🥘 Ingredients

11 items

• 2 tablespoons unsalted butter
• 2 tablespoons all-purpose flour
• 1 cup whole milk
• 1 teaspoon Dijon mustard
• 0.25 teaspoon salt
• 0.25 teaspoon ground black pepper

• 4 ham slices
• 2 teaspoons olive oil or more butter for toasting

📝 Instructions

12 steps

1. Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.

2. In a small saucepan over medium heat, melt 2 tablespoons of unsalted butter. Once melted, whisk in 2 tablespoons of all-purpose flour to form a roux. Cook the roux for 1-2 minutes, stirring constantly, until golden and bubbly.

3. Gradually pour in 1 cup of whole milk while whisking to prevent lumps. Continue cooking over medium heat, whisking frequently, until the béchamel sauce thickens (about 3-4 minutes).

4. Stir in 1 teaspoon of Dijon mustard, 1/4 teaspoon of salt, 1/4 teaspoon of ground black pepper, and a pinch of ground nutmeg. Remove from heat and mix in 1/4 cup of shredded Gruyère cheese until melted and smooth.

5. Toast 4 slices of sandwich bread lightly in a toaster or under a broiler, being careful not to let them burn.

6. Spread a thin layer of béchamel sauce on two slices of bread. Add two slices of ham to each of the prepared slices, then sprinkle a layer (about 1/4 cup) of shredded Gruyère cheese over the ham.

7. Top each sandwich with the remaining slices of bread. Spread a little olive oil or softened butter over the tops of the sandwiches.

8. Heat a large skillet over medium heat and add 1 teaspoon of olive oil or butter. Place the sandwiches into the skillet, pressing them lightly with a spatula, and cook until the bottom is golden brown (about 2-3 minutes).

9. Flip the sandwiches and cook the other side until golden brown and the cheese inside begins to melt (about 2-3 minutes).

10. Remove the sandwiches from the skillet and place them on the prepared baking sheet. Spread a generous layer of béchamel sauce over the top of each sandwich and sprinkle the remaining shredded Gruyère cheese evenly over both sandwiches.

11. Bake the sandwiches in the preheated oven for 5-7 minutes, or until the cheese on top is melted and bubbling. For a golden brown finish, broil for an additional 1-2 minutes, if desired.

12. Remove from the oven and let the sandwiches rest for 1-2 minutes. Slice each Croque Monsieur in half and serve warm.
