FAQs
Can I use any type of bread for this recipe?
Yes, but sturdier bread like brioche, challah, or French bread works best as they absorb the custard mixture without becoming too mushy.
Do I have to let it sit overnight?
While overnight soaking enhances the flavor and texture, you can refrigerate it for at least 4 hours if you’re short on time.
Can I prepare this without eggs?
Yes, you can substitute eggs with a mixture of mashed bananas, flaxseed meal, or a commercial egg replacer.
How do I prevent the casserole from being soggy?
Use slightly stale bread, ensure the correct custard-to-bread ratio, and avoid over-soaking the bread.
Can I make this recipe in a slow cooker?
Yes! Cook on low for 4-5 hours or until set.
What toppings go well with this casserole?
Maple syrup, powdered sugar, fresh fruit, nuts, whipped cream, or even caramel sauce are great options.
Can I make this casserole savory instead of sweet?
Yes! Skip the sugar and vanilla, and add cheese, cooked bacon, or sautéed vegetables for a savory version.
Is it necessary to grease the baking dish?
Yes, greasing the dish prevents sticking and makes for easier cleanup.
What’s the best way to serve this dish?
Serve warm with your favorite toppings and a side of coffee or fresh juice.
Can I use non-dairy milk?
Absolutely! Almond, oat, or coconut milk are great alternatives.
