Ingredients
For the Casserole:
- 4 everything bagels, torn or cut into 1-inch pieces (preferably day-old)
- 1 (8 oz) block cream cheese, cut into small cubes
- 1 1/2 cups shredded cheddar cheese
- 6 large eggs
- 2 cups whole milk
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- 1/2 tsp salt (adjust depending on saltiness of bagels)
- Black pepper, to taste
- 2 tbsp chopped green onions (optional)
For the Topping:
- 1 tbsp Everything Bagel Seasoning (store-bought or homemade)
Instructions
1. Prep the Bagels & Filling
Grease a 9×13-inch baking dish. Spread half the bagel pieces in the bottom. Distribute cream cheese cubes and half the shredded cheddar over top. Add the rest of the bagels and remaining cheddar.
2. Make the Egg Custard
In a large bowl, whisk together eggs, milk, garlic powder, onion powder, salt, and pepper. Pour evenly over the bagel mixture. Press down lightly to help absorb.
3. Chill Overnight
Cover with foil and refrigerate at least 6 hours or overnight.
4. Bake
Preheat oven to 350°F (175°C). Let casserole sit at room temp for 20 minutes. Sprinkle with Everything Bagel Seasoning. Bake uncovered for 40–45 minutes or until golden brown and set in the center.
5. Serve
Cool slightly before slicing. Garnish with green onions if desired. Serve warm.
