Ingredients Breakdown
Creating the perfect French Toast Casserole is all about understanding how each ingredient contributes to that ideal texture and rich, comforting flavor we’re after. Let’s explore what makes this dish so incredibly satisfying.
For the Bread Base:
- 1 large loaf (about 1 pound) day-old French bread or brioche – The foundation of our casserole. Day-old bread is crucial because it absorbs the custard mixture perfectly without falling apart. Brioche adds extra richness, but French bread works wonderfully too.
- Butter for greasing – Prevents sticking and adds extra richness to the bottom and sides.
For the Custard Mixture:
- 8 large eggs – Creates the custardy base that transforms ordinary bread into something magical. Room temperature eggs blend more easily.
- 2 cups whole milk – Provides creaminess and helps create that perfect custard texture. Don’t use skim milk as it won’t give you the rich results you want.
- 1/2 cup heavy cream – Takes the richness up a notch and creates an extra silky texture.
- 3/4 cup granulated sugar – Sweetens the custard and helps create caramelization on top during baking.
- 1 tablespoon vanilla extract – Essential for that warm, comforting flavor that makes French toast so special.
- 1 teaspoon ground cinnamon – Adds warmth and that classic French toast spice.
- 1/4 teaspoon ground nutmeg – A subtle spice that enhances the overall flavor complexity.
- 1/4 teaspoon salt – Balances the sweetness and enhances all other flavors.
For the Crunchy Topping (Optional but Recommended):
- 1/2 cup all-purpose flour – Creates texture contrast with the soft custard.
- 1/2 cup packed brown sugar – Adds molasses notes and helps create caramelization.
- 1/2 teaspoon cinnamon – Extra spice for the topping layer.
- 1/4 teaspoon salt – Balances the sweetness.
- 6 tablespoons cold butter, cubed – Creates a streusel-like topping that bakes to golden perfection.
Common Substitutions:
- Bread alternatives: Challah, Texas toast, croissants, or even leftover donuts work beautifully
- Dairy-free option: Use coconut milk and coconut cream instead of dairy milk and cream
- Lower sugar version: Reduce sugar by 1/4 cup and add a sugar substitute if desired
- Egg substitute: Use 2 cups of egg substitute for the whole eggs if needed
- Spice variations: Try cardamom, allspice, or pumpkin pie spice instead of traditional cinnamon and nutmeg
Step-by-Step Instructions
Step 1: Prepare Your Bread and Pan
Start by cutting your day-old bread into 1-inch thick slices, then cube them into bite-sized pieces. You want pieces that are substantial enough to hold their shape but not so large that they don’t soak up the custard properly. Generously butter a 9×13 inch baking dish, making sure to get the corners and sides well-coated.
Arrange the bread cubes in the prepared dish in an even layer. Don’t pack them too tightly – you want the custard mixture to flow around and between the pieces. If using particularly dense bread, you can lightly toast the cubes for 5-10 minutes in a 350°F oven before proceeding.
Step 2: Create the Perfect Custard
In a large mixing bowl, whisk the eggs thoroughly until they’re well beaten and slightly frothy. This ensures a smooth custard without any streaks of egg white. Gradually add the milk and heavy cream, whisking constantly to prevent the eggs from cooking.
Add the granulated sugar, vanilla extract, cinnamon, nutmeg, and salt. Whisk everything together until the sugar is completely dissolved and the mixture is smooth and well combined. The custard should have a lovely golden color and smell absolutely divine.
Step 3: Soak the Bread
Pour the custard mixture evenly over the arranged bread cubes, making sure every piece gets coated. Use a spoon or spatula to gently press the bread down into the custard, ensuring it’s all well-soaked. Some pieces will float initially, but they’ll absorb the liquid as they sit.
Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours, but preferably overnight. This resting time is crucial – it allows the bread to fully absorb the custard, creating that perfect creamy interior we’re after.
Step 4: Prepare the Streusel Topping
About 30 minutes before you’re ready to bake, remove the casserole from the refrigerator to come closer to room temperature. Meanwhile, prepare your streusel topping by combining the flour, brown sugar, cinnamon, and salt in a medium bowl.
Add the cold, cubed butter and use your fingers or a pastry cutter to work it into the dry ingredients until the mixture resembles coarse crumbs with some larger butter pieces. These butter pieces will create lovely pockets of richness as they melt during baking.
Step 5: Bake to Golden Perfection
Preheat your oven to 350°F (175°C). Remove the plastic wrap from the casserole and sprinkle the streusel topping evenly over the surface. Don’t worry about covering every inch – some variation adds visual interest and texture contrast.
Bake for 45-55 minutes, until the top is golden brown and set, and a knife inserted in the center comes out mostly clean with just a few moist crumbs. The casserole should be puffed up and smell absolutely incredible. If the top browns too quickly, cover loosely with foil.
Step 6: Rest and Serve
Let the casserole rest for 10-15 minutes before serving. This allows it to set up properly and makes it easier to cut clean slices. The internal temperature should reach 160°F for food safety. Serve warm with your favorite toppings and watch everyone’s faces light up with that first bite.
Tips and Variations
Expert Tips for Perfect Results:
- Use day-old bread that’s slightly stale – it absorbs custard better without becoming mushy
- Don’t skip the overnight soaking time; it’s essential for proper texture
- Cover with foil if the top browns too quickly during baking
- Let it rest before serving to allow proper setting
- Make sure your custard mixture is well-combined with no streaks of egg
Delicious Variations to Try:
- Berry Bliss: Add 1 1/2 cups mixed fresh or frozen berries between the bread layers
- Apple Cinnamon: Layer thin apple slices with extra cinnamon throughout
- Chocolate Chip Delight: Sprinkle mini chocolate chips between the bread pieces
- Orange Cream: Add orange zest to the custard and top with orange glaze
- Pumpkin Spice: Replace some milk with pumpkin puree and add pumpkin pie spice

Storage and Reheating Instructions
Overnight Preparation: The beauty of this casserole lies in its make-ahead convenience. Assemble the entire casserole up to 24 hours before baking, cover tightly with plastic wrap, and refrigerate. Just add the streusel topping and bake when ready to serve. This makes it perfect for holiday mornings or when entertaining guests.
Leftover Storage: Store leftover casserole covered in the refrigerator for up to 4 days. The flavors actually develop and improve over the first day or two, making leftovers almost as good as the fresh-baked version. Cover tightly with plastic wrap or transfer to an airtight container.
Reheating Instructions: For best results, reheat individual portions in the microwave for 60-90 seconds, or warm the entire dish covered with foil in a 325°F oven for 15-20 minutes. You can also reheat individual slices in a toaster oven for a slightly crispy exterior.
Freezing Options: This casserole freezes wonderfully either before or after baking. To freeze unbaked, assemble completely, wrap tightly, and freeze for up to 3 months. Thaw overnight in refrigerator before baking, adding 10-15 minutes to the baking time. Baked casserole can be frozen in portions for up to 2 months.
Recipe Notes
Bread Selection Tips: The type of bread you choose dramatically affects the final texture. Brioche creates the richest, most luxurious result, while French bread offers a more traditional texture. Avoid thin-sliced sandwich bread as it can become too soggy.
Timing for Success: This recipe requires planning ahead, but the actual hands-on time is minimal. Assemble the night before, then just add topping and bake in the morning. It’s perfect for stress-free entertaining.
Texture Preferences: If you prefer a more bread pudding-like texture, soak for longer and press the bread down more firmly. For more distinct bread pieces, use a lighter touch and shorter soaking time.
Size Adjustments: This recipe easily doubles for larger crowds – just use a larger dish or two 9×13 pans. For smaller families, halve the recipe and use a 9×9 inch dish, reducing baking time to 35-40 minutes.
Quality Ingredients Matter: Use real vanilla extract, fresh eggs, and good-quality bread for the best results. The simple ingredient list means each component really shines through in the final dish.

Frequently Asked Questions
1. Can I use fresh bread instead of day-old bread? While day-old bread works best because it absorbs the custard better, you can use fresh bread in a pinch. Just toast the cubes lightly in a 350°F oven for 10-15 minutes to remove some moisture before proceeding with the recipe.
2. How far in advance can I prepare this casserole? You can assemble the entire casserole (minus the streusel topping) up to 24 hours before baking. Add the topping right before baking for the best texture. This makes it perfect for holiday mornings or entertaining.
3. What should I do if my casserole seems too wet after baking? If the center seems too wet, continue baking in 5-minute increments until a knife inserted in the center comes out mostly clean. Some moisture is normal and desirable, but it shouldn’t be soupy. Make sure you’re using day-old bread for better absorption.
4. Can I make individual portions instead of one large casserole? Absolutely! Divide the bread and custard mixture among 8-10 individual ramekins or small baking dishes. Reduce the baking time to 25-30 minutes. This presentation is perfect for elegant brunches or when you want portion control.
5. Is it normal for the casserole to puff up during baking? Yes! The eggs in the custard mixture cause the casserole to puff up beautifully during baking, similar to a soufflé. It will settle slightly as it cools, which is completely normal. This puffing is actually a sign that your custard mixture was well-prepared.
