Most common mistakes when making Gluten-Free French toast casserole

There are a few things to watch out for when making this dish so that your French toast casserole turns out perfectly. Here are the most common mistakes:

1. The milk and eggs ratio. The milk and eggs ratio is important to get the right texture. Too much milk will make the casserole soggy, and too many eggs will make it eggy and dry. The ratio should be 3 eggs to 1 cup of milk

2. Not using day-old bread. It would be best to have slightly stale bread to absorb all the delicious custard without getting soggy.

3. Adding too much liquid. This will also make your casserole soggy, so be sure to follow the recipe.

4. Not prepping your pan properly. You must grease your pan generously with butter so the casserole doesn’t stick and fall apart when you try to serve it.

5. Overcooking it. The key to a perfect French toast casserole is to bake it slowly until it’s golden brown on top but still soft and custardy in the middle.

Add-ins and substitutions

When it comes to gluten-free French toast, you can do a few things to make it your own. 

Bread – Choose your favorite bread.  

Fruit – Add extras like thinly sliced apples, berries or raisins.

Milk – for a non-dairy alternative, use almond milk or coconut milk. 


There are so many delicious toppings you can add to this dish! Of course, fresh berries are always popular, but you could also use sliced bananas, diced apples, or any other fruit you have on hand, and a sprinkle of cinnamon sugar or powdered sugar.

A drizzle of pure maple syrup or honey is always a good idea, and for a little extra indulgence, you could top it with whipped cream, vanilla ice cream or vanilla glaze.

Serving suggestions

This gluten free french toast breakfast casserole is delicious as is, but you can kick it up a notch. Serve it with some crispy gluten free bacon or a side of gluten free breakfast sausage for a savory twist.

Nothing is worse than having to throw away perfectly good food, but sometimes leftovers don’t taste as good as they did the first time, especially gluten-free baked goods.

So if you have leftovers, reheating a single serving in the microwave for 30 seconds before serving will bring back the freshly baked texture. Regardless of your dietary needs or preferences, this delicious breakfast dish can be enjoyed by most.
