Mini Smoked Salmon Sandwiches (Croque-Monsieur)

There’s something undeniably comforting about a warm, cheesy sandwich, especially on a chilly afternoon. My grandmother used to make the most incredible Croque-Monsieur, the classic French ham and cheese sandwich, but her version always felt a bit heavy for my taste. One day, experimenting in my own kitchen, I decided to lighten things up by swapping the ham for delicate smoked salmon. The result? Pure bliss. These mini versions are perfect for parties, brunches, or even a sophisticated snack.

Recipe Overview

• Cook Time: 20 minutes
• Total Time: 50 minutes
• Servings: 20
• Dietary Type: N/A

Ingredients

• 1/2 cup unsalted butter
• 3 tablespoons all-purpose flour
• 2 cups milk
• 10 ounces thinly sliced smoked salmon, coarsely chopped
• 1 1/2 cups Gruyere cheese (6 oz.), shredded
• 1 cup minced fresh chives
• 1/2 teaspoon grated fresh nutmeg
• Salt and freshly ground black pepper to taste
• 40 slices rye cocktail bread
• 40 slices pumpernickel rounds
• 6 large eggs

Equipment Needed

• Medium saucepan
• Whisk
• Large shallow bowl
• Large skillet
• Large rimmed baking sheets (2-3)
• Small wooden forks or skewers

Instructions

1. Begin by preparing the salmon béchamel sauce. In a medium saucepan, melt 3 tablespoons of butter over medium heat. Once melted, whisk in the 3 tablespoons of all-purpose flour until completely blended, creating a roux. Cook the roux over moderately high heat, stirring constantly, until it turns a light golden brown, this should take about 3 minutes.

2. Gradually whisk in the 2 cups of milk until the mixture is smooth and free of any lumps. Bring the sauce to a boil, whisking continuously to prevent scorching. Once boiling, reduce the heat to moderately low and simmer the sauce, whisking often, until it has thickened and no floury taste remains, approximately 5 minutes.

3. Remove the saucepan from the heat and allow the sauce to cool slightly, stirring occasionally, until it is very warm but not scalding.

4. Stir in the 10 ounces of coarsely chopped smoked salmon, 1 1/2 cups of Gruyere cheese, 1 cup of minced fresh chives, and 1/2 teaspoon of grated fresh nutmeg into the warm sauce. Season the mixture generously with salt and freshly ground black pepper to taste. Allow the salmon béchamel sauce to cool completely. This is crucial to prevent the bread from becoming soggy later.

5. Once the salmon mixture has cooled, it’s time to assemble the mini sandwiches. Spread half of the rye cocktail bread slices with a rounded tablespoon of the salmon mixture. Top each with another slice of rye bread, creating the sandwiches. Repeat the process with the pumpernickel rounds and the remaining salmon mixture.

6. At this stage, the sandwiches can be covered tightly with plastic wrap and stored in the refrigerator overnight if you’re preparing them in advance.

7. Preheat your oven to 400°F (200°C). Prepare a breading station. In a large shallow bowl, thoroughly beat the 6 eggs until they are well combined. Stack 2 or 3 large rimmed baking sheets on one side of your stovetop to have them ready for the next step.

8. In a large skillet, melt 1 tablespoon of butter over moderate heat. While the butter is melting, dip 8 of the sandwiches into the beaten egg, ensuring they are completely coated on all sides.

9. Cook the egg-dipped sandwiches in the skillet over moderately high heat, turning once, until they are golden brown, about 1 minute per side. The browning adds a wonderful texture and flavor.

10. Transfer the browned sandwiches to one of the prepared baking sheets, leaving a small space between each one to allow for even heating. Repeat the process with the remaining sandwiches and beaten eggs, using 1 tablespoon of butter per batch to ensure each batch is nicely browned.

11. Reheat the sandwiches in the preheated oven for about 8 minutes, or until they are piping hot and the cheese is melted and bubbly. This step ensures the filling is thoroughly heated and the sandwiches are irresistibly gooey.

12. Remove the baking sheets from the oven and allow the sandwiches to cool slightly before serving. Cut each sandwich in half on the diagonal to create attractive triangles. Skewer each triangle with a small wooden fork or skewer for easy handling. Serve immediately while hot.

Expert Tips & Tricks

• For a richer flavor, use a high-quality Gruyere cheese. Emmental or Jarlsberg can also be substituted.
• Don’t skip the step of cooling the salmon mixture completely before assembling the sandwiches. This prevents soggy bread and ensures a better texture.
• If you’re short on time, you can use pre-made béchamel sauce as a base. Just be sure to adjust the seasoning to your liking.
• To prevent the sandwiches from sticking to the skillet, ensure the butter is fully melted and the skillet is properly heated before adding the egg-dipped sandwiches.
• For an extra touch of elegance, garnish the sandwiches with a sprig of fresh dill or a sprinkle of paprika before serving.

Serving & Storage Suggestions

Serve these Mini Smoked Salmon Sandwiches hot as an appetizer, brunch item, or party snack. They pair well with a crisp white wine like Sauvignon Blanc or a light sparkling wine.

Leftover sandwiches can be stored in an airtight container in the refrigerator for up to 2 days. Reheat them in a preheated oven at 350°F (175°C) for about 5-7 minutes, or until heated through. Microwaving is not recommended as it can make the bread soggy.
