FAQs
1. Can I use frozen blueberries instead of fresh?
Yes! You can use frozen blueberries straight from the freezer. No need to thaw, just toss them in to avoid excess moisture.
2. Can I make this blueberry casserole without overnight chilling?
You can, but the texture improves with time. Chilling overnight gives the bread time to absorb the custard for a richer, creamier result.
3. How do I prevent the casserole from getting soggy?
Use slightly stale bread and avoid overmixing the custard. Also, bake uncovered for the last 10 minutes to crisp the top.
4. Can I make it dairy-free?
Absolutely. Substitute almond milk or oat milk and use dairy-free butter. The flavor stays wonderful and the texture remains luscious.
