How to Make Overnight French Toast Casserole

Step 1: Prepare the Bread

Cut your chosen bread into thick cubes or slices. Spread the pieces evenly in a buttered baking dish to form your casserole’s base.

Step 2: Whisk the Custard

In a large bowl, combine eggs, milk (or cream), sugar, vanilla extract, cinnamon, and any additional spices. Whisk thoroughly until well mixed.

Step 3: Assemble the Casserole

Pour the custard mixture evenly over the bread, pressing down gently to make sure each piece soaks up the mixture. Cover the dish tightly with plastic wrap or foil.

Step 4: Refrigerate Overnight

Place the assembled casserole in the refrigerator to soak for at least 8 hours, allowing the bread to absorb the custard fully.

Step 5: Bake to Golden Perfection

Preheat your oven to 350°F (175°C). Remove the casserole from the fridge, dot the top with small pieces of butter, and bake uncovered for 45-50 minutes until the top is puffed and golden brown.

Pro Tips for Making Overnight French Toast Casserole

• Use Stale Bread: Slightly stale bread absorbs custard better without falling apart during baking.
• Press Gently: Push down the bread in the custard to help it soak but avoid over-mixing to maintain texture.
• Cover Tightly: Ensure the casserole is well-covered in the fridge to avoid dryness or odor absorption.
• Butter the Dish: Prevent sticking and encourage a crisp, golden edge with a well-buttered pan.
• Try Soaking Time: Don’t rush the soak—overnight is best, but at minimum 4 hours will still give good results.

How to Serve Overnight French Toast Casserole

Garnishes

Add a dusting of powdered sugar, a drizzle of maple syrup, fresh berries, or a dollop of whipped cream for that extra wow factor. Toasted nuts also bring a lovely crunch on top.

Side Dishes

Serve your casserole alongside crispy bacon, fresh fruit salad, or a light green salad to balance the richness. Yogurt or cottage cheese pairs well too for a creamy contrast.

Creative Ways to Present

Cut the casserole into individual squares and serve on colorful plates for a lively breakfast table. Add small ramekins of toppings like jams or Nutella to encourage customization at the table.

Make Ahead and Storage

Storing Leftovers

Keep any leftover casserole covered in the refrigerator and consume within 3-4 days. Store it in an airtight container or tightly wrapped with plastic wrap.

Freezing

You can freeze the leftover casserole in portions. Wrap tightly in aluminum foil or use freezer-safe containers to preserve freshness for up to 2 months.

Reheating

Reheat refrigerated or frozen portions in the oven at 325°F (165°C) until warmed through, usually around 15-20 minutes. Microwaving works too for a quick single portion but may soften the crust.

FAQs

Yes, thicker breads like brioche, challah, or French bread work best for soaking up the custard, but feel free to experiment with what you have on hand.
