How to Make Slow Cooker French Toast Casserole
Prepare the Bread: Cube stale bread into 1-inch pieces and allow them to dry out either overnight or in a low oven for a few minutes. Stale bread helps absorb the custard and enhances the texture.
Make the Custard: In a mixing bowl, whisk together eggs, milk, 1 teaspoon of cinnamon, and vanilla extract until fully combined. This mixture will be the delicious custard that bathes the bread.
Combine Ingredients: Toss the dry bread cubes gently in the custard, making sure all pieces are well coated. This ensures every bite is rich and flavorful.
Chill: Cover the bowl tightly and refrigerate for at least 4 hours or, better yet, overnight. This soaking time allows the flavors to meld beautifully.
Prepare the Topping: In a small bowl, mix softened butter, brown sugar, and the remaining cinnamon until crumbly. This topping will add a delightful crunch and sweetness.
Load the Slow Cooker: Spray your slow cooker with non-stick spray, then add the soaked bread mixture. Sprinkle the brown sugar topping evenly over the top.
Cook: Set the slow cooker on LOW for 4 hours or HIGH for 2 hours. Be sure to check that the center of the casserole is set and cooked through.
Rest and Serve: Allow the casserole to rest for 15 minutes after cooking. Dust with powdered sugar and serve warm with garnishes like berries or maple syrup for a touch of sweetness.
Optional: For added flair, consider serving with fresh fruit or a dollop of whipped cream.
