How to Make French Toast Bake Casserole with Strawberries and Cinnamon Crumb Topping Recipe

Step 1: Prepare the Bread Base

Start by greasing a 9×13 inch baking dish to ensure nothing sticks. Cut your sourdough or baguette into 1-inch cubes and spread them evenly in the pan. This bread base is going to soak up all the delicious custard, so distributing the cubes evenly is key for consistent texture.

Step 2: Whip Up the Custard Mixture

In a large bowl, combine the eggs, milk, heavy cream, both sugars, vanilla extract, orange zest, cinnamon, and nutmeg. This mixture is the heart of your French Toast Bake, providing richness and spice. Pour it evenly over the bread cubes, giving everything a gentle push to soak in the goodness.

Step 3: Let It Chill Overnight

Cover your dish tightly with plastic wrap and refrigerate overnight. This resting period is crucial—it allows those bread cubes to completely absorb the custard, transforming into a soft, flavorful pudding-like texture once baked.

Step 4: Make the Cinnamon Crumb Topping

While your casserole chills, prepare the crumb topping. Mix together the flour, brown sugar, cinnamon, nutmeg, and salt. Add cold, cubed butter and use a fork to cut it into the dry ingredients until crumbly. Store this in a bag in the fridge overnight as well, so it stays cool and ready to crumble perfectly on top before baking.

Step 5: Bake to Perfection

When morning arrives, preheat your oven to 350 degrees Fahrenheit. Sprinkle the chilled crumb topping generously over the soaked bread, then bake for 45 minutes to an hour. Baking time can vary depending on your texture preference—less time yields a moister bake, longer results in a firmer pudding. The top should be golden and crisp, while the inside remains tender and custardy.

Step 6: Finish with Glaze and Strawberries

Once out of the oven, whisk together powdered sugar and milk into a smooth glaze and drizzle it decoratively over the warm casserole. Garnish with fresh strawberries to add vibrant color and bright, tangy notes that balance the sweet richness beautifully.

Garnishes

Fresh strawberries are classic, but feel free to add a sprinkle of toasted nuts like pecans or walnuts for crunch, or a dusting of cinnamon powder to amplify the cozy spice notes. A dollop of freshly whipped cream or a scoop of vanilla ice cream can make this dish feel extra indulgent.

Side Dishes

This casserole pairs wonderfully with light sides such as crisp bacon or sausage links to provide savory contrast. Fresh fruit salad or roasted citrus segments can also complement the rich, sweet notes of the bake without overpowering it.

Creative Ways to Present

For a festive brunch, serve the casserole in individual ramekins topped with a single strawberry and a mint leaf. Alternatively, a rustic wooden platter with small bowls of glaze, berries, and nuts allows guests to customize their portions, making the meal interactive and fun.

Make Ahead and Storage

Storing Leftovers

Cover any leftover French Toast Bake Casserole tightly with plastic wrap or in an airtight container and store it in the refrigerator for up to 3 days. The flavors actually develop even more after resting, making reheated slices just as delicious.

Freezing

You can freeze the casserole either before or after baking. Wrap individual portions or the entire dish securely in foil and plastic wrap to prevent freezer burn. Freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

Reheat leftovers in a 350 degree Fahrenheit oven until warmed through, about 15-20 minutes for slices and 30-40 minutes for a whole casserole. Cover with foil to prevent the topping from over-browning. Microwaving is also an option for quick reheats but may result in softer topping.

FAQs

Can I use bread other than sourdough or French baguette?

Absolutely! Sturdy breads like challah, brioche, or even a rustic country loaf work well because they absorb the custard without disintegrating. Avoid super soft sandwich breads as they may become too mushy.

Do I have to refrigerate the casserole overnight?

Yes, the overnight rest allows the bread to soak up all the custard mixture, which is what gives this bake its signature texture. If short on time, let it soak for at least 4-6 hours, but overnight is best.

Can I make this recipe gluten-free?

You can! Use a sturdy gluten-free bread that mimics the texture of sourdough or baguette. Also, ensure your flour for the crumb topping is gluten-free or substitute with almond flour for a nutty twist.

Why is the crumb topping cold?

The cold butter helps create a crumbly texture that crisps up beautifully during baking, adding a delightful crunch to contrast the soft custardy bread underneath.

How do I store the crumb topping if not baking immediately?

If you’re not using it the same day, keep the crumb topping in a sealed container or Ziploc bag in the refrigerator for up to 3 days or freeze it for longer storage. It can be sprinkled frozen on top before baking.
