Step‑by‑Step Instructions for Croque Madame Casserole

Step 1: Prepare the Béchamel Sauce
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Whisk in 1/4 cup of flour to form a roux, cooking for about 2 minutes until golden and bubbling. Gradually add 2 cups of whole milk, stirring constantly for 5–7 minutes until the mixture thickens. Stir in 1 teaspoon of Dijon mustard and a dash of nutmeg, then remove from heat and set aside.

Step 2: Layer the Ingredients
Preheat your oven to 350°F (175°C). In a greased 9×13-inch baking dish, create the first layer with 4 cups of slightly stale brioche cubes, spreading them evenly across the bottom. Next, layer 8 ounces of sliced turkey ham, followed by 1 cup of shredded Gruyère cheese. Pour the prepared béchamel sauce evenly over the top, ensuring all layers are covered.

Step 3: Bake the Casserole
Place the casserole in the preheated oven and bake for 30–35 minutes, or until the top is golden brown and bubbly. You’ll know it’s ready when the edges are slightly puffed and the béchamel is bubbling around the sides. Keep an eye out for that delicious golden hue, as it indicates the perfect doneness.

Step 4: Add the Eggs
During the last 10 minutes of baking, carefully remove the casserole from the oven. Crack 6 eggs gently onto the surface, spacing them out evenly. Return the dish to the oven and bake for an additional 8–10 minutes, until the egg whites are set and the yolks are still slightly runny. This step adds richness to your Croque Madame Casserole.

Step 5: Serve and Enjoy
Once baked, remove the casserole from the oven and let it cool for about 5 minutes. Serve warm, garnished with fresh herbs if desired. This Croque Madame Casserole is best enjoyed straight from the oven, showcasing its creamy layers and golden eggs, perfect for brunch gatherings or a cozy breakfast-for-dinner delight.
