The Ultimate Foot-Long Croque Monsieur: A Culinary Masterpiece

I’ll never forget the first time I tasted a truly exceptional Croque Monsieur. It was in a tiny Parisian bistro, tucked away on a cobblestone street. The aroma of melting Gruyère filled the air, mingling with the scent of freshly baked bread. One bite of that golden-brown, cheesy masterpiece, and I was hooked. The combination of savory ham, creamy béchamel, and nutty cheese was simply divine. Since then, I’ve been on a quest to perfect my own version, and this foot-long Croque Monsieur is the culmination of that journey – a truly impressive, crowd-pleasing take on a classic.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 20 minutes
• Total Time: 35 minutes
• Servings: 8
• Yield: 1 Foot-Long Sandwich
• Dietary Type: Not suitable for vegan/vegetarian, Contains gluten

Ingredients

• 1 1⁄4 cups milk
• 2 tablespoons unsalted butter
• 3 tablespoons flour
• 2 tablespoons thyme
• 1 loaf ciabatta (extra-long) or 1 loaf French bread (extra-long)
• 3 tablespoons mustard
• 3⁄4 lb deli ham
• 2 cups grated gruyere cheese
• 2 cups sharp cheddar cheese
• 1 cup grated parmesan cheese
• Salt and Pepper to taste

Equipment Needed

• Saucepan
• Whisk
• Baking sheet

Instructions

1. Begin by preheating your oven to 400 degrees F.
2. In a saucepan, heat the milk over medium heat for a few minutes until it’s hot. Be careful not to let it boil. You want it gently heated through.
3. In a separate saucepan, melt the butter over medium heat. Once melted, add the flour and whisk constantly to combine. Continue cooking for 2 minutes, stirring occasionally, to create a roux. This will help thicken your béchamel.
4. Add 1 tablespoon of the thyme to the roux, infusing it with herbal flavor. Slowly whisk in the hot milk to the roux, ensuring you break up any lumps as you go. This is crucial for a smooth béchamel.
5. Simmer the béchamel sauce for 2 more minutes while whisking constantly. The sauce should thicken slightly and become smooth and creamy. Remove from the heat and season with salt and pepper to taste. Remember to taste as you go and adjust seasoning as needed.
6. In a bowl, thoroughly mix together the gruyere cheese, sharp cheddar cheese, and parmesan cheese. This cheese blend will provide a rich and complex flavor profile.
7. Slice the loaf of ciabatta or French bread in half lengthwise. The quality of your bread will significantly impact the overall taste, so choose wisely.
8. Generously spread mustard on both cut sides of the bread. Layer the deli ham and half of the cheese mixture on the bottom half of the bread. Top with the other half of bread. Place the assembled sandwich on a baking sheet.
9. Place on a baking sheet and toast in the preheated oven until the cheese is melted. This will take approximately 5-10 minutes. Watch closely to prevent burning.
10. Preheat the broiler. Spread the béchamel sauce evenly on top of the sandwich. Sprinkle the leftover cheese mixture generously over the béchamel.
11. Broil until golden-brown and bubbly, about 6 minutes. Keep a close eye on the sandwich while broiling, as it can burn quickly. Rotate the baking sheet for even browning.
12. Garnish with the remaining tablespoon of thyme before serving.

Expert Tips & Tricks

• For an extra layer of flavor, consider adding a thin layer of Dijon mustard under the regular mustard.
• If your béchamel sauce is too thick, whisk in a little more milk until you reach the desired consistency. If it’s too thin, simmer it for a minute or two longer, whisking constantly.
• To prevent the bread from getting soggy, lightly toast the bread before adding the fillings.
• Don’t overcrowd the baking sheet. If necessary, bake in batches.
• For a richer béchamel, use whole milk or add a tablespoon of cream at the end.

Serving & Storage Suggestions

Serve the foot-long Croque Monsieur immediately while it’s hot and the cheese is melted and gooey. Cut it into individual portions for easy serving. Pair it with a simple green salad or a bowl of tomato soup for a complete meal.

Leftovers can be stored in the refrigerator for up to 2 days. To reheat, bake in a preheated oven at 350°F until heated through and the cheese is melted again. Reheating in a skillet or toaster oven can also work, but watch carefully to prevent burning. Microwaving is not recommended, as it can make the bread soggy. It is not recommended to freeze this sandwich, as the texture of the béchamel will change.
