1

Grease a 9x13-inch pan. Arrange the brioche cubes in an even layer in the prepared pan.
2

Cook the bacon in a skillet over medium heat, stirring occasionally, until cooked through, about 10 minutes. Remove from the heat with any rendered bacon fat and let it cool slightly, about 5 minutes.
3

Heat a small amount of bacon fat in the same skillet over medium-high heat. Saute the onion and bell pepper until soft, 5 to 7 minutes.
4

Meanwhile, beat the eggs in a large bowl.
5

Stir the milk, Cheddar cheese, mustard powder, pepper, and salt into the beaten eggs.
6

Mix in the bacon and the onion-bell pepper mixture when done.
7

Carefully pour the egg mixture over the brioche bread cubes and gently stir so everything is evenly distributed.
8

Gently press the cubes into the egg mixture as needed so all the bread cubes are submerged in the liquid.
9

Cover and refrigerate for 8 hours to overnight.
10

Preheat the oven to 350 degrees F (175 degrees C).
11

Bake in the preheated oven on the middle rack until set, the top is browned, and a toothpick inserted into the center of the casserole comes out clean, 45 to 55 minutes.
12

Remove from the oven and let cool slightly before serving, 5 to 10 minutes.
