How to Make Banana French Toast Casserole with Streusel Topping Recipe

Step 1: Prep the Bread and Bananas

Start by greasing a 9×13 baking dish with pan spray or butter to prevent sticking. Spread your well-dried bread cubes evenly across the bottom—this creates the perfect sponge for soaking up the custard. Then scatter the sliced bananas gently over the bread, ensuring each bite will have those lovely bursts of banana flavor.

Step 2: Whisk Together the Custard

In a large bowl, whisk the eggs, milk, heavy cream, brown sugar, vanilla bean paste, cinnamon, and salt until fully combined. Slow and steady is the way to go when pouring this heavenly custard over the bread and bananas—this helps keep everything in place and lets the bread begin soaking up the custard immediately.

Step 3: Let it Rest

Now comes the magic: tightly cover your dish with plastic wrap and pop it into the refrigerator for at least 2 hours, or even better, overnight. This soaking period lets every bread cube fully absorb the rich, flavorful custard, setting the stage for a creamy, custardy bake.

Step 4: Make the Streusel Topping

Combine the flour, brown sugar, cubed cold butter, cinnamon, and salt in a medium bowl. Use a pastry cutter or fork to mix until crumbly. You want large, buttery crumbs that will bake into a crisp, sweet topping—a brilliant textural contrast to the soft casserole.

Step 5: Top and Bake

Remove the dish from the fridge and distribute the crumble topping evenly by squeezing handfuls of it and breaking into rustic clumps over the entire surface. Preheat your oven to 350 degrees Fahrenheit, then bake for 40-45 minutes or until the custard is set and the streusel turns a beautiful golden brown. Let it cool a bit before serving. The aroma alone will have you drooling!

The bottom layer is a dense, golden brown bread base, topped with a soft layer of banana slices, then a crumbly, slightly darker brown streusel layer. On top, there is a drizzle of white cream sauce flowing down the sides, and more banana slices are arranged on the very top. Some powdered sugar is sprinkled over the top, adding a light dusting contrast. In the background, blurred white dishes and bowls add depth without distracting from the main dish.

Make Ahead and Storage

Storing Leftovers

Leftover Banana French Toast Casserole with Streusel Topping Recipe keeps beautifully in an airtight container in the refrigerator for up to 3 days. The flavors deepen, and it reheats wonderfully, making it a perfect make-ahead treat.

Freezing

If you want to store it longer, freeze leftovers in a freezer-safe dish or wrapped tightly in foil for up to 2 months. Thaw overnight in the fridge before reheating to preserve the texture and flavors.

Reheating

To warm up leftovers, bake in a preheated 350-degree oven for 15-20 minutes until heated through and slightly crisp on top again. You can also microwave individual servings, but the oven method keeps that glorious streusel crunchy.

FAQs

Can I use another type of bread for this casserole?

Absolutely! While brioche or a day-old baguette are best for their texture and ability to soak custard, you can use challah, Texas toast, or even sourdough for interesting flavor twists. Just avoid very soft or pre-sliced sandwich bread as it might get too mushy.

How ripe should the bananas be?

For the richest sweetness and best flavor, use bananas that are fully ripe with several brown spots. They’ll blend beautifully into the casserole, but not so mushy that they become unpleasant in texture.

Can I prepare this recipe a day in advance?

Yes! In fact, this Banana French Toast Casserole with Streusel Topping Recipe is best when prepped ahead. The overnight soak allows the bread to absorb all the delicious custard flavors and makes your brunch hassle-free.

Is there a substitute for heavy cream?

If you want to lighten things up, you can replace heavy cream with whole milk, but keep in mind the custard will be a bit less rich and creamy. Half-and-half also works nicely as a middle ground.

Can this recipe be made gluten-free?

For a gluten-free version, swap out the regular bread for a gluten-free loaf and use gluten-free all-purpose flour in the streusel. The results are slightly different in texture but still delicious and safe for gluten-sensitive folks.
