Just leave the casserole on the counter for at least 30 minutes before baking.

- 12 slices (about 1-lb) brioche bread - cubed into 1-inch cubes
- ½ lbs bacon (use more bacon if you desire) - cut into 1-cm pieces
- 8 medium eggs
- 1 ¼ cup whole milk
- 1 cup grated cheddar cheese
- ½ teaspoon ground black pepper
- ½ teaspoon salt
- 2 whole green onions (white and green parts) - sliced thinly, for topping
- Grease a 9x13-inch pan. Evenly layer in the brioche bread cubes.
- In a medium skillet, cook the bacon over medium heat, stirring occasionally, until it is cooked through. Remove from heat, including any rendered bacon fat, and allow to cool slightly.
- As the bacon is cooking, in a large bowl, beat the eggs. Mix in the milk, cheese, pepper and salt. Mix in the bacon when it is done.
- Carefully pour the egg mixture over the brioche bread cubes and give it a gentle stir so everything is evenly distributed. Gently press the cubes into the egg mixture as needed, so all the bread cubes are sitting in the liquid.

- When you are ready to bake the casserole, preheat the oven to 350°F / 180°C. Bake the casserole in the middle oven rack for 45 - 55 minutes, until the middle of the casserole is set, and the top has browned. A toothpick inserted in the middle of the casserole should come out clean.
- Remove the casserole from the oven and allow to cool slightly. Garnish with green onions and serve warm.
