Do you have to use sourdough bread in French toast casserole?

No you don’t! You can use different types of bread, but I personally prefer sourdough since that is what I make most of the time due to the increased health benefits of sourdough fermentation. Plus the sourdough “tang” gives such a good taste to the baked casserole.

Other types of non-sourdough bread that you can substitute: french bread, regular white bread loaf, whole grain bread, and others. I would personally not recommend using a strong bread like rye bread.

Ingredients for Best blueberry sourdough french toast casserole

sourdough bread, cubed (a perfect way to use up bread that is several days old, or bread going stale)
milk
eggs
cream cheese
honey, maple syrup unrefined or other sugar
blueberries, fresh or frozen
salt

Notes:

What types of milk to use? Whole milk, 2% work fine. Don’t use buttermilk or soured milk.
Can you use a non -dairy milk alternative? I have never tried it personally. Although I might try a small batch sometime with almond milk.
Can you replace bread with gluten-free bread? Yes, absolutely!
There is no added sugar in this overnight blueberry french toast casserole, only a small amount of honey.

Here are some health benefits of consuming honey

It is anti-inflammatory
It contains antibacterial and antioxidant agents
It can ease cough and cold irritations

How to make Best blueberry sourdough french toast casserole

Put half the bread cubes in the bottom of a greased 9×13″ pan or other baking dish.

Sprinkle blueberries and cubed cream cheese evenly on top. Place remaining bread cubes over that.

Make egg mixture by whisking eggs, honey, milk and salt together in a medium bowl.

Pour over the bread cubes in the pan. Refrigerate (covered) overnight or at least 2 hours. (Letting it sit helps the bread to absorb the egg mixture).

Pull out in the morning or when ready to bake.

Bake at 350 covered with aluminum foil for 25 minutes then uncovered for an additional 20-30 minutes. You don’t want to over bake or it will be dry.

How to serve?

I enjoy serving this with homemade blueberry sauce, homemade blueberry syrup, maple syrup or a fresh fruit salad and yogurt. I like mine more moist so I pour a little milk over my serving! Dust some powdered sugar on top and mmmmmmmm!

Breakfast sausage or bacon is a great side with this breakfast recipe.

How to store?

Store in an airtight container or covered in the baking pan with plastic wrap or a beeswax wrap. This can also be stored by dividing into individual portions if you’d like.

Tips for making Best blueberry sourdough french toast casserole?

1. For best results, you will want to not miss this important step like I did the first time I made this! Make sure you let this “soak”/refrigerate before baking so that the bread cubes can absorb some of the egg and milk mixture. Otherwise it will take a very long time to bake and may be extremely runny.

2. Day-old bread is great for this recipe, otherwise bread that is partially dried out (stale) works well so that it can absorb more of the “batter” which will prevent your casserole from being too “soggy”

Equipment you may need:

Cutting board and knife
large liquid measuring cup
Mixing bowl
Whisk
9×13″ pan or similar baking dish

Can this be frozen?

I have not personally froze this myself but I hear that others have.

How long does french toast casserole last?

This will last up to a week in the fridge.

Fresh or frozen blueberries?

Either can be used, though frozen blueberries will let out more of their juices while baking which will make for a nicer “blueberry experience”.

Do you have to use sourdough bread?

No you don’t.

Can you replace with gluten-free bread?

Yes

How do you reheat this French toast casserole?

Reheat covered with foil in a toaster oven or regular oven, until warm. (If you don’t cover with foil it will likely dry out.)
