Ingredients

This recipe uses simple, easy-to-find ingredients that work together to create layers of flavor and texture. Each ingredient plays an important role in the final result.

Main Ingredients

• 1 lb sourdough or French bread, cut into chunks
  Slightly firm bread works best for French toast casseroles. Sourdough or French bread absorbs the custard well without becoming mushy.
• 8 large eggs
  Eggs are the foundation of the custard, providing structure, richness, and protein.
• 2 cups milk (whole or 2%)
  Milk adds moisture and creaminess to the custard mixture.
• 1/2 cup heavy whipping cream
  The cream enhances the richness and creates a soft, luxurious texture.
• 1/2 cup sugar
  Adds sweetness to the custard and balances the natural tang of the bread.
• 1/4 cup light brown sugar
  Brown sugar brings a subtle caramel-like depth to the flavor.
• 6–7 medium ripe bananas, chopped
  Ripe bananas provide natural sweetness, moisture, and a distinctive banana flavor.

Streusel Topping Ingredients

• 3/4 cup all-purpose flour
  Forms the base of the streusel topping.
• 3/4 cup firmly packed brown sugar
  Adds sweetness and helps create a crisp, caramelized topping.
• 1/2 cup salted butter
  Binds the streusel ingredients together and adds rich, buttery flavor.

Preparation Method

This recipe is designed to be simple and stress-free. Preparing it the night before allows the flavors to meld and ensures a perfectly baked casserole in the morning.

Step 1: Prepare the Baking Dish

Begin by greasing a 9×13-inch casserole dish thoroughly. This step prevents sticking and makes serving easier once the casserole is baked.

Step 2: Assemble the Bread and Bananas

Place the bread chunks into a large mixing bowl. Add the chopped ripe bananas and gently toss them together to distribute the bananas evenly throughout the bread. Transfer this mixture into the prepared casserole dish, spreading it out evenly.

Step 3: Make the Custard Mixture

In a separate bowl, whisk together the eggs, milk, heavy whipping cream, sugar, and light brown sugar until fully combined and smooth. Whisking thoroughly ensures the eggs are well incorporated, which helps create a uniform custard.

Step 4: Combine and Soak

Pour the custard mixture evenly over the bread and banana mixture in the casserole dish. Use a spoon or spatula to gently press the bread down so that all pieces are coated and submerged. This step is essential for even soaking.

Step 5: Refrigerate Overnight

Cover the casserole dish tightly with plastic wrap or foil and place it in the refrigerator. Allow it to soak overnight, or for at least several hours. This resting time allows the bread to fully absorb the custard, resulting in a soft, cohesive texture.

Step 6: Preheat the Oven

The next morning, preheat your oven to 350°F (176°C). Remove the casserole from the refrigerator while the oven preheats to allow it to come closer to room temperature.

Step 7: Bake the Casserole

Place the casserole dish in the oven and bake for 35–40 minutes, or until the top is golden brown and the custard is set. The center should feel firm but still moist.

Step 8: Prepare the Streusel Topping

While the casserole is baking, prepare the streusel topping. In a bowl, combine the flour, brown sugar, and butter. Use your fingers or a fork to crumble the mixture until it resembles coarse crumbs.

Step 9: Add Streusel and Finish Baking

During the final five minutes of baking, remove the casserole from the oven and sprinkle the streusel topping evenly over the surface. Return the dish to the oven and bake until the topping is lightly browned and crisp.

Step 10: Serve

Remove the casserole from the oven and allow it to rest for a few minutes before serving. Serve warm, plain or with maple syrup or other desired toppings.

Why This Recipe Works

Storage and Reheating
