This Everything Bagel Breakfast Casserole screams comfort, is packed with flavor, and is sure to be a new favorite in your household. Just like my Breakfast Sliders, Breakfast Enchiladas, and my Breakfast Sausage Casserole.
If you’ve been looking to elevate your breakfast game, this casserole is it. It’s easy to make and the most delicious crowd-pleasing breakfast or brunch option for weekday mornings, lazy weekends, holiday entertaining, or something to look forward to for meal-prep.
The bagels work so well in this recipe. Their crunchy exterior adds a satisfying texture to this casserole and when baked, the bagel cubes soak up the egg mixture while maintaining their chewy texture, creating a delicious contrast in each bite. Ugh, it’s just the best!
Why this recipe works
- So much flavor!: The star of this dish is the everything bagel, with its delicious combination of sesame seeds, poppy seeds, garlic, onion, and salt. These flavors complement the creamy eggs and cheese, making each bite flavorful.
- Customizable: Want to add meat? Toss in some sausage or bacon. Prefer a vegetarian version? Add extra veggies like spinach, mushrooms, or peppers. The possibilities are endless!
- Easy to Make: This is a great “throw-together” dish for busy mornings. Prep it the night before and pop it in the oven in the morning for a hassle-free breakfast.
- Perfect for Groups: Whether you’re hosting a brunch or making breakfast for the family, this casserole is a great way to feed a crowd without much effort.
Ingredient Notes
(For the full recipe, scroll down to the recipe card below)
- Everything bagels: The star of the show! These bagels give the casserole its signature flavor. See my expert tips below about the bagels.
- Eggs: The base of the casserole, providing fluffiness and structure. I recommend using large eggs.
- Cheese: Feel free to use a combination of your favorite cheeses: Cheddar, Mozzarella, Swiss, Gruyère, or pepper jack for more complexity.
- Cream cheese: Cut the cream cheese into small cubes so that you get pockets of creamy goodness throughout the casserole. You can use flavored cream cheese (like chive or veggie) for extra flavor.
- Everything But The Bagel Seasoning: If you want to enhance the everything bagel flavor, sprinkle a bit of extra everything bagel seasoning on top before baking and after baking/before serving.
- Cherry Tomatoes: I like to roast the tomatoes first, I love the color they add to the casserole.
- Other ingredients needed: olive oil, salt, pepper, Dijon mustard, cayenne, and green onions.
Step by Step Directions

Roast the tomatoes
Toss the cherry tomatoes on a baking sheet lined with foil with the olive oil salt and pepper and cook for ~25-30 minutes.
Whisk together egg mixture
The eggs, cheese, milk, heavy cream, dijon, salt and pepper! So far so good, ya?!
20 min. soak (or overnight!)
Bake!
Dot cream cheese pieces over the top and sprinkle everything but the bagel seasoning all over, bake until set, then enjoy!
Expert Tips
- Use day-old or slightly stale everything bagels if possible, as they absorb the egg mixture better without getting too soggy. If you only have fresh bagels, you can toast them briefly before adding them to the casserole.
- Grate the cheese fresh from a block yourself, it will melt better and make for a better tasting casserole, too.
- Make-Ahead Friendly: This casserole can be prepared the night before and baked in the morning, making it perfect for a stress-free breakfast or brunch.
Variations
- Different veggies: Diced onions, bell peppers, or spinach are great additions for extra flavor and nutrition. Sauté them briefly to soften before adding them to the casserole, so they blend well with the egg mixture.
- Add meat: feel free to add sausage, bacon, or ham; just make sure to cook and drain the meat beforehand to avoid excess grease in the casserole. These proteins add extra flavor and make the dish even more yummy.
- Lox Bagel Casserole: Incorporate smoked salmon, capers, and red onion for a lox-inspired version. Add dill for extra flavor!
Storage
- Cool completely and store in the fridge for 3-4 days. Reheat in the microwave until warmed through.
