Crockpot French Toast Casserole

There’s something nice about waking up to a warm breakfast that’s already cooking away in the crockpot. On busy mornings, or when family is visiting, it takes a lot of the stress out of getting breakfast on the table.

This recipe turns a simple loaf of bread into a cozy breakfast that tastes like you spent much more time on it than you actually did. The bread soaks up a sweet cinnamon and vanilla custard, giving you that classic French toast flavor in an easy casserole form.

I especially like making this for holiday mornings and weekend brunches when everyone seems to wake up at different times. Just add your favorite toppings and serve straight from the crockpot for a breakfast that’s as easy as it is delicious.

Equipment

• 6-quart crockpot: A larger slow cooker gives the casserole enough room to cook evenly without becoming too thick in the center.

• Large mixing bowl: You’ll need plenty of space to whisk together the custard ingredients before pouring them over the bread.

• Whisk: Helps combine the eggs, milk, cream, and seasonings into a smooth custard mixture.

• Measuring cups and spoons: For accurately measuring the ingredients so the casserole has the right texture and sweetness.

• Cooking spray: Keeps the casserole from sticking to the crockpot and makes cleanup much easier.

• Silicone spatula or large spoon: Useful for gently pressing the bread into the custard and serving the casserole once it’s cooked.

Ingredients

• French bread: Slightly stale French bread works best because it soaks up all the custard without falling apart.

• Large eggs: Eggs create the rich custard that gives French toast its classic texture.

• Whole milk: Adds creaminess and helps keep the casserole soft and tender.

• Heavy cream: A little heavy cream makes the custard extra rich and flavorful.

• Brown sugar: Adds sweetness along with a subtle caramel flavor throughout the casserole.

• Granulated sugar: Helps balance the flavors and gives the custard just the right amount of sweetness.

• Vanilla extract: Brings that warm bakery-style flavor that pairs perfectly with cinnamon.

• Ground cinnamon: A must-have ingredient for that cozy French toast flavor.

• Nutmeg: Just a small amount adds extra warmth and depth to the custard.

• Salt: Helps balance the sweetness and brings out all the other flavors.

• Butter, melted: Adds richness and helps create a soft, delicious texture.

Topping

• Brown sugar: Melts into the top of the casserole and creates a sweet cinnamon-sugar finish.

• Cinnamon: Adds an extra layer of warm spice right on top.

• Butter, melted: Helps the topping come together and gives the casserole lightly golden edges as it cooks.

Recipe Instructions

Full measurements and cooking times can be found in the recipe card at the bottom of this post.

Step 1: Spray the inside of a 6-quart crockpot with nonstick cooking spray.

Step 2: Add the cut-up bread cubes to the crockpot and spread them evenly.

Step 3: In a large bowl, whisk together the eggs, milk, heavy cream, brown sugar, granulated sugar, vanilla extract, ground cinnamon, nutmeg, and melted butter until fully combined.

Step 4: Pour the custard mixture evenly over the bread cubes. Gently press the bread cubes down so they will absorb the liquid.

Step 5: In a small bowl, stir together the brown sugar, cinnamon, and melted butter. Sprinkle over the top of the bread cubes.

Step 6: Cover and cook on low for 3 to 4 hours, or until the center is set and the edges are lightly golden. Be sure not to overcook the casserole so it stays soft.

Step 7: Serve warm with maple syrup. Sprinkle the top with powdered sugar for an extra touch.

What to Serve with Crockpot French Toast Casserole

• Fresh berries: Strawberries, blueberries, raspberries, or a mix of all three add a fresh contrast to the rich casserole.

• Maple syrup: A generous drizzle of warm maple syrup is always a good idea and brings out all those cozy breakfast flavors.

• Crispy bacon: The salty crunch of bacon works really well with the sweet cinnamon flavors.

• Breakfast sausage: Sausage links or patties help turn this into a more filling breakfast or brunch spread.

• Whipped cream: Perfect for special occasions when you want breakfast to feel a little more indulgent.

• Fresh fruit salad: A simple bowl of fruit helps balance the richness and adds plenty of color to the table.

• Greek yogurt: A spoonful on the side adds a creamy, slightly tangy contrast to the sweetness.

• Powdered sugar: A light dusting over the top makes the casserole look extra inviting with very little effort.

• Chopped pecans or walnuts: Sprinkle a handful on top just before serving for a little crunch.

• Hot coffee or tea: The perfect way to round out a cozy breakfast, especially on chilly mornings.

Storing

• Refrigerate leftovers: Store any leftover French toast casserole in an airtight container in the refrigerator for up to 3 days.

• Reheat individual portions: Pop a serving in the microwave for 30 to 60 seconds, or until heated through.

• Reheat larger portions: Cover with foil and warm in a 350°F oven until hot in the center.

• Freeze for later: Once completely cooled, place portions in freezer-safe containers or bags and freeze for up to 2 months.

• Thaw overnight: Transfer frozen portions to the refrigerator the night before you plan to eat them for the best texture.

• Add toppings after reheating: Maple syrup, powdered sugar, whipped cream, and fresh fruit are best added just before serving.

• Keep it covered: This helps prevent the casserole from drying out and keeps it tasting fresh.

Variations & Substitutions

• Use brioche or challah: Both breads make a richer casserole and soak up the custard beautifully.

• Add fresh berries: Blueberries, raspberries, or diced strawberries can be mixed in with the bread before cooking.

• Try sliced bananas: Bananas add extra sweetness and pair perfectly with the cinnamon flavors.

• Mix in chocolate chips: A handful of chocolate chips turns this into a fun breakfast treat that kids especially love.

• Add nuts for crunch: Chopped pecans or walnuts add texture and a little extra flavor.

• Swap the spices: Try adding a pinch of pumpkin pie spice or apple pie spice for a seasonal twist.

• Use half-and-half instead of heavy cream: If that’s what you have on hand, it will still give you a rich, creamy custard.

• Make it extra indulgent: Stir a few ounces of softened cream cheese into the bread mixture before cooking.

• Add diced apples: Fresh apples work really well and give the casserole an apple-cinnamon flavor.

• Reduce the sweetness: Cut back slightly on the sugar if you prefer a less sweet breakfast and plan to serve it with syrup.

• Use a different topping: Try chopped nuts, a streusel topping, or even a handful of shredded coconut before cooking.

• Add raisins or dried cranberries: These bring a little chewiness and extra sweetness to every bite.
