Recipe Instructions
Step 1
Combine bread crumbs and 1 teaspoon melted butter in a small bowl.
Step 2
Preheat the oven to 425 degrees F (220 degrees C). Line a baking sheet with heavy-duty aluminum foil.
Step 3
Melt 2 tablespoons butter in a saucepan over medium heat. Add ham and onion; cook until onion turns translucent, about 5 minutes. Stir in thyme; cook for 1 minute. Add flour; cook, stirring constantly, until flour smells nutty, about 3 minutes. Off heat, add 1/2 cup plus 1 tablespoon milk. Return saucepan to medium heat; cook, stirring constantly, until sauce thickens, 1 to 2 minutes.
Step 4
Off heat, add 1/2 cup Gruyère cheese, Dijon, cayenne pepper, nutmeg, salt, and black pepper; stir to combine. Fold in chicken and pickle.
Step 5
Place toasted bread slices on the prepared baking sheet; divide and brush one side of each slice with remaining 1 tablespoon melted butter. Flip slices; top each with 1/4 chicken mixture. Divide and sprinkle remaining 1/4 cup Gruyère cheese over sandwiches; top with bread crumb mixture.
Step 6
Bake in the preheated oven until cheese is bubbling and chicken mixture is hot, 15 to 20 minutes.
