Sweet, Cozy, and Completely Hands-Off
This Crockpot French Toast Casserole brings all the comforting flavors of a classic baked French toast—without needing to turn on your oven. Cubed brioche is soaked in a cinnamon-vanilla egg custard and slow-cooked to golden perfection. Finished with a brown sugar streusel topping, it’s the ultimate make-ahead breakfast for holidays, brunches, or cozy weekends.
Ingredients
For the Casserole:
- 1 (14–16 oz) loaf brioche or challah, cut into 1-inch cubes (day-old preferred)
- 6 large eggs
- 2 cups whole milk
- 1/2 cup heavy cream
- 1/3 cup granulated sugar
- 2 tsp vanilla extract
- 1 1/2 tsp ground cinnamon
- 1/4 tsp nutmeg
- 1/4 tsp salt
For the Streusel Topping:
- 1/2 cup brown sugar
- 1/3 cup all-purpose flour
- 1/2 tsp cinnamon
- 1/4 cup cold butter, cubed
Instructions
1. Prepare the Crockpot
Grease the inside of a 6-quart slow cooker with butter or nonstick spray.
2. Add the Bread
Place cubed brioche or challah into the crockpot.
3. Make the Custard
In a medium bowl, whisk together eggs, milk, cream, sugar, vanilla, cinnamon, nutmeg, and salt. Pour the mixture evenly over the bread cubes. Press down gently to soak.
4. Chill (Optional)
For best results, cover and refrigerate the assembled crockpot insert overnight. If short on time, let soak for at least 30 minutes.
5. Make the Streusel
In a small bowl, mix brown sugar, flour, and cinnamon. Cut in the cold butter using a fork or fingers until crumbly. Cover and refrigerate.
6. Cook
Sprinkle streusel on top just before cooking. Cover and cook on LOW for 4 hours or until the center is set and edges are golden. Avoid opening the lid while cooking.
7. Serve
Scoop into bowls and serve warm with powdered sugar, maple syrup, or fresh fruit.
Tips & Variations
- Add-ins: Mix in blueberries, chopped apples, or chopped pecans before cooking.
