Turning plain bread into something extraordinary happens with a French toast casserole. This breakfast treat features buttery bread chunks soaked in creamy custard, topped with a crunchy, sweet nut layer that makes every bite interesting. What's great is how easy it is – just put it together before bed, and you'll wake up to an amazing breakfast with your home filled with sweet cinnamon and vanilla smells.

Every holiday, my family can't wait for this casserole. As the smell spreads through the house, I love watching everyone's excitement when they take their first bite – it makes all the prep time worth it.

Key Ingredients Breakdown

  • Quality bread: Go for brioche, challah, or sourdough left out for 1-2 days so it's slightly stale and soaks up more custard
  • Local eggs: They form your smooth custard base. Try to find ones with rich, orange yolks for better flavor
  • Full-fat milk or cream: Gives amazing richness. You can use plant-based options, but regular dairy makes the creamiest results
  • Real vanilla: Adds wonderful flavor. Madagascar bourbon vanilla works best if you can find it
  • Newly ground spices: They make everything taste better. Keep whole nutmeg and cinnamon sticks and grind them just when needed

Crafting Your Breakfast Delight

Getting the Bread Ready:
Cut your bread into big chunks that will keep their shape while they soak up all that tasty custard mix.
Making the Custard:
Mix eggs and milk until they're completely blended, then add warm spices and vanilla to create the flavorful mixture that will soak into the bread overnight.
Putting It Together:
Arrange bread pieces evenly, making sure custard covers everything completely so it all bakes the same way.
Adding the Topping:
Sprinkle a mix of brown sugar and pecans on top, which will turn into a sweet, crunchy layer as it bakes.
Baking It Up:
Turn your overnight creation into a golden-brown treat, watching for that perfect moment when the top gets crispy but the middle stays soft and custardy.

My grandma always told me to use brioche that was a day old, saying it worked best with the custard. After making this dish countless times, I can tell you she was absolutely right.

Tasty Accompaniments

Make your breakfast extra special by adding fresh berry sauce, warm maple syrup, and homemade whipped cream on the side. For something savory to balance the sweetness, try serving crispy bacon strips or breakfast sausage links.

Fun Variations

Switch things up by adding some orange zest for a fresh twist, or try toasted almonds instead of pecans. If you can't have dairy, coconut milk works great and adds a light tropical flavor to the mix.

Storage Solutions

Any leftovers will stay good for up to three days if you keep them in a sealed container. When you want to eat some later, warm individual servings in the oven to get that crispy top back.

Ingredients

→ Main Ingredients

01 1 loaf of day-old challah bread (around 1½ lbs), cut into 1-inch pieces
02 5 eggs, large
03 1½ cups of milk
04 2 teaspoons of vanilla
05 2 tablespoons of brown sugar
06 1 teaspoon ground cinnamon
07 ¼ teaspoon of nutmeg
08 A small pinch of sea salt
09 Butter, or coconut oil, for greasing

→ Topping Mix

10 2 tablespoons of melted butter (or substitute coconut oil)
11 2 tablespoons brown sugar
12 ½ cup of pecan pieces, chopped

→ Optional Add-Ons

13 Maple syrup, as preferred

Instructions

Step 01

Butter up a 9x13-inch dish and spread the cubed bread across the bottom in an even layer.

Step 02

Mix eggs, milk, brown sugar, vanilla, cinnamon, nutmeg, and salt together in a big bowl until smooth. Pour the mix over the bread so it soaks in everywhere.

Step 03

Leave the dish untouched for 30 minutes at room temp to let the custard soak in. Or, better yet, cover it and chill it in the fridge overnight.

Step 04

Set the oven to 350°F so it heats up while you get the rest ready.

Step 05

Pour the melted butter over the bread, then sprinkle the brown sugar and pecans on top. Cover with foil and bake for about 35 minutes. Take off the foil and keep baking for another 10-20 minutes until golden on top and the custard is no longer jiggly.

Step 06

Give it a 10-minute break, covered lightly with foil. Serve warm with syrup on the side, if you like.
