How to Make Everything Bagel Breakfast Casserole
This Everything Bagel Breakfast Casserole is incredibly easy to make, delivering a burst of irresistible flavor and satisfying texture in every bite. The simple combination of toasted bagel pieces, savory sausage, and a creamy egg mixture baked to golden perfection makes it a stand-out dish. With a brief prep and bake time, it’s the ideal solution for any meal.
Step-by-Step Instructions
- Brown the Sausage: In a large skillet over medium heat, cook the breakfast sausage, breaking it up with a spoon, until it is browned and cooked through. If there is excess grease, carefully drain it off, leaving a small amount in the skillet for flavor.
- Prepare the Bagels: While the sausage is cooking, cut the everything bagels into 1-inch cubes. Place these cubes in a large mixing bowl. If your bagels are very fresh and soft, you can lightly toast them in a toaster oven or under the broiler for a few minutes to give them a bit more structure and prevent them from becoming too soggy.
- Whisk the Egg Mixture: In a separate medium bowl, whisk together the large eggs, milk, salt, and black pepper until well combined and slightly frothy. This forms the creamy base of your casserole.
- Assemble the Casserole: Add the crumbled, cooked breakfast sausage to the bowl with the cubed bagels. If you are using red onion, add it now as well. Pour about half of the egg mixture over the bagel and sausage mixture and toss gently to coat.
- Layer the Cheese: Grease a 9×13 inch baking dish with the butter. Spread half of the coated bagel and sausage mixture evenly in the bottom of the prepared baking dish. Sprinkle half of the shredded cheddar and half of the shredded Monterey Jack cheese over this layer.
- Continue Layering: Top the cheese layer with the remaining bagel and sausage mixture. Pour the rest of the egg mixture evenly over the top, ensuring all the bagel pieces are moistened. Sprinkle the remaining cheddar and Monterey Jack cheese over the entire casserole.
- Bake the Casserole: Preheat your oven to 350°F (175°C). Cover the baking dish loosely with aluminum foil and bake for 25 minutes.
- Uncover and Finish Baking: After 25 minutes, carefully remove the aluminum foil. Continue to bake for another 20-25 minutes, or until the casserole is set in the center, the cheese is melted and golden brown, and the top is lightly browned. A knife inserted into the center should come out clean.
- Garnish and Serve: Once baked, remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows it to set up further. Garnish with fresh chives or green onions before cutting into squares and serving warm.

Storing and Reheating Tips
Properly storing and reheating your Everything Bagel Breakfast Casserole ensures you can enjoy its deliciousness for days.
- Refrigeration: Allow the casserole to cool completely after baking. Cover the baking dish tightly with plastic wrap or transfer portions into airtight containers. Refrigerated, the casserole should stay fresh for up to 3-4 days.
- Reheating in Oven: For the best results, reheat individual portions or the entire casserole (if not completely finished) in a preheated oven at 350°F (175°C). Cover loosely with foil for the first 15-20 minutes to prevent drying out, then remove the foil and bake for another 5-10 minutes, or until heated through and the cheese is re-melted.
- Reheating in Microwave: For a quicker option, place a serving in a microwave-safe dish. Microwave on medium power in 30-second intervals, stirring or turning the portion halfway, until heated through. Be mindful that microwaving can sometimes affect the texture of the bagel pieces.
- Freezing: To freeze, let the casserole cool completely. You can freeze the entire dish or individual portions (wrapped well). For individual portions, allow them to freeze solid on a baking sheet before transferring to a freezer-safe bag or container. Frozen casserole can be kept for up to 2-3 months. Thaw overnight in the refrigerator before reheating in the oven or microwave.
