Ingredients and Variations

BREAD: Panettone has been referred to as a cake and a bread, but we love it for French toast. It is dense and often studded with raisins, dried fruit, and nuts making it extra festive and extra flavorful. Other breads that work well for French toast are brioche, challah, or even thick slices of store bought French bread. Gluten-free breads will work if they are very dense so they can absorb the custard mixture without falling apart. Cube bread, as in this recipe, or slice it for a different version.

EGG MIXTURE: Milk can be replaced with half and half but avoid heavy whipping cream as it will be too heavy in the bread. For a festive twist, replace half the milk with eggnog and add some pumpkin spice, or a pinch of nutmeg. Add about half a block of softened cream cheese to the milk mixture to get a creamier custard.

TOPPING: Hold on to the ingredients and instructions for the streusel topping to use for future French toast, muffins, or quick breads! Add some toasted coconut or chopped pecans to the streusel, if desired.
