• 1½ tbsp all-purpose flour
• ¼ tsp kosher salt
• A pinch of white pepper
• ⅛ tsp freshly ground nutmeg

For the Sandwich

Step-by-Step: How to Make Croque Monsieur

1. Prep & Preheat

• Preheat your oven to 200 °C (390 °F) or 180 °C if using a fan-assisted setting.

2. Make the Béchamel Sauce

a. In a medium saucepan, gently heat the milk and cream until they begin to steam—avoid bringing them to a boil.
b. In another small saucepan, melt butter over medium-low heat. Stir in flour and cook for 3 minutes, stirring constantly to avoid browning.
c. Gradually pour in half the hot milk, whisking until smooth, then stir in the remainder along with nutmeg, salt, and white pepper.
d. Cook, stirring for 30–60 seconds, until the mixture thickens to a spreadable, butter-like consistency. If any lumps remain, whisk until smooth. Remove from heat and let cool slightly.

3. Assemble the Sandwiches

a. Generously spread half of the béchamel sauce over each of the four slices of bread.
b. On two slices, layer 2 cheese slices, folded to cover fully.
c. Spread 1 tsp Dijon mustard over the cheese.
d. Add the ham, then another 1 tsp Dijon.
e. Top with 2 more cheese slices, folded to fit.
f. Close each sandwich.

4. Pan-Fry to Golden

• In a skillet over medium–medium-high heat, melt the butter.
• Place sandwiches in the pan and press down with a spatula.
• Cook for 2 minutes per side until a deep golden-brown crust forms.
• Transfer to a baking tray.

5. Bake & Broil

a. Spread the remaining béchamel evenly on top of each sandwich.
b. Sprinkle with shredded Gruyère and Parmesan.
c. Start by baking, then switch to the broiler for 2–4 minutes until the cheese is golden and bubbly.

6. Serve Immediately

• Transfer sandwiches to pre-warmed plates.
• Serve with utensils (it’s deliciously messy!).
• Serve alongside crispy fries and a lightly dressed green salad for an authentic bistro-style meal.

Helpful Tips

• Avoid overheating the milk or cream, as excessive heat may cause them to curdle or separate.
• Maintain medium heat when making the roux; too hot and it browns, too cool and lumps form.
• Proper thickness matters: béchamel that’s too thick won’t spread well, too thin drips off.
• Use real dairy—milk and cream create richness; non-dairy substitutes won’t achieve the same result.
• Press gently when frying; it encourages even browning without flattening the sandwich too much.
• Keep an eye during broiling—cheese browns quickly, so work in short intervals under the broiler.

Substitutions And Variations

• Bread: Ciabatta, pane di casa, or lightly toasted soft bread works.
• Cheese: Replace with Comté, Emmental, cheddar, Monterey Jack, or tasty cheese. Avoid mozzarella—it lacks strong flavor.
• Ham: Swap in thick-cut prosciutto, Black Forest ham, or smoked turkey.
• Add-ins: Try caramelized onions, sliced tomato, or sautéed mushrooms.
• Vegetarian option: Replace ham with grilled zucchini or roasted red pepper slices.
• Green alternative: Use a spinach–béchamel sauce in place of Dijon for a creamier flavor twist.

Storage Instructions

• Prep ahead: Assemble sandwiches, wrap tightly in cling film, and freeze for up to 2–3 months.
• To cook: Thaw in the refrigerator, then follow the fry, bake, and broil steps as directed.
• Leftovers: To store, place leftovers in an airtight container in the fridge for up to two days. Reheat in a low-temperature oven (around 160 °C/325 °F) and broil briefly to re-crisp the topping.
• Béchamel: Store unused sauce in an airtight jar in the fridge for up to 3 days. Reheat gently, whisking in a splash of milk to restore smoothness.

Frequently Asked Questions About Croque Monsieur

1. Can I make this vegetarian?
Absolutely! Leave out the ham and add fillings like sautéed mushrooms, roasted red peppers, or even pesto for flavor. Load up with cheeses and béchamel—still indulgent, still delicious.

2. Is there a low-fat or lighter version?
Yes! Swap heavy cream for extra milk or a lower-fat milk, use less cheese, and grill instead of frying. You’ll lose some creaminess, but it’s still a tasty compromise.

3. How do I get that perfect cheese crust on top?
Use enough cheese for a thick layer (about ½ cup Gruyère + 3 Tbsp Parmesan). Start by baking, then switch to the broiler for 2–4 minutes until bubbling and golden. Keep a close eye to avoid burning.

4. Can I prepare these sandwiches in advance for a group?
Definitely! Assemble and wrap sandwiches in cling film, then freeze up to 2–3 months. Thaw, then fry + bake as usual. Great prep for parties or meal planning.

5. What bread is best?
Pick something sturdy—sourdough, ciabatta, or pane di casa. If your bread is soft, toast lightly first or sandwich two slices with cheese “glued” in between for extra structure.
