How to Make Easy French Toast Brioche Casserole with Cinnamon Sugar Croutons
Follow these simple steps to prepare this delicious Easy French Toast Brioche Casserole with Cinnamon Sugar Croutons:
Step 1: Prepare the Bread
Cut the brioche bread into 0.75 to 1-inch thick slices, then into cubes. If using fresh bread, preheat your oven to 250°F (120°C) and let the bread cubes dry out for about 15 to 20 minutes until they feel slightly firm.
Step 2: Make the Custard
In a large jug or blender, combine the half and half, eggs, cornstarch, brown sugar, sea salt, vanilla extract, lemon zest, and if you like, ground cinnamon and nutmeg. Blend until you achieve a smooth consistency that smells absolutely divine.
Step 3: Mix the Casserole
Butter a 4 qt casserole dish generously. Add the dried (or slightly stale) bread cubes evenly across the bottom. Then, pour the custard mixture over the bread, making sure to gently fold the cubes until they soak up all that delicious custard.
Step 4: Refrigerate the Casserole
Cover the casserole dish with plastic wrap or aluminum foil and refrigerate it for at least 4 hours, or up to 24 hours if you really want to impress your guests with your meal prep skills.
Step 5: Prepare the Croutons
In a saucepan over medium heat, melt the butter, adding in the salt and brown sugar until smooth. Mix in the cinnamon, stirring well. Toss the remaining brioche bread cubes in the buttery mixture until they’re well coated.
Step 6: Bake the Casserole
Preheat your oven to 350°F (180°C). Remove the casserole and the croutons from the fridge, then sprinkle the croutons evenly on top of the casserole. Bake for 50 to 60 minutes, or until a thermometer reads 160°F or higher and the top is golden brown.
Let it sit for a few moments before serving so it firms up nicely. Each bite will be a heavenly mix of crunchy croutons and soft, custardy brioche that will create an explosion of flavors you won’t want to miss. Enjoy!
