Ingredients You’ll Need
The beauty of this Crockpot French Toast Casserole Recipe lies in its humble yet impactful list of ingredients. Each item plays a pivotal role—whether it’s adding rich creaminess, warm spice, or that all-important custard soak to the bread cubes. Together, they ensure every bite is a perfect harmony of flavor and texture.
- 16 ounces loaf sliced brioche bread: Day-old brioche is ideal because it soaks up the custard without turning mushy.
- 6 eggs (beaten): Eggs are the binding superstar that give the casserole a rich, custard-like texture.
- 2¼ cups whole milk: Whole milk adds creaminess and helps the egg mixture coat the bread evenly.
- 1 teaspoon vanilla extract: A splash of vanilla lifts the flavors and adds a lovely aromatic warmth.
- 1½ teaspoons ground cinnamon: Cinnamon brings that comforting, classic French toast spice note.
- ¼ teaspoon ground nutmeg: Nutmeg adds depth and a subtle earthy sweetness.
- Pinch of salt: Just enough to balance the sweetness and bring out all the flavors.
- ½ cup light brown sugar: Sprinkled on top for a melting, caramelized finish that’s pure magic.
- ¼ cup unsalted butter (cut into cubes): Butter dots keep the top luscious and perfectly golden.
How to Make Crockpot French Toast Casserole Recipe
Step 1: Prepare the Bread
Start by cutting your brioche loaf into 1 to 2-inch cubes—day-old bread is best because it holds together without becoming too soggy after soaking. Lightly grease your slow cooker insert, then add the bread cubes evenly to create the base of your casserole. This step sets the stage for that beautiful custardy bake we’re after.
Step 2: Mix the Custard
In a mixing bowl, beat together the eggs, whole milk, vanilla extract, ground cinnamon, nutmeg, and a pinch of salt until fully combined. This mixture will soak into the bread, infusing it with rich, layered flavors and creating that melt-in-your-mouth texture.
Step 3: Soak the Bread
Pour the custard mixture evenly over the bread cubes in the slow cooker. Press down gently to make sure the bread is well submerged and soaking up all that delicious liquid goodness. Cover and refrigerate for at least one hour; for even better results, let it sit overnight. This soak gives the casserole its signature custard softness.
Step 4: Add the Sweet Topping
Once your bread has soaked, sprinkle the light brown sugar evenly over the top. Dot the surface with cubes of unsalted butter. These simple additions form a golden, caramelized crust during cooking, making every bite irresistibly sweet and buttery.
Step 5: Cook Low and Slow
Cover your slow cooker and set it to high for 1 to 2 hours, or low for 2 to 4 hours. You’re looking for the custard to fully set and the edges to be lightly browned. The slow cooker’s gentle, consistent heat will give you a perfectly cooked French toast casserole with no burnout or uneven spots.
Step 6: Serve and Enjoy
Serve your Crockpot French Toast Casserole Recipe immediately for the best experience. Top with your favorite maple syrup, fresh fruit compote, or a dusting of powdered sugar. Each spoonful will feel like a celebration of comfort food done right.
How to Serve Crockpot French Toast Casserole Recipe

Garnishes
Add a fresh, vibrant touch with berries, sliced bananas, or a dollop of whipped cream. A drizzle of pure maple syrup is classic and perfectly complements the cinnamon and brown sugar flavors. For a bit of crunch, sprinkle toasted nuts like pecans or walnuts on top.
Side Dishes
This casserole pairs wonderfully with crispy bacon or savory sausage for a balanced breakfast spread. A simple side salad with fresh greens or a bowl of mixed fruit rounds out the meal nicely if you want lighter contrasts alongside the richness.
Creative Ways to Present
For a brunch party, serve this casserole buffet-style in the slow cooker so guests can help themselves. Or portion it into individual ramekins before cooking for charming single servings that look extra special on the table. Adding edible flowers or a dusting of cinnamon sugar before serving can also elevate the presentation.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover any leftovers tightly and store in the refrigerator for up to 4 days. The casserole will keep its flavor and texture well, making for delicious next-day breakfasts or snacks.
Freezing
This dish freezes beautifully. To freeze, cool completely, then transfer to an airtight container or freezer-safe bag. It can be frozen for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
Reheat the casserole slices gently in the microwave or oven until warmed through. If reheating in the oven, cover loosely with foil to prevent drying out and bake at 350°F (175°C) for 15-20 minutes.
FAQs
Can I use bread other than brioche?
Absolutely! While brioche is ideal for its tender crumb and rich flavor, challah or thick-cut white bread will also work nicely. Just make sure the bread is sturdy enough to soak the custard without falling apart.
Do I have to soak the bread overnight?
Overnight soaking creates the most custardy texture, but if you’re short on time, one hour in the fridge will still yield delicious results.
Can I prepare this recipe without a slow cooker?
If you don’t have a slow cooker, you can bake the casserole in a 9×13-inch dish at 350°F (175°C) for about 45-55 minutes or until the custard sets and the top is golden.
What toppings go best with Crockpot French Toast Casserole Recipe?
Maple syrup, fresh berries, powdered sugar, and whipped cream are classics. For a twist, try fruit compotes or a drizzle of caramel sauce.
Is this recipe suitable for meal prep?
Yes! It’s perfect for making ahead and having breakfasts ready to go throughout the week, or for hosting brunch with minimal fuss.

Notes
- Day-old brioche bread works best as it soaks up the custard without becoming mushy.
- Refrigeration time for soaking can be extended overnight to save time in the morning and deepen the flavors.
- Use a slow cooker insert large enough (5 quarts or bigger) to allow the casserole to cook evenly.
- Cooking times can vary depending on the slow cooker model, so check for doneness by ensuring the custard is set and no longer jiggly.
- For added texture, sprinkle chopped nuts or dried fruits before cooking.
