Main Ingredients
- 3 day-old everything bagels, cut into bite-size pieces (about 6 cups)
- 1 bell pepper, chopped
- 3/4 cup (113g) quartered cherry tomatoes (or chopped regular tomato)
- 6 slices cooked bacon, chopped
- 9 large eggs
- 1 and 1/2 cups whole milk
- 1 and 1/2 cups shredded cheese (such as cheddar or a blend)
- 1/2 teaspoon ground mustard
- 1/4 teaspoon salt
- 1/8 teaspoon freshly ground black pepper
- 6 ounces (170g) full-fat brick cream cheese, cut into bite-size pieces
Optional Garnishes
- Everything bagel seasoning
- Scallions, sliced
Instructions
- Preheat and prepare baking dish. Preheat your oven to 375°F (191°C). Generously grease a 9×13-inch (about 3-quart) baking pan or casserole dish to prevent sticking.
- Layer the base ingredients. Arrange the bite-sized everything bagel pieces evenly in the prepared dish. Scatter the chopped bell pepper, quartered cherry tomatoes, and cooked, chopped bacon over the bagels.
- Mix and add the egg custard. In a large bowl, whisk together the eggs, whole milk, shredded cheese, ground mustard, salt, and freshly ground black pepper until smooth and combined. Pour this egg mixture evenly over the layered bagels and vegetables in the baking dish.
- Add cream cheese and seasoning. Distribute the bite-sized pieces of full-fat cream cheese evenly over the top. Optionally, sprinkle everything bagel seasoning over the entire casserole for an extra burst of flavor.
- Bake the casserole. Place the dish in the preheated oven and bake for 40 to 50 minutes, or until the center is set and the edges turn golden brown and bubbly.
- Cool and garnish. Remove the casserole from the oven and let it cool for 10 minutes. Then, garnish with sliced scallions if desired, slice into portions, and serve warm.
- Store leftovers. Cover any leftover casserole tightly and refrigerate for up to 1 week, reheating as needed.
Notes
- Using day-old bagels helps them hold their shape and absorb the custard without becoming too soggy.
- You can substitute the bell pepper and tomatoes with other veggies like spinach, mushrooms, or onions based on preference.
- For a lower-fat option, use reduced-fat milk and cheese, and turkey bacon instead of regular bacon.
- Everything bagel seasoning adds a wonderful savory crunch but can be omitted if unavailable or for a milder flavor.
- This casserole can be prepared the night before; assemble it and refrigerate, then bake in the morning.
