Can I make keto French toast casserole the night before?

Yes, this recipe works great as an overnight casserole. Just layer the chaffle cubes in a dish, pour the egg custard over, cover, and chill in the fridge. The flavors soak in better and it bakes up soft and golden the next morning—just like a classic French toast casserole overnight, but keto-friendly.

What’s the best bread substitute for keto French toast?

Keto Chaffles make the best low carb bread swap for French toast. They hold their shape, soak up the egg custard perfectly, and toast up crisp on the outside. You can also use 90 Second Keto Bread, but chaffle bread has better texture for a casserole.

Can I freeze keto chaffle French toast casserole?

Yes, you can freeze it after baking. Let it cool, slice into portions, and wrap each piece in foil or airtight containers. Reheat in the oven or toaster oven for a quick low carb breakfast. It’s one of the easiest keto diet meals to prep ahead and still enjoy later.
