Croque Madame Casserole Ingredients
For the Casserole Base

• Butter – Essential for a rich base; don’t skip this creamy component!
• Flour – Used to create a roux that thickens the sauce; keep stirring to avoid lumps.

Step‑by‑Step Instructions for Croque Madame Casserole
Step 1: Prepare the Béchamel Sauce
In a medium saucepan over medium heat, melt 4 tablespoons of butter. Once melted, whisk in ¼ cup of flour to create a roux, stirring constantly for about 2 minutes until it becomes slightly golden. Gradually pour in 2 cups of whole milk, whisking continuously until the sauce thickens (about 5-7 minutes). Stir in 1 tablespoon of Dijon mustard, a pinch of nutmeg, and season to taste with salt and pepper.
Step 2: Layer the Ingredients
Preheat your oven to 375°F (190°C). In a generously greased 9×13-inch baking dish, layer 6 cups of slightly stale brioche cubes evenly across the bottom. Then, add 8 ounces of sliced turkey ham and sprinkle 1 ½ cups of shredded Gruyère cheese on top. Pour the prepared béchamel sauce over the layers, ensuring everything is evenly coated for a creamy Croque Madame experience.
Step 3: Individual Portions (Optional)
If you prefer to serve separate portions, preheat your oven and use individual ramekins instead. Spoon equal amounts of the brioche, turkey ham, and Gruyère mixture into each ramekin, pouring béchamel sauce over until just covered. This makes for a charming presentation for your guests at brunch or dinner while keeping the rich, comforting flavors intact.
Step 4: Bake the Casserole
Place your baking dish (or ramekins) in the preheated oven and bake for about 30-35 minutes, or until the top is golden brown and bubbly. You’ll know it’s ready when the edges start to pull away from the sides and a delicious aroma fills your kitchen, enticing everyone to gather around the table for your Croque Madame Casserole.
Step 5: Add the Eggs
In the last 10 minutes of baking, carefully remove the casserole from the oven. Gently crack 6 eggs on top, spacing them evenly to allow for runny yolks. Return to the oven and bake for an additional 10-12 minutes, or until the egg whites are set while the yolks remain slightly runny, giving that classic Croque Madame touch to your dish.
Storage Tips for Croque Madame Casserole
Room Temperature: Keep the casserole at room temperature for up to 2 hours after baking; serve immediately for the best flavor and texture.
Fridge: Store leftovers in an airtight container for up to 3 days; reheat slices in the oven or microwave until warmed through.
Freezer: Freeze the unbaked casserole tightly wrapped for up to 2 months; thaw overnight in the fridge before baking.
Reheating: When ready to enjoy, bake at 350°F for 30-35 minutes, adding a splash of milk to retain moisture and ensure a delightful Croque Madame experience.

Croque Madame Casserole Recipe FAQs
How do I select the best brioche for this recipe?
Absolutely! When choosing brioche, look for a loaf that’s slightly stale; this helps it soak up the béchamel without becoming mushy. Fresh brioche can be lightly toasted before cubing to achieve a similar effect. If you can, inspect for a golden, soft texture without any dark spots or dryness.
What is the best way to store leftovers of this casserole?
Very! Store any leftover Croque Madame Casserole in an airtight container in the fridge for up to 3 days. When ready to reheat, place slices in the oven at 350°F until warmed through, which keeps the casserole’s creamy essence intact.
Can I freeze this dish?
Absolutely! To freeze the uncooked casserole, wrap it tightly in plastic wrap and then foil, allowing it to last for up to 2 months. When you’re ready to bake, thaw it overnight in the fridge and cook as directed, possibly adding a splash of milk before baking to maintain moisture.
What should I do if the top of my casserole browns too quickly?
No worries! If you notice the top browning too fast during baking, cover it loosely with aluminum foil. This prevents over-browning while allowing the inside to continue cooking. It’s all about keeping that gooey, delightful interior while achieving a perfect golden top.
Are there any dietary considerations for this recipe?
Definitely! For a gluten-free option, simply substitute brioche with gluten-free bread and ensure your béchamel sauce uses gluten-free flour. Always check your turkey ham or cheese labels for any allergens if serving to guests with dietary restrictions, making this dish inclusive for everyone!
