Cut croissants into halves or quarters, depending on size, and arrange them evenly in the prepared baking dish.

In a large bowl, vigorously whisk eggs, whole milk, heavy cream, vanilla extract, granulated sugar, and optional lemon zest until smooth and homogeneous.

Slowly pour the custard mixture over the croissants and berries, ensuring all croissant pieces are fully saturated; gently press down to help absorption.

Bake in the preheated oven for 35-40 minutes until the top is deeply golden and the custard is just set with a slight wobble in the center.
