Preheat the oven to 300°F and grease a large oven-safe casserole dish (10-inch square/round or larger).
In a large bowl, whisk together the eggs, milk, salt, pepper, green onion, dill, and capers until smooth.
14 eggs, 1 cup whole milk, 1/2 to 3/4 cup green onion, 4 tbsp fresh dill, 1/2 tsp salt, 3 tbsp capers, 1 tsp pepper
Tear the brioche into uneven, bite-sized pieces and place in the casserole dish.
1 loaf brioche bread
Pour the egg mixture evenly over the brioche, gently pressing the bread so it absorbs the liquid.
Nestle the brie and smoked salmon throughout the dish, and scatter a few pieces over top.
170 g cold smoked salmon, 172 g brie
Bake for 25 minutes, or until the eggs are just set.
Remove from the oven, finish with garnishes, and serve right away. Enjoy!
