Ingredients
Scale
Casserole
- 1 lb loaf Sourdough or French Bread, cut into chunks
- 8 large eggs
- 2 cups (480ml) milk (whole or 2%)
- 1/2 cup (120ml) heavy whipping cream
- 1/2 cup (104g) sugar
- 1/4 cup (36g) light brown sugar, unpacked
- 2 tsp vanilla extract
- 1 1/2 tsp ground cinnamon
- 6–7 medium sized bananas, chopped*
Streusel Topping
- 3/4 cup (98g) all-purpose flour
- 3/4 cup (169g) firmly packed brown sugar
- 1 tsp cinnamon
- 1/2 cup (112g) salted butter, cut into pieces
Instructions
- Prepare the Casserole Dish: Grease a 9×13 inch casserole dish thoroughly to prevent sticking during baking.
- Add Bread Chunks: Place the cut sourdough or French bread chunks into a large mixing bowl and set aside.
- Make the Egg Mixture: In a separate large bowl, whisk together the eggs, milk, heavy cream, sugar, brown sugar, vanilla extract, and ground cinnamon until well combined and smooth.
- Combine Ingredients: Pour the egg mixture over the bread chunks, then add the chopped bananas. Gently stir everything together to ensure the bread pieces and bananas are fully soaked in the custard mixture.
- Refrigerate Overnight: Transfer the soaked bread mixture into the prepared casserole dish, spreading evenly. Cover the dish with plastic wrap or foil, then refrigerate overnight to allow the bread to absorb the custard fully.
- Preheat Oven: When ready to bake, preheat your oven to 350°F (176°C).
- Bake the Casserole: Bake the casserole uncovered for about 35-40 minutes, until it is set and slightly golden on top, or until it reaches your desired level of doneness.
- Prepare Streusel Topping: While the casserole is baking, mix together the flour, brown sugar, and cinnamon in a bowl. Add the salted butter pieces and use your fingers or a pastry cutter to mash the butter into the dry ingredients until you get a crumbly streusel mixture.
- Add Streusel and Finish Baking: When the casserole is nearly done baking, remove it from the oven. Sprinkle the streusel topping evenly over the surface, then return the casserole to the oven and bake for an additional 5 minutes until the topping is melted and slightly crispy.
- Serve: Remove from oven and allow to cool slightly. Serve warm with syrup for a delicious breakfast treat.
Notes
- * The bananas are sliced and then each slice is cut into quarters to distribute evenly throughout the casserole.
- You can use either whole or 2% milk depending on your preference.
- For a richer casserole, use heavy whipping cream as specified.
- Make sure to cover and refrigerate the casserole overnight to allow full custard absorption.
- Feel free to add a drizzle of maple syrup or fresh fruit when serving.
