Quick Answer
This casserole succeeds because the bread is dried first, then given enough time to absorb the custard completely. Blueberries and lemon zest keep the finished bake from tasting too heavy, while butter on top helps the edges brown.

Nutrition Information
Room Temperature Matters
Always bring your eggs and dairy-free alternatives to room temperature before mixing. Cold ingredients create lumps and uneven texture in gluten-free batters.
Don't Skip the Resting Step
Gluten-free flours like almond flour absorb moisture slowly. Let your batter rest for 5–10 minutes before baking for a significantly better crumb structure.
Storage Instructions for Gluten-Free Blueberry French Toast Casserole
Refrigerate leftovers for up to 3 days. Reheat slices in the microwave or oven until just warm.
Gluten-Free Blueberry French Toast Casserole Troubleshooting
Why is the center soggy?
Fresh bread and too short a chill time leave excess liquid trapped in the middle.
Dry the bread cubes first and let the assembled casserole rest overnight whenever possible.
Why did my blueberries all sink?
If they are added only to the custard, they can drop to the bottom during the soak.
Layer the berries directly over the bread before pouring on the custard.
