Croque Madame Casserole Ingredients

Explore the delightful components of this dish!

For the Casserole

Brioche – A buttery, slightly sweet base that soaks in the creamy béchamel sauce; if unavailable, challah or French bread works well.
Gruyère Cheese – Offers a nutty and creamy flavor, and melts beautifully; substitutions include Emmental or sharp white cheddar.
Turkey Ham – Adds a delicious smoky element; for a vegetarian version, try sautéed mushrooms or spinach instead.
Béchamel Sauce – A rich mixture of butter, flour, and milk that binds everything together; adding Dijon mustard and nutmeg enhances the flavor.
Eggs – Essential for that classic Croque Madame experience; add during the last 10 minutes of baking for a perfectly runny yolk.
Heavy Cream (optional) – Whisk into the béchamel for a luxurious, custard-like texture; a lower-fat option can also be used for a lighter result.

Step‑by‑Step Instructions for Croque Madame Casserole

Step 1: Prepare Béchamel Sauce
In a medium saucepan over medium heat, melt 4 tablespoons of butter until bubbling. Whisk in ¼ cup of flour to create a roux, cooking for about 2 minutes until it turns a light golden color. Gradually whisk in 2 cups of milk, stirring continuously for about 5-7 minutes until thickened. Stir in 1 tablespoon of Dijon mustard and a pinch of nutmeg for added flavor, then remove from heat.

Step 2: Assemble the Casserole
Layer approximately 6 cups of slightly stale brioche slices in a greased 9×13 inch baking dish. Pour half of the béchamel sauce over the bread, ensuring even coverage. Sprinkle 1 cup of shredded Gruyère cheese and 1 cup of diced turkey ham on top, followed by another layer of brioche. Pour the remaining béchamel sauce over this, letting it soak into the bread, then top with an additional cup of Gruyère cheese.

Step 3: Add Eggs
Using a spoon, create 4 to 6 wells gently in the top layer of the casserole, ensuring the bread is intact. Carefully crack one egg into each well, allowing the yolks to sit on top. Sprinkle a bit more Gruyère cheese over the casserole and season with salt and pepper to taste, adding a touch of freshness to your Croque Madame.

Step 4: Bake the Casserole
Preheat your oven to 350°F (175°C). Once heated, place the casserole in the oven and bake uncovered for about 30-35 minutes, or until the top is golden and bubbly, and the egg whites are set but the yolks remain runny. Keep an eye on it during the last few minutes for that perfect golden finish.

Step 5: Serve and Enjoy
Remove the Croque Madame Casserole from the oven and let it cool for about 5 minutes before serving. This cooldown helps the layers settle, ensuring a beautifully intact serving. Enjoy this decadent dish warm, perfect for brunch gatherings or a comforting breakfast-for-dinner delight that everyone will love.

Croque Madame Casserole Recipe FAQs

What type of bread is best for making Croque Madame Casserole?
Absolutely! For the best results, use slightly stale brioche, as it soaks up the béchamel sauce beautifully without becoming soggy. If you can’t find brioche, challah or thick-cut white bread are excellent substitutes as well. Just avoid using fresh bread without toasting it lightly first.

How should I store leftovers of the Croque Madame Casserole?
Very simple! Place any leftovers in an airtight container and store them in the refrigerator for up to 3 days. When you’re ready to enjoy it again, I recommend reheating it in the oven at 350°F (175°C) for about 15-20 minutes, which helps retain its yummy texture.

Can I freeze the Croque Madame Casserole?
Absolutely! You can freeze the casserole before baking. Wrap it tightly in plastic wrap and then in foil to prevent freezer burn. It can be stored for up to 2 months. To bake from frozen, preheat your oven to 350°F (175°C) and expect to add about 10-15 extra minutes to baking time.

What if my béchamel sauce is too thick?
If your béchamel ends up too thick, don’t worry! Just whisk in a little extra milk, a tablespoon at a time, over low heat until it reaches your desired consistency. This allows the sauce to blend smoothly without clumping.

Are there any allergy considerations with this recipe?
Certainly! This recipe can be adapted for various dietary needs. For those avoiding gluten, simply use gluten-free bread as a substitute. If someone is lactose intolerant, consider using lactose-free milk and cheese alternatives. Always check individual ingredients for allergens if you’re serving others.
