Ingredients You’ll Need

This Blueberry French Toast Casserole Recipe calls for simple, everyday ingredients that combine to create layers of flavor and texture. Each component plays a key role, from the sturdy French bread that soaks up the custard to the fresh blueberries that provide bursts of tart sweetness, and the crumbly, buttery topping that adds irresistible crunch.

• French bread, 1 loaf (10 cups cubed): Use slightly stale bread for the best texture that absorbs the custard without getting soggy.
• Fresh or frozen blueberries, 1 ½ cups: These add natural sweetness and a juicy pop with every bite.
• Large eggs, 8: Eggs create the rich custard that holds everything together beautifully.
• Whole milk, 2 ¼ cups: Milk adds creaminess that soaks into the bread and keeps the casserole moist.
• Cinnamon, 1 teaspoon: Provides warmth and depth of flavor that complements the blueberries perfectly.
• Ground nutmeg, ½ teaspoon: Adds a subtle, spicy note for complexity.
• Brown sugar, ¾ cup packed: Sweetens the custard naturally and gives a hint of caramel flavor.
• Vanilla extract, 1 tablespoon: Brings a fragrant, inviting aroma that lifts the entire dish.
• Topping ingredients: Brown sugar (1/3 cup), all-purpose flour (1/3 cup), cinnamon (1 teaspoon), cold butter (6 tablespoons, cut into pieces), and chopped pecans (½ cup) make a crisp, nutty crumble that contrasts perfectly against the soft casserole.

How to Make Blueberry French Toast Casserole Recipe

Step 1: Prepare the Bread and Blueberries

Start by greasing a 9×13-inch baking dish with non-stick spray. Cut your French bread into 1-inch cubes, then layer them evenly in the dish. Scatter the blueberries over the bread cubes to ensure you get juicy pockets of fruit throughout the casserole.

Step 2: Make the Custard Mixture

In a medium bowl, whisk together the eggs, whole milk, cinnamon, ground nutmeg, brown sugar, and vanilla extract until perfectly combined. This custard is the heart of the casserole — it soaks into the bread and blueberries, imparting plenty of decadence and flavor.

Step 3: Combine and Refrigerate

Pour the custard mixture evenly over the bread and blueberries in the baking dish. Gently toss everything together so the bread cubes get fully coated but don’t break apart. Cover the dish with plastic wrap and refrigerate for at least 3 hours or overnight. This soak time allows the bread to soak up all the custard goodness, making the casserole buttery-soft inside.

Step 4: Prepare the Topping

Before baking, preheat your oven to 350 degrees Fahrenheit. In a small bowl, blend together the brown sugar, flour, and cinnamon. Cut the cold butter into small pieces and use a pastry cutter or fork to combine the mixture until crumbly. Stir in the chopped pecans for a delightful crunch.

Step 5: Bake Until Golden

Remove the casserole from the fridge and evenly sprinkle the crumbly topping all over the surface. Bake for 50 to 55 minutes, or until the top is beautifully golden brown and caramelized. The aroma filling your kitchen will be pure bliss!

Make Ahead and Storage

Storing Leftovers

Leftover Blueberry French Toast Casserole can be stored covered in the refrigerator for up to 3 days. Make sure it cools completely before refrigerating to preserve the textures and prevent sogginess.

Freezing

You can freeze unbaked casserole after assembling it and covering tightly with foil and plastic wrap. It will last up to 1 month in the freezer. When ready to bake, thaw in the fridge overnight before topping and cooking as usual.

Reheating

Reheat leftovers gently in the oven at 325 degrees Fahrenheit for 15-20 minutes until warmed through and the topping regains some crunch. Microwaving is possible but may soften the topping.

FAQs

Can I use frozen blueberries for this Blueberry French Toast Casserole Recipe?

Absolutely! Frozen blueberries work just as well as fresh ones. Just be sure to thaw and drain any excess liquid to avoid making the casserole too wet.

What type of bread is best for this recipe?

A sturdy loaf like French bread or a good challah works best because it holds up well during soaking, giving you soft yet defined cubes without turning mushy.

Can I make this Blueberry French Toast Casserole Recipe dairy-free?

Yes! Substitute the whole milk with almond, oat, or coconut milk, and use dairy-free butter for the topping — the casserole will still be delicious and rich.

How long can I soak the casserole before baking?

The casserole can be soaked anywhere from 3 hours up to overnight. The longer soaking time makes the bread softer and the overall custard more cohesive.

Is there a way to make this casserole more crunchy on top?

Adding extra chopped nuts to the topping or briefly broiling the casserole for the last 2-3 minutes of baking can increase the crunch factor while maintaining a tender inside.
