How to Make ”’json

Preparation of the Dish

Start your culinary adventure by greasing a 9×13 inch casserole dish to ensure the casserole doesn’t stick. This step is essential for a flawless presentation. In a large mixing bowl, combine the chunks of sourdough or French bread with the chopped ripe bananas. This combination will be the foundation of your casserole, with the bread soaking up all the delicious custard mixture as it bakes.

Creating the Custard Mixture

In another bowl, whisk together the eight large eggs, two cups of milk, half a cup of heavy whipping cream, half a cup of sugar, and a quarter cup of light brown sugar. The mixture should be smooth and well-combined, with the sugars fully dissolved. This custard is what gives the dish its rich texture and flavor. For added depth, don’t forget to sprinkle in some vanilla extract and ground cinnamon, which will enhance the overall taste profile of the casserole.

Soaking the Bread

Once your custard is ready, pour it generously over the bread and banana mixture. With a gentle touch, stir everything together to ensure that every piece of bread is coated in the creamy custard. This step is crucial as it allows the bread to absorb the flavors overnight. After mixing, transfer the mixture into the prepared casserole dish. Cover it tightly with plastic wrap and refrigerate overnight. This allows the bread to soak up the custard mixture, resulting in a soft, flavorful casserole in the morning.

Baking to Perfection

When you’re ready to bake, preheat your oven to 350°F (176°C). Remove the casserole from the fridge and let it sit for a few minutes at room temperature. This will help it bake evenly. Place the dish in the preheated oven and bake for 35-40 minutes until the top is golden brown and the edges are bubbling. The aroma that fills your kitchen will be nothing short of divine, enticing everyone to gather around.

Adding the Streusel Topping

For the crowning touch, prepare the streusel topping by combining the flour, brown sugar, and melted butter in a bowl. Use your fingers to crumble the mixture until it resembles coarse crumbs. During the last five minutes of baking, sprinkle this delightful streusel over the casserole. This will add a crunchy texture that beautifully contrasts the soft custard.

Serving Your Casserole

Once baked, remove the casserole from the oven and let it cool slightly before serving. This dish is best enjoyed warm, and you can serve it with a drizzle of maple syrup or any toppings of your choice. Fresh fruit, whipped cream, or even a sprinkle of powdered sugar can elevate this dish even further, making it a stunning centerpiece for your breakfast or brunch table.

Tips for Success

  • Use day-old bread for better absorption of the custard mixture, as it will soak in flavors more effectively.
  • Feel free to customize by adding nuts, such as walnuts or pecans, for an extra crunch and flavor boost.
  • Chocolate chips can be a delightful addition for those with a sweet tooth, creating a dessert-like experience.
  • This casserole can be stored in the fridge for up to three days or frozen for two months, making it perfect for meal prep.
  • Letting the casserole sit for a few minutes after baking allows it to set, making it easier to serve.

Variations to Try

  • Add a layer of caramel sauce between the bread and bananas for an indulgent twist with a rich flavor.
  • Incorporate different fruits, such as strawberries or blueberries, to diversify the flavors and colors.
  • Substitute the sourdough with brioche for a richer, sweeter base that complements the bananas beautifully.
  • Try using almond milk or coconut milk in place of regular milk for a lactose-free version.
  • Incorporate spices like nutmeg or cardamom for a unique twist on the traditional cinnamon flavor.
