Ingredients

Filling Ingredients

  • 1 pound ground beef or lamb
  • 2 medium carrots, peeled and diced
  • 1 small green pepper, diced
  • 1 small yellow onion, diced
  • 1 cup mushrooms, cleaned and stemmed, diced
  • 4 cloves garlic, minced
  • 3 ounces tomato paste
  • 1 teaspoon chili powder
  • 1/2 teaspoon dried rosemary or dried herb of choice
  • 1/2 teaspoon fine salt or to taste
  • 1/4 teaspoon black pepper
  • 1/4 cup water

Topping Ingredients

  • 2 large sweet potatoes (about 12 ounces each), peeled and cubed (~6 cups cubed)
  • 1 tablespoon butter (may substitute ghee or coconut oil for Whole30)
  • 1/2 teaspoon chili powder
  • 1/4 teaspoon fine salt

Instructions

  1. Preheat the Oven. Set your oven to 375℉ (190℃) to prepare for baking the assembled shepherd's pie in the final step.
  2. Cook the Sweet Potatoes. Place the peeled and cubed sweet potatoes in a steamer basket inside a pot of boiling water and steam until tender, about 15 minutes. Alternatively, bake whole sweet potatoes until fork tender, approximately 45 to 60 minutes.
  3. Sauté the Filling. In a medium skillet over medium-high heat, cook the ground beef or lamb along with diced carrots, green pepper, onion, mushrooms, and minced garlic. Continue stirring and cooking until the carrots soften, about 12-15 minutes.
  4. Prepare the Sweet Potato Topping. While the filling cooks, add the steamed or baked sweet potatoes along with butter, chili powder, and salt into a food processor or blender. Process until you achieve a smooth, creamy mash.
  5. Season the Filling. Once the carrots are tender, stir the tomato paste, chili powder, dried rosemary, salt, black pepper, and water into the meat and vegetable mixture. Let it combine well for the flavors to meld.
  6. Assemble the Pie. If you started cooking the filling in an oven-safe 10-inch cast-iron skillet, you can top it directly with the sweet potato mash. Otherwise, transfer the filling to a casserole or 9×9 inch baking dish. Spread the sweet potato topping evenly over the filling and sprinkle a bit of sea salt and chili powder on top for extra flavor.
  7. Bake the Shepherd's Pie. Place the assembled dish in the preheated oven and bake for 10 minutes. This step warms the pie thoroughly and helps the topping set slightly.
  8. Serve. Remove from the oven and serve hot for a comforting meal that blends savory filling and sweet mashed potato topping.

Notes

  • For Whole30 compliance, substitute butter in the topping with ghee or coconut oil.
  • If using white potatoes instead of sweet potatoes, mash them by hand to avoid a pasty texture.
  • Steaming sweet potatoes is faster, but baking gives them a richer flavor.
  • This recipe can be made with ground lamb or beef depending on preference.
  • Adjust chili powder to taste if you prefer a milder or spicier pie.
  • Use fresh herbs if available, replacing dried rosemary for an enhanced aroma.
