FAQs
Can I use frozen blueberries instead of fresh?
Yes, frozen blueberries can be used. There's no need to thaw them before adding to the casserole.
Can I prepare this casserole without refrigeration?
Refrigerating overnight allows the bread to absorb the custard fully, resulting in a softer texture. If you skip this step, the casserole may be firmer.
Can I use a different type of bread?
Yes, challah, brioche, or sourdough bread are excellent alternatives. Ensure the bread is slightly stale for optimal absorption of the custard.
Is it necessary to cover the casserole while baking?
Covering the casserole during the initial baking period helps it cook evenly. Uncovering it towards the end allows the top to brown.
Can I make this recipe gluten-free?
Yes, substitute the bread with a gluten-free variety to make the casserole gluten-free.
How can I make this recipe dairy-free?
Use dairy-free cream cheese and milk alternatives to accommodate a dairy-free diet.
Can I add a streusel topping?
Yes, a streusel topping made from butter, brown sugar, and flour can be added before baking for extra sweetness and crunch.
How do I prevent the casserole from being soggy?
Using slightly stale bread helps prevent sogginess, as it absorbs the custard without becoming too mushy.
Can I freeze the casserole before baking?
Yes, assemble the casserole, cover it tightly, and freeze for up to 2 months. Thaw overnight in the refrigerator before baking as directed.
Can I make individual servings instead of a large casserole?
Yes, divide the bread and custard mixture into individual ramekins and bake until set, adjusting the baking time as needed.
