You can also get away with preparing this all in the morning. That's because brioche is generally forgiving enough.
If you make this recipe in the morning, there's one important step to take. Give the bread cubes a good poking with a fork before scattering them into the casserole dish.

I need to make this breakfast this morning
It's best to treat this as an overnight Bacon Breakfast Casserole.
But if you're reading this and need to get this in the oven this morning, relax!
Start by following the recipe. However, give your bread cubes a good poking with a fork before pouring in the liquid.
That will help encourage the bread to soak in the egg mixture quicker. If you have the time, just leave the casserole on the counter for at least 30 minutes before baking.
Using brioche bread in this casserole
I love using brioche bread in this casserole. That's because of its richness, slightly sweet taste, and soft texture.
Challah also works great in this make ahead breakfast casserole since the hearty bread goes with the bacon.
I would avoid using sourdough, though.
Adding other ingredients
This is a simple recipe with straight forward flavors. Feel free to add in onions, red or green peppers, and or other mix-ins of your choice.
If you do so, cook the mix-ins with the bacon first. Doing so will rid any excess water. Then, simply mix into the custard.
Here's a delicious seasoning that would work so well as a finishing!

Bacon Breakfast CasserolePrint Recipe Save RecipeSaved!
- 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.
- Cover and let sit for at least 30 minutes, but preferably let the casserole sit in the refrigerator overnight.
- 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.

Do you cover it in the oven?
Can you use anything other than whole milk (2% possibly)?
Tina Jui says
2% should work ok!
We’re going to try it with goat milk
