Step‑by‑Step Instructions for Croque Madame Casserole

Step 1: Prepare Béchamel
In a saucepan over medium heat, melt 4 tablespoons of butter. Once melted, whisk in ¼ cup of flour, cooking for about 1-2 minutes until golden. Gradually add 2 cups of milk while continuously stirring to avoid lumps. Cook until thickened, about 5 minutes. Stir in 1 tablespoon of Dijon mustard, a pinch of nutmeg, salt, and pepper to taste, ensuring a rich, creamy béchamel.

Step 2: Layer Ingredients
Grease a 9×13-inch casserole dish with butter. Begin layering by placing 6 cups of cubed brioche at the bottom, ensuring even coverage. Add 1 cup of smoky turkey ham on top, followed by 1½ cups of grated Gruyère cheese. Pour the warm béchamel sauce evenly over these layers, making sure every piece is coated for that irresistible Croque Madame flavor.

Step 3: Add Eggs
Using the back of a spoon, create small wells in the casserole for each egg—typically, you’ll want to create 4 wells. Crack an egg into each well, taking care not to break the yolks. This unique touch is what truly makes it a Croque Madame casserole, and it will enhance the dish’s beauty and flavor as the eggs bake to perfection.

Step 4: Bake the Casserole
Cover the casserole dish with aluminum foil and bake in a preheated oven at 350°F (175°C) for 25 minutes. Remove the foil and continue baking for an additional 10-15 minutes. Look for a golden-brown top and a slightly puffed texture, assuring that your Croque Madame Casserole is bubbling with deliciousness and ready to serve.

Step 5: Serve and Enjoy
Once baked, remove the casserole from the oven and let it cool for about 5-10 minutes. This brief resting period allows the layers to set, making it easier to serve. Dish out generous portions and pair with a light salad or seasonal fruit for a delightful brunch experience. Each slice reveals creamy layers and beautiful runny egg yolks, embodying the essence of a truly comforting Croque Madame!

How to Store and Freeze Croque Madame Casserole

Fridge: Keep leftover Croque Madame Casserole covered in an airtight container for up to 3 days. Reheat in the oven or microwave until heated through, ensuring the creamy layers maintain their delightful texture.

Freezer: For longer storage, assemble the casserole without baking, cover tightly with plastic wrap, and then foil. Freeze for up to 2 months. Bake straight from the freezer, adding a few extra minutes to the cooking time.

Reheating: When reheating thawed casserole, heat in a 350°F (175°C) oven until hot and bubbly, about 25-30 minutes. This ensures the enchanting flavors of the Croque Madame are preserved.

Make-Ahead: Feel free to prepare it a day in advance and store it in the fridge before baking, making it an ideal dish for brunch prep!

Expert Tips for Croque Madame Casserole

• Use Day-Old Bread: Opt for slightly stale brioche, which absorbs the béchamel without becoming mushy. Fresh bread can lead to a soggy texture.

• Layer Wisely: Ensure even distribution of turkey ham and Gruyère cheese between brioche layers for balanced flavor throughout the casserole.

• Perfect Egg Technique: Add eggs during the last 10 minutes of baking to achieve that coveted runny yolk, enhancing your Croque Madame experience.

• Meal Prep Friendly: Assemble the casserole the night before and store in the fridge. Just pop it in the oven in the morning for an effortless brunch!

• Lighter Variations: Swap out whole milk for low-fat milk combined with Greek yogurt to create a lighter béchamel, fitting for a healthier lifestyle.

Croque Madame Casserole Recipe FAQs

How do I select ripe ingredients for the Croque Madame Casserole?
Absolutely! For the brioche, look for a loaf that’s slightly aged, as this will absorb the béchamel sauce without becoming overly soggy; day-old bread works best. Check for a golden color and a slightly firm texture. When selecting Gruyère cheese, aim for a creamy, firm block with a robust nutty aroma, and for turkey ham, choose high-quality slices that are moist and flavorful.

What is the best way to store leftover Croque Madame Casserole?
Make sure to keep any leftovers in an airtight container in the fridge for up to 3 days. Reheating is best done in the oven or microwave until hot throughout—this way, you can continue enjoying those creamy layers! Alternatively, if you have assembled the casserole but haven’t baked it yet, you can cover it tightly and refrigerate overnight before popping it into the oven the next day.

Can I freeze Croque Madame Casserole?
Absolutely! To freeze, assemble your casserole without baking. Cover it tightly with plastic wrap, followed by aluminum foil to prevent freezer burn. It can be frozen for up to 2 months. When you’re ready to enjoy, bake it straight from the freezer, adding about 10 minutes to the cooking time to ensure it’s heated through.

What if my casserole is too soggy?
The primary culprit for a soggy casserole is fresh bread. I recommend using day-old brioche or lightly toasting fresh brioche before using it. If your béchamel sauce is too runny, make sure to let it cook long enough to thicken, about 5 minutes after adding the milk. And remember, spreading your ingredients evenly helps absorb moisture effectively!

Are there any dietary considerations for this recipe?
For those with gluten sensitivities, you can make a delicious gluten-free version by choosing gluten-free bread and substituting cornstarch for flour in the béchamel. Additionally, if you or your guests have allergies to dairy, consider using plant-based milk alternatives and vegan cheeses that melt well. Always double-check ingredient labels to ensure everything fits within your dietary needs!

How long does Croque Madame Casserole last in the fridge?
Keep your leftovers in the fridge, covered, for up to 3 days. When you’re ready to reheat, warm it lovingly in the oven to ensure the flavors stay bright and the texture remains delightful—about 15-20 minutes at 350°F (175°C) should do the trick!
