Ingredients & Substitutions

Ingredient List

French Toast Base

• 8 large bakery croissants, cubed into 1-inch pieces
• 3 tablespoons salted butter, melted
• 12 ounces cream cheese, softened
• ¾ cup granulated sugar
• 5 large eggs, at room temperature
• ¾ cup heavy cream, at room temperature
• ¾ cup whole milk, at room temperature
• 1 teaspoon almond extract
• ¼ teaspoon fine sea salt
• 1 tablespoon orange juice
• 1½ teaspoons orange zest
• 1 pint fresh blueberries, divided
• ½ pint fresh raspberries, divided

Orange Almond Glaze

• 1 cup powdered sugar
• ½ teaspoon almond extract
• 1 tablespoon orange juice
• 1–2 tablespoons heavy cream
• Sliced almonds (optional)

Notes on Quality

• Use day-old or slightly stale croissants so they soak up the custard without turning mushy.
• Soften cream cheese until it’s super smooth—nuking it in the microwave for 10–15 seconds helps.
• Choose full-fat dairy for best richness.
• Fresh citrus makes all the difference in the glaze and custard. Zest your orange before juicing it.

Possible Substitutions

• Croissants: Swap in brioche or challah if croissants aren’t available.
• Berries: You can use frozen blueberries or raspberries. Add them in frozen to prevent extra liquid.
• No almond extract? Sub in vanilla extract or lemon zest for a different spin.
• Dairy-Free: Use plant-based cream cheese, almond milk, and coconut cream.

Step-by-Step Instructions

1. Prep the baking dish: Preheat oven to 350°F. Spray a 9×13-inch dish with nonstick spray.
2. Toast the croissants: Spread cubed croissants on a baking sheet. Drizzle with melted butter and lightly toss. Toast in the oven for 6 to 8 minutes, stirring once or twice. Let cool.
3. Make the custard: In a large bowl, beat softened cream cheese and sugar until fluffy. Add eggs and mix. Slowly incorporate the heavy cream, milk, almond extract, salt, orange juice, and zest. Mix until fully combined.
4. Soak croissants: Gently fold the croissants into the custard using a wooden spoon. Let sit for 5 minutes, then fold again to ensure even coating.
5. Layer the casserole: Pour half the croissant mixture into the baking dish. Top with half the blueberries and raspberries. Add the remaining croissants and custard, followed by the rest of the berries.
6. Chill overnight: Cover tightly with foil and refrigerate at least 8 hours or overnight.
7. Bake: When ready to bake, let the dish sit at room temp while oven preheats. Bake at 350°F for 30 minutes covered. Remove foil and bake another 15–20 minutes, until golden and set.
8. Glaze: Whisk together powdered sugar, almond extract, orange juice, and 1 tablespoon cream. Adjust texture with more cream or sugar if needed. Drizzle over warm casserole and top with sliced almonds if using.

Expert Tips & Tricks

Best Practices

• Use stale croissants for the best texture—they’ll soak in more flavor without falling apart.
• Don’t skip the toasting step. It adds structure and a subtle crunch to the dish.
• Let the casserole rest before slicing to help the custard firm up.

Common Mistakes

• Cream cheese too cold: This causes lumps. Make sure it’s very soft.
• Using warm custard: Don’t pour it over the croissants hot. Let it cool slightly to avoid cooking the eggs prematurely.
• Skipping overnight chill: This step is crucial to allow full custard absorption.

Time-Saving Tips

• Toast and cube croissants a day early.
• Mix the glaze while the casserole bakes.
• Want to serve sooner? Chill for at least 4 hours, but overnight is best.

Serving Suggestions

Pairings

• A simple arugula or citrus salad balances the richness beautifully.
• Add a side of crispy bacon or sausage for extra protein.
• Serve with soft scrambled eggs or this French Omelette with Fines Herbes.

Presentation Ideas

• Dust with powdered sugar just before serving.
• Serve from a casserole dish or cut into squares for a more elegant plate.
• Garnish with extra fresh berries and mint leaves.

Beverage Pairings

• Brunch classics: mimosas, Bellinis, or a light Prosecco
• Coffee with a hint of orange zest or cinnamon
• Herbal teas like chamomile or lavender complement the citrus-almond notes

Storage & Reheating

Leftover Storage

• Store leftovers in an airtight container in the refrigerator for up to 3 days.
• Avoid storing with the glaze already on if you plan to reheat—it’s better added fresh.

Reheating Methods

• Oven: Cover with foil and warm at 300°F for 15 minutes.
• Microwave: Reheat individual portions for 30–60 seconds. Add fresh glaze afterward.

Frequently Asked Questions

Substitutions & Adjustments

Can I make this gluten-free? Yes, use gluten-free croissants or swap for gluten-free brioche.

Troubleshooting
