Instructions

1. Crack 8 large eggs into a spacious mixing bowl. Whisk them thoroughly with 2 cups milk, ½ cup heavy whipping cream, ½ cup white sugar, ¼ cup brown sugar, 2 teaspoons vanilla extract, and 1 ½ teaspoons ground cinnamon until completely smooth.
2. Add 1 pound of sourdough or French bread chunks and 6-7 chopped medium bananas to the egg mixture. Gently fold everything together, ensuring each bread piece gets evenly coated.
3. Transfer the saturated bread mixture into a generously greased 9×13 inch baking dish, spreading it evenly across the surface.
4. Create the streusel by combining ¾ cup flour, ¾ cup firmly packed brown sugar, and 1 teaspoon cinnamon in a separate bowl. Cut ½ cup cold salted butter into small pieces and work it into the dry ingredients until the mixture resembles coarse crumbs.
5. Sprinkle the streusel topping uniformly over the bread and banana mixture, covering the entire surface.
6. Cover the baking dish with plastic wrap and refrigerate overnight to allow flavors to meld and bread to absorb the liquid.
7. Remove the casserole from the refrigerator 30 minutes before baking to reduce temperature shock.
8. Preheat your oven to 350°F. Bake the casserole uncovered for 45-55 minutes until the center is set and the top turns golden brown with crispy edges.

Notes

• Use day-old bread for the best texture and absorption of the custard mixture.
• Slice bananas thick so they hold their shape during baking and don’t turn mushy.
• If your bread is fresh, lightly toast it first to help it soak up the egg mixture more effectively.
• For a gluten-free version, swap regular bread with gluten-free bread and use a cup-for-cup gluten-free flour in the streusel topping.
