Ingredients You’ll Need
To make the perfect Overnight Brioche French Toast, you need quality ingredients. We recommend visiting a local bakery for the bread if possible. High-quality dairy also makes a significant difference in the final custard consistency. Here is exactly what you need to gather for your Overnight Brioche French Toast.

| Ingredient | Quantity | Notes |
|---|---|---|
| Brioche Bread | 1 large loaf (14-16 oz) | Cut into 1-inch thick slices or cubes. |
| Large Eggs | 8 units | Use room temperature eggs for better mixing. |
| Whole Milk | 2 cups | Full fat provides the best richness. |
| Heavy Cream | 1 cup | Adds a luxurious, velvety texture. |
| Brown Sugar | 1/2 cup | Packed. Light or dark both work well. |
| Vanilla Extract | 1 tablespoon | Pure vanilla provides the best flavor. |
| Ground Cinnamon | 1 teaspoon | Adds warmth and classic spice. |
| Ground Nutmeg | 1/4 teaspoon | A little goes a long way for depth. |
| Salt | 1/4 teaspoon | Balances the sweetness perfectly. |
| Unsalted Butter | 2 tablespoons | For greasing the baking dish. |
Substitutions & Variations
You can easily customize your Overnight Brioche French Toast based on what you have in the pantry. If you cannot find brioche, Challah bread serves as an excellent substitute. Both breads share a high egg and butter content, which is vital for this dish.
For a dairy-free Overnight Brioche French Toast, use full-fat coconut milk and a splash of almond milk. You should avoid thin, white sandwich bread, as it will likely disintegrate during the soak. For a flavor twist, add the zest of one orange to the custard.
Henry often adds a handful of pecans or walnuts on top for a delightful crunch. If you prefer fruit, scatter fresh blueberries or raspberries between the bread layers before pouring the liquid. You can also swap the brown sugar for maple syrup or honey if you prefer natural sweeteners.
Some people even add a splash of bourbon or rum to the custard for a more “grown-up” version of Overnight Brioche French Toast. Regardless of the changes, keep the egg-to-liquid ratio consistent to ensure the dish sets properly.
Step-by-Step Instructions
Preparing this Overnight Brioche French Toast requires only about fifteen minutes of active work. Follow these steps carefully to ensure your breakfast turns out perfectly golden and delicious. Henry always says that patience is the most important ingredient here.
- Prepare the Pan: Generously grease a 9×13-inch baking dish with softened butter. Ensure you coat the corners well to prevent sticking.
- Slice the Bread: Cut your brioche loaf into thick slices, about one inch each. Alternatively, you can cut the bread into one-inch cubes for a more rustic look. Arrange the bread in the prepared dish. If using slices, overlap them slightly to fit.
- Mix the Custard: In a large mixing bowl, crack the eight eggs. Whisk them thoroughly until no streaks of white remain. Add the whole milk, heavy cream, brown sugar, vanilla extract, cinnamon, nutmeg, and salt. Whisk vigorously until the sugar dissolves and the spices distribute evenly.
- Pour and Soak: Slowly pour the custard mixture over the bread. Ensure every piece of bread gets at least a little liquid. Press down gently on the bread with your hands or a spatula to help it submerge.
- Chill: Cover the dish tightly with plastic wrap or aluminum foil. Place it in the refrigerator for at least six hours, though overnight is much better. This long soak allows the Overnight Brioche French Toast to develop its signature texture.
- Bake: The next morning, remove the dish from the fridge. Let it sit on the counter for 20 minutes to take the chill off. Preheat your oven to 350°F (175°C). Remove the plastic wrap and bake for 45 to 50 minutes.
- Check for Doneness: The Overnight Brioche French Toast should be puffed, golden brown, and set in the center. If you shake the pan, the middle should not jiggle like liquid.
- Rest and Serve: Let the dish rest for 5 to 10 minutes before slicing. This allows the custard to firm up slightly. Serve warm with your favorite toppings.

Pro Tips for Success
To achieve the best results with your Overnight Brioche French Toast, use stale bread. Fresh bread contains too much moisture and might become mushy. If your bread is fresh, slice it and leave it on the counter for a few hours.
Alternatively, toast the slices lightly in a low oven for ten minutes. Another tip involves the custard distribution. Halfway through the soaking time, if you are still awake, you can gently flip the bread slices.
This ensures the top side gets just as much flavor as the bottom. Furthermore, do not skip the heavy cream. While you might feel tempted to use only milk, the cream provides the necessary fat for a custard-like finish.
When baking the Overnight Brioche French Toast, if the top browns too quickly, cover it loosely with foil. This allows the center to finish cooking without burning the edges. Always use a high-quality vanilla extract, as the flavor really shines through in this simple dish.
Finally, make sure your baking dish is the right size. If the dish is too large, the custard will spread too thin and the bread won’t soak properly. Following these tips will ensure your Overnight Brioche French Toast earns rave reviews every time.

Storage & Reheating Tips
If you happen to have leftovers of this Overnight Brioche French Toast, do not let them go to waste. You can store cooked portions in an airtight container in the refrigerator for up to three days. To maintain the best texture, avoid the microwave for reheating if possible.
Instead, place a slice in a toaster oven or the main oven at 350°F until warmed through. This helps crisp up the exterior again. You can also freeze cooked Overnight Brioche French Toast.
Wrap individual slices in parchment paper and place them in a freezer bag. They will stay fresh for up to two months. When you feel a craving, simply thaw a slice in the fridge overnight and reheat it in the oven.
This makes for a very quick weekday breakfast. Henry often makes a double batch of Overnight Brioche French Toast just so he has easy meals for the rest of the week. Always ensure the dish has cooled completely before you seal it for storage to prevent condensation from making the bread soggy.
What to Serve With This Recipe
This Overnight Brioche French Toast is quite rich, so balance is key when choosing side dishes. We love serving it with crispy, salty bacon or savory breakfast sausage links. The saltiness cuts through the sweetness of the maple syrup beautifully.
Fresh fruit also makes an excellent companion. A simple bowl of macerated strawberries or tart Granny Smith apple slices works wonders. For a more indulgent brunch, offer a dollop of Greek yogurt or lightly sweetened whipped cream.
If you want to impress guests, serve this Overnight Brioche French Toast alongside a vibrant citrus salad with mint. As for drinks, a strong pot of black coffee is essential. Henry prefers a cold glass of orange juice, while I think a sparkling mimosa pairs perfectly with the buttery brioche.
You can also set up a topping bar. Include items like toasted coconut, sliced almonds, mini chocolate chips, and different fruit compotes. This allows everyone to customize their Overnight Brioche French Toast to their own liking.

FAQs
Can I use regular white bread instead of brioche?
You can use regular white bread, but the results will differ significantly. Standard sandwich bread is much thinner and less sturdy. Consequently, it may become very soggy after soaking overnight.
If you must use it, do not soak it for more than two hours. We strongly recommend using brioche or Challah for the best Overnight Brioche French Toast experience, as these breads hold their structure much better.
How long does the bread need to soak?
For the best results, you should let your Overnight Brioche French Toast soak for at least six to eight hours. This duration allows the custard to penetrate to the very center of the thick brioche slices. If you are in a rush, you can bake it after two hours, but the texture will be less uniform. The “overnight” aspect is truly what makes this dish special and convenient for morning hosting.
Can I freeze the Overnight Brioche French Toast before baking?
We do not recommend freezing the unbaked Overnight Brioche French Toast. The freezing and thawing process can break down the custard and make the bread unpleasantly mushy. However, you can certainly freeze the dish after it has been baked and cooled. This preserves the texture and allows for a much better reheating experience later on.
Why is my French toast soggy in the middle?
If your Overnight Brioche French Toast comes out soggy, it usually means one of two things. Either the oven temperature was too high, causing the outside to brown before the inside set, or you did not bake it long enough. Every oven varies, so always use the “jiggle test.” If the center still moves like liquid, it needs more time. Also, using fresh bread instead of stale bread contributes to excess moisture.
Do I have to bake the French toast covered?
You do not need to bake this Overnight Brioche French Toast covered for the entire time. In fact, baking it uncovered allows the top to become beautifully golden and crisp. However, if you notice the bread browning too quickly after thirty minutes, you can loosely place a piece of foil over the top. This protects the surface while the internal custard finishes cooking through.
