Ingredients (Serves 6-8)
For the Casserole:
- 4 everything bagels, torn into bite-sized pieces
- 8 large eggs
- 1 ½ cups milk (whole or 2% for creaminess)
- ½ cup heavy cream (for extra richness)
- 1 tsp garlic powder
- ½ tsp black pepper
- ½ tsp salt (adjust depending on saltiness of bagels)
- 4 oz cream cheese, cut into small cubes
- ½ cup shredded cheddar or Swiss cheese
- 6 oz smoked salmon, torn into bite-sized pieces
- 2 tbsp capers, drained
- ½ small red onion, thinly sliced
- 2 tbsp chopped fresh dill
For Topping:
- 1 tbsp everything bagel seasoning
- ½ cup chopped cherry tomatoes (optional)
- Extra dill and capers for garnish
Step-by-Step Instructions
1. Prep Your Dish
- Grease a 9×13-inch baking dish with butter or nonstick spray.
2. Assemble the Base
- Scatter the torn bagel pieces evenly across the dish.
- Dot the cream cheese cubes throughout the bagels so they melt into pockets of creaminess.
- Sprinkle the shredded cheese on top.
3. Mix the Egg Mixture
- In a large bowl, whisk together the eggs, milk, heavy cream, garlic powder, black pepper, and salt.
- Pour the mixture evenly over the bagels, pressing down lightly so the bread absorbs the liquid.
4. Add the Toppings
- Scatter the smoked salmon, red onion slices, and capers evenly over the casserole.
- Sprinkle everything bagel seasoning on top.
5. Refrigerate (Overnight Option)
- Cover the dish with foil and refrigerate for at least 2 hours, or ideally overnight. This helps the bagels absorb the liquid for the best texture.
6. Bake to Perfection
- Preheat oven to 375°F (190°C).
- Bake uncovered for 35-40 minutes, until the top is golden and the center is set.
7. Garnish & Serve
- Let cool for 5-10 minutes before serving.
- Top with chopped fresh dill, extra capers, and cherry tomatoes for extra flavor.
Tips for Success
✔ Use day-old bagels for better texture—slightly stale bagels soak up the egg mixture perfectly.
✔ Swap out the salmon for crispy bacon or turkey sausage if you prefer.
✔ Make it dairy-free by using almond milk and dairy-free cream cheese.
✔ Want extra crunch? Add a handful of toasted sesame seeds before baking.
