Step‑by‑Step Instructions for Croque Madame Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This warm-up time ensures that when you place your Croque Madame Casserole inside, it bakes evenly and rises beautifully. While the oven is heating, gather your ingredients and prepare your baking dish by greasing it with butter or cooking spray to prevent sticking.

Step 2: Prepare the Béchamel Sauce
In a medium saucepan over medium heat, melt 4 tablespoons of butter. Once melted, whisk in 4 tablespoons of flour, stirring constantly for about 2 minutes until it forms a paste. Gradually pour in 2 cups of milk while whisking to avoid lumps. Cook until the béchamel thickens, about 5–7 minutes, and then season with a touch of Dijon mustard and a sprinkle of nutmeg, stirring well.

Step 3: Assemble the Casserole Base
In a large mixing bowl, tear or cut slightly stale brioche into cubes. Place half of the brioche cubes evenly in the greased casserole dish, ensuring they cover the base. Next, pour half of the creamy béchamel sauce over the brioche, using a spatula to gently mix it in. This ensures that each piece of bread is well-soaked and flavorful.

Step 4: Add Layers of Ham and Cheese
Now, lay down slices of turkey ham evenly over the soaked brioche. Follow this with a generous topping of grated Gruyère cheese, allowing the melty goodness to cascade across the ham. Then, pour the remaining béchamel sauce over this layer, ensuring everything is covered and blended together for that decadent level of flavor.

Step 5: Prepare the Egg Mixture
In a separate bowl, whisk together 4 eggs and 1/2 cup of heavy cream until the mixture is smooth. This mixture will provide the finishing touch on your Croque Madame Casserole. Carefully pour it over the top of the assembled casserole, making sure it seeps into all the layers for added richness and creaminess.

Step 6: Bake to Perfection
Place the casserole in your preheated oven and bake for about 40 minutes. You’ll know it’s ready when the top is golden brown and bubbly, creating a beautiful crust. For a finishing touch, crack a couple of eggs on top of the casserole during the last 10 minutes of baking to achieve that quintessential Croque Madame look and flavor.

Step 7: Let Rest Before Serving
Once baked, remove your Croque Madame Casserole from the oven and let it sit for about 10 minutes. This resting period allows the layers to set and makes serving easier. The golden, creamy layers are now ready to be enjoyed, dotted with perfectly runny yolks from the added eggs.

Step 8: Serve and Delight
Finally, slice into your Croque Madame Casserole, and serve warm with a fresh green salad or sliced fruits. This dish is perfect for brunch, bringing together the flavors and comforts of a classic French favorite enjoyed right at your table.

Expert Tips for Croque Madame Casserole

  • Stale Bread is Key: Use slightly stale brioche for the best texture—fresh bread can become soggy. If using fresh, give it a light toast first.

  • Egg Perfection: Keep an eye on the eggs during baking to avoid overcooking. The yolks should remain runny, adding a lovely richness to the dish.

  • Béchamel Balance: When preparing the béchamel sauce, whisk constantly to prevent lumps and ensure a silky sauce that binds the casserole.

  • Make-Ahead Option: You can prep the casserole the night before and refrigerate it, allowing the flavors to meld beautifully before baking the next morning.

  • Experiment with Substitutes: Feel free to swap out turkey ham for variations like sautéed mushrooms or spinach for a vegetarian twist on the classic Croque Madame.

Croque Madame Casserole Recipe FAQs

How should I choose the brioche for the casserole?
Absolutely! When selecting brioche, look for slightly stale bread as it absorbs the béchamel sauce without becoming soggy. Fresh brioche can be used, but I recommend lightly toasting it before cubing to maintain texture.

What’s the best way to store leftover Croque Madame Casserole?
For optimum freshness, store any leftover casserole covered in the refrigerator for up to 3 days. To reheat, simply pop individual portions in the microwave or place them in a preheated oven for a few minutes until heated through.

Can I freeze Croque Madame Casserole, and how do I do it?
Yes, you can! To freeze the casserole before baking, wrap it tightly with plastic wrap and aluminum foil for up to 2 months. When you’re ready to enjoy it, thaw it overnight in the fridge. Bake at 350°F (175°C) for about 40 minutes, checking for that glorious golden top!

What if my béchamel sauce turns lumpy?
Don’t worry! If your béchamel sauce becomes lumpy, simply remove it from the heat and whisk vigorously until the lumps break apart. If needed, use an immersion blender to create a smoother consistency before adding it back to the heat.

Can I make this casserole vegetarian?
Very much so! To adapt it for a vegetarian option, simply replace the turkey ham with sautéed mushrooms, spinach, or roasted bell peppers. The rich flavors of the béchamel and melty cheese will ensure it’s still a crowd-pleaser!
