Ingredients

For Ham Roses – Optional

  • 2 slices French ham (or smoked ham)
  • 6 parsley leaves (for garnish)

For Béchamel Sauce

  • 2 tbsp unsalted butter
  • 2 tbsp all-purpose flour
  • 6 oz (170 mL) whole milk
  • 2 tsp Dijon mustard
  • Nutmeg, a nice sprinkle
  • Salt, a nice sprinkle
  • Pepper, a nice sprinkle

For Croque Monsieur

  • ½ baguette (12 slices, about ½ inch each)
  • 6 slices French ham (or smoked ham)
  • 4 oz (113 g) Gruyere cheese (or Emmental cheese)

Instructions

  1. Prepare Ham Roses – Optional: Slice one piece of ham into ½ inch slices and another piece into ¼ inch slices. Carefully roll the ½ inch slices into a rose shape, then wrap the ¼ inch slices around the outside to complete the rose. Place the prepared ham roses in a container and refrigerate until ready to serve.
  2. Make the Béchamel Sauce: Heat a saucepan over low-medium heat and melt 2 tbsp unsalted butter. Add 2 tbsp flour and whisk together to form a roux. Gradually add 6 oz (170 mL) whole milk while whisking continuously to avoid lumps. Cook and whisk until the sauce thickens, about 3-5 minutes. Remove from heat and stir in 2 tsp Dijon mustard, a sprinkle of nutmeg, salt, and pepper. Set aside.
  3. Assemble Croque Monsieur: Preheat the oven to 425°F (220°C). Slice the baguette into 12 slices, about ½ inch thick. Place them on a foil or parchment-lined baking sheet. Spread a generous layer of béchamel sauce over each baguette slice.
  4. Prepare Ham and Cheese: Fold each ham slice in half and use a piece of baguette to cut the ham to the perfect size that fits the bread slices. Repeat for 6 ham slices. Arrange the cut ham pieces on top of 6 bread slices. Thinly slice the Gruyere cheese into ¼ inch slices and place 2 slices on each ham-covered bread slice.
  5. Finish Assembly: Place the remaining 6 slices of bread on top, béchamel side down, creating sandwiches. Coat the top of each sandwich with a thin layer of béchamel sauce. Add a few more slices of Gruyere cheese on top for extra cheesiness.
  6. Bake the Croque Monsieur: Place the baking sheet on the bottom oven rack and bake at 425°F (220°C) for 5-7 minutes. Then move the baking sheet to the top rack and increase the oven temperature to 450°F (230°C). Bake for an additional 2-3 minutes until the cheese bubbles and browns. Watch carefully to prevent the sandwich tops from slipping off due to cheese melting rapidly.
  7. Serve: Remove from the oven, garnish with ham roses and parsley leaves, and serve immediately while hot and cheesy.

Notes

  • Make sure the tops don’t slip off when increasing the oven temperature and moving the baking sheet to the top rack by watching through the oven window carefully.
  • The optional ham roses add an elegant garnish that elevates presentation but can be omitted if desired.
  • Use a good-quality Gruyere or Emmental cheese for authentic flavor and excellent melting properties.
  • Béchamel sauce thickness is crucial – whisk continuously to avoid lumps and ensure smooth consistency.
  • Adjust seasoning in the béchamel to taste before assembling sandwiches.
