Step-By-Step Instructions
Preparing the Bread
Start by cutting the gluten-free bread into 1-inch cubes. Spread them evenly in a greased baking dish, taking care to create a nice layer for the custard to soak into.
Making the Custard Mixture
In a large bowl, whisk together the eggs, milk, maple syrup, cinnamon, nutmeg, vanilla extract, salt, and the grated apples until the mixture is smooth and well combined.
Assembling the Casserole
Pour the custard mixture over the bread cubes. Gently toss everything together to ensure even distribution of the apples, pressing down lightly to soak the bread thoroughly and eliminate air pockets.
Chilling and Baking
Cover the dish with plastic wrap and refrigerate for at least 2 hours or overnight for optimal texture. When ready, preheat the oven to 350°F (175°C). Cover the casserole with aluminum foil and bake for 40 minutes. Remove the foil and bake for an additional 10 minutes, or until the top is golden brown.
Tips for the Perfect Casserole
Choosing the Right Bread
For the best results, use slightly stale or toasted gluten-free bread to prevent sogginess. This texture will hold up better in the custard.
Ensuring Even Custard Distribution
To avoid dry spots, press the bread down gently to ensure the custard fully saturates every piece.
Frosting Tips for Balanced Flavor
When preparing the frosting, start with less oat milk and gradually add until you reach your desired consistency. A light drizzle is all you need to avoid overpowering the dish.
Variations and Substitutions
Alternative Bread Options
You can experiment with different gluten-free breads or even use a mixture of bread types for varied flavor and texture.
Non-Dairy Milk Choices
Feel free to substitute any non-dairy milk, such as almond or coconut, to suit your preference.
Add-Ins for Extra Flavor
Add-ins like raisins, nuts, or even a sprinkle of chocolate chips can elevate this casserole to new heights.
How to Store Leftovers
Proper Storage Techniques
Store any leftovers in an airtight container in the fridge for up to 3 days. Ensure it’s well sealed to maintain freshness.
Reheating Instructions
To reheat, place the casserole back in the oven at 350°F (175°C), covered with foil to retain moisture, until warmed through.
