• 1/2 cup milk
• 1 teaspoon salt
• 1/4 teaspoon black pepper

For the Lentil Filling

• 1 tablespoon olive oil
• 1 medium onion, diced
• 2 carrots, diced
• 2 celery stalks, diced
• 2 cloves garlic, minced

How to Make Sweet Potato & Lentil Shepherd’s Pie

1. Prepare the Oven

Preheat the oven to 400°F.

2. Make the Sweet Potato Mash

Place the cubed sweet potatoes in a pot of water and boil for 15–20 minutes, until tender.

Drain well, then mash the sweet potatoes with the butter, milk, 1/2 teaspoon of salt, and black pepper until smooth and creamy.

3. Cook the Vegetables

Heat the olive oil in a large skillet over medium heat. Add the diced onion, carrots, and celery and cook for about 5 minutes, until the vegetables begin to soften.

4. Make the Lentil Filling

Add the minced garlic, cooked lentils, vegetable broth, tomato paste, dried thyme, smoked paprika, and remaining salt.

Stir well and simmer for approximately 8 minutes, allowing the flavours to come together and the filling to become savoury and rich.

5. Add the Peas

Stir in the frozen peas until evenly distributed throughout the lentil mixture.

Transfer the filling to a baking dish and spread it into an even layer.

6. Add the Sweet Potato Topping

Spoon the mashed sweet potatoes over the lentil filling. Spread them evenly across the surface, covering the filling completely.

7. Bake

Bake for 25 minutes, until the filling is bubbling and the sweet potato topping is lightly golden.

8. Serve

Allow the shepherd’s pie to cool slightly before serving. Spoon generous portions of the creamy sweet potato topping and hearty lentil filling onto plates.

Tips for Making the Best Shepherd’s Pie

• Cook the sweet potatoes until tender: They should mash easily for a smooth topping.
• Drain the potatoes well: Removing excess water helps keep the mash creamy rather than watery.
• Simmer the filling: Give the lentils and vegetables enough time to absorb the broth and seasoning.
• Spread the topping evenly: This helps the sweet potatoes brown consistently during baking.
• Let it rest briefly: Allowing the pie to cool slightly makes it easier to serve.
