This baked iced lemon french toast is soft, lightly sweet, and finished with a bright lemon drizzle. Perfect for make-ahead brunch or easy weekend mornings.
Lightly spray a 9x13 baking dish and arrange the brioche slices in slightly overlapping rows so they fit snugly in the dish.
In a large bowl, whisk together eggs, milk, lemon zest, vanilla extract, and cinnamon until smooth.
Slowly pour the custard evenly over the bread, making sure to coat each slice.
Let the mixture sit for at least 30 minutes so the custard can absorb, or cover and refrigerate overnight for an easy make-ahead option.
Preheat your oven to 350°F and bake for about 30 minutes, until the tops are lightly golden and the center is set but still soft.
While the french toast is baking, whisk together powdered sugar and fresh lemon juice until smooth and pourable.
Remove from the oven and drizzle the lemon icing over the top while warm, then add a light dusting of powdered sugar if you’d like.
Notes
Add mix-ins like fresh blueberries, strawberries, or even a few dollops of cream cheese for an easy way to switch up the flavor while keeping a lemon base.
Store leftovers in an airtight container in the fridge for up to 3 days and reheat in the oven or air fryer to bring back the best texture.
