Caramelized Custardy French Toast

This overnight crème brûlée French toast transforms simple ingredients into a luxurious breakfast that feels like dessert for your morning meal. The magic happens while you sleep, as thick slices of French bread soak up a rich vanilla custard, ready to be baked to golden perfection and finished with a crackling caramelized sugar crust.

I first created this recipe for a Christmas morning breakfast, hoping to find something special I could prepare the night before. Now it's become our family tradition for every celebration morning when we want something indulgent without missing out on the festivities.

Ingredients

• French bread thick slices create the perfect base with their sturdy texture that holds up to overnight soaking
• Large eggs provide richness and structure to the custard mixture

• Granulated sugar sweetens the custard and creates that signature crackly topping

• Maple syrup for serving complements the caramelized sugar notes beautifully

Step-by-Step Instructions

Prepare the Baking Dish

Butter your baking dish thoroughly to prevent sticking. Arrange bread slices in a single overlapping layer to create a solid base that will soak up the custard evenly while maintaining some texture. Make sure every inch of your dish is covered with bread.

Create the Custard Mixture

Whisk eggs vigorously until completely broken down before adding half and half and milk gradually. This prevents lumps in your custard. Add vanilla, sugar and spices last, whisking until the mixture looks smooth and the sugar is mostly dissolved. The consistency should be like a rich, pourable cream.

Soak the Bread Thoroughly

Pour custard slowly over each slice of bread, ensuring complete coverage. Take time to spoon mixture over any dry spots. Press bread gently to help absorption without crushing the slices. The bread should be saturated but still maintaining its shape.

Overnight Magic

Cover tightly with plastic wrap pressed directly onto the surface to prevent a skin from forming. Refrigerate for at least 8 hours, though 12 is even better. This waiting period is crucial for the bread to fully absorb the custard and for the flavors to meld together completely.

Baking Process

Dot with butter pieces evenly across the surface before baking. The initial sugar sprinkle helps create a preliminary crust. Bake until the center feels set but still slightly jiggly, and the top is golden brown with slightly crisp edges. The French toast should puff up significantly.

Creating the Brûlée Effect

Sprinkle an even, thin layer of sugar across the entire surface. If using a kitchen torch, hold about 2 inches away and move continuously to prevent burning. If using a broiler, watch constantly as it can go from perfect to burnt in seconds. The sugar should melt and bubble before turning amber.

Serving Perfection

Let cool for 5 minutes to allow the caramelized sugar to harden and the custard to set. Cut into squares or serve by the slice. The contrast between the crackling top and soft interior is the hallmark of this dish.

My absolute favorite moment with this dish is the collective gasp it gets when I bring it to the table. The amber caramelized top catching the light makes it look far more complex than it actually is to prepare. I particularly love using challah bread when I can find it the texture creates an even richer result.

Make It Your Own

This recipe welcomes customization based on your preferences. Try adding a layer of cream cheese between the bread slices for a cheesecake inspired variation. A sprinkle of fresh berries just before serving adds bright acidity that balances the richness. For a holiday twist, add a tablespoon of orange zest to the custard mixture and serve with cranberry compote.

Storage and Reheating

While best enjoyed fresh, leftovers can be refrigerated for up to three days. The caramelized top will soften in the refrigerator, but the flavor remains delicious. Reheat individual portions in the oven at 325°F for about 10 minutes until warmed through. Avoid microwave reheating which makes the texture soggy. For best results, save the caramelization step until just before eating if you know you'll have leftovers.

A Touch of History

French toast itself dates back centuries, with early versions appearing in Roman cookbooks. The brûlée technique comes from classic French dessert tradition, where sugar is caramelized to create a contrasting texture. This recipe brilliantly marries these two culinary traditions into something uniquely satisfying that bridges breakfast and dessert. The overnight technique likely developed in response to busy households looking for convenient yet special breakfast options.

Perfecting the Brûlée

The caramelized sugar topping is what elevates this from regular French toast to something extraordinary. For best results, use regular granulated sugar rather than brown sugar for the topping. Sprinkle it evenly but not too thick about 2 tablespoons total across the entire dish. Work in sections when caramelizing, allowing each area to cool slightly before moving to the next. Listen for the subtle crackling sound as the sugar hardens this signals success.

Common Questions

→ Can I prepare this dish the same day instead of overnight?

Yes, though the overnight soak produces the best texture. For same-day preparation, allow the bread to soak in the custard mixture for at least 2-3 hours before baking to ensure proper absorption.

→ What's the best bread to use for this French toast?

A sturdy French bread or brioche works best as they hold up well to the custard soaking without falling apart. Day-old bread is ideal as it absorbs more of the custard mixture.

→ Can I make this dish dairy-free?

Yes, substitute the dairy ingredients with plant-based alternatives like almond milk, coconut cream, and vegan butter. The caramelization process will still work with granulated sugar.

→ How do I caramelize the sugar if I don't have a kitchen torch?

You can use your oven's broiler setting. Place the dish on the top rack, about 4-5 inches from the heat source, and broil for 2-3 minutes while watching carefully to prevent burning.

→ Can I freeze leftovers of this French toast?

Yes, once cooled, portion the leftovers and freeze in airtight containers for up to 1 month. Reheat covered in a 350°F oven until warmed through, then add fresh caramelized sugar if desired.

→ What can I serve alongside this French toast?

Fresh berries, sliced bananas, whipped cream, or a side of bacon or sausage complement this dish perfectly. A light fruit salad provides a refreshing contrast to the richness.
