  • Ready In

  1. Preheat oven to 425 degrees F (220 degrees C). Line a baking sheet with heavy-duty aluminum foil.
  2. Combine bread crumbs and 1 teaspoon melted butter in a small bowl.
  3. Melt 2 tablespoons butter in a saucepan over medium heat. Cook and stir ham and onion in melted butter until onion turns translucent, about 5 minutes. Stir in thyme and cook for 1 minute. Add flour and cook, stirring constantly, until flour has lost its raw smell, about 3 minutes. Remove from heat and pour in 1/2 cup plus 1 tablespoon milk. Place saucepan back over medium heat and cook, stirring constantly, until sauce is thick, 1 to 2 minutes.
  4. Remove saucepan from heat and add 1/2 cup shredded Gruyere cheese, Dijon mustard, salt, black pepper, cayenne pepper, and nutmeg. Stir to combine.
  5. Stir chicken and diced pickle into cheese sauce.
  6. Place toasted bread slices on the prepared baking sheet. Brush one side of each bread slice with 3/4 teaspoon melted butter. Turn slices over and top each with 1/4 of the cheese sauce. Sprinkle 1 tablespoon shredded Gruyere cheese over the top of each sandwich. Top with bread crumb mixture.
  7. Bake sandwiches in the preheated oven until cheese is bubbling and chicken mixture is hot, 15 to 20 minutes.

I made this just as directed by Chef John, and everyone loved them. They made the perfect lunch for us as we greeted out-of-town visitors. I did think that they were just a tad on the bland si...

I followed the recipe to as written...delicious!!! Couldn't find Gruyere cheese at my small town grocery store, so just used Swiss.

Really good as is, but next time maybe I'll add some hot sauce to bring it to a sharper taste.

I made this dish last night, it was absolutely delicious! My son devoured almost eight inches worth of the entire loaf. Thanks for sharing??

Great recipe! We loved the simplicity of the recipe whilst incorporating all of our favourite chicken cordon bleu flavours. We will definitely make this again.

Friday nights before Scout camp-outs are always rushed and I'm constantly looking for quick Grab and Go hand foods that still pack some substance. I used 6" French Rolls from the bakery and doub...
