Ingredients

  • 23 cups cooked chicken breast or thigh, shredded or chopped
  • 1½ cups sliced mushrooms (cremini or button)
  • 1 small onion, chopped
  • 2 cloves garlic, minced
  • 2 tablespoons butter or olive oil
  • 2 tablespoons all-purpose flour
  • 1 cup chicken broth
  • ½ cup heavy cream
  • 1 teaspoon fresh thyme or chopped parsley
  • Salt and pepper, to taste
  • 2 pounds potatoes, peeled and chopped
  • 3 tablespoons butter
  • 2 egg yolks
  • ¼ cup heavy cream or milk
  • Pinch of nutmeg (optional)
  • Salt and pepper, to taste

Instructions

  1. Boil potatoes until tender. Drain and mash until smooth.

  3. In a skillet, sauté onion and garlic in butter until soft.
  4. Add mushrooms and cook until golden.
  5. Stir in flour and cook 1 minute.
  6. Slowly whisk in broth and cream. Simmer until thickened.
  7. Stir in cooked chicken, thyme or parsley, salt, and pepper.
  8. Spoon the filling into a greased baking dish.
  9. Pipe duchess potatoes on top, covering the filling completely.
  10. Bake at 400°F (200°C) for 20–25 minutes, until golden and lightly crisped on top.
  11. Let rest 5–10 minutes before serving.

Notes

  • Add grated Parmesan or Gruyère to the potatoes for extra flavor.
  • Use rotisserie chicken to save time.
  • Leeks can replace onions for a milder taste.
  • Milk can replace cream for a lighter version.
  • For a rustic look, spoon and swirl the potatoes instead of piping.
