Ingredients You’ll Need

Every ingredient in Slow Cooker French Toast Casserole counts—there’s nothing extra, just pure flavor and texture magic. With these simple staples, you’ll create a dish that’s comforting, festive, and bound to be a new brunch favorite.

• Italian bread: Hearty, slightly chewy, and soaks up the custard perfectly—let it stale overnight or toast it to ensure the best texture.
• Large eggs: The essential base of the custard—six eggs ensure richness without becoming too eggy.
• Milk: Creamy 2% milk delivers the ideal balance of silky texture and richness.
• Cinnamon: Divide it between the custard and topping for that signature warm, sweet flavor throughout every bite.
• Salted butter: Adds fat and flavor to the brown sugar topping, delivering those classic French toast caramelized edges.
• Brown sugar: For sweetness and a touch of molasses depth; adjust to taste for extra indulgence.
• Vanilla extract: Just a dash brings out the flavors and ties everything together beautifully.
• Powdered sugar: For dusting at the end—makes every serving feel special and adds a delicate sweetness.

How to Make Slow Cooker French Toast Casserole

Step 1: Dry Out the Bread

Start by cubing your bread into chunky 1-inch pieces—this ensures the casserole has body and doesn’t get mushy. To let your bread fully absorb the custard, dry it out either by spreading the cubes on a baking sheet and toasting at 170°F for 30 to 60 minutes, or by simply leaving them out overnight. The drier your bread, the more deliciously fluffy the final dish.

Step 2: Make the Custard Mixture

In a large bowl, whisk together your eggs, milk, 1 teaspoon of cinnamon, and vanilla. This is where the Slow Cooker French Toast Casserole gets all its comforting flavor and luscious texture. Be sure to mix well so the eggs are fully incorporated and the cinnamon is distributed evenly.

Step 3: Soak the Bread

Add the stale bread cubes to the custard, tossing gently so every piece gets coated. Cover tightly with plastic wrap and refrigerate for at least 4 hours—or overnight if you want maximum flavor and convenience. The resting time lets the bread soak up all that custardy goodness!

Step 4: Make the Brown Sugar Topping

Mix together your softened butter, brown sugar, and the remaining teaspoon of cinnamon with a pastry cutter or fork until crumbly. This mixture will melt into gooey, caramelized pockets during slow cooking, giving the Slow Cooker French Toast Casserole its signature spiced top.

Step 5: Assemble in the Slow Cooker

When you’re ready to cook, give your slow cooker a light spray with non-stick spray, then pile in the soaked bread mixture. Scatter the brown sugar-butter mixture evenly across the top. This ensures every bite is packed with flavor and a bit of crunch.

Step 6: Cook Low and Slow

Cook on LOW for 4 hours or HIGH for 2 hours—just until the center is set and the edges have a little crispness. Every slow cooker is a bit different, so start checking around the minimum time. Turn the slow cooker to WARM, remove the lid, and rest for 15 minutes to let the casserole set before serving.

Step 7: Finish and Serve

Right before serving, dust the casserole generously with powdered sugar. This step transforms Slow Cooker French Toast Casserole from cozy to celebration-worthy! Top with berries, syrup, or any favorite finishing touch.

How to Serve Slow Cooker French Toast Casserole

Garnishes

A final flurry of powdered sugar is non-negotiable—it’s what makes each portion look like it came from a fancy brunch spot. Fresh berries (especially raspberries, strawberries, or blueberries), a drizzle of pure maple syrup, or even a dollop of whipped cream will make this dish even more special and colorful.

Side Dishes

To round out your meal, consider serving your Slow Cooker French Toast Casserole with crispy bacon or breakfast sausage for a savory edge. A big bowl of mixed fruit salad or a side of creamy yogurt cuts through the sweetness and balances the casserole beautifully.

Creative Ways to Present

For brunch gatherings, try scooping individual servings into cute ramekins or mugs, then top each one with unique extras: toasted pecans, caramel sauce, or a spoonful of lemon curd. If you’re hosting, set up a “French toast bar” where guests can customize their toppings for a personal touch!

Make Ahead and Storage

Storing Leftovers

If you somehow manage to have leftovers, let the casserole cool to room temperature, then transfer it into an airtight container. It keeps well in the refrigerator for up to four days, making it perfect for grabbing a quick, delicious breakfast during busy mornings.

Freezing

Yes, you can freeze your Slow Cooker French Toast Casserole! Once cooled, wrap individual servings tightly or use a freezer-safe dish. It’ll keep for up to two months. To thaw, leave in the fridge overnight so it remains moist and flavorful.

Reheating

Warm up leftovers in the microwave for a convenient single serving, or pop the whole dish back in the slow cooker on low for 30 minutes if feeding a group. Add a splash of milk before reheating to keep it extra moist, and finish with fresh powdered sugar to revive that made-this-morning taste.

FAQs

Can I use a different type of bread?

Definitely! Brioche, challah, or French bread all work well in Slow Cooker French Toast Casserole. Just make sure the bread is stale or toast it first so it soaks up the custard without getting soggy.

Can I prepare Slow Cooker French Toast Casserole ahead of time?

Absolutely, that’s one of the best perks. Prep everything the night before, let the bread soak overnight in the refrigerator, and all you need to do in the morning is toss it in the slow cooker and add the topping.

My casserole turned out soggy. What went wrong?

If it’s soggy, chances are the bread wasn’t dry enough or there was too much liquid. Be sure to dry the bread thoroughly and measure your milk carefully. Also, don’t skip the resting time after cooking, as it helps firm up the casserole for perfect slices.

Can I double the recipe for a bigger crowd?

You can—but make sure your slow cooker is large enough and be aware the cook time will increase. You want the casserole to be set in the middle, so keep an eye on it and use a thermometer if needed; it should reach about 160°F in the center.

Is it possible to make this dairy-free?

Yes! Substitute your favorite non-dairy milk (like almond, oat, or soy), and use vegan butter or coconut oil in place of regular butter. The Slow Cooker French Toast Casserole will still turn out delicious and creamy.
