Cranberry French Toast Casserole

Cozy, baked French toast casserole is a mouthwatering, comforting breakfast that you can make right now or the night before. Butter, maple syrup, and cranberries are simmered together in a cast iron skillet, topped with homemade sourdough bread and a creamy custard, then baked to completion.

Throughout the week, I typically make simple breakfasts like oatmeal, einkorn cream of wheat, or a breakfast smoothie. 

But during these long, cold, winter days, I just crave something warm and cozy. This baked cranberry French toast casserole hits the spot. 

During the holidays, I stock up on cranberries (they store really well in the freezer if you don’t plan on eating them right away). They are such a delicious and under-appreciated fruit. 

They aren’t just for making a sauce to accompany turkey on Thanksgiving or Christmas. Cranberries are incredibly versatile year round, and particularly delicious in this sourdough cranberry bread.

I’m here to normalize the use of cranberries all year long.

The combination of sweet and sour cranberries, plus the deliciously tangy flavor of the sourdough bread, creates an incredible combination that will cause your taste buds to sing.

Tips for Making Cranberry French Toast Casserole:

• You can use whatever milk you have on hand: cow, goat, coconut, almond. Any will work. I like using whole, raw milk, either from our own goats or cow milk we pick up from a local farm.
• I use homemade sourdough bread in this recipe. While I love making bread from scratch multiple times a week, I know this isn’t practical for everyone. You can easily use a store-bought, crusty, sourdough bread instead of making it yourself.
• If you know you have a busy morning ahead, you can easily make this recipe the night before. See below to find the instructions on how to do so.

How To Make Cranberry French Toast Casserole

The day before, make sourdough bread.

Preheat oven to 375 degrees.

Slice and cube a loaf of crusty sourdough bread and set aside. As I said above, I love using homemade, sourdough artisan bread, but if you haven’t made any, you can use your favorite store-bought crusty bread, whether it be sourdough, French bread, or challah. However, you don’t want to use plain, pre-sliced white bread – it won’t hold its shape. 

In a cast iron skillet over medium heat, add a stick of butter, maple syrup, honey, and cranberries (optional). Cook for a few minutes, until the butter and sweeteners have come to a simmer and the cranberries start to pop open. 

Turn off the stove and add cubed bread over top of the butter mixture.

In a large bowl, create the custard by combining eggs, milk, vanilla, and cinnamon. Stir well.

Pour custard mixture over cubed bread in the skillet. 

Sprinkle cranberries over top evenly (optional).

Bake for 30 minutes, until the custard is set and the tops of the bread chunks start to turn golden brown.
