This Crock Pot French Toast Casserole is a warm, comforting, and indulgent breakfast that I love making when I want something special without the stress of standing over the stove. The bread soaks up a rich custard mixture of eggs, milk, vanilla, and cinnamon, then cooks low and slow until fluffy and golden. A buttery brown sugar topping adds just the right amount of sweetness, and the powdered sugar glaze ties everything together beautifully.

Why You’ll Love This Recipe

I like how easy this recipe is to prepare ahead of time. I can assemble it the night before, then let the slow cooker do all the work in the morning. It’s perfect for holidays, weekend brunches, or whenever I want to treat my family to something sweet and cozy. I also love that I can change up the bread or toppings depending on what I have on hand, so it never gets boring.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

French Toast

1 (16-oz) loaf French bread
2 cups whole milk
½ cup sugar
2 tsp vanilla extract
6 large eggs

Topping

1 tsp ground cinnamon
¼ cup all-purpose flour
¼ cup brown sugar
¼ cup butter, softened
¼ tsp cinnamon

Glaze

¾ cup powdered sugar
2 Tbsp milk
¼ tsp ground cinnamon

Directions

I whisk together the eggs, milk, sugar, vanilla, and cinnamon in a large bowl.
I cut the loaf of French bread into bite-sized cubes and toss them into the custard mixture. I let the bread soak for about 30 minutes, stirring occasionally so every piece absorbs the mixture.
I spray a 6-quart slow cooker with nonstick cooking spray, then pour in the soaked bread cubes.
I mix the brown sugar, flour, cinnamon, and softened butter, then sprinkle it over the bread mixture.
I cover and cook on HIGH for 1⅓–2 hours or on LOW for about 4 hours, until the eggs are set.
Finally, I stir together powdered sugar, milk, and cinnamon to make the glaze, then drizzle it over the casserole before serving.

Servings and timing

This recipe serves 8 people. It takes about 10 minutes of prep time and 1 hour 30 minutes of cooking time on HIGH, or 4 hours on LOW.

Variations

I sometimes swap French bread with brioche, challah, or sourdough for a different flavor and texture.
For extra indulgence, I like to add chocolate chips or a swirl of cream cheese before cooking.
Fresh berries, nuts, or even a drizzle of caramel sauce make excellent toppings.
If I want a lighter version, I use reduced-fat milk and cut back on the sugar in the glaze.

Storage/Reheating

I store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, I microwave individual servings until warm. If I want to freeze it, I let the casserole cool completely, then store portions in a freezer-safe container for up to 3 months. I thaw in the refrigerator overnight before reheating.

FAQs

Can I make this French toast casserole ahead of time?

Yes, I assemble the casserole the night before, refrigerate it, then cook it in the morning.

Can I double the recipe?

Yes, as long as it fits in my slow cooker. The cook time may be slightly longer.

What kind of bread works best?

I like using crusty French bread, but brioche, challah, Italian bread, or sourdough all work well.

Can I cook this overnight?

Yes, if my slow cooker switches to “warm” after the cook time ends. Otherwise, it could overcook.

How do I keep the casserole from being soggy?

I make sure to use day-old or slightly stale bread so it soaks up the custard without turning mushy.

Conclusion

This Crock Pot French Toast Casserole is one of my favorite make-ahead breakfasts. I love how simple it is to prepare, yet it feels indulgent enough for holidays or special gatherings. The combination of fluffy bread, warm cinnamon, and sweet glaze makes it a dish I keep coming back to, whether I’m hosting brunch or just treating my family to something cozy on a weekend morning.
