2 ¼ cups beef stock - beef broth or beef bouillon, 530ml

Instructions
- Preheat the oven to 350°F / 175°C (180°C fan-forced).
- Peel and cube the sweet potatoes into roughly 1-inch (2.5cm) pieces. Place them in a large saucepan, cover with cold water, and bring to a boil over high heat. Reduce to a simmer and cook for 15–18 minutes until fork-tender. Drain thoroughly.2 pounds sweet potato
- Return the drained sweet potatoes to the warm saucepan and mash until smooth using a potato masher.2 pounds sweet potato
- Add the margarine, white pepper, and salt and black pepper to taste. Mix in 1 tablespoon of warm beef stock to loosen the mash — it should be smooth and spreadable but still hold its shape.3 tablespoons margarine, 1 tablespoon beef stock, 1/4 teaspoon white pepper, 1 pinch salt
- Meanwhile, heat the olive oil in a large 12-inch (30cm) sauté pan over medium-high heat. Add the diced onion, diced carrots, and a generous pinch of salt. Sauté for 5–6 minutes until the vegetables are softened.1 tablespoon olive oil, 1 medium yellow onion, 3 medium carrots, 1 pinch salt
- Add the ground beef to the pan and break it up with a wooden spoon. Cook for 7–8 minutes, stirring occasionally, until no pink remains and the meat is well browned.2 pounds ground beef
- Add the minced garlic and stir for 1 minute until fragrant. Add the tomato paste and stir thoroughly until it coats the meat evenly, about 1 minute. Sprinkle the flour over the mixture and stir until all the flour is fully absorbed — no dry patches should remain. Pour in the beef stock and add the fresh oregano and thyme. Stir well and let the gravy simmer for 2–3 minutes until it thickens noticeably.3 cloves garlic, 6 ounces tomato paste, 1/4 cup all purpose flour (plain flour Australia and UK), 2 1/4 cups beef stock, 1 teaspoon oregano, 1 teaspoon thyme
- Reduce the heat to low and stir in the frozen corn and peas. Cook for 2 minutes until warmed through. Remove from heat.1 cup corn, 1 cup peas
- Transfer the beef and vegetable filling into a 9x13 inch (33x23cm) baking dish and spread it into an even layer.
- Dollop small spoonfuls of the sweet potato mash across the top of the filling. Using a silicone spatula, gently spread the mash into an even layer, working from the edges inward to create a seal. Place the baking dish on a baking sheet to catch any drips.
- Bake at 350°F / 175°C (180°C fan-forced) for 25–30 minutes until the filling is bubbling at the edges and the sweet potato top is lightly golden.
- Let the pie rest for 5–10 minutes before serving — this allows the filling to set so it holds together when scooped.
Notes
Storage: Refrigerate leftovers covered for up to 3 days. Reheat individual portions covered in the microwave at medium power to keep the mash from drying out.
Freezer-friendly: Cool completely, portion into airtight containers, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
Make-ahead: Assemble the full dish up to 2 days ahead, cover tightly, and refrigerate. Let it sit out while the oven preheats and add 10 minutes to the bake time.
Substitution: Swap margarine for unsalted butter for a richer mash, or use olive oil to keep it dairy-free.
Pro tip: Stir the tomato paste into the browned beef before adding the flour — this coats the meat in fat first so the flour thickens evenly into a smooth gravy with no lumps.
