6 cups day-old bread cubes (I use thick-cut brioche or challah for rich custard soaked bread)
4 large eggs
2 cups whole milk (No worries if you don’t have whole milk—I often swap with almond or oat milk in my French Toast Casserole)
1/2 cup granulated sugar
1 tablespoon vanilla extract (You’ll find this in the baking aisle, and it’s key for a great flavor boost)
1 teaspoon ground cinnamon (This keeps the cinnamon vanilla syrup notes balanced)
1/4 teaspoon salt
2 tablespoons melted butter (Plus some extra for greasing the baking dish)
Powdered sugar and maple syrup for serving

You can easily adjust bread types based on what’s on hand—day-old sandwich bread works fine, but the thicker, denser breads soak up the custard better and yield a creamier baked French toast.

This French Toast Casserole stays budget-friendly since it uses common pantry staples. I like to prep the bread cubes the day before and store them in an airtight container, so they’re ready to toss with the custard. Leftovers? They keep well in the fridge for up to 3 days and reheat nicely in the oven or microwave.

If you want a little extra, I sometimes sprinkle in a handful of chopped pecans or berries before baking—not necessary, but a personal favorite touch that adds texture and freshness.

1. Prep your baking dish: Butter a 9×13-inch casserole dish. This will keep your French Toast Casserole from sticking and add a little buttery flavor around the edges.

2. Mix the custard: In a large bowl, whisk together eggs, milk, sugar, vanilla extract, cinnamon, and salt until smooth. This custard mixture is what transforms the bread into a soft, decadent baked French toast.

3. Add the bread: Toss in the bread cubes and gently mix so each piece gets coated in the custard. Make sure the bread is well soaked—the secret to that melt-in-your-mouth texture.

4. Let it soak: Cover the dish with plastic wrap or a lid and refrigerate for at least 2 hours or overnight. This step is crucial for the custard soaked bread to absorb all those wonderful flavors.

5. Preheat your oven: Set it to 350°F (175°C) about 20 minutes before baking.

6. Bake your casserole: Take the dish out of the fridge, remove the cover, and pour melted butter over the top. Bake uncovered for 45 to 50 minutes, until the top is golden brown and the custard feels set.

7. Serving time: Your kitchen will smell amazing with the cinnamon and vanilla scents warming the air. Let the French Toast Casserole cool for a few minutes before slicing. Dust with powdered sugar and drizzle with maple syrup or cinnamon vanilla syrup for that extra special touch.

From start to finish, this French Toast Casserole takes about an hour (with that crucial soaking time). While it’s baking, I like to set the table or prepare a fresh fruit salad for a balanced brunch spread.

A quick tip: Don’t worry if the edges look extra crisp—that’s part of the charm. The center should be soft and custardy but fully cooked. And if you’re short on time, you can do a minimum 2-hour soak instead of overnight and still get great results.

This recipe is a keeper in my home, and I’ve found making the custard mixture just right is key. I used to rush this step and ended up with uneven custard soaked bread. Taking your time here really pays off.

This French Toast Casserole is delicious served warm with a drizzle of maple syrup or cinnamon vanilla syrup, which adds a sweet, spiced depth that makes breakfast feel special.

I often pair it with fresh fruit like berries or a simple side of scrambled eggs and crispy bacon for a balanced meal. For a more filling brunch casserole recipe, I sometimes add sausage links on the side. The combination of sweet and savory hits every comfort note you want.

Presentation-wise, dusting the top with powdered sugar right before serving adds a nice touch, and a few mint leaves or fruit on the side brighten the plate. It’s perfect for weekend breakfasts, holiday mornings, or even casual dinners when you want a crowd-pleaser that’s both hearty and homemade.

One of my favorite leftover ideas is to cut the casserole into small squares and toast them lightly the next day for a quick grab-and-go morning treat. Leftovers also freeze well if you portion them out before reheating.

Seasonally, I’ve tried adding pumpkin puree and nutmeg for a fall-inspired twist—kind of like the Pumpkin Spice French Toast Casserole you might want to explore once you fall in love with this one.

Can I make this French Toast Casserole ahead of time?
Absolutely! This overnight breakfast bake is meant to be assembled the night before and baked fresh in the morning. It saves lots of time and helps flavors develop. If you’re short on time, 2 hours of soaking still works.

What’s a good substitute for whole milk?
I often swap in almond or oat milk without any trouble. Just avoid anything too watery or flavored varieties, which might affect taste.

How do I adjust for more or fewer people?
Simply scale the ingredients up or down depending on your crowd. The 9×13-inch dish fits about 6-8 servings comfortably. For smaller portions, use an 8×8 dish and reduce baking time slightly.

Can I add fruit to my French Toast Casserole?
Yes! Fresh or frozen berries, sliced apples, or peaches work well. Stir them in with the bread or sprinkle on top before baking for a natural sweetness.

Is day-old bread necessary?
Using day-old or slightly stale bread is best because it soaks up the custard without falling apart. If your bread is fresh, dry it out in a low oven for 10 minutes.

Can I make this gluten-free?
Yes! Gluten-free bread works just fine. Just make sure it’s sturdy enough to hold up to soaking.

What about adding nuts or extra flavorings?
I like to toss in chopped pecans or walnuts for crunch. A pinch of nutmeg or orange zest can also add a nice twist. It’s easy to customize.
