How to Make Overnight Baked Banana French Toast Casserole

Let’s embark on a delightful culinary adventure together, making your Overnight Baked Banana French Toast Casserole. It’s a simple process, and I assure you, your kitchen will soon be filled with mouth-watering aromas!

Step 1: Prepare Casserole

First, grab a mixing bowl. Whisk together the eggs, milk, heavy cream, both sugars, vanilla extract, and ground cinnamon. This mixture is the heart of your casserole—a sweet, creamy embrace!

Next, add the bread chunks and the chopped bananas to the bowl. Gently toss everything together until the bread soaks up that rich custard goodness. I love watching the vibrant yellow bananas mix with the soft, doughy bread. It’s like a cozy hug for your breakfast dish.

Once combined, transfer the mixture into a greased baking dish. Make sure to spread it out evenly. This ensures every bite will be just as tasty as the last. Cover it tightly with plastic wrap or aluminum foil and let it chill in the refrigerator overnight. Trust me, good things come to those who wait!

Step 2: Make Streusel Topping

As you dream of the delicious casserole waiting for you, let’s make the streusel topping! In a separate bowl, combine the all-purpose flour, firmly packed brown sugar, and a sprinkle of cinnamon. Use a pastry cutter or your fingertips to mix in the cut-up salted butter. You want it to become crumbly—think sandy texture. This step is incredibly satisfying!

Here’s where you can unleash your creativity: consider adding chopped nuts like walnuts or pecans if you enjoy a crunchy contrast. Once your streusel is ready, sprinkle it generously over your casserole. Cover it again and return to the refrigerator, letting the flavors meld beautifully.

Step 3: Bake

When morning arrives, preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and let it sit at room temperature while the oven heats. This little step makes for even baking.

Bake the casserole for about 45-55 minutes, until it’s puffed up and golden brown. You’ll know it’s done when the edges are slightly crispy and the center is just firm enough. Oh, the aroma wafting through your home will be heavenly, drawing everyone to the kitchen like bees to honey!

Once baked to perfection, let it cool for a few moments before serving. Every slice will reveal layers of sweetness, bringing smiles and satisfaction all around the table.

Tips for Success

For the best texture in your Overnight Baked Banana French Toast Casserole, use day-old bread. It absorbs the custard beautifully without getting soggy.

Make sure to cover the casserole tightly to prevent any odors from infiltrating while it chills overnight.

If you want a little crunch, add nuts to the streusel topping. These simple tips will ensure your casserole is a crowd-pleaser every time!
