Preparing Blueberry French Toast Casserole
If you’re looking for the ultimate brunch recipe that combines ease with deliciousness, you’ve landed in the right place. This Blueberry French Toast Casserole isn’t just a treat for your taste buds; it's also a breeze to prepare. Let’s break it down step by step!
Prepare the baking dish
To start, you'll want to grab your favorite baking dish—ideally, a 9x13-inch pan will do the trick. Generously grease it with butter or nonstick spray to ensure your casserole slides out easily after baking. A well-prepared dish is key to achieving that golden-brown crust you crave!
Cube the bread
Next up, you'll need to transform your bread of choice into delightful little cubes. You can use French bread, brioche, or even challah for a richer flavor. Aim for about 1-inch pieces; this size allows the bread to soak up all the yummy egg mixture wonderfully. Place these cubes in the prepared dish, spreading them out evenly, and make it visually appealing.
Combine the egg mixture
In a large mixing bowl, whisk together eight large eggs, two and a quarter cups of whole milk, half a teaspoon of ground cinnamon, three-quarters of a cup of packed light brown sugar, and a tablespoon of pure vanilla extract. This mixture is the star of the show, and you'll want it to be smooth and well combined—just think of that sweet, custardy flavor soaking into the bread!
Assemble the casserole
Once your egg mixture is ready, pour it evenly over the prepared cubed bread. Make sure every piece gets a generous splash of that luscious liquid. Combine with one cup of blueberries, covering the top with these juicy gems. After you've added the blueberries, cover the dish tightly and place it in the refrigerator; letting it soak overnight allows the flavors to meld beautifully. If you're short on time, let it sit for a minimum of three hours.
Prepare the streusel topping
While the casserole is soaking, let’s whip up the streusel topping for that delightful crunch. In a medium bowl, mix together one-third cup each of brown sugar and all-purpose flour, along with half a teaspoon of ground cinnamon. Now, the fun part: cut in six tablespoons of cold, cubed unsalted butter until the mixture turns crumbly. Sprinkle this delicious topping over the casserole right before baking.
Bake to perfection
Preheat your oven to 350°F (177°C) and pop the casserole in after it's been chilled. Bake for 45 to 55 minutes, or until the top is beautifully golden brown and the edges are slightly puffed. If you're like me and enjoy a softer texture, you might prefer the shorter bake time.
And there you have it—the perfect Blueberry French Toast Casserole! Serve it warm with a drizzle of maple syrup or a dusting of confectioners’ sugar. Your brunch guests will be raving about it, and you'll love how simple it was to prepare!
