How to Make Crockpot French Toast Casserole Recipe
Step 1: Prepare the Bread
Start by cubing your brioche bread into 1-2 inch pieces. This size is perfect for soaking up the custard without falling apart. Place all the cubes into the bottom of a greased slow cooker insert, spreading them evenly to create a sturdy base for your casserole.
Step 2: Mix the Custard
In a large bowl, whisk together the beaten eggs, whole milk, vanilla extract, cinnamon, nutmeg, and a pinch of salt until fully blended. This custard mixture is where all the flavors unite and develop, offering richness and those classic French toast spices.
Step 3: Combine and Soak
Pour the custard evenly over the cubed bread, then gently press down on the bread with a spatula to ensure it’s fully submerged. Cover the slow cooker and place it in your refrigerator for an hour or even overnight. This soaking step is key; it allows the bread to absorb all those delightful flavors.
Step 4: Add the Topping
Once soaked, sprinkle the light brown sugar evenly over the top of the bread mixture. Dot the casserole with the cubed butter pieces—these will melt during cooking and form a luscious, caramelized glaze that you won’t be able to resist.
Step 5: Slow Cook to Perfection
Cover the slow cooker and cook on high for 1-2 hours or on low for 2-4 hours. You’ll know it’s done when the custard is puffed and set, and the top has a beautiful golden finish. The slow cooking method ensures that every bite is tender and infused with warm spice and buttery sweetness.
Step 6: Serve and Enjoy!
Serve your Crockpot French Toast Casserole Recipe immediately for the best texture and taste. This dish shines when topped with your favorite flavors like maple syrup or fresh fruit compote.

Garnishes
A simple dusting of powdered sugar adds a whimsical look and a hint of sweetness, while fresh berries or sliced fruit add freshness and a pop of color. For extra indulgence, drizzle with warm maple syrup or a dollop of whipped cream.
Side Dishes
Pair this casserole with crispy bacon or savory sausage links to balance the sweetness. A fresh green salad with a light vinaigrette can also be wonderful for a brunch feast that feels hearty but well-rounded.
Creative Ways to Present
For entertaining, serve the casserole in individual ramekins straight from the crockpot or create a breakfast buffet with toppings and sides so everyone can customize their plate. Wrapping cinnamon sticks or nice sprigs of fresh mint beside each portion adds a charming touch.
Make Ahead and Storage
Storing Leftovers
Leftover Crockpot French Toast Casserole Recipe stores beautifully in an airtight container in the refrigerator for up to 3 days. This makes it a great option for quick breakfasts during busy weekdays.
Freezing
You can freeze leftovers by portioning the casserole into freezer-safe containers. Thaw overnight in the refrigerator before reheating. Freezing is convenient and maintains the dish’s custardy goodness.
Reheating
Reheat individual portions in the microwave for about 1-2 minutes or until warmed through. Alternatively, use a 350°F oven for 10-15 minutes, covered loosely with foil to keep the casserole moist while heating.
FAQs
Can I use bread other than brioche?
Yes, but brioche is preferred for its buttery texture and flavor. You can substitute challah or French bread, but avoid very soft or fresh bread as it won’t hold up as well during soaking and cooking.
Do I need to soak the bread overnight?
While soaking overnight creates the best texture and flavor, soaking for just one hour in the refrigerator is effective and convenient if you’re pressed for time.
Can this recipe be made vegan?
You can try using plant-based milk and egg replacers, but results may vary. The custardy texture depends on eggs and dairy, so be prepared for a different consistency.
Is it possible to make the casserole ahead fully cooked?
You can cook it in advance and keep it warm in the slow cooker on low for up to 2 hours, but for best texture and freshness, it’s recommended to serve shortly after cooking.
What are some toppings to try beyond syrup and fruit?
Try nut butters, toasted nuts, honey, or even a sprinkle of shaved chocolate. These extras can add unique flavor and texture twists to your Crockpot French Toast Casserole Recipe experience.

- 1 teaspoon vanilla extract
- 1½ teaspoons ground cinnamon
- ¼ teaspoon ground nutmeg
- Pinch of salt

- ½ cup light brown sugar
- ¼ cup unsalted butter, cut into cubes
Instructions

- Mix the custard: In a large bowl, whisk together the beaten eggs, whole milk, vanilla extract, ground cinnamon, ground nutmeg, and a pinch of salt until fully combined.
- Soak the bread: Pour the custard mixture evenly over the cubed bread. Use a spatula or your hands to press the bread down gently, ensuring it is submerged in the liquid. Cover the slow cooker insert and refrigerate for 1 hour to allow the bread to soak absorb the custard thoroughly. Alternatively, you can cover it and chill overnight for deeper flavor.
- Add the topping: After soaking, sprinkle the light brown sugar evenly over the top of the bread. Dot the surface with small cubes of unsalted butter for richness and caramelization during cooking.
- Cook the casserole: Cover the slow cooker with its lid and cook on high for 1-2 hours or on low for 2-4 hours. The casserole is done when the egg mixture is fully set and the bread is tender and custardy.

Notes
- Day-old brioche bread works best as it soaks up the custard better without becoming too mushy.
- Refrigerating the mixture to soak allows deeper flavor penetration into the bread.
- Cooking times may vary depending on your slow cooker; start checking doneness at 1 hour on high or 2 hours on low.
- For a gluten-free version, substitute the brioche with gluten-free bread.
- Serve with fresh fruit or nuts to add texture and balance the sweetness.
