Croque-Madame Ingredients

• Ready to create this delightful dish? Here’s what you’ll need!

For the Mornay Sauce

Butter – Adds richness and helps in creating the Mornay sauce; use unsalted for better control over seasoning.
All-Purpose Flour – Acts as a thickening agent for the Mornay sauce; feel free to substitute with gluten-free flour if needed.
Salt – Enhances flavor; always adjust to taste for the best results.
White Pepper – Provides subtle heat without altering the sauce’s appearance; black pepper works if that’s what you have.
Ground Nutmeg – Adds a warm, aromatic touch to the sauce; can be omitted if preferred.
2% Milk – Creates a lovely creamy base for the sauce; opt for whole milk if you crave extra richness.
Gruyere Cheese – The star ingredient for flavor and meltiness; Emmental or a blend of cheeses can work as substitutes too.

For the Sandwich

Thick-Sliced Country Bread – The sturdy foundation for your sandwich; switch it up with sourdough or ciabatta for a different texture.
Fully Cooked Ham – Provides protein and a delightful savory flavor; for a vegetarian option, consider turkey or omit the meat altogether.
Dijon Mustard (optional) – Introduces an exciting tang; replace it with whole grain mustard or skip it for a milder taste.

For Topping

Large Eggs – Crown your sandwich with a fried egg for richness and protein; organic eggs are a great choice for better quality.

Now that you have your ingredient list, it’s time to dive into creating a Croque-Madame that will elevate your brunch experience!

Step‑by‑Step Instructions for Croque-Madame

Step 1: Prepare Mornay Sauce
In a small saucepan over medium heat, melt 2 tablespoons of unsalted butter until bubbling. Whisk in 2 tablespoons of all-purpose flour, 1/2 teaspoon of salt, 1/4 teaspoon of white pepper, and a pinch of ground nutmeg, cooking for about 1 minute until smooth. Gradually add 2 cups of milk, stirring constantly until the mixture thickens and gently bubbles. Remove from heat and mix in 1 cup of grated Gruyere cheese until melted and creamy; keep warm.

Step 2: Assemble Sandwiches
Lay out two thick slices of country bread and spread 2 tablespoons of the warm Mornay sauce on each slice. Layer with slices of fully cooked ham and add 1/4 cup of Gruyere cheese on top. If desired, spread Dijon mustard on the remaining two slices of bread and place them on top, mustard side down. Finish by buttering the outsides of both assembled sandwiches for that beautiful golden crust.

Step 3: Toast Sandwiches
Heat a skillet over medium heat and place the sandwiches inside. Toast them for about 2-3 minutes on each side until the bread is golden brown and the cheese is melty. You may need to press down gently with a spatula to ensure even browning and melting without burning. The Croque-Madame should have a lovely crispy exterior when done.

Step 4: Broil
Once the sandwiches are toasted, transfer them to an oven-safe dish. Spread the remaining Mornay sauce evenly over the top of each sandwich and sprinkle with any leftover Gruyere cheese. Place under a broiler set to high for 2-3 minutes, or until the cheese is bubbly and lightly browned. Keep a close watch to prevent burning, as broilers can be quite quick!

Step 5: Fry Eggs
While the sandwiches are broiling, heat another skillet over medium heat and add a little butter. Crack in two large eggs, cooking for about 3-4 minutes until the whites are set but the yolks remain slightly runny. Remove from heat when done, and gently place one fried egg on top of each Croque-Madame sandwich for that delightful finishing touch.

Make Ahead Options

Preparing your Croque-Madame ahead of time makes busy mornings a breeze! You can make the Mornay sauce in advance, storing it in the refrigerator for up to 5 days. To keep it smooth, reheat gently and whisk in a splash of milk if necessary. Additionally, assemble the sandwiches (excluding the egg) and refrigerate them for up to 24 hours; this helps the flavors meld beautifully without compromising quality. When you’re ready to serve, simply toast the sandwiches as directed, broil to achieve that golden top, and fry the eggs just before serving to ensure they’re fresh and delicious. This way, your homemade Croque-Madame will be just as indulgent with minimal effort!

How to Store and Freeze Croque-Madame

Fridge: Store any leftover Croque-Madame in an airtight container in the fridge for up to 3 days. Reheat in a skillet to maintain crispiness.

Freezer: If you want to freeze, wrap each sandwich tightly in plastic wrap and then place in a freezer bag for up to 1 month. Reheat directly from frozen, placing in an oven until heated through.

Mornay Sauce: You can store any extra Mornay sauce in the fridge for up to 5 days. Reheat gently on the stove and whisk until smooth before serving with your Croque-Madame.

Reheating: For the best texture, reheat the sandwiches in a skillet rather than the microwave, as it helps retain the crispy exterior that makes the Croque-Madame so delicious.

Croque-Madame Variations & Substitutions

Feel free to make this delightful Croque-Madame your own with these easy and tasty variations!

Gluten-Free: For a gluten-free version, use gluten-free bread and flour in the Mornay sauce, ensuring everyone can enjoy this classic.
Spicy Kick: Add a dash of cayenne pepper to the Mornay sauce for an unexpected heat that amplifies flavor. This little addition could become your new favorite twist!
Flavored Mustard: Experiment with a spiced or whole-grain mustard for an extra punch of flavor that harmonizes wonderfully with the richness of the cheese and ham.
Breakfast Twist: Transform it into a breakfast dish by adding sautéed spinach and a sunny-side-up egg instead of a fried egg for an added layer of vegetables and nutrients.
Herb Infusion: Mix fresh herbs like thyme or chives into your Mornay sauce for a fragrant herbal boost that brightens every bite.
Gourmet Toast: For a refined twist, use artisan bread like brioche or focaccia to give the Croque-Madame a gourmet touch, perfect for impressing guests during brunch.

Expert Tips for the Best Croque-Madame

Perfect Mornay Sauce: Ensure your Mornay sauce is lump-free by whisking thoroughly after adding the milk. This will create a smooth and creamy base for your Croque-Madame.
Choose the Right Bread: A thick, sturdy bread is essential to support the ingredients. Avoid using thin slices, as they may get soggy or fall apart while toasting.
Golden-Brown Finish: Keep an eye on your sandwiches while toasting and broiling. Adjust the heat as needed to achieve that beautiful golden crust without burning.
Egg Cooking Tips: For a perfectly runny yolk, cook the eggs just until the whites are set. This adds a delightful creaminess when you cut into the sandwich.
Serve Immediately: Enjoy your Croque-Madame right after cooking for optimal texture and flavor, as reheating can diminish its crispiness.

Croque-Madame Recipe FAQs

What kind of bread is best for Croque-Madame?
For a classic Croque-Madame, thick-sliced country bread is ideal as it provides the necessary support to hold the layers of delicious fillings. I often recommend sourdough or ciabatta for a different texture; just make sure the bread is sturdy to prevent it from becoming soggy during toasting.

How long can I store leftovers in the fridge?
Absolutely! You can store leftover Croque-Madame in an airtight container in the fridge for up to 3 days. When it’s time to enjoy them again, reheat in a skillet to maintain that crispy texture you love. The oven can work too, but the skillet is my go-to for keeping them wonderfully crunchy.

Can I freeze Croque-Madame?
Yes! If you’re looking to freeze your Croque-Madame, wrap each sandwich individually in plastic wrap, and then place them in a freezer bag to protect against freezer burn. They can be frozen for up to 1 month. When you’re ready to enjoy, cook them straight from frozen in the oven, which will allow them to heat through while remaining crispy.

What if my Mornay sauce turns out lumpy?
Don’t worry! If your Mornay sauce ends up with lumps, simply whisk vigorously while adding the milk to prevent clumping. If it’s already lumpy, you can strain the sauce through a fine-mesh sieve to remove the lumps and then return it to low heat, whisking until smooth once more. The key to a perfect sauce is patience and gentle heat!

Is Croque-Madame suitable for vegetarians?
Absolutely! You can easily make a vegetarian version of Croque-Madame by omitting the ham and adding ingredients like sautéed mushrooms or spinach for extra flavor and nutrition. Just be sure to keep the rich Mornay sauce to maintain that comforting essence of the dish.

Can I prepare the Mornay sauce ahead of time?
Yes! You can make the Mornay sauce ahead of time and store it in the refrigerator for up to 5 days. When you’re ready to use it, simply reheat it gently on the stove, whisking until smooth again before pouring over your assembled sandwiches. This makes your brunch prep so much easier!
