or use the air fryer for crispy edges.

Avoid microwaving for too long, as it can make the bagels rubbery.

Common Mistakes & How to Avoid Them

Skipping the bagel toasting: Leads to a soggy casserole. Toast first for best texture.
Overbaking: Makes the eggs rubbery. Bake only until the center is just set.
Too much salt: Bagel seasoning and bacon are salty enough; taste before seasoning further.
Uneven soaking: Press down the bagels gently after pouring in the egg mixture for even absorption.

Balanced flavor: Creamy, salty, tangy, and perfectly savory.
Great texture: Crispy top, soft center, chewy bagel bites.
Make-ahead friendly: Ideal for prepping the night before brunch.
