Gluten-free French Toast Casserole is a special breakfast treat with the flavors of classic french toast. This delicious and easy gluten-free breakfast casserole has a cinnamon streusel topping and also blueberries!
Preheat oven to 375°F. Cut bread into 1-inch cubes. Toast on a non-stick baking sheet for 15-20 minutes or until bread is toasted and lightly brown. Remove and place bread cubes in a greased 8x10-inch or 2-Qt casserole dish.
Whisk together the eggs, milk, sugar, vanilla, and cinnamon. Pour over the toasted bread cubes. Lightly toss to coat the bread. Cover and refrigerate overnight.
To make the streusel topping, use a pastry blender to cut together the flour, brown sugar, cinnamon and butter into a mixture that resembles coarse crumbs. Put in a small container or cover the bowl and refrigerate until ready to bake the casserole.
To Bake the Casserole:
Preheat oven to 375°F. Remove the casserole and topping from the refrigerator while the oven is preheating.
Sprinkle the streusel topping over the casserole. Scatter the blueberries on top.
Bake for 40 minutes or until the casserole is set in the center and lightly browned on top. Serve warm with a drizzle of maple syrup.
