Ingredients You’ll Need

• Day-old croissants: The slight staleness helps them absorb the custard without becoming mushy. Fresh croissants will work in a pinch but won’t soak up as much of the delicious custard.
• Mixed berries: Add pops of color, bursts of flavor, and a touch of tartness to balance the rich custard. Fresh or frozen will work, though frozen should be kept frozen until assembly.
• Cream cheese: Creates a creamy, cheesecake-like quality throughout the casserole. Make sure it’s fully softened to avoid lumps in your custard.
• Granulated sugar: Sweetens the custard and helps the top caramelize beautifully during baking.
• Eggs: Provide structure and richness to the custard base. Room temperature eggs blend more smoothly with the other ingredients.
• Half and half: Creates a silky, rich custard without being too heavy. Whole milk can be substituted for a lighter version, or heavy cream for extra decadence.
• Vanilla extract: Adds warmth and depth to the custard, complementing both the berries and lemon.
• Lemon zest: Infuses the entire dish with bright citrus notes that wake up all the flavors.
• Butter, powdered sugar, and lemon juice: Come together to create a tangy, sweet glaze that adds the perfect finishing touch.

Variations

Flavor Twists

• Orange Cranberry: Swap the lemon zest for orange zest and use cranberries instead of mixed berries. Perfect for holiday mornings!
• Chocolate Lovers: Add chocolate chips to the mix and replace the lemon glaze with a simple chocolate drizzle.
• Almond Joy: Include sliced almonds and coconut flakes, then add a touch of almond extract to both the custard and glaze.

Fruit Options

• Substitute any berries you love – strawberries, blueberries, raspberries, or blackberries all work beautifully.
• Try diced peaches or apples (tossed with a bit of cinnamon) for a different flavor profile.

Dietary Adaptations

• Use plant-based cream cheese and milk alternatives for a dairy-sensitive version.
• Swap traditional croissants for almond or chocolate croissants for an even more indulgent treat.

How to Make Croissant Breakfast Casserole

Step 1: Prepare the Base

Place the cubed day-old croissants and mixed berries in a large mixing bowl. Spray your baking dish with non-stick spray to ensure easy serving later.

Step 2: Create the Custard

Beat the softened cream cheese and granulated sugar until smooth and creamy. Add eggs one at a time, making sure each is fully incorporated before adding the next. Slowly mix in the half and half, vanilla extract, and lemon zest until the mixture is silky and well combined.

Step 3: Combine and Soak

Pour the custard mixture over the croissants and berries, then gently toss until everything is evenly coated. Transfer to your prepared baking dish, cover, and refrigerate overnight or for at least 6 hours.

Step 4: Bake to Golden Perfection

Bring the casserole to room temperature while preheating your oven. Bake covered for 30 minutes, then remove the foil and continue baking for 15-20 minutes until golden brown and set in the center.

Step 5: Glaze and Serve

While the casserole cools slightly, prepare the lemon glaze by beating together butter, powdered sugar, half and half, lemon juice, and zest. Drizzle over the warm casserole, dust with powdered sugar, and serve to very impressed breakfast guests.

Pro Tips for Making the Recipe

• Stale is Good: If your croissants aren’t a day old, tear them up and leave them out for a few hours, or put them in a low oven (250°F) for about 10 minutes to dry them out a bit.
• Cream Cheese Success: Make sure your cream cheese is truly room temperature to avoid lumps in your custard. If you’re short on time, unwrap it and microwave in 10-second bursts until softened but not melted.
• Even Distribution: When adding the berries, distribute them evenly throughout the casserole rather than placing them all on top, which ensures berry goodness in every bite.
• Temperature Matters: Letting the casserole come to room temperature before baking ensures more even cooking and a better rise in the oven.
• Foil Technique: When covering with foil for baking, tent it slightly so it doesn’t stick to the top of the casserole as it rises.

How to Serve

Perfect Pairings

Serve this decadent casserole with a side of crispy bacon or breakfast sausage to balance the sweetness. A fresh fruit salad makes a wonderful light accompaniment.

Beverage Matches

• A bright, acidic coffee cuts through the richness perfectly
• Mimosas or Bellinis for festive occasions
• Hot tea with lemon complements the citrus notes in the casserole

Serving Style

For an elegant presentation, serve individual portions on warmed plates with extra berries and a light dusting of powdered sugar. For family-style serving, bring the whole casserole to the table with the glaze drizzled artfully over the top.

Make Ahead and Storage

Storing Leftovers

Store any leftover casserole covered in the refrigerator for up to 3 days. The flavor actually improves slightly after the first day as the lemon notes continue to develop.

Freezing

You can freeze the baked casserole (without glaze) for up to 1 month. Wrap tightly in plastic wrap and then foil. Thaw overnight in the refrigerator before reheating.

Reheating

To reheat individual portions, microwave for 60-90 seconds. For a crisper top, place in a 325°F oven for about 15 minutes. Reheat the entire casserole, covered with foil, in a 325°F oven for 20-25 minutes until warmed through.

Note: The texture may change slightly upon reheating, but the flavor remains delicious. Consider making fresh glaze for the best presentation when serving reheated portions.

FAQs

Can I assemble this the same morning instead of overnight?
While an overnight soak gives the best results, you can make this with a shorter soak time. Aim for at least 2 hours in the refrigerator, and expect a slightly less custardy result, though still delicious. You might need to reduce the baking time by about 5 minutes.

What can I substitute for half and half?
Equal parts whole milk and heavy cream make a perfect substitute for half and half. Alternatively, whole milk alone will work for a lighter version, while full heavy cream will create an extra rich result. Non-dairy milks can work but choose a creamier variety like full-fat coconut milk or oat milk.

Can I use frozen berries, and should I thaw them first?
Frozen berries work beautifully in this recipe! Keep them frozen until you’re ready to assemble the casserole – adding them while still frozen prevents them from breaking down too much and bleeding color throughout the custard.

Why did my casserole turn out soggy in the middle?
If your casserole is soggy, it may need additional baking time. Every oven is different, so look for these signs of doneness: the center should be set and not wobble when gently shaken, a knife inserted in the center should come out clean, and the top should be golden brown.
