# How to Make It:

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 baking dish (about 9x9 in). 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 topping adds natural sweetness that cuts through the savory beef filling
  • Everything cooks in one skillet plus one pot, meaning less cleanup and more eating
  • This reheats beautifully for lunch the next day, if there is any left
02 -
  • The filling needs to be thick before it goes into the dish, or you will end up with soupy cottage pie instead of the hearty consistency you want
  • Let the assembled pie rest for 10 minutes after baking, otherwise the filling will slide everywhere when you try to serve it
03 -
  • Sprinkle grated sharp cheddar over the sweet potato topping during the last 5 minutes of baking for an extra layer of flavor
  • Use a fork to create ridges in the sweet potato topping before baking, which creates more crispy golden edges
