Ingredients for the Best Blueberry French Toast Casserole

Here’s everything you’ll need to make this dreamy breakfast casserole – I promise it’s all simple stuff you probably have already! Just make sure to measure carefully – baking is science, but delicious science.

• 1 loaf French bread (about 16 oz), cut into 1-inch cubes – slightly stale works best!
• 6 large eggs – room temperature blends smoother
• 2 cups whole milk – the fat makes it extra rich
• 1/2 cup heavy cream – trust me, this makes all the difference
• 1/2 cup granulated sugar – just enough sweetness
• 1 tbsp pure vanilla extract – the good stuff, not imitation
• 1 tsp ground cinnamon – warm spice perfection
• 2 cups fresh blueberries – rinsed and patted dry (frozen works too – don’t thaw!)
• 1/4 cup packed brown sugar – for that caramelized magic on top
• 1 tbsp melted unsalted butter – because butter makes everything better

See? Nothing fancy – just pantry staples transformed into something extraordinary!

Equipment You’ll Need

You’ll need just a few basics for this recipe: a 9×13-inch baking dish, a mixing bowl, and a whisk. If you want that extra crispy top, make sure your dish is broiler-safe. Simple tools for a seriously delicious breakfast!

How to Make the Best Blueberry French Toast Casserole

Okay, let’s get to the good stuff! This recipe comes together so easily – just follow these simple steps and you’ll have a gorgeous, golden casserole in no time. Pro tip: put on your favorite morning playlist while you work – it makes the process even more enjoyable!

1. Preheat your oven to 350°F (175°C) – this gives it time to reach the perfect temperature while you prep everything else.
2. Grease that 9×13-inch baking dish really well with butter or nonstick spray. Nobody wants their beautiful casserole to stick!
3. Spread your bread cubes evenly in the dish – don’t worry about perfection here, just make sure they’re in an even layer.
4. Whisk together eggs, milk, cream, sugar, vanilla, and cinnamon until completely smooth. I like to do this in a big measuring cup for easy pouring.
5. Pour the custard mixture over the bread and gently press down with a spatula to help the bread soak up all that deliciousness.
6. Scatter blueberries on top – I like to push some down into the bread too for surprise bursts of flavor.
7. Sprinkle with brown sugar and drizzle melted butter – this creates that irresistible crispy, caramelized top.
8. Bake for 45-50 minutes until golden brown and set in the center. Your kitchen will smell amazing!
9. Let it cool for 5 minutes before serving – I know it’s hard to wait, but this helps it set perfectly.

Pro Tip for the Perfect Texture

Want to avoid soggy bread? Use slightly stale bread and press down gently during soaking – this helps every cube absorb the custard evenly. The result? A perfectly balanced texture throughout!

Make-Ahead and Storage Tips

Here’s the best part – you can prep this casserole the night before! Just assemble everything (stop before the brown sugar topping), cover tightly, and refrigerate overnight. In the morning, add the brown sugar and butter, then bake as directed. Leftovers keep beautifully in the fridge for 2 days – just reheat at 350°F for about 15 minutes until warmed through. The blueberries stay juicy, and the bread gets even more custardy – if that’s possible!

Serving Suggestions for Best Blueberry French Toast Casserole

Oh, the fun part! This casserole shines all on its own, but a few extras take it over the top. My family goes wild when I dust it with powdered sugar “snow” or drizzle warm maple syrup over each serving. A dollop of fresh whipped cream never hurts either!

For a full brunch spread, pair it with crispy beef bacon or sausage links – that salty-sweet combo is magic. Fresh fruit salad balances the richness perfectly. And please, serve it straight from the baking dish with lots of coffee refills – that’s the true breakfast bliss!

Frequently Asked Questions

I get so many questions about this recipe – here are the ones that pop up most often from friends and family (and my own kitchen experiments!):

Can I use frozen blueberries?

Absolutely! Just toss them in frozen – no need to thaw. They’ll release just the right amount of juice as they bake. Sometimes I actually prefer frozen because they hold their shape better!

How do I prevent a dry casserole?

The secret is in the custard ratio – don’t skimp on the milk and eggs! Also, covering with foil for the first 30 minutes of baking helps keep moisture in. If your bread was super dry to start, you might need an extra splash of milk too.

Can I make this dairy-free?

You bet! Swap the milk for almond milk and use coconut cream instead of heavy cream. The texture changes slightly, but it’s still delicious. Just know the topping won’t get quite as caramelized without butter.

Can I substitute other berries?

Yes! Raspberries, blackberries, or chopped strawberries all work beautifully. Just reduce the sugar slightly if using tart berries.

Is this freezer-friendly?

Totally! Bake it first, then freeze for up to 1 month. Reheat straight from frozen at 350°F for about 30 minutes – cover with foil to prevent over-browning.
