Ingredients
- Everything Bagels (5): Everything bagels are the backbone of this casserole. Their dense, chewy texture contrasts beautifully with the creamy egg mixture, making each bite satisfying. The bagels are cut into cubes and soaked in the egg mixture, allowing them to become tender while still holding their shape. The “everything” seasoning on the bagels—typically a mixture of sesame seeds, poppy seeds, garlic, onion, and salt—adds a savory, slightly garlicky flavor that permeates the casserole, infusing it with a distinctive breakfast essence.
- Bacon (8 ounces): Crispy, salty bacon adds a savory crunch that contrasts with the softness of the eggs and bagels. Bacon’s smoky flavor enhances the richness of the dish and provides a savory counterpoint to the mildness of the bagels and cheese. The bacon should be cooked and diced before being added to the casserole, ensuring it distributes evenly throughout the dish.
- Gruyère Cheese (2 cups): Gruyère is a fantastic choice for a breakfast casserole because of its meltability and nutty flavor. When baked, it melts beautifully and creates gooey pockets of cheese that add richness and depth to the casserole. The slight nuttiness of Gruyère complements the bacon and the creamy eggs, making it the perfect pairing for this dish. If Gruyère isn’t available, Swiss cheese is a great substitute, but the flavor will be a bit milder.
- Cream Cheese (8 ounces): Cream cheese adds a rich, smooth texture to the casserole. When cubed and layered throughout the dish, it melts into the eggs, creating pockets of creaminess that add another layer of richness. The tangy flavor of cream cheese balances the richness of the eggs and the cheese, giving the casserole a slight bite that offsets the otherwise creamy consistency.
- Eggs (8 large): Eggs are the essential binding element of this casserole. They transform the dish from a collection of bagels, bacon, and cheese into a cohesive, custardy bake. The eggs add moisture and create the perfect soft texture that contrasts with the crisp bacon and the chewy bagel cubes. For a creamier texture, you can even use a mix of whole eggs and egg whites to suit your preferences.
- Heavy Cream (2 cups): Heavy cream gives the egg mixture its richness and provides a velvety texture to the casserole. The fat from the cream ensures that the casserole has a luxurious mouthfeel, making each bite feel decadent. If you want a lighter version, you can substitute part of the cream with milk, but the richness of the heavy cream is key to achieving that creamy, indulgent consistency.
- Salt (½ teaspoon) and Pepper (¼ teaspoon): Seasoning is crucial to balance the richness of the eggs and cheese. The salt and pepper bring out the flavors of the bacon, cheese, and bagels, ensuring that each bite is flavorful and well-seasoned.
- Chives (for garnish): Fresh chives add a pop of color and a mild onion flavor to the casserole, making it more visually appealing and enhancing the overall flavor with a touch of freshness. Chives are optional but highly recommended as a garnish to round out the dish.
Instructions
- Grease the casserole dish: Start by greasing a 13×9-inch casserole dish with butter or cooking spray. This will ensure that the casserole doesn’t stick and makes for easier cleanup.
- Layer the bagels and other ingredients: Begin by layering half of the cubed everything bagels in the casserole dish. Spread them out evenly across the bottom. Then, layer half of the cooked and crumbled bacon on top of the bagels, followed by half of the shredded Gruyère cheese and half of the cubed cream cheese. This layering process ensures that every bite will have a perfect balance of bagels, bacon, and cheese. Repeat with the remaining bagels, bacon, Gruyère, and cream cheese.
- Prepare the egg mixture: In a large bowl, whisk together the eggs, heavy cream, salt, and pepper until everything is well combined. The cream should help give the eggs a smooth, rich texture. Pour this mixture evenly over the bagel layers, making sure the egg mixture soaks into all the bagels.
- Refrigerate the casserole: Tightly cover the casserole dish with plastic wrap or aluminum foil and refrigerate it for at least 4 hours, or overnight if you have the time. This step allows the bagels to soak up the egg mixture, resulting in a fluffy, custard-like texture when baked.
- Bake the casserole: When you’re ready to bake, preheat your oven to 350°F (175°C). Bake the casserole, covered with foil, for 40 minutes. After 40 minutes, remove the foil and continue baking for an additional 15 minutes to allow the top to become golden brown and crispy.
- Cool and garnish: Once the casserole is done baking, allow it to cool for about 10 minutes. This resting time ensures the casserole firms up slightly and is easier to slice. Garnish with fresh chives for added flavor and a touch of color before serving.
Notes
- Cheese Variations: Gruyère is a flavorful, meltable cheese that works beautifully in this casserole, but if you prefer a different type of cheese, consider swapping it for cheddar, Monterey Jack, or Swiss. Each cheese brings a slightly different flavor profile, so feel free to experiment with what you like best.
- Bacon Alternatives: If you’re looking for a lighter option, you can substitute the bacon with turkey bacon, which will still provide a crispy texture and smoky flavor. For a vegetarian version, simply leave out the bacon entirely and add other savory vegetables like sautéed mushrooms or spinach.
- Bagel Varieties: Everything bagels are the obvious choice for this casserole, but you can experiment with different bagel flavors, such as onion bagels or even plain bagels for a simpler version. You could also try whole grain or gluten-free bagels to cater to different dietary needs.
- Add-ins: For extra flavor, consider adding sautéed onions, garlic, or bell peppers to the casserole. These ingredients will add a subtle sweetness and depth to the dish that complements the richness of the cheese and eggs.
