- Step-by-Step Method
- I prefer explaining this simply so you never get confused.
Step 1: Prepare the Bread
- Cube the brioche and place it evenly into a greased 9×13 baking dish. Soft breads like brioche or challah absorb better, don’t you think so?

Step 2: Make the Custard
- Whisk eggs, milk, cream, both sugars, vanilla, cinnamon, nutmeg, and salt.
- Pour this mixture slowly over the bread so every cube gets coated.

Step 3: Overnight Soaking
- Cover the dish with cling wrap and refrigerate for 6–8 hours.
- This slow resting helps the custard move inside the bread instead of running out.

- Don’t you love recipes that work while you sleep?
Step 4: Prepare the Topping
- Mix flour, brown sugar, cinnamon, and salt. Add cold cubed butter and crumble it with your fingers.

Step 5: Bake
- Sprinkle the topping evenly on top.
- Bake for 45–50 minutes until puffed, golden, and slightly crisp on top.

Notes
Helpful Recipe Notes
- Overnight soaking gives the casserole the best custard-like texture.
- Brioche or challah works best because they stay soft.
- If you want a softer top, cover with foil for first 25 minutes.
- Make the topping ahead and keep it cold for extra crunch.
- Add fresh berries on top after baking for more flavor.
