Step‑by‑Step Instructions for Sweet Potato & Lentil Shepherd’s Pie
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This ensures that your Sweet Potato & Lentil Shepherd’s Pie will bake evenly, creating that irresistible golden top. While the oven heats up, gather your ingredients and prep your workspace for an enjoyable cooking experience.
Step 2: Prepare Sweet Potatoes
Peel and chop 2-3 medium sweet potatoes into uniform chunks. Place them into a pot of boiling salted water, cooking for about 15 minutes or until they’re fork-tender. Once cooked, drain the water and mash the sweet potatoes with a pinch of salt and pepper until they’re creamy and smooth.
Step 3: Sauté Aromatic Vegetables
In a large pot, heat 2 tablespoons of olive oil over medium heat. Add finely chopped onions, carrots, and celery, sautéing for 5-7 minutes until they are softened and fragrant. Stir occasionally to ensure even cooking, which will boost the savory base flavor of your lentil filling.
Step 4: Add Garlic and Herbs
Incorporate 2 cloves of minced garlic, along with a teaspoon each of thyme and rosemary into the pot. Cook for an additional minute, stirring constantly to release the herbs’ aromatic oils. The enticing aroma will signal that your filling is on its way to being incredibly flavorful.
Step 5: Cook Lentils with Broth
Stir in 1 cup of rinsed lentils and 2 cups of vegetable broth into the vegetable mixture. Increase the heat to bring the mixture to a boil, then reduce it to a simmer. Let it cook for 20-25 minutes, stirring occasionally, until the lentils are tender, and the broth is absorbed, creating a hearty filling.
Step 6: Assemble the Pie
Spread the fragrant lentil mixture evenly into a baking dish, smoothing it out to ensure every bite is flavorful. Carefully top it with the creamy mashed sweet potatoes, spreading them evenly over the lentils. Use a spatula to create a smooth surface, or make divots for a rustic look.
Step 7: Bake to Perfection
Place the assembled Sweet Potato & Lentil Shepherd’s Pie in your preheated oven, baking for 25-30 minutes. Keep an eye on it until the top turns golden brown and the filling is bubbling up around the edges. The mouthwatering aroma will let you know it’s almost ready to serve!

Expert Tips for Sweet Potato & Lentil Shepherd’s Pie
- Perfectly Mashed: Use a potato masher to ensure your sweet potatoes are creamy, avoiding lumps that can disrupt the texture of your Shepherd’s Pie.
- Flavor Boost: For an extra kick, add a teaspoon of chili flakes to the lentil mixture; this balances beautifully with the sweet topping and enhances the dish.
- Even Chunks: Cut sweet potatoes into uniform pieces to ensure they cook evenly, preventing some from being undercooked while others become mushy.
- Storage Secrets: Store leftovers in an airtight container for up to three days to maintain freshness. Reheating in the oven restores texture better than the microwave.
