Instructions

1. Make the Streusel Topping:
   In a medium bowl, combine flour, brown sugar, cinnamon, and salt. Cut in the cold butter using a fork, pastry cutter, or your fingers until the mixture becomes crumbly and resembles coarse sand. Cover and refrigerate while you prepare the casserole.
2. Prepare the Custard Mixture:
   In a large mixing bowl, whisk together eggs, milk, vanilla, cinnamon, salt, and sugar until smooth and fully combined.
3. Assemble the Casserole:
   Grease a 9×13-inch baking dish with butter or nonstick spray. Tear or cube the French bread into bite-sized pieces and place them evenly in the pan. Pour the egg mixture evenly over the bread, pressing down gently so each piece soaks up the custard.
4. Add the Berries:
   Scatter the diced strawberries and blueberries evenly over the top of the soaked bread.
5. Chill:
   Cover the dish tightly with plastic wrap or foil and refrigerate for at least 4 hours, or overnight, to allow the bread to fully absorb the custard.
6. Bake:
   When ready to bake, preheat the oven to 350°F (175°C). Remove the casserole from the refrigerator and uncover. Sprinkle the chilled streusel evenly over the top.
7. Cook Until Set:
   Bake for 45–55 minutes, or until the casserole is puffed, golden brown, and set in the center.
8. Cool and Serve:
   Let it rest for 10–15 minutes before serving. Dust with powdered sugar and drizzle with maple syrup. Top with extra fresh berries if desired.

Tips

• Use day-old bread: Slightly stale French bread absorbs the custard better without becoming mushy.
• Don’t skip chilling: Refrigerating the casserole allows the flavors to blend and the texture to set.
• Cut butter while cold: Cold butter makes the streusel crumbly and crisp.
• For a richer flavor, substitute half-and-half for milk.
• Check doneness: The center should be set but slightly soft — not liquidy.

Variations and Substitutions

• Different Breads: Try brioche, challah, or Texas toast for a softer, richer texture.
• Other Fruits: Swap berries for peaches, raspberries, apples, or even mixed frozen fruit.
• Dairy-Free: Use almond, oat, or coconut milk and vegan butter for a dairy-free version.
• Nutty Crunch: Add chopped pecans, walnuts, or almonds to the streusel.
• Citrus Twist: Add orange zest to the custard for a bright flavor boost.

FAQs

Can I make this ahead of time?
Yes! Assemble the casserole the night before, cover it tightly, and refrigerate overnight. In the morning, simply sprinkle on the streusel and bake.

Can I use frozen berries?
Absolutely. Thaw them slightly and drain any excess liquid before adding to prevent sogginess.

Why is my casserole soggy?
Too much liquid or not enough soaking time can cause sogginess. Make sure to let the casserole rest and use sturdy bread.

Can I freeze it?
Yes! Bake, cool completely, then wrap tightly and freeze for up to 2 months. Reheat in the oven before serving.
