Ingredients Equipment Method Notes

Ingredients
  

  • 4 boneless, skinless chicken breasts about 1.5 lbs total
  • 8 slices thinly sliced deli ham e.g., Black Forest or smoked ham
  • 4 slices Swiss cheese
  • 1/2 cup milk or half-and-half
  • 2 tablespoons Dijon mustard
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon black pepper, to taste
  • 1/2 cup Panko breadcrumbs
  • 2 tablespoons salted butter

Equipment

  • Slow Cooker (6-quart or larger)
  • Small skillet
  • Whisk
  • Meat thermometer
  • Measuring cups and spoons
  • Small bowl

Method
 

  1. Step 1: Prepare the Sauce. In the bottom of your slow cooker insert, whisk together the cream of chicken soup, milk, Dijon mustard, garlic powder, onion powder, and black pepper until smooth and well combined.
  2. Step 2: Layer the Ingredients. Place the chicken breasts directly into the sauce in a single layer. Spoon some of the sauce over the top of each piece. Lay two slices of deli ham over each chicken breast, followed by one slice of Swiss cheese on top of the ham.
  3. Step 3: Slow Cook to Perfection. Cover the Crockpot and cook on LOW for 4 to 6 hours or on HIGH for 2 to 3 hours. The chicken is done when it is cooked through and reaches an internal temperature of 165°F (74°C).
  4. Step 4: Toast the Topping. About 10 minutes before serving, melt the butter in a small skillet over medium heat. Add the Panko breadcrumbs and stir constantly until they are fragrant and golden brown. Remove from heat immediately to prevent burning.
  5. Step 5: Garnish and Serve. Carefully place each chicken breast on a serving plate. Spoon a generous amount of the creamy sauce from the Crockpot over the top, and then sprinkle with the toasted Panko breadcrumbs. Serve immediately.

Notes

Expert Tips: For the juiciest chicken, use a meat thermometer and start checking for doneness at the lower end of the cook time. The toasted Panko topping is crucial for providing the classic Cordon Bleu crunch. If the sauce is too thin, thicken it by stirring in a slurry of 1 tablespoon of cornstarch mixed with 2 tablespoons of cold water during the last 30 minutes of cooking.
Variations & Substitutions: Provolone or Gruyère can be used instead of Swiss cheese. Prosciutto can replace the deli ham. For a different flavor, try cream of mushroom or celery soup. If you're out of Panko, crushed Ritz crackers work well. For extra flavor, add sautéed mushrooms or a pinch of cayenne pepper to the sauce.
