Ingredients

Why this recipe works

The magic of this bake lies in the contrast between the soft, custard-soaked bread and the crisp, caramelized sugar topping. Soaking the bread in a mixture of eggs, cream, and milk allows the custard to permeate every slice, creating a creamy, almost pudding-like interior as it bakes.

Meanwhile, the brown sugar and butter melt together on top, forming a golden crust that shatters with each bite, echoing the signature crack of creme brulee.

Baking the dish in a single layer ensures even cooking and a consistent texture throughout. The high ratio of cream to eggs yields a rich, silky custard that sets gently without becoming rubbery. As the bake rests after coming out of the oven, the custard continues to firm up, making it easier to slice and serve. This method delivers a restaurant-quality breakfast with minimal hands-on time.

Notes and substitutions

Choose a sturdy bread like French bread, brioche, or challah that can hold up to the custard without turning soggy. Day-old bread works best because it absorbs the custard more slowly and evenly.

For the custard, use whole milk and heavy cream for the richest flavor; you can substitute half-and-half for a lighter version, but the texture will be less indulgent. The vanilla extract adds warmth and depth, so don’t skip it.

This recipe calls for a 9x13-inch baking dish, which fits about 8 to 10 thick slices of bread. If you have a smaller dish, you can reduce the ingredients proportionally. The topping is simple: brown sugar and butter.

Use unsalted butter to control the salt level, and make sure the brown sugar is packed firmly for an even layer. You can also add a pinch of cinnamon or nutmeg to the custard if you like, but the classic version is pure vanilla.

• heavy cream: Half-and-half can replace the heavy cream for a lighter custard, but the texture will be less rich.
• French bread: Brioche or challah work beautifully and soak up the custard well.
• whole milk: 2% milk can be used, though the custard will be slightly less creamy.
• vanilla extract: 1 vanilla bean, split and scraped, can replace the extract for a more intense vanilla flavor.
