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.

Equipment
Ingredients
Optional Streusel Topping
- ⅓ cup flour
- ⅓ cup brown sugar
- ¼ cup quick oats
- 2 Tablespoons butter
Instructions
- Grease a 9×13 inch baking dish with butter.
- Cut panettone into ½ inch cubes, removing any hard crust. Add to a large bowl.
- Mix together eggs, milk, sugar, vanilla, and cinnamon.
- Pour egg mixture on top of bread, and very gently toss to coat all pieces. Gently pour into the baking dish and arrange evenly. Cover and refrigerate for 2 hours, or overnight.
To bake:
- Remove baking dish from the refrigerator while the oven preheats. Preheat oven to 350˚F.
- If adding Streusel Topping, mix all ingredients together (use a pastry cutter for ease), (or prepare the night before) and sprinkle over the top of the dish.
- Bake uncovered for 45-60 minutes, or until a knife comes out clean. If the top is getting browned before the dish is baked through, tent loosely with foil for the remainder of cook time.
- Remove from the oven and allow to rest for 5-10 minutes before serving. The dish will puff up while baking, and settle after it’s been out of the oven for a few minutes.
