Step-by-Step Preparation Method

Step 1: Prepare the Bread
Cut the bread into 1-inch cubes. For the best texture, use day-old or slightly stale bread, or lightly toast fresh bread to remove excess moisture.

Step 2: Preheat the Oven
Preheat the oven to 350°F (175°C). Lightly grease a 9 × 13-inch baking dish with butter or nonstick spray.

Step 3: Cook the Cinnamon Apples
Melt butter in a skillet over medium heat. Add diced apples, brown sugar, cinnamon, vanilla, lemon juice, and flour. Cook for 5–7 minutes, until slightly softened, then remove from the heat.

Step 4: Make the Custard
Whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla, cinnamon, nutmeg, and salt until smooth and well combined.

Step 5: Soak the Bread
Place the bread cubes in a large bowl and pour the custard over them. Gently toss to coat, then let the bread soak for 5–10 minutes.

Step 6: Add the First Layer
Spread half of the soaked bread evenly into the prepared baking dish.

Step 7: Add the Cinnamon Apples
Spoon the cooked cinnamon apples evenly over the bread layer, spreading them across the dish.

Step 8: Add the Remaining Bread
Layer the remaining soaked bread over the apples and gently spread it out without pressing it down too firmly.

Step 9: Make the Topping
Combine brown sugar and cinnamon in a small bowl. Cut in the cold butter until coarse crumbs form, then stir in chopped pecans or walnuts if desired.

Step 10: Add the Topping
Sprinkle the cinnamon-brown sugar mixture evenly over the top of the casserole.

Step 11: Bake
Cover loosely with foil and bake for 30 minutes. Remove the foil and bake for another 20–25 minutes, until golden and the center is set with a slight softness.

Step 12: Let It Rest
Remove from the oven and let the casserole rest for 10–15 minutes. This allows the custard to finish setting and makes serving easier.

Step 13: Garnish and Serve
Dust with powdered sugar if desired and serve warm with maple syrup, caramel sauce, whipped cream, or your favorite breakfast topping.

Tips and Variations

Helpful Tips

• Use day-old or slightly stale bread for the best texture.

• Avoid completely cooking the apples before baking.
• Let the bread absorb the custard before assembling the casserole.
• Don’t pack the bread too tightly into the baking dish.
• Cover the casserole during the first part of baking to prevent excessive browning.

Watch Out for These Mistakes While Cooking

• Don’t use extremely fresh, soft bread without drying it first.
• Avoid adding too much custard, which can make the casserole soggy.
• Don’t overcook the apples before they go into the oven.
• Avoid using very watery apples without accounting for the extra moisture.
• Don’t skip resting the casserole after baking.
• Avoid baking at too high a temperature because the top can brown before the center sets.
• Don’t cut the casserole immediately after removing it from the oven.
• Avoid pressing the bread down too tightly.
• Don’t add too much sugar if you’re planning to serve it with plenty of syrup.
• Check the center before removing the casserole from the oven to ensure the custard has set.
