Recipe FAQ

Can I use fresh bread instead of day-old?

Day-old bread works best as it absorbs the custard without becoming too soggy, but slightly stale fresh bread can also be used.

How long should the casserole soak before baking?

Refrigerating for at least 30 minutes helps the custard fully soak into the bread; overnight soaking yields the best texture.

What bread types are ideal for this dish?

Rich breads like brioche or challah provide a tender crumb and absorb custard nicely, enhancing flavor and texture.

Can I add nuts to the topping?

Yes, adding pecans or walnuts gives a pleasant crunch and nutty contrast to the soft custard and sweet topping.

Are dairy-free alternatives suitable?

Using plant-based milk and cream alternatives works well, though it may slightly alter taste and texture.
