The Croque Madame: An Iconic French Café Classic
If you’ve ever wandered into a Parisian café, you’ve likely seen the Croque Madame nestled among the menu’s classics. This sandwich, rich with sliced ham, silky béchamel, and bubbling cheese, finished with a runny fried egg, has become one of the most celebrated comfort foods in French cuisine. In this comprehensive guide, you’ll learn how to master this luxurious creation, from its signature components to essential cooking techniques and delightful variations that make it endlessly customizable for home cooks.
What is a Croque Madame?
A Croque Madame is a decadent French sandwich consisting of thick-cut toasted bread, layers of ham, cheese, and creamy béchamel sauce, topped with a fried or poached egg. The inclusion of the egg is what transforms the Croque Monsieur—its close relative—into a Croque Madame. The luscious yolk adds extra richness, creating a sandwich that is crisp on the outside and irresistibly gooey on the inside.
- Origin: France, popular in Parisian cafés since the early 20th century
- Main ingredients: Bread, ham, cheese (traditionally Gruyère or Comté), béchamel sauce, fried egg
- Difference from Croque Monsieur: The fried egg on top

Ingredients for the Ultimate Croque Madame
The beauty of this sandwich is that with careful selection of each component, you’ll achieve café-quality results at home. Here are the essentials:

Step-by-Step Guide: Making Croque Madame
Follow these steps to create a perfectly layered Croque Madame with crisp edges, luscious béchamel, and that signature runny egg.
1. Prepare the Béchamel Sauce
- Melt 2 tablespoons of unsalted butter in a small saucepan over medium heat.
- Whisk in 2 tablespoons of all-purpose flour, creating a smooth paste (roux). Cook, whisking often, for 1–2 minutes until pale and foamy but not browned.
- Gradually whisk in 1 cup of warm whole milk. Bring to a simmer, whisking constantly, until thickened—about 2–3 minutes.
- Season with salt, white pepper, and a pinch of ground nutmeg.
- Remove from heat and set aside, keeping warm.
2. Toast the Bread
- Preheat your broiler to low heat.
- Melt about 1 tablespoon of butter in a large skillet over medium-low heat.
- Add bread slices and toast until golden brown on the bottom, about 1–2 minutes.
- Add a little more butter, flip, and toast the second side.
3. Assemble the Sandwiches
- Spread a thin layer of mustard (if using) on half of the toasted slices.
- Top with folded slices of ham, add a generous spoonful of béchamel, and sprinkle with grated cheese.
- Cover with another slice of toasted bread, then spoon a little more béchamel and cheese on top.
4. Broil for a Bubbling Crust
- Transfer the assembled sandwiches onto a broiler-safe baking sheet.
- Place under the broiler (middle rack) for 3–4 minutes until the cheese is melted, browned, and bubbling.
5. Prepare the Fried Eggs
- While the sandwiches broil, heat a little butter in a nonstick skillet over medium heat.
- Crack one egg per sandwich and cook until the whites are set but the yolk is still runny. Season with salt and pepper.
6. Assemble and Garnish
- Top each sandwich with a fried egg.
- Garnish with chopped parsley and a sprinkle of sea salt.
- Slice in half and serve immediately, letting the egg yolk spill decadently over the sandwich.
Variations and Substitutions
- Cheese options: Substitute Jarlsberg, Beaufort, Swiss, or raclette for different flavors and melting profiles.
- Bread choices: Sourdough, white sandwich loaf, or boule are all excellent foundations.
- Mustard: Not every recipe includes it, but it adds a punchy tang and depth.
- Protein: For a twist, swap the ham with thinly sliced cooked chicken breast.
- Egg preparation: Try poached eggs for a slightly lighter take or skip the egg for a traditional Croque Monsieur.
Serving Suggestions
- Classic accompaniment: Serve with extra mustard and a side of sliced cornichons or pickles to balance the richness.
- Fresh salad: A peppery green salad (think arugula or frisée) dressed simply with lemon and olive oil offers refreshing contrast.
- Drinks pairing: Café au lait, sparkling cider, or a crisp French white wine work beautifully with this dish.
Expert Tips for a Perfect Croque Madame
- Make the béchamel sauce just before assembling to keep it spreadable and smooth.
- Use bread that’s at least a day old or lightly stale for optimal structure—it absorbs the sauce without getting soggy.
- Broil with care: keep a close eye to avoid burning the cheese topping.
- Season both the béchamel and the fried eggs generously to balance the sandwich’s richness.
- Cutting the sandwich before serving makes for dramatic presentation—allowing the golden yolk to flow.
Make-Ahead, Storage, and Reheating
- Best enjoyed fresh: The Croque Madame is at its peak crispness and gooeyness right after assembly.
- Refrigerate: You can cover and refrigerate assembled, but not yet broiled, sandwiches for up to 1 day before finishing under the broiler.
- Reheating: To reheat, place sandwiches (without egg) on a baking sheet in a 350°F oven for 4–6 minutes until warmed through. Add a freshly fried egg before serving.
- Freezing: Not recommended, as the textures will suffer.
Nutritional Information
The Croque Madame is an indulgent, filling meal. Its nutritional makeup depends on the size of the bread, the cut of ham, and generosity with cheese and sauce. Expect a main-dish serving to supply about:
- Calories: 600–850 per sandwich
- Protein: 30–40g (thanks to ham, cheese, and egg)

Troubleshooting & Common Questions
- Bread too soggy? Use firmer, thicker bread and don’t oversaturate with béchamel.
- Cheese not melting or browning? Raise the broiler rack or try a torch for the top.
- Eggs overcooked? Fry at medium-low heat just until the whites are set.
- Sandwich too salty? Choose low-sodium ham and season the béchamel lightly.
