Tips & Variations

- Feel free to substitute berries with sliced apples or peaches for a seasonal twist.
- For extra flavor, add a teaspoon of vanilla extract to the egg mixture.
- To make it dairy-free, swap whole milk with a plant-based milk and use a dairy-free butter alternative.

FAQs
Can I use a different type of bread?
Yes, brioche, challah, or even sturdy sandwich bread can be used. Just make sure the bread is slightly stale to better soak up the custard.
Can I prepare this recipe without chilling overnight?
While chilling overnight produces the best texture, you can let it sit for at least 3 hours if short on time. This allows the bread to absorb the custard thoroughly.

Additional
- 1 cup berries (frozen is fine)
Instructions
- Prepare the casserole dish: Butter or grease a 9×13-inch casserole dish thoroughly to prevent sticking.

- Soak the bread: Pour the egg mixture evenly over the bread cubes, making sure each piece is well coated and saturated with the custard.
- Chill overnight: Cover the dish with aluminum foil and refrigerate for at least 3 hours, preferably overnight, to allow the bread to absorb the custard fully.

Notes
- Day-old bread is highly recommended as it better absorbs the custard mixture without becoming mushy.
- You can substitute whole milk with 2% or any milk alternative, but the texture and richness may change.
- Fresh or frozen berries both work well; if using frozen, no need to thaw beforehand.
- For extra flavor, consider adding a splash of vanilla extract or a pinch of nutmeg to the custard mixture.
- Leftovers can be refrigerated for up to 3 days and reheated gently.
