This Herb-Infused Shepherd’s Pie with Sweet Potato Mash is a comforting twist on a classic dish. With a fragrant blend of herbs and the natural sweetness of sweet potatoes, it’s perfect for cozy dinners or a hearty meal any time of year.
Olive oil kicks off the cooking by providing a smooth base for sautéing. Ground beef forms the hearty core of the dish, absorbing all the flavors. Onion and garlic add depth and aromatic richness. The carrots, peas, and corn kernels bring sweetness and texture, brightening up the filling. Tomato paste and beef broth create a savory sauce that binds everything together, while Worcestershire sauce gives it a tangy kick. The herbs, thyme and rosemary, infuse the beef with earthy notes. For the topping, sweet potatoes are mashed with milk, butter, and a hint of nutmeg for a creamy, slightly spiced finish.
This dish is hearty enough on its own, but a crisp green salad with a tangy vinaigrette pairs perfectly to balance the rich flavors. A side of crusty bread can also be a nice touch for soaking up any extra sauce.
Start by preheating your oven to 375°F. While that warms up, grab a large skillet and heat the olive oil over medium heat. Toss in the diced onion and minced garlic, stirring them around until they turn translucent. This usually takes about 3-4 minutes.
Next, add the ground beef and cook it until it’s browned. Be sure to break it up with a spatula so it cooks evenly. Once browned, it’s time to bring in the veggies. Stir in the carrots, peas, and corn kernels, letting them mingle with the beef.
Now, add the tomato paste and give it a good stir, followed by the beef broth and Worcestershire sauce. Sprinkle in the thyme, rosemary, and season with salt and pepper. Let this mixture simmer away for about 10 minutes until it thickens slightly.
While your beef filling is simmering, get a pot of water boiling and cook the sweet potatoes until they’re tender—about 15 minutes should do it. Once they’re soft, drain and return them to the pot. Mash them up with the milk, butter, and a dash of nutmeg. Season with salt and pepper to your liking.
Transfer the beef mixture into a baking dish, spreading it out evenly. Dollop the sweet potato mash on top and smooth it out with a spatula. Pop the dish into your preheated oven and bake for 25 minutes, until the top is golden brown and inviting.
