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, and the berries add a seasonal touch you can swap out depending on what’s fresh or frozen.

• Bread: 1 loaf (about 12 oz / 340 g) of sturdy bread like brioche, challah, or thick-cut French bread (day-old works best for soaking)
• Milk: 2 cups (480 ml) whole milk or any milk of your choice (I like using 2% for creaminess)
• Heavy Cream: 1/2 cup (120 ml) for that luscious custard texture
• Eggs: 6 large eggs, room temperature (helps everything bind beautifully)
• Cream Cheese: 4 oz (115 g), softened (adds richness and a silky custard feel)
• Sugar: 1/2 cup (100 g) granulated sugar (you can substitute with coconut sugar or maple syrup for a different spin)
• Vanilla Extract: 2 teaspoons (for that warm, inviting aroma)
• Cinnamon: 1 teaspoon ground cinnamon (the classic French toast spice)
• Salt: 1/4 teaspoon (balances the sweetness)
• Mixed Berries: 1 1/2 cups (225 g) fresh or frozen blueberries, raspberries, or blackberries (in summer, swap in fresh berries; frozen works fine too)
• Optional Toppings: Maple syrup, powdered sugar, or chopped nuts for serving

Tip: I recommend using a sturdy bread like brioche or challah because it soaks up the custard without falling apart. For the berries, fresh ones give you a nice bite, but frozen berries are a convenient year-round option.

Equipment Needed

• A 9×13-inch (23×33 cm) baking dish — glass or ceramic works best for even baking and easy cleanup
• Mixing bowls — one large bowl for custard, another for cream cheese blending
• Electric mixer or whisk — an electric hand mixer makes softening cream cheese and blending the custard effortless, but a sturdy whisk works too
• Measuring cups and spoons — for precise ingredients
• Rubber spatula — to fold berries gently without breaking them
• Optional: Plastic wrap or aluminum foil to cover the dish overnight

Honestly, if you don’t have a mixer, no worries — it just takes a bit more elbow grease. I’ve also used disposable foil pans when sharing this at potlucks, which is a budget-friendly option and perfect for gifting.

Preparation Method

1. Prepare the Bread (10 minutes): Cut your loaf into 1-inch (2.5 cm) cubes. If your bread is fresh, toast the cubes lightly in the oven at 325°F (160°C) for 10 minutes to dry them out a bit — this prevents sogginess. Let cool.
2. Mix the Cream Cheese Custard (5 minutes): In a large bowl, soften the cream cheese using an electric mixer or whisk until smooth. Add the eggs, sugar, vanilla extract, cinnamon, and salt. Beat until fully combined.
3. Add Milk and Cream (2 minutes): Slowly pour in the milk and heavy cream, mixing until the custard is silky and smooth with no lumps.
4. Combine Bread and Berries (3 minutes): Place the bread cubes in your baking dish and sprinkle the mixed berries evenly over the top. Gently fold the berries into the bread with a spatula — try not to smash them!
5. Pour Custard Over (2 minutes): Pour the custard mixture evenly over the bread and berries, pressing down lightly so the bread soaks up the liquid. Cover with plastic wrap or foil.
6. Refrigerate Overnight (8-12 hours): Pop the covered dish into the fridge and let the bread soak overnight. This step is crucial for the custard to fully absorb and flavor to meld.
7. Bake the Casserole (45-50 minutes): Preheat your oven to 350°F (175°C). Remove the plastic wrap or foil and bake uncovered until the top is golden brown and the custard is set (a knife inserted should come out clean). If the top browns too quickly, tent with foil halfway through.
8. Cool and Serve (10 minutes): Let the casserole cool slightly before serving. It’s heavenly topped with a dusting of powdered sugar and a drizzle of maple syrup.

Note: If you notice the custard hasn’t fully absorbed in the morning, gently press the bread cubes down again before baking to ensure even soaking. The casserole should smell fragrant with cinnamon and vanilla when it’s ready.

Cooking Tips & Techniques

French toast casseroles can sometimes get soggy or dry if you’re not careful — I’ve been there! One trick I learned is to use day-old or lightly toasted bread cubes to soak up just the right amount of custard without turning into mush. Also, blending softened cream cheese into the custard adds a silky richness that keeps the texture just right.

When mixing berries in, be gentle. You want those juicy pops of flavor without turning your dish into a berry soup. If you want a crispier top, you can sprinkle a little brown sugar or chopped nuts before baking. I’ve found that tenting the dish with foil halfway through baking prevents the top from getting too dark while ensuring the inside cooks through.

Timing-wise, prepping the night before is a no-brainer for busy mornings. While it bakes, you can multitask by prepping coffee or setting the table. Just make sure your oven temperature is spot on to avoid undercooking or drying out the casserole.

Variations & Adaptations

• Dairy-Free: Swap whole milk and heavy cream with coconut or almond milk, and use a dairy-free cream cheese alternative.
• Gluten-Free: Use gluten-free bread (I’ve tried this with a dense gluten-free brioche style — works beautifully).
• Flavor Twists: Try adding a teaspoon of orange zest for a citrus note or sprinkle in some chopped pecans or walnuts for extra crunch.
• Seasonal Swaps: In fall or winter, swap berries for diced apples or pears with a pinch of nutmeg and brown sugar.
• Extra Rich: Stir in a tablespoon of bourbon or rum into the custard for a boozy brunch treat that tastes like a secret indulgence.

Personally, I once added a swirl of homemade raspberry jam before baking — it added a delightful tart contrast and made the casserole feel like a dessert breakfast.

Serving & Storage Suggestions

This casserole is best served warm, straight from the oven, with a dusting of powdered sugar and a drizzle of maple syrup. Pair it with fresh fruit, crispy bacon, or a side of Greek yogurt to balance the sweetness. For drinks, a strong cup of coffee or a glass of fresh orange juice complements the berry notes wonderfully.

Leftovers? No problem! Store covered in the refrigerator for up to 3 days. To reheat, microwave individual portions for about 60 seconds or warm in a 325°F (160°C) oven for 10-15 minutes until heated through. The flavors actually deepen a bit after resting overnight in the fridge — a happy bonus.

FAQs

Can I use frozen berries in this casserole?

Absolutely! Frozen berries work just fine—just sprinkle them over the bread as you would fresh. They’ll thaw and release juices during soaking, adding great flavor.

Sturdy breads like brioche, challah, or thick-cut French bread are ideal because they soak up custard without turning mushy. Day-old bread or lightly toasted cubes are perfect.

Can I prepare this casserole the morning of instead of overnight?

You can, but the flavors and custard absorption won’t be quite as developed. If you’re short on time, let it soak for at least 1 hour before baking.

How do I prevent the casserole from getting soggy?

Using slightly stale or toasted bread helps, and pressing the bread gently into the custard ensures even soaking. Also, avoid folding berries too harshly to keep the texture intact.
