Ingredients
- 1 loaf (14–16 ounces) brioche, cut into 1-inch slices
- 6 large eggs
- 1½ cups heavy cream
- ½ cup whole milk (or additional heavy cream)
- ¾ cup packed light brown sugar
- 2 teaspoons pure vanilla extract
- 2 tablespoons Grand Marnier (or another orange liqueur)
- ½ teaspoon ground cinnamon (optional)
- ¼ teaspoon fine sea salt
- 2 tablespoons unsalted butter, softened (for greasing the slow cooker)
- 2–3 tablespoons granulated sugar (optional, for a brûlée-style topping)
Instructions
Step 1: Prepare the Slow Cooker
Generously grease the bottom and sides of a 5- to 6-quart slow cooker with the softened butter.
Step 2: Arrange the Bread
Place the brioche slices inside the slow cooker in slightly overlapping layers or stand them upright if your slow cooker is deep.
Arrange the bread evenly without packing it too tightly.
Step 3: Make the Custard
In a large mixing bowl, whisk together:
- Eggs
- Heavy cream
- Whole milk
- Brown sugar
- Vanilla extract
- Grand Marnier
- Cinnamon (if using)
- Salt
Whisk until the sugar dissolves and the mixture is smooth.
Step 4: Soak the Bread
Slowly pour the custard evenly over the brioche slices.
Use the back of a spoon or your hands to gently press the bread into the custard so every slice absorbs the mixture.
Let the bread rest for 10–15 minutes before cooking.
Step 5: Slow Cook
Cover and cook until the custard is fully set and the center is no longer liquid.
- LOW: 3–4 hours
- HIGH: 1½–2 hours
Avoid lifting the lid during cooking.
Step 6: Optional Brûlée Finish
If you’d like a caramelized topping, sprinkle the granulated sugar evenly over the cooked French toast.
Place it briefly under a broiler or caramelize the sugar with a kitchen torch until golden and crisp.
Step 7: Serve
Allow the French toast to rest for 5–10 minutes before serving.
Top with your favorite garnishes and enjoy warm.
