Ingredients

• 1 loaf of day-old French bread or brioche, cut into 1-inch cubes

• 3 large ripe bananas, sliced

• 1 cup chopped walnuts, toasted

• 6 large eggs

• 2 cups whole milk

• 1/2 cup heavy cream

• 1/2 cup granulated sugar

• 1/4 cup brown sugar, packed

• 2 teaspoons vanilla extract

• 1 teaspoon ground cinnamon

• 1/4 teaspoon ground nutmeg

• 1/4 teaspoon salt

• 2 tablespoons unsalted butter, melted

• Optional: powdered sugar or maple syrup for serving

Directions

1. Prepare the Baking Dish: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray to ensure the casserole doesn’t stick.

2. Toast the Walnuts: Spread the chopped walnuts on a baking sheet and toast them in the preheated oven for 5–7 minutes until fragrant. Set aside to cool.

3. Arrange the Bread: Place the cubed bread in the prepared baking dish. Ensure the cubes are evenly distributed.

4. Add the Bananas and Walnuts: Layer the sliced bananas over the bread cubes, then sprinkle the toasted walnuts evenly on top.

5. Mix the Custard: In a large bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, brown sugar, vanilla extract, cinnamon, nutmeg, and salt until fully combined and smooth.

6. Pour the Custard: Carefully pour the custard mixture over the bread, bananas, and walnuts. Press the bread gently down with a spatula to ensure it absorbs the custard evenly.

7. Drizzle Butter: Drizzle the melted butter over the top of the casserole to create a rich, golden crust.

8. Bake: Cover the casserole with aluminum foil and bake for 30 minutes. Remove the foil and bake for an additional 25–30 minutes until the top is golden brown and the custard is set.

9. Cool Slightly: Allow the casserole to cool for 10 minutes before serving. This helps it set and makes slicing easier.

10. Serve: Optionally, dust with powdered sugar or drizzle with maple syrup for extra sweetness. Serve warm and enjoy!

Tips & Notes

• Day-old bread works best: Using slightly stale bread ensures it absorbs the custard without becoming mushy. Brioche or challah adds extra richness.

• Make-ahead option: Assemble the casserole the night before, cover it, and refrigerate overnight. Bake in the morning for a stress-free breakfast.

• Nut alternatives: If you prefer, substitute walnuts with pecans or almonds for a different flavor profile.

• Sweetness adjustment: Depending on the ripeness of your bananas, you may want to reduce or increase the sugar slightly.

• Storage: Leftovers can be covered and stored in the refrigerator for up to 3 days. Reheat slices in the microwave or oven for best results.

Why This Recipe Works

The secret to the perfect Banana Walnut Crunch French Toast Casserole lies in the balance of textures and flavors. The bread provides a soft, airy base while the bananas add natural sweetness and moisture. Toasted walnuts bring a crunchy contrast that keeps each bite interesting. The custard, enriched with cream and eggs, seeps into every crevice of the bread, creating a creamy, melt-in-your-mouth consistency. This combination makes the dish indulgent enough for a special occasion but simple enough to enjoy on a lazy Sunday morning.

Serving Suggestions

This casserole pairs beautifully with fresh fruit, a dollop of Greek yogurt, or a drizzle of pure maple syrup. For a decadent brunch spread, serve alongside scrambled eggs, bacon alternatives, or a fresh fruit salad. It’s also a crowd-pleaser for holiday breakfasts, Mother’s Day brunches, or celebratory family gatherings, where you want a dish that’s both impressive and comforting.

The Inspiration Behind the Recipe

The idea for this recipe came from cherished weekend family breakfasts, where French toast was always the centerpiece. Bananas were often overlooked as a simple snack, but when baked into a custardy bread dish, they transform into a sweet, caramelized delight. Toasted walnuts add an element of surprise—providing texture, flavor, and a hint of nuttiness that elevates the dish. Over the years, this combination has become a staple in brunch menus and a favorite for those who love breakfast with a twist.

Variations to Try

1. Chocolate Banana Walnut: Add mini chocolate chips on top before baking for a sweeter treat.

2. Caramel Drizzle: Swirl caramel sauce over the casserole before baking for a rich, dessert-like flavor.

3. Tropical Twist: Substitute some bananas with sliced mango or pineapple for a tropical touch.

4. Spiced Version: Add a pinch of cardamom or ginger to the custard for a warm, aromatic flavor profile.

5. Gluten-Free Option: Use gluten-free bread to make this casserole suitable for those with dietary restrictions.

Healthier Alternatives

While this casserole is a comforting indulgence, you can make some small tweaks for a lighter version without compromising flavor:

• Use almond milk or oat milk instead of whole milk.

• Reduce the sugar slightly or use natural sweeteners like honey or maple syrup.

• Substitute a portion of the bread with whole-grain bread for added fiber.

• Lightly toast the walnuts instead of using buttered toppings to reduce fat content.

Tips for Perfect Custard

• Make sure your eggs are at room temperature; this helps create a smoother custard.

• Whisk the custard thoroughly to avoid clumps and ensure even distribution over the bread.

• Pressing the bread down gently into the custard ensures every cube absorbs the liquid, giving a consistent texture throughout.

Frequently Asked Questions

1. Can I make this Banana Walnut Crunch French Toast Casserole ahead of time?

Absolutely! One of the best things about this casserole is that it can be prepared the night before. Simply assemble the bread, bananas, walnuts, and custard in your baking dish, cover it tightly with plastic wrap or foil, and refrigerate overnight. In the morning, remove it from the fridge, let it sit at room temperature for a few minutes, then bake as directed. This make-ahead approach allows the bread to fully soak in the custard, giving you a richer, more flavorful casserole while saving time on busy mornings or holiday brunches.

2. Can I use other types of bread instead of French bread or brioche?

Yes! While day-old French bread or brioche works best due to its texture and ability to absorb custard, you can experiment with other breads. Challah, sandwich bread, or even whole-grain bread can be used. Just ensure the bread is slightly stale or dry; fresh bread may become too soggy when baked. Cubing the bread evenly and pressing it lightly into the custard will help all types of bread soak up the mixture properly.

3. How do I store and reheat leftovers?

Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, place individual servings on a microwave-safe plate and warm for 30–60 seconds, or reheat in the oven at 325°F (160°C) for 10–15 minutes until heated through. For the best texture, covering the casserole loosely with foil while reheating helps prevent it from drying out. Leftovers can also be enjoyed cold, straight from the fridge, though baking enhances the warm custardy texture.

4. Can I customize the recipe with different fruits or nuts?

Definitely! While bananas and walnuts are the classic choice, this casserole is highly versatile. You can swap bananas for berries, sliced apples, or pears, depending on your preference or the season. For nuts, pecans, almonds, or even pistachios work beautifully. Adding a few chocolate chips or a sprinkle of coconut flakes can also create a fun variation. The key is to maintain a balance between sweet, soft fruit and crunchy nuts to preserve the delicious texture contrast that makes this casserole so irresistible.
