Step-by-Step Recipe for Blueberry French Toast Casserole
Now for the fun part—assembling and baking your casserole!
Step 1: Prepare the Bread
Cut a loaf of slightly stale bread into small cubes. Stale bread is better because it soaks up the custard without getting too mushy. Spread the bread evenly in a greased 9×13-inch baking dish so it covers the bottom.
Step 2: Make the Custard
In a large bowl, whisk together six eggs until smooth. Slowly add two cups of milk, one cup of heavy cream, half a cup of sugar, and a teaspoon of vanilla extract. Keep whisking until it’s all mixed together with no lumps.
Step 3: Put it Together
Pour the custard over the bread cubes in the dish, making sure all the bread gets coated. Press down gently with a spatula to help the bread soak it up. Sprinkle fresh or frozen blueberries on top, spreading them evenly.
Step 4: Let it Chill
Cover the dish with plastic wrap and put it in the fridge for at least two hours, or overnight if you can. This helps the bread absorb the custard and makes the flavors even better.
Step 5: Bake It
Preheat your oven to 350°F (175°C). Take off the plastic wrap and place the dish in the oven. Bake for 45-50 minutes, until the top is golden brown and the center is set but still a bit soft.
Step 6: Serve and Enjoy
Take the casserole out of the oven and let it cool for 10 minutes. Add powdered sugar, maple syrup, or whipped cream on top if you like. Cut into pieces, serve warm, and enjoy your delicious Blueberry French Toast Casserole!
Serving Ideas
This casserole is incredibly versatile and pairs well with a variety of sides and toppings. Here are some ideas to elevate your meal further:
- Fresh Fruit Medley: Add a mix of fresh berries, sliced bananas, or orange segments on the side for a burst of freshness and color.
- Yogurt Parfait: Serve with a dollop of creamy vanilla yogurt layered with granola and fruit to complement the casserole’s flavors.
- Savory Bacon or Sausages: Balance the sweetness with crispy bacon strips or savory breakfast sausages.
- Honey-Glazed Nuts: Sprinkle some honey-glazed pecans or walnuts on top for added crunch and a touch of sweetness.
- Iced Coffee or Tea: Pair your dish with a refreshing iced coffee or herbal tea to round out a perfect brunch experience.
Storage Tips and Best Practices
Have leftovers? No problem! Here’s how to store and reheat your casserole:
- Refrigerator: Store in an airtight container for up to 3-4 days.
- Freezer: Wrap individual portions tightly in plastic wrap and store in a freezer bag for up to 2 months.
- Reheating Tips: Warm in the oven at 350°F until heated through or microwave individual servings for 1-2 minutes.
These tips ensure no slice goes to waste!
Pro Tips for the Perfect Blueberry French Toast Casserole
Want stellar results every time? Follow these expert suggestions:
- Use Stale Bread: Slightly stale bread absorbs the egg mixture better, resulting in a richer, creamier texture. Fresh bread may become too soggy.
- Fresh or Frozen Blueberries: Fresh blueberries are ideal, but frozen ones work just as well. Make sure to thaw and drain frozen berries to avoid excess moisture.
- Chill Overnight: For the best flavor, allow the casserole to chill in the refrigerator overnight. This gives the bread time to soak up all the delicious custard.
- Dust with Powdered Sugar: A light sprinkle of powdered sugar on top not only enhances the presentation but adds a touch of sweetness to complement the berries.
- Test for Doneness: Ensure the center is set by inserting a knife and checking if it comes out clean. This prevents undercooked casserole in the middle!
FAQ’s
Can I use a different type of bread?
Yes, you can! Brioche, challah, or even French bread work wonderfully in place of the suggested bread. Just ensure the bread is slightly stale for the best texture and flavor absorption.
Can I make this without heavy cream?
You can replace heavy cream with additional milk or a non-dairy alternative, though the dish will be slightly less rich.
Is it possible to make this dairy-free?
Yes, simply use dairy-free milk and a plant-based butter substitute to make this dish completely dairy-free.
What’s the best way to reheat individual portions?
The best way to reheat individual portions is to use a microwave, heating in short increments while covering the dish to retain moisture. For a crispier texture, you can reheat in an oven at 350°F until warmed through.
