Step‑by‑Step Instructions for Everything Bagel Make Ahead Breakfast Casserole
Step 1: Prepare the Dish
Begin by greasing a 13×9 inch casserole dish with butter or nonstick spray, ensuring the base is well coated to prevent sticking. This initial step is crucial for achieving that perfect golden crust on your Everything Bagel Make Ahead Breakfast Casserole. Set the dish aside as you prep the ingredients.
Step 2: Layer Ingredients
Cube half of the everything bagels and spread them evenly across the bottom of the casserole dish. Next, sprinkle half of the crispy bacon followed by half of the Gruyere cheese, and dollop half of the cream cheese in small pieces. Repeat this layering with the remaining bagel cubes, bacon, Gruyere, and cream cheese until all ingredients are used.
Step 3: Mix Wet Ingredients
In a separate large mixing bowl, whisk together the eggs, heavy cream, salt, and pepper until smooth and well combined. This rich mixture will soak into the layers of your Everything Bagel Make Ahead Breakfast Casserole, binding everything together beautifully. Ensure there are no lumps for the smoothest texture.
Step 4: Combine
Pour the egg mixture evenly over the layered bagel ingredients in the casserole dish. Press down gently on the layers to ensure every piece is coated and soaked with the egg mixture. This step helps the casserole set perfectly during baking, allowing all flavors to meld wonderfully.
Step 5: Refrigerate
Cover the casserole tightly with plastic wrap or aluminum foil and refrigerate for a minimum of 4 hours or preferably overnight. This resting period allows the bagels to absorb the egg mixture fully, resulting in a more flavorful and cohesive Everything Bagel Make Ahead Breakfast Casserole when baked.
Step 6: Bake
Preheat your oven to 350°F (175°C) while the casserole is resting. Once preheated, remove the cover and bake the casserole for 40 minutes, then uncover and bake for an additional 15 minutes until the top is golden brown and slightly crisp. You’ll know it’s done when it’s bubbling around the edges and the center is set.
Step 7: Cool and Serve
Once baked, let the casserole cool for about 10 minutes before slicing to facilitate easier serving and enhance flavor. Garnish each slice with freshly chopped chives, which will add a bright touch to your Everything Bagel Make Ahead Breakfast Casserole. Serve warm and enjoy the comforting layers of this delicious breakfast masterpiece.

If you find your casserole is too soggy, this can often happen if the bagels are very fresh or you added too much egg mixture.
