Step-by-Step Instructions

Making French toast casserole is straightforward and can be done in just a few steps. Follow these detailed instructions for a perfect dish:

  1. Preheat your oven to 350°F (175°C). This ensures that your casserole will bake evenly.
  2. Grease a 9×13-inch baking dish. This prevents sticking and makes clean-up easier.
  3. Place 10 cups of cubed bread (preferably brioche or challah) into the greased dish. This bread will absorb the custard nicely.
  4. In a large bowl, whisk together 8 eggs, 2 cups of milk, 1 cup of packed brown sugar, 1 tablespoon of vanilla extract, 2 teaspoons each of cinnamon and nutmeg, and 1/2 teaspoon of salt. This mixture creates a rich custard.
  5. Pour the custard evenly over the bread cubes. If you want to prepare it ahead, cover and refrigerate overnight. Otherwise, let it stand for 30 minutes at room temperature to soak.
  6. Add the topping: Drizzle the casserole with 1/2 cup of melted butter and sprinkle with 1/2 cup of brown sugar and 1 cup of chopped pecans.
  7. Bake covered for 35 minutes, then uncover and bake for an additional 10-20 minutes until the top is golden and the custard has mostly set.
  8. Let it stand for 10 minutes before serving. This helps the flavors meld together beautifully.
  9. Serve warm with maple syrup for drizzling.

Variations & Substitutes

French toast casserole can easily be customized. Here are some popular variations and substitutions:

  • For a healthier version, use whole grain bread instead of white or enriched bread.
  • Substitute almond milk or a milk alternative for a dairy-free option.
  • Add fruits like blueberries or sliced strawberries for a fresh twist.
  • Replace pecans with walnuts or omit nuts entirely for a nut-free dish.

Mistakes to Avoid

  • Not using stale bread: Fresh bread can become mushy. Use slightly stale bread for the best texture.
  • Skipping the soaking time: Allowing the bread to soak is crucial for flavor and texture.
  • Overmixing the custard: Whisk until just combined to avoid tough texture.
  • Not letting it rest before serving: This resting time allows flavors to settle and improves serving quality.
  • Neglecting to grease the dish properly: This can lead to sticking and difficulty in serving.

Storage & Reuse

To store leftovers, allow the casserole to cool completely, then cover it tightly with plastic wrap or aluminum foil. It can be refrigerated for up to 3 days. To reheat, place back in the oven at 350°F (175°C) until warmed through. You can also freeze slices wrapped in plastic wrap for up to a month, allowing for quick and easy breakfasts.

Conclusion

French toast casserole not only offers an easy, tasty solution for breakfast but also allows for plenty of creativity with flavors and ingredients. The best part? It can be prepared in advance and serves many, making it perfect for gatherings. So, grab your ingredients and delight your loved ones with this comforting dish!
