Slow Cooker French Toast Casserole has only a few ingredients, preps overnight, and is perfect for Christmas morning, brunch, or just a weekend breakfast. Full of cinnamon flavor, this easy crockpot casserole is perfect finished off with a dusting of powdered sugar and some fresh fruit.
Cube the bread into approximately 1" pieces and spread onto a lipped baking sheet. Bake in a 170°F preheated oven for 30-60 minutes, or until dry. Alternatively, you can cube the bread and let it sit out overnight to stale.
1 loaf Italian bread
To prep the casserole
In a large mixing bowl, whisk together the eggs, milk, vanilla, and 1 teaspoon of the cinnamon.
6 large eggs, 2 cups milk, 2 teaspoons cinnamon, ½ teaspoon vanilla extract
Add the stale cubed bread to the egg mixture and stir so all pieces of the bread are fully coated. Cover the bowl with plastic wrap and move it to the fridge for 4-8 hours.
In a small mixing bowl, use a pastry cutter or a fork to cut together the butter, brown sugar, and remaining cinnamon. Cover and put in the fridge as well.
⅓ cup brown sugar, ¼ cup salted butter
To assemble the casserole
When ready, spray a 6 quart slow cooker with non-stick spray and pour in the soaked bread pieces.
Crumble the butter mixture evenly over the top.
Cover and cook on HIGH for 2 hours or LOW for 4 hours, or until the center is set.
Turn the slow cooker to WARM and remove the lid. Let stand for 15 minutes to set before serving.
Top with powdered sugar, syrup, and berries.

Notes
Use a hearty bread like Italian, French, or brioche.
Cook on HIGH for 2 hours—great for early prep and morning serving.
Adjust sweetness: use ⅓ cup brown sugar or ½ cup for extra sweetness.
How to Dry Out Bread
Use stale bread for better absorption of the egg mixture.
Overnight method: Cube bread and let it sit out on the counter overnight to dry.
Quick method: Cube bread, spread on an ungreased baking sheet, and bake at 170°F for 1 hour until dry and slightly crisp.
Every slow cooker runs differently. Times given are a general recommendation and should be tested in your own slow cooker and adjusted as needed.
