The holidays have arrived and we are doing tons of baking. The girls have decorated their gingerbread houses and our tree has been trimmed. Our weekdays are so rushed, that I like to make a special breakfast treat on the weekends. 

My family loves French toast, and I’ve found an even simpler and tastier way to make it. This vegan and gluten free baked French toast casserole takes just a few minutes to prepare. It’s lightly sweetened with banana and maple syrup and topped with a crumble oat crisp topping. Soft on the inside, and crunchy on the top, a baked French toast casserole is sure to be a hit for a holiday breakfast. Let’s check out how it is made!

Gluten Free Vegan Bread 

Little Northern Bakehouse sent me the most delightful box filled with their delicious breads. Are you wondering if plant-based gluten free bread can really be delicious? I was too, but was so pleasantly surprised by just how tasty this Cinnamon & Raisin bread is. I love that it’s made with clean, Non-GMO ingredients. This Cinnamon & Raisin bread is perfect for a baked French toast casserole, while I love their other breads for sandwiches and other savory recipes.

Ingredients for a baked french toast casserole that's vegan and gluten free.

Baked French Toast Casserole Ingredients

I wanted to keep this recipe 100% plant based. So while French toast casseroles traditionally use about a half dozen eggs, I made the “custard” out of plant-based milk, flax meal and banana. Banana is already sweet, so just a touch of maple syrup is needed and a couple of teaspoons of cinnamon and vanilla. For added texture and crunch, I love adding a big handful of walnuts. I am just loving these clean natural ingredients. 

Vegan Gluten Free French Toast Casserole Filling

I add the filling ingredients right into the blender. It doesn’t get much easier! 

Let that milky flax-banana mixture sit while you cut up the bread. 

I used nearly the whole loaf of Little Northern Bakehouse’s Cinnamon & Raisin bread. The precise measurement doesn’t really matter, you’ll just want to fill up an 8-inch square baking dish.

Pour the liquid ingredients over the bread and toss to coat. 

Baked French Toast Oat Crumble Topping

To keep this recipe 100% gluten free, you’ll want to be sure to buy gluten free oats. While oats are naturally gluten free, they are often contaminated during processing. Crumble together the oats, coconut sugar, and soft vegan butter in a small bowl. Top the bread with the oat mixture and cover with foil. 

Once the french toast casserole has set, it’s ready! Serve with berries and maple syrup.
