The Best Bread For French Toast Casserole
The best French toast casserole starts with sturdy bread.
Great options include:
- Brioche
- Challah
- French bread
- Dinner rolls
- Gluten-free rolls
If your bread feels very fresh, let it sit out for a few hours first. Slightly stale bread soaks up the custard much better.
Why This Recipe Works
- The custard soaks fully into the bread for that classic soft center.
- The blackberries bake down and create sweet jammy pockets throughout.
- The baked top gets golden and lightly crisp.
- The homemade sauce adds even more blackberry flavor.
Can You Make It Overnight?
Yes! Assemble the casserole, cover tightly, and refrigerate overnight. When ready to bake, let it sit on the counter for about 20 minutes while the oven preheats. Then bake as directed. This makes it perfect for holiday mornings.
Tips For The Best Blackberry French Toast Casserole
- Use slightly stale bread for the best texture.
- Let the bread sit in the custard for at least 15 minutes before baking.
- Do not skip the resting time after baking.
- If the top browns too quickly, loosely tent with foil.
- For extra crisp edges, broil for 1 to 2 minutes at the end.
Storage
- Store leftovers covered in the refrigerator for up to 4 days.
- Reheat in the oven at 300°F until warmed through.
- You can freeze individual portions for easy breakfasts later.

Instructions
Make the Blackberry French Toast Casserole

Make the Blackberry Sauce

- Allow it to cook for 10 minutes, until the blackberries begin to break down and the sauce thickens slightly.
- Spoon the warm blackberry sauce over the French toast casserole when serving.
Notes
- Use sturdy gluten-free rolls so the bread holds its shape after soaking in the custard.
- Make sure the bread cubes are fully coated before layering them in the baking dish.
- Fresh blackberries work best for this recipe because they hold their texture while baking.
- Let the casserole cool for 1 hour before serving so the custard has time to settle.
- The blackberry sauce should be cooked until the berries begin to break down and release their juices.
- For a regular version, use your preferred bread, milk, and butter.
- Store leftovers covered in the refrigerator for up to 4 days.
- Reheat individual portions in the microwave or warm larger portions in the oven at 300°F.
