Yield: 1 (8×8-inch) casserole
Ingredients
- 5 cups French bread, cut into cubes
- 1 ½ cups milk
- 4 large eggs
- ¼ cup granulated sugar, divided
- ¼ teaspoon salt
- 1 teaspoon vanilla extract
- 1 tablespoon butter, softened
- 1 teaspoon ground cinnamon
Directions
- Preheat oven to 350°F (175°C). Lightly grease an 8×8-inch baking dish.
- Spread the bread cubes evenly across the bottom of the prepared dish.
- In a large bowl, whisk together milk, eggs, 2 tablespoons of the sugar, salt, and vanilla extract until smooth and fully combined.
- Pour the custard mixture evenly over the bread cubes, gently pressing down to help the bread absorb the liquid. Dot the top with small pieces of butter.
- Let the mixture sit for about 15 minutes so the bread can soak up the custard.
- In a small bowl, mix the remaining 2 tablespoons of sugar with the cinnamon. Sprinkle evenly over the top.
- Bake for 45 to 50 minutes, or until the center is set and the top is golden brown.
- Remove from oven and let cool slightly before serving. Serve warm with maple syrup or fresh fruit.
Chefs Notes
- Day-old bread works best since it absorbs more of the custard without becoming soggy.
- For a richer flavor, substitute brioche or challah for the French bread.
- This casserole can be assembled the night before—just cover tightly and refrigerate, then bake in the morning.
- To reheat leftovers, use the oven instead of the microwave to maintain the best texture.
