Ingredient Notes 

Here are the simple ingredients to make your French toast:

• bread - we like brioche bread for its soft, fluffy texture, but Texas toast, French bread, and challah bread cubes also work. The best way to make the recipe is with stale bread.
• large eggs
• whole milk - to create the creamy custard mixture. Swap with half and half or cream for a more decadent casserole.
• real maple syrup - not imitation pancake syrup.
• pure vanilla extract - pure vanilla tastes so much better than imitation vanilla extract.
• pecans - an optional ingredient if you like a little nutty flavor and crunch.
• salt - just a hint to bring the sweet flavors together.
• ground cinnamon - the spice that's the star of the dish.
• ground nutmeg - another warm spice that combines well with cinnamon.

You can find the full ingredient list and instructions in the printable recipe card below.

Topping ingredients

• butter - salted butter is what we like to use.
• brown sugar - light or dark brown sugar is okay.
• ground cinnamon

And, of course, don't forget the toppings after it’s cooked! 

Maple syrup, powdered sugar, fresh fruit, and even a dollop of whipped cream (or vanilla ice cream) make delicious additions to this Crock Pot French Toast.

Substitutions

• If you don't have regular milk or have sensitivities, almond or soy milk can also work. 
• You can substitute heavy cream for whole milk if you want a more decadent French Toast Casserole recipe.
• For a gluten-free option, try using gluten-free bread instead of regular bread. 
• Feel free to add any extra flavors or mix-ins you like, such as chocolate chips, diced apples, or chopped nuts. We love pecans and walnuts. 

Step-By-Step Instructions

STEP 1 - prep crock pot

Grease your slow cooker insert with nonstick cooking spray or butter. 

STEP 2 - prepare bread

Cut the loaf of bread or slices into 1-inch cubes. Then, layer it with the pecans (if using) in the crockpot. 

PRO TIP: This recipe is best with stale bread. If you don't have any on hand, simply place the cut cubes on a baking sheet and place them in a 250-degree F. oven for 10-minutes.

STEP 3 - make egg custard

Whisk the 8 eggs, 3 cups milk, ¼ cup real maple syrup, 1 tablespoon pure vanilla extract, 1 teaspoon salt, 2 teaspoons cinnamon, and ½ teaspoon nutmeg in a large bowl.

STEP 4 - combine custard with bread

Pour the egg mixture over the cubed bread and nuts in the slow cooker. Stir gently to coat the bread. 

If possible, let it sit for a couple of hours so the bread is saturated with the custard.

STEP 5 - make the topping

To make the topping, cut the butter into small pieces, set it aside, and then mix brown sugar and cinnamon in a small mixing bowl. 

Next, sprinkle the brown sugar mixture over the top of the soaked bread and top that with the butter pieces. 

NOTE: If you need to make this casserole ahead, you can place the recipe in the refrigerator after step 5 until ready to cook. Please bring the crock insert to room temperature before placing it in your slow cooker, or it can crack!

STEP 6 - cook

Cover the slow cooker with the lid and cook on HIGH for 2 to 2 ½ hours or the LOW setting for 3 to 4 hours. 

When done, serve your slow cooker french toast with warm maple syrup, powdered sugar, or fresh fruit. 

PRO TIP: To keep your crock pot french toast casserole warm while everyone is eating, use the ‘warm setting’ on your slow cooker. 

Cooking tips and tricks

• Although not totally necessary, stale bread makes the best French toast. You can either leave it at room temperature overnight or bake it in a 250-degree F. oven for 10 minutes.
• Try topping your breakfast casserole with a sprinkle of cinnamon or powdered sugar, and drizzle the top with pure maple syrup or honey for added flavor.
• YouDon'tprepare the bread and custard mixture the night before and let it sit in the fridge overnight for even more flavorful French. Don't forget to take the insert out of the refrigerator and let it come to room temperature before placing it in the slow cooker so it doesn't crack.
• All models of crock pots cook differently. Get to know your slow cooker and adjust the time accordingly.
