What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, with fresh berries adding a seasonal pop of color and taste:

• Bread: 1 loaf of thick-cut brioche or challah, cubed (about 10 cups). I prefer Pepperidge Farm brioche for the perfect buttery texture.
• Eggs: 8 large eggs, room temperature (adds richness and structure).
• Milk: 2 cups (480 ml) whole milk or half-and-half for extra creaminess (use dairy-free milk if needed).
• Granulated Sugar: 1/2 cup (100 g) for a touch of sweetness.
• Vanilla Extract: 2 teaspoons, pure (the secret to that warm, inviting aroma).
• Cinnamon: 1 teaspoon ground (for that classic French toast flavor).
• Salt: 1/4 teaspoon (balances the sweetness).
• Butter: 2 tablespoons, melted (adds moistness and flavor).
• Fresh Berries: 2 cups mixed berries (strawberries, blueberries, raspberries). In summer, swap in fresh berries; frozen works fine year-round.
• Powdered Sugar: For dusting before serving (optional, but highly recommended for presentation).

Substitutions: Use almond or oat milk to keep it dairy-free. For a gluten-free twist, swap the bread for a gluten-free loaf, though the texture will differ slightly. If you want it a bit lighter, half the sugar does the trick without sacrificing flavor. I’ve found that fresh berries really brighten this dish, but you can swap for frozen if fresh aren’t available—just thaw and drain excess liquid before assembling.

Equipment Needed

• 9×13-inch Baking Dish: A standard glass or ceramic casserole dish works best to hold everything together.
• Mixing Bowls: One large for whisking the custard, plus a smaller one for prepping berries if needed.
• Whisk: Essential for blending eggs, milk, and spices smoothly.
• Measuring Cups and Spoons: Accuracy counts here for custard consistency.
• Spatula: For folding bread cubes into the custard without squishing them.

If you don’t have a 9×13-inch dish, a similar-sized oven-safe pan will do; just adjust baking time slightly. I’ve also used disposable aluminum trays when gifting this casserole, which is a budget-friendly option and saves cleanup. Pro tip: lightly butter or spray your baking dish to prevent sticking, especially if you’re using a glass pan.

Preparation Method

1. Cube the Bread: Cut your brioche or challah loaf into roughly 1-inch (2.5 cm) cubes, aiming for about 10 cups. Toss them gently into your baking dish, spreading evenly. This step takes about 5 minutes.
2. Mix the Custard: In a large bowl, whisk together 8 large eggs, 2 cups (480 ml) whole milk or half-and-half, 1/2 cup (100 g) granulated sugar, 2 teaspoons vanilla extract, 1 teaspoon ground cinnamon, 1/4 teaspoon salt, and 2 tablespoons melted butter. Whisk until smooth and slightly frothy—this takes about 3 minutes. If you see any egg whites clumping, give it a few more whisks for even blending.
3. Soak the Bread: Pour the custard evenly over the bread cubes, pressing down gently with your spatula or hands to help the bread absorb the liquid. Let it sit for at least 30 minutes at room temperature, or better yet, cover and refrigerate overnight (8-12 hours) for a custardy magic moment.
4. Add the Berries: Just before baking, scatter 2 cups of fresh mixed berries evenly over the top of the soaked bread. This keeps them fresh and juicy after baking.
5. Bake: Preheat your oven to 350°F (175°C). Place the baking dish in the oven and bake uncovered for 45-55 minutes, or until the top is golden brown and a knife inserted in the center comes out clean. If the top browns too quickly, loosely tent with foil during the last 10 minutes.
6. Cool & Serve: Remove from oven and let the casserole cool for 10 minutes. Dust with powdered sugar if you like, slice into squares, and serve warm with maple syrup or a dollop of whipped cream.

Tips: If your bread looks soggy after soaking, that’s a good sign—it means it’s absorbing all that delicious custard. For a crisper top, you can broil the last 2-3 minutes, but watch closely to avoid burning. And trust me, letting it rest a bit before serving helps everything set nicely and makes slicing easier.

Cooking Tips & Techniques

Here’s what I’ve learned from countless batches of this French toast casserole:

• Use Day-Old Bread: Slightly stale bread soaks up custard better without falling apart. If your bread is fresh, you can toast it lightly first.
• Room Temperature Eggs: Cold eggs can cause custard to separate. Let them sit out for 15 minutes before mixing.
• Don’t Overmix: Whisk eggs and milk just until combined to keep custard smooth but not overly frothy.
• Overnight Soaking: This step is key. It lets the bread fully absorb flavors and results in a custard that’s creamy inside and slightly crisp on top.
• Watch Your Oven: Oven temperatures vary, so start checking doneness at 40 minutes. The center should be set but not dry.
• Multi-task: While soaking, prep your toppings or set the table to save time.
• Don’t Skip the Butter: It adds richness and helps prevent dryness.

One time, I forgot to let it soak overnight, and while still tasty, the texture was less custardy and more bread pudding-like. Lesson learned—patience pays off here!

Variations & Adaptations

This easy French toast casserole with fresh berries is flexible—you can easily tweak it to suit your taste or dietary needs:

• Vegan Version: Swap eggs for a flaxseed egg mix (2 tablespoons ground flaxseed + 6 tablespoons water), use almond or oat milk, and dairy-free butter. Adjust baking time slightly as custard sets differently.
• Seasonal Fruit Swap: In fall, try diced apples and a sprinkle of nutmeg instead of berries. In winter, pomegranate seeds add a festive touch.
• Gluten-Free: Use gluten-free bread (I recommend a sturdy sourdough-style loaf) and double-check all other ingredients.
• Sweet & Savory: Add a handful of chopped nuts for crunch or a drizzle of honey and a pinch of sea salt on top before baking for a sweet-salty twist.
• Personal Favorite: I once added a swirl of cream cheese and raspberry jam in the middle before baking for a luscious surprise—totally worth trying!

Serving & Storage Suggestions

Serve this casserole warm for the best experience. A dusting of powdered sugar and a drizzle of warm maple syrup make it feel extra special. It pairs beautifully with crispy bacon or sausage and a hot cup of coffee or fresh orange juice.

If you have leftovers (which might be rare!), cover and refrigerate for up to 3 days. To reheat, pop individual portions in the microwave for 30-45 seconds or warm in a 325°F (160°C) oven for about 10 minutes, covered with foil to prevent drying out.

For longer storage, freeze the casserole before baking in an airtight container for up to 2 months. Bake from frozen, adding 10-15 minutes to the cooking time. Flavors actually deepen after resting, so leftovers taste even better the next day.
