Savory Everything Bagel Breakfast Casserole Recipe

Sunday mornings in my house usually mean slow coffee and a hearty breakfast that feeds the whole family. I crave savory flavors over sweet ones, so this bake always hits the spot.

My Everything Bagel Breakfast Casserole brings all the best parts of a deli run into one warm dish. You can prep it the night before and just slide it into the oven when you wake up.

What Makes This Everything Bagel Breakfast Casserole So Special

You get the satisfying chew of a bagel combined with creamy eggs and rich cheese in every bite. It feels like a special occasion meal but requires barely any effort on your part.

The Everything Bagel Breakfast Casserole seasoning adds that signature garlic and onion punch without needing a dozen different spice jars. You will appreciate how easily this adapts to whatever veggies or proteins you have in the fridge.

Feeding a crowd happens effortlessly since everything bakes together in a single pan. I love how the bagels soak up the custard while the top gets perfectly golden and crisp.

Everything You Need for Perfect Everything Bagel Breakfast Casserole

Here’s what you’ll need to get started:

• Bagels: Plain or everything bagels work best here, preferably a day old so they absorb liquid well.
• Turkey Sausage: I use bulk turkey sausage for savory protein, but beef bacon is a great alternative.
• Eggs: Large eggs form the base of the custard to bind the casserole together.
• Milk: Whole milk or half-and-half creates a rich, creamy texture.
• Cream Cheese: A block of cold cream cheese, cubed, creates pockets of tangy goodness.
• Cheddar Cheese: Sharp cheddar adds a nice bite and melts beautifully on top.
• Onion: A yellow or white onion adds sweetness and depth when sautéed.
• Red Bell Pepper: Provides a pop of color and freshness to balance the rich cheese.
• Everything Bagel Seasoning: The essential spice blend that gives this dish its signature flavor profile.
• Butter: Used for greasing the baking dish and sautéing the vegetables.

My Method for Everything Bagel Breakfast Casserole

Let’s get cooking!

1. Grease a 9×13 inch baking dish with butter and set it aside while you prepare the ingredients.
2. Brown the turkey sausage in a large skillet over medium-high heat until fully cooked, breaking it into crumbles as it fries.
3. Add the chopped onion and red bell pepper to the skillet with the sausage, cooking for another 3-4 minutes until softened.
4. Whisk the eggs, milk, salt, and black pepper together in a large bowl until the mixture is completely smooth and uniform.
5. Cut the bagels into 1-inch cubes and spread half of them evenly across the bottom of your prepared baking dish.
6. Layer the cooked sausage and vegetable mixture over the bagels, then top with cubes of cream cheese and half of the cheddar cheese.
7. Add the remaining bagel cubes on top and carefully pour the egg mixture over the entire dish, pressing down slightly to submerge the bread.
8. Sprinkle the remaining cheddar cheese and the Everything Bagel Breakfast Casserole seasoning generously over the top.
9. Cover with foil and refrigerate for at least 1 hour, or overnight, to allow the bread to soak up the custard.
10. Preheat your oven to 375°F (190°C), remove the casserole from the fridge, and bake covered for 25 minutes.
11. Remove the foil and bake for an additional 15-20 minutes until the top is golden brown and the center is set.

My Everything Bagel Breakfast Casserole Secrets

Stale bagels actually work better here because they absorb the egg mixture without becoming mushy. I often buy a bag a few days early and let them sit on the counter.

Ensure you distribute the cubes of cream cheese evenly throughout the Everything Bagel Breakfast Casserole for pockets of tanginess. You want every slice to have that rich contrast against the savory turkey sausage.

Let the dish sit for ten minutes after baking to help the custard set firmly. This simple pause ensures clean slices instead of a runny mess on the plate.

How to Serve This Everything Bagel Breakfast Casserole

Fresh fruit or a simple green salad cuts through the richness of the cheese and eggs perfectly. I like to offer hot sauce on the side for those who want an extra kick with their meal.

A strong cup of coffee or fresh orange juice pairs beautifully with the savory garlic and onion notes. You can also reheat leftovers of this Everything Bagel Breakfast Casserole for a quick lunch during the week.
