Ingredients

For the Mashed Yams topping

  • 3 medium Japanese yams (around 3 pounds) peeled and chopped into 1” cubes
  • 1 tablespoon ghee or grass-fed butter
  • 150 ml chicken stock
  • kosher salt to taste

For the Meat Filling

  • 1 tablespoon avocado oil
  • 2 pounds ground lamb
  • 2 celery stalks diced
  • 1 medium onion diced
  • 1 medium carrot diced
  • Kosher salt to taste
  • 8 ounces cremini mushrooms roughly chopped
  • 1 medium zucchini diced
  • 5-6 cloves garlic roughly chopped
  • 1 tablespoon smoked paprika
  • 1 tablespoon sweet paprika
  • 1 tablespoon granulated onion
  • 500 ml chicken stock
  • 1/2 teaspoon freshly-cracked black pepper plus more to taste
  • ½ cup fresh parsley – finely chopped

Instructions

For the Mashed Yams Topping

  • Preheat the oven or Traeger grill to 400F.
  • Bring a large pot of water to a boil. Season with a 2 teaspoons salt and add the yams. Cook until completely fork-tender, 12 to 15 minutes. Drain the yams, reserving 1/4 cup of the cooking water. Add the ghee and salt and mash until smooth using a potato masher. Add the chicken stock a little bit at a time, mashing it into the yams as you go, until they are smooth yet slightly chunky. Taste for seasoning, adjust with salt as desired and set aside.

For the Meat Filling

  • Remove lamb from fridge 1 hour before cooking and let come to room temperature. Pat the meat very dry with paper towel and form into large ball shapes. This will help with the browning process.
  • Heat a large skillet or sauté pan over medium-high heat. Add avocado oil and heat until shimmering. Add the ground lamb and cook until browned, around 5 minutes. Flip and brown the bottom sides, around 4 minutes. Reserving the fat in the pot, transfer the lamb meatballs to a bowl and set aside.
  • Lower the heat to medium. Add the celery, carrot and onion and season with a pinch of salt. Cook, stirring regularly, until the onion is soft and translucent, around 5 minutes. Add the mushrooms and cook, stirring regularly, until they have softened, around 7 minutes. Add the zucchini and garlic and cook, stirring, until the zucchini has slightly softened, around 5 minutes.
  • Add the smoked paprika, sweet paprika, and onion powder. Cook, stirring to combine, until spices are fragrant, around 60 seconds. Return the browned lamb to the pot and stir to coat. Add the chicken stock and season with pepper and 1 teaspoon salt. Raise the heat to medium-high and bring to a steady simmer. Cook, uncovered, stirring occasionally, until the liquid has reduced by half, around 12 minutes.
  • Taste the filling for seasoning and adjust with salt and pepper as desired. Remove from heat, add the parsley and stir through. Transfer filling to a casserole dish, if using. Otherwise, leave it in the skillet and spoon the mashed yams topping over top and spread it out with a spoon.
  • Place the shepherd's pie on a baking sheet to catch any spill over from the juices and cook until the yams are golden brown and the gravy is bubbling, around 25 minutes. Remove from oven and let cool 15 minutes before serving.
