- 1/2 tsp black pepper: gives a gentle spice to round out the savory layers.
- 50 ml milk: combined with butter to create a silky mash topping.

How To Make Sweet Potato and Lentil Shepherd’s Pie
Bringing this dish together is a joy—first you’ll cook and mash the sweet potatoes until velvety, then build a richly seasoned lentil filling with aromatic veggies and herbs. Once both components are ready, you’ll layer them in a baking dish and let the oven work its magic, turning the top golden and bubbly.
1. Preheat your oven to 200°C (400°F) to ensure it’s at the perfect temperature for a golden crust and bubbling edges.
2. Peel and chop the sweet potatoes into chunks, add them to a pot of boiling salted water, and cook until fork-tender, about 15 minutes.
3. Drain the sweet potatoes, return them to the pot, then mash with 25 g butter and 50 ml milk; season with 1 tsp salt and ½ tsp black pepper, then set aside.
4. While the potatoes cook, heat 1 tbsp olive oil in a large skillet over medium heat.
5. Add 1 chopped onion, 2 minced garlic cloves, 2 diced carrots, and 2 chopped celery sticks; sauté until vegetables are softened, about 5–7 minutes.
6. Stir in 200 g brown lentils, 2 tbsp tomato paste, 1 tsp dried thyme, and 1 tsp dried rosemary, coating the lentils evenly.
7. Pour in 400 ml vegetable broth, bring to a simmer, and cook until lentils are tender and liquid is mostly absorbed, about 20 minutes.
8. Stir in 100 g frozen peas and adjust seasoning with additional salt and pepper if needed.
9. Transfer the lentil mixture into a baking dish and gently spread the mashed sweet potatoes on top in an even layer.
10. Bake in the preheated oven for 20–25 minutes, or until the top is lightly golden and edges are bubbling. Let cool slightly before serving.

Frequently Asked Questions
Here are some quick answers to the most common queries about this Shepherd’s Pie:
- How long does it take to prepare and cook this recipe from start to finish?
From start to finish, you should allow about 1 hour and 10 minutes. That includes roughly 10 minutes to peel and chop the sweet potatoes and vegetables, 15 minutes to boil the potatoes until tender, 5–7 minutes to sauté the aromatics and vegetables, 20 minutes to simmer the lentils until the liquid is absorbed, and finally 20–25 minutes baking time for the assembled pie.
- Can I use different types of lentils, and how will that affect cooking time?
Yes, you can substitute brown lentils with green or red lentils. Green lentils have a similar cooking time of about 20 minutes, while red lentils cook faster, needing only about 15 minutes. If you use red lentils, keep an eye on the liquid level and reduce the simmering time accordingly to prevent mushy texture.
- How can I make this recipe completely vegan?
To make a vegan version, swap the butter for a plant-based spread and use a non-dairy milk such as almond or soy milk when mashing the sweet potatoes. Ensure your chosen spread and milk are fortified and free of animal products to maintain the creamy mash consistency.
- What is the best way to store and reheat leftovers?
Store any leftovers in an airtight container in the refrigerator for up to three days. To reheat, you can place individual portions in the microwave for two to three minutes until heated through, or reheat in a preheated oven at 180°C (350°F) for 10–15 minutes. You can also freeze the baked pie for up to two months; thaw overnight in the refrigerator before reheating.
- How can I achieve an extra golden or crispy top on the sweet potato mash?
For an extra golden finish, brush the top of the mash with a little melted butter before baking. You can also sprinkle a light layer of grated cheese over the mash in the last five minutes of baking or place the dish under the broiler for two to three minutes, watching closely to prevent burning.
- Can I prepare components ahead of time, and what’s the best way to assemble before baking?
Yes, you can prepare both the lentil filling and the sweet potato mash up to one day in advance. Store them separately in airtight containers in the refrigerator. When you’re ready to bake, spread the lentil mixture in your baking dish, smooth the chilled mash on top, then bake as directed. This helps maintain the texture of both components.
