Ingredients You’ll Need
Here’s a closer look at what goes into this cozy dish and why each item matters:
Sweet Potatoes (2 large)
They serve as the topping. Once boiled and mashed, sweet potatoes become silky and naturally sweet. Their texture creates the perfect contrast to the savory lentil layer.
Lentils (1 cup, rinsed)
These are the backbone of the filling. Brown or green lentils work best as they hold their shape and have a meaty texture once cooked.
Onion (1, chopped)
Adds a savory base to the dish. When sautéed, onion brings out a sweet, mellow flavor that complements the other ingredients.
Carrots (2, diced)
Carrots bring subtle sweetness and color. They hold their texture when cooked and give the filling a nice contrast.
Celery (2 stalks, diced)
Celery offers a gentle bitterness and aromatic quality, helping round out the flavor of the filling.
Garlic (3 cloves, minced)
Garlic intensifies the overall savoriness, making the dish taste heartier and more balanced.
Vegetable Broth (4 cups)
Used to cook the lentils, broth enhances the dish with savory depth. Choose low-sodium if you’re watching salt levels.
Dried Thyme (1 teaspoon)
Brings a warm, earthy element that complements both lentils and root vegetables.
Dried Rosemary (1 teaspoon)
A bold herb that adds a woodsy flavor, perfect for winter-style dishes like this.
Salt and Pepper (to taste)
Season to your preference. Start with a pinch and adjust as the dish comes together.
Olive Oil (2 tablespoons)
Used for sautéing vegetables and optionally mixed into the mash for smoothness.
Optional ingredients: Add chili flakes for some heat, vegan cheese on top for extra richness, or plant-based milk to the mash for added creaminess.
How to Make Sweet Potato & Lentil Shepherd’s Pie
This recipe is made in three easy phases. First, cook the sweet potatoes and prepare the mash. Then, sauté the vegetables and simmer the lentils with herbs and broth until thick and flavorful. Finally, assemble everything in a baking dish and bake until the top is golden and slightly crisp.
The result is a filling, satisfying meal that you can enjoy fresh or store for later.
Step-by-Step Instructions
Step 1: Boil the Sweet Potatoes
Peel and cut the sweet potatoes into chunks. Place them in a pot of salted water and boil until soft, which usually takes about 15 to 20 minutes. Drain and set aside.
Step 2: Cook the Vegetables
Heat the olive oil in a large saucepan over medium heat. Add chopped onion, carrots, and celery. Cook for 7 to 8 minutes, stirring regularly, until the vegetables soften and release their aroma.
Step 3: Add Flavor
Stir in the minced garlic, thyme, and rosemary. Cook for another minute until the herbs are fragrant.
Step 4: Simmer the Lentils
Pour in the rinsed lentils and vegetable broth. Stir to combine, bring to a boil, then reduce the heat. Simmer for 25 to 30 minutes, or until the lentils are soft and most of the broth has cooked off.
Step 5: Mash the Sweet Potatoes
While the lentils are cooking, mash the boiled sweet potatoes with salt and pepper. For a creamier texture, mix in a bit of olive oil or plant milk.
Step 6: Assemble
Preheat your oven to 400°F (200°C). Spread the cooked lentil mixture into a baking dish. Top with the mashed sweet potatoes, smoothing the surface with a spoon or spatula.
Step 7: Bake and Serve
Place the baking dish in the oven and bake for 25 to 30 minutes, or until the top starts to turn golden. Let the pie rest for a few minutes before serving.
Helpful Tips
Let the lentil mixture simmer uncovered until most of the liquid has evaporated. This helps prevent the final dish from becoming runny.
Taste and adjust your seasonings before baking. You can always add more salt or herbs as needed.
For a golden, slightly crisp topping, drag a fork across the mashed potatoes to create ridges that brown in the oven.
This dish is also great for meal prep. Make it ahead and refrigerate before baking, or freeze individual portions to reheat during the week.
