Step‑by‑Step Instructions for Overnight French Toast Casserole
Step 1: Prepare Bread
Begin by spreading your cubed day-old bread evenly on a cookie sheet. Allow the bread to dry out for about 1 hour at room temperature, which helps strengthen the texture and ensures it absorbs the custard mixture beautifully during soaking.
Step 2: Mix Custard
In a large mixing bowl, whisk together the eggs, whole milk, salt, granulated sugar, vanilla extract, cinnamon, and nutmeg until the mixture is smooth and well combined. This creamy custard is essential for the Overnight French Toast casserole, giving it that rich and decadent flavor everyone loves.
Step 3: Layer Bread and Meat
Grease a 9″ x 13″ baking dish and start layering by placing half of the dried bread cubes in a single layer on the bottom. If you’re opting for the added savory twist, scatter cooked and crumbled bacon or diced sausage over this layer before adding the remaining bread cubes for extra depth of flavor.
Step 4: Soak Bread
Carefully pour the rich custard mixture evenly over the layered bread. Gently press down on the bread cubes with a spatula or your hands to ensure all pieces are submerged in the custard. This soaking step is crucial for achieving that soft, custardy interior.
Step 5: Chill
Cover the baking dish tightly with plastic wrap and place it in the refrigerator. Allow the casserole to chill for several hours, or ideally overnight, so the bread absorbs all the flavors from the custard mixture, creating a deeply satisfying breakfast.
Step 6: Bake
Preheat your oven to 350°F (175°C). Sprinkle cinnamon sugar on top if you desire a sweet, crunchy topping. Place the casserole in the oven and bake for 60 to 70 minutes, or until the top is lightly browned and a toothpick inserted in the center comes out clean, indicating it has set perfectly.
Step 7: Serve
Once baked, remove the Overnight French Toast casserole from the oven and let it cool for a few minutes. Slice into squares and serve warm, drizzling with maple syrup if desired. Each bite offers that comforting essence of classic French toast, making it a delightful treat for any breakfast table.

Expert Tips for the Best Overnight French Toast

Cover While Soaking: Tightly wrap the casserole in plastic wrap to prevent the bread from drying out while it soaks in the custard overnight.
Check for Doneness: Insert a toothpick into the center while baking; it should come out clean for a perfectly set Overnight French Toast.
Allow to Cool: Let the casserole cool slightly after baking before cutting to maintain its shape and presentation.
Personalize Your Flavors: Feel free to experiment with spices and add-ins—such as berries or chocolate—to make this dish your own!
Make Ahead Options
Preparing Overnight French Toast in advance is a genius way to simplify your busy mornings! You can layer the bread and custard mixture and refrigerate it up to 24 hours before baking. Simply follow the steps up to the chilling stage, cover it tightly, and let it soak in the rich flavors overnight. This not only enhances the taste but also ensures your casserole has the perfect custardy texture. If you need to prep further in advance, consider making the cinnamon sugar and cooking the bacon or sausage up to 3 days prior; just store them in separate airtight containers in the fridge. When you’re ready to enjoy this delightful breakfast, preheat your oven and bake it straight from the fridge for fantastic results, saving you precious time on busy mornings!
Overnight French Toast Casserole Recipe FAQs
How do I select the best bread for my casserole?
Choosing the right bread is key for achieving the perfect custard texture. I recommend using day-old bread, as it has dried out slightly, allowing it to absorb the custard beautifully without becoming mushy. Options like French bread, challah, or brioche work wonderfully, enhancing the flavor and richness of your Overnight French Toast casserole.
What’s the best way to store leftovers?
Absolutely! Store any leftovers in an airtight container in the fridge for up to 3 days. When you’re ready to enjoy it again, simply reheat in the microwave or oven until warmed through. This makes for a quick and delicious breakfast option on busy mornings!
Can I freeze Overnight French Toast casserole? How?
Yes, you can freeze it! Wrap portions of your Overnight French Toast casserole tightly in plastic wrap followed by aluminum foil; this will help prevent freezer burn. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy, thaw it overnight in the fridge, then reheat in the oven at 350°F (175°C) for about 20-25 minutes, or until heated through.
What should I do if my casserole is soggy?
If you find that your Overnight French Toast casserole turns out soggy, it might be due to using fresh bread rather than stale bread, or not allowing enough soaking time. Make sure you use stale bread for better absorption and give it a good soak in the custard. To remedy a soggy casserole, you can bake it a bit longer to help evaporate excess moisture, but be careful not to overbake it.

Great question! For those with dietary restrictions, there are several adjustments you can make. You can use non-dairy milk and egg alternatives to adapt this recipe for a dairy-free or vegan option.

Always make sure guests are aware of any ingredients that may trigger allergies!
