How to Make French Toast Casserole
-
Prepare Bread: Grease a 9×13-inch baking dish with unsalted butter or coconut oil. Layer the cubed, slightly stale challah bread evenly in the dish to create a sturdy base.
-
Make Custard: In a large mixing bowl, whisk together the eggs, milk, brown sugar, vanilla extract, cinnamon, nutmeg, and sea salt until well combined. This mixture will create that delicious custardy texture.
-
Combine: Pour the custard evenly over the layers of bread, ensuring every piece is moistened. Let it soak for a moment, so the bread absorbs the flavors thoroughly.
-
Chill (Optional): If you prefer to prep ahead, cover the dish and refrigerate overnight to enhance the flavors. If baking immediately, let it sit at room temperature for about 30 minutes.
-
Bake: Preheat your oven to 350°F. Drizzle melted butter over the casserole and sprinkle with brown sugar and pecans, if desired. Bake covered for about 35 minutes, then uncover and bake for an additional 10-20 minutes until the top is golden brown and crispy.

Rest & Serve: Once baked, let the casserole rest for 10 minutes before serving. Slice into portions and drizzle with maple syrup for that classic French toast experience.
Optional: Garnish with fresh berries or a dusting of powdered sugar for an added touch of sweetness.

Expert Tips for French Toast Casserole
• Stale Bread: Use bread that’s 1-2 days old to prevent sogginess. Fresh bread absorbs too much custard, making it dense.
• Even Soaking: Ensure every piece of bread is thoroughly moistened for a uniform texture. It helps achieve that custardy perfection throughout.
• Topping Timing: Add the crunchy topping just before baking. This keeps your French Toast Casserole crispy rather than soggy after resting.
• Monitor Baking: Ovens can vary in temperature; keep an eye on the casserole to prevent burning. Adjust the baking time accordingly, if needed.
• Customization Options: Feel free to mix in fruits or nuts like berries or walnuts before baking, enhancing both flavor and presentation.
