# Steps:

01 - Preheat oven to 400°F.
02 - Place sweet potatoes in a large saucepan, cover with water, and bring to a boil. Simmer for 15–20 minutes until tender.
03 - While the sweet potatoes cook, heat olive oil in a large skillet over medium heat. Add onion and carrot; sauté for 5 minutes until softened.
04 - Add garlic and mushrooms; cook for another 3–4 minutes until the mushrooms release their juices.
05 - Add ground beef, breaking it up with a spoon, and cook until browned.
06 - Stir in tomato paste, diced tomatoes, Worcestershire sauce, thyme, rosemary, salt, and pepper. Pour in beef stock and mix well. Simmer uncovered for 15 minutes, stirring occasionally, until thickened.
07 - Drain the sweet potatoes and mash with butter, milk, salt, and pepper until smooth and creamy.
08 - Spoon the beef filling into a 9x9 inch baking dish. Spread the sweet potato mash evenly on top.
09 - Bake for 20–25 minutes until the top is slightly golden and the filling is bubbling.
10 - Let rest for 10 minutes before serving.

# Expert Advice:

01 -
  • The sweet potato adds natural sweetness that balances the tangy tomatoes and earthy mushrooms
  • Everything cooks in one pan before baking, meaning less cleanup and more flavor development
  • It reheats beautifully and actually tastes better the next day as the flavors meld together
02 -
  • The sweet potato mash spreads more easily when its still warm, so time your mashing to finish when the filling is ready
  • Do not skip simmering the filling uncovered, or you will end up with a watery pie instead of a rich, cohesive one
  • Letting the pie rest before serving is essential or it will slide apart when you scoop it
03 -
  • Grate a little nutmeg into the sweet potato mash for a warm, subtle depth that surprises people
  • Deglaze the beef pan with a splash of red wine before adding the stock for even more complexity
