Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
455 g brioche bread
540 mL half and half or full cream milk
25 g cornstarch
7 large eggs
100 g brown sugar
½ tsp sea salt
1 tbsp vanilla extract
1 tsp lemon or lime zest
½ tsp ground cinnamon (optional)
½ tsp nutmeg (optional)
225 g brioche bread
125 g unsalted or salted butter
150 g brown sugar
1 tsp ground cinnamon
¼ tsp salt
Directions
Start by cutting the brioche into cubes about 0.75 to 1 inch in size. If the bread is fresh, dry it in a low oven until slightly firm.
Prepare the custard by blending or whisking together the milk, eggs, brown sugar, cornstarch, salt, vanilla, and zest until smooth and lump-free.
Grease a casserole dish and spread the bread cubes evenly. Pour the custard over the bread, gently fold, and press down so all pieces absorb the mixture.
Cover and refrigerate for at least 4 hours or overnight for best results.
To make the cinnamon toast croutons, melt butter with sugar and salt, then mix in cinnamon. Toss additional bread cubes in this mixture until fully coated.
Preheat the oven to 180°C. Spread the croutons evenly over the soaked casserole.
Bake for 50 to 60 minutes until the center is set and reaches about 160°F internally. If the top browns too quickly, cover loosely with foil.
Let the casserole rest briefly before serving so the topping becomes crisp.

Variations
You can add fresh berries or sliced bananas between the bread layers for a fruity twist. Chocolate chips can be mixed in for a dessert-style version. For a nutty crunch, sprinkle chopped pecans or walnuts into the topping. You can also swap brioche with challah or croissants for slightly different textures and flavors.
Storage/Reheating
Store leftovers covered in the refrigerator for up to 3 days. To reheat, place portions in the oven at 160°C until warmed through, or microwave individual servings for a quicker option. For best texture, reheating in the oven helps maintain the crispy topping.

Ingredients
- 455 g brioche bread, cubed
- 540 mL half and half (or full cream milk)

- 150 g brown sugar (for topping)
- 1 tsp ground cinnamon (for topping)
- 1/4 tsp salt (if using unsalted butter)
Instructions
- Cut brioche into 0.75–1 inch cubes. If fresh, dry in a 250°F (120°C) oven for 15–20 minutes, then cool.
- Prepare custard by blending milk, cornstarch, eggs, sugar, salt, vanilla, zest, and optional spices until smooth.
