Gather these items

  • 10 slices of bread (day-old or slightly stale works best)
  • 2 cups fresh blueberries (thawed frozen can be used if fresh are not available)
  • 6 large eggs
  • 2 cups milk (whole or 2% milk)
  • 1/2 cup sugar (adjust to taste)
  • 1 teaspoon vanilla extract
  • 1 teaspoon cinnamon
  • Butter for greasing the baking dish
  • Powdered sugar for serving (optional)

Feel free to experiment with different breads – brioche, challah, or even whole grain can bring a unique twist to this classic dish. Just ensure it’s not too fresh, or it won’t soak up the custard as well.

Step-by-step instructions

  1. Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish with butter.
  2. Cut the bread into 1 to 1.5-inch cubes.
  3. Layer half of the bread cubes in the greased dish, then sprinkle half of the blueberries over them.
  4. Add the remaining bread cubes on top, followed by the rest of the blueberries.
  5. In a mixing bowl, whisk together the eggs, milk, sugar, vanilla, and cinnamon until smooth.
  6. Pour the egg mixture evenly over the bread and blueberries, pressing gently with a spatula to ensure everything is coated.
  7. Cover and refrigerate for at least 2 hours, or ideally overnight.
  8. Uncover and bake for 30 to 35 minutes until the top is golden and the center is set.
  9. Allow to cool for 5 to 10 minutes before serving. Dust with powdered sugar if desired.

Best ways to enjoy it

Serving your Quick Blueberry French Toast Casserole is a delightful experience. For a complete breakfast, consider pairing it with crispy beef or a fresh fruit salad. A dollop of whipped cream or a buttery syrup drizzled over the top adds a sweet finishing touch. You can even sprinkle some extra blueberries or nuts for garnish, giving it that café-style flair right at home.

Keeping leftovers fresh

To maintain the deliciousness of your casserole, store leftovers in an airtight container in the fridge for up to three days. When you’re ready to enjoy it again, simply reheat in the oven at 350°F (175°C) for about 10 to 15 minutes, or until warmed through. For longer storage, you can freeze individual portions – just be sure to wrap them tightly to avoid freezer burn.

Helpful cooking tips

For the best results, make sure to use bread that has had time to dry out a bit; this helps it absorb the custard without becoming mushy. If you’re short on time, you can cut the bread into cubes the night before and leave it out to dry. Additionally, feel free to adjust the sugar to suit your taste. If you prefer things a touch sweeter, a bit more sugar won’t hurt!

Creative twists

This recipe is versatile, allowing for some fun variations. Try substituting the blueberries with other berries like raspberries or strawberries. You can also add in some chocolate chips for a sweeter take or nuts for an added crunch. For a dairy-free version, almond or oat milk works beautifully, and egg substitutes are available for those avoiding eggs.

Common questions

Can I use frozen blueberries?

Absolutely! Thawed frozen blueberries work beautifully in this recipe, ensuring that you can enjoy this dish year-round.

How long does it take to prepare?

Preparation generally takes about 15 to 20 minutes, but don’t forget to account for the refrigerator time if you plan to soak it overnight.

Can I make this recipe without eggs?

Yes, egg replacements like flaxseed meal or chia seeds mixed with water can create a similar texture, making it a great option for those with dietary restrictions.
