What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without the fuss. Most are pantry staples, with the star being the sparkling champagne that adds a light and airy feel to the casserole. Here’s what you’ll gather:

• For the Casserole Base:
• 6 large eggs, room temperature (for a fluffy, rich custard)
• 2 cups whole milk or half-and-half (adds creaminess; use dairy-free milk if preferred)
• 1 cup sparkling champagne (I recommend Brut style for a balanced dryness)
• 1 teaspoon pure vanilla extract (just a touch for warmth)
• Salt and freshly ground black pepper to taste
• For the Filling:
• 4 cups cubed day-old French bread or brioche (stale bread soaks up the custard perfectly)
• 1 ½ cups shredded sharp cheddar cheese (for melty, tangy goodness)
• 1 cup cooked breakfast sausage or diced ham (optional, but adds savory depth)
• ½ cup diced green onions or chives (fresh pop of flavor)
• 1 cup sliced mushrooms or sautéed spinach (optional for veggie lovers)
• For the Topping:
• ½ cup shredded Gruyère or mozzarella cheese (creates a golden, bubbly crust)
• Fresh herbs like parsley or thyme for garnish (adds color and freshness)

For best results, pick a good-quality champagne or sparkling wine you enjoy drinking—this really makes a difference. If you want to keep it alcohol-free, substitute with sparkling white grape juice or club soda, but the flavor will shift slightly. Also, if you’re gluten-sensitive, try swapping the bread for gluten-free cubes or even cubed cooked potatoes for a twist.

Equipment Needed

• 9×13-inch baking dish (glass or ceramic works great for even cooking and presentation)
• Large mixing bowl (to whisk together custard ingredients smoothly)
• Whisk or electric mixer (to beat eggs and champagne for fluffiness)
• Measuring cups and spoons (for precise ingredient amounts)
• Nonstick skillet (if you’re cooking sausage or sautéing veggies beforehand)
• Rubber spatula (perfect for folding in ingredients without deflating the mix)
• Aluminum foil (to cover the casserole while baking to prevent over-browning)

If you don’t have a 9×13-inch dish, a similarly sized casserole or oven-safe pan will do. I personally like using glass because I can see the bubbling edges as it cooks—always reassuring! For budget-friendly options, simple stoneware pans from basic kitchenware stores work just fine, and they’re easy to clean. Just make sure your baking dish is oven-safe up to 350°F (175°C).

Preparation Method

1. Preheat your oven to 350°F (175°C). Lightly grease your 9×13-inch baking dish with butter or nonstick spray to keep the casserole from sticking.
2. Prepare the bread cubes: Cut day-old French bread or brioche into 1-inch cubes. Stale bread soaks up the custard better, but if your bread is fresh, toast the cubes lightly in the oven for about 10 minutes to dry them out.
3. Cook any fillings: If using sausage, cook it in a skillet over medium heat until browned and cooked through, about 5-7 minutes. Drain excess fat. Sauté mushrooms or spinach if desired, cooking until just wilted. Set aside to cool slightly.
4. Mix the custard: In a large bowl, whisk together 6 large eggs, 2 cups whole milk or half-and-half, and 1 cup sparkling champagne until combined. Add 1 teaspoon vanilla extract, salt (about 1 teaspoon), and freshly ground black pepper (about ½ teaspoon). Whisk until the mixture is smooth and slightly frothy.
5. Assemble the casserole: In the prepared baking dish, layer the bread cubes evenly. Sprinkle the cooked sausage or ham, sautéed veggies, green onions, and 1 ½ cups shredded cheddar cheese over the bread. Pour the champagne custard mixture evenly over everything, gently pressing down to soak the bread cubes.
6. Let it rest: Allow the casserole to sit at room temperature for 10-15 minutes so the bread absorbs the custard fully. This step helps ensure a creamy texture inside rather than dry spots.
7. Add the topping: Sprinkle ½ cup shredded Gruyère or mozzarella cheese evenly over the top for a golden crust.
8. Bake: Cover loosely with aluminum foil and bake in the preheated oven for 40 minutes. Remove the foil and bake for an additional 15-20 minutes until the top is bubbly and golden brown, and a toothpick inserted in the center comes out clean.
9. Rest before serving: Let the casserole cool for 5-10 minutes to set up slightly. Garnish with fresh herbs like parsley or thyme for a pop of color and fresh aroma.

Pro tip: If you notice the top browning too quickly, tent with foil again to avoid burning while the inside finishes cooking. Also, the bubbly champagne scent when it comes out of the oven is your cue that brunch is ready to be served!

Cooking Tips & Techniques

To get the best results from your Easy Sparkling Champagne Breakfast Casserole, here are some tips I’ve picked up through trial and error:

• Use day-old bread: Fresh bread can make your casserole soggy. Dry bread soaks up custard better, resulting in a perfect custardy inside and a crispy top.
• Don’t skip the resting time: Letting the casserole sit before baking ensures the bread fully absorbs the liquid, avoiding dry patches.
• Beat the eggs and champagne well: Whisking thoroughly adds air for a lighter texture. You want a smooth, frothy custard base.
• Cover during most of the bake: This prevents the top from over-browning while the inside cooks through.
• Customize fillings mindfully: Too many wet veggies can make the casserole watery. Sauté them first to reduce moisture.
• Choose your cheese wisely: Sharp cheddar adds flavor, but a mix with Gruyère or mozzarella for topping gives a great melt and crust.
• Multitask while it bakes: Use the baking time to prep side dishes, drinks, or tidying up—hands-free cooking is a win!

I once forgot to cover the casserole, and the top turned almost burnt before the inside was done. Lesson learned—foil is your friend. Also, if you want an extra fluffy texture, try folding in a little whipped egg whites separately for a delicate lift.

Variations & Adaptations

Want to switch things up? This Easy Sparkling Champagne Breakfast Casserole is super versatile and adapts well to different tastes and diets.

• Vegetarian Version: Skip the meat and add sautéed mushrooms, bell peppers, or sun-dried tomatoes for a flavorful veggie-packed casserole.
• Gluten-Free: Swap the bread cubes for gluten-free bread or use cooked quinoa or rice as a base for a different texture.
• Dairy-Free: Use dairy-free milk alternatives like almond or oat milk and dairy-free cheese substitutes. Make sure to pick a champagne that’s vegan-friendly.
• Sweet Brunch Twist: Replace savory fillings with fresh berries, chopped nuts, and a sprinkle of cinnamon. Swap cheddar for cream cheese dollops and drizzle with honey after baking.
• Different Cooking Methods: This casserole can also be baked in individual ramekins for personalized servings or cooked in a slow cooker on low for 3-4 hours if you want to prep ahead.

Personally, I tried adding smoked salmon with dill and capers once, and it gave the casserole a fancy brunch vibe that wowed my friends. Feel free to experiment with herbs and cheeses to make it your own.

Serving & Storage Suggestions

Serve this casserole warm for the best experience—its bubbly cheese and champagne aroma are at their peak. Pair it with fresh fruit salad, roasted potatoes, or a light green salad to balance the richness. For drinks, a mimosa or fresh-squeezed orange juice complements the sparkling champagne flavors beautifully.

If you have leftovers (though rare!), store them in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 325°F (160°C) for 10-15 minutes or in the microwave, covered, until warmed through. The casserole tends to firm up as it cools, so reheating slowly helps retain moisture.

Fun fact: letting the casserole sit overnight in the fridge before baking actually deepens the flavors and makes slicing neater for brunch gatherings. Just cover it tightly and pop it in the fridge after assembling.
