Ingredients
Essential Ingredients for Flavor
This dish calls for a mix of fresh vegetables, hearty lentils, and sweet potatoes. Here’s what you’ll need:
- 2 lbs sweet potatoes, peeled and cubed
- 1 cup green or brown lentils, rinsed
- 1 large onion, diced
- 2 carrots, chopped
- 2 cloves garlic, minced
- 2 tbsp olive oil
- 1 tsp smoked paprika
- 1/2 tsp ground cumin
- 2 cups vegetable broth
- 1 cup frozen peas
- Salt and pepper to taste
Substitutions and Variations
If you want to get creative, there are plenty of substitutions and variations you can try. Swap out the lentils for chickpeas or black beans for a different flavor profile. For added richness, you can stir in a few tablespoons of cream or coconut milk into the mashed sweet potatoes. Feel free to add other vegetables such as bell peppers or zucchini for extra nutrition and flavor.

Step-by-Step Instructions
Preparing the Lentil Filling
Begin by heating the olive oil in a large skillet over medium heat. Add the diced onion and carrots, sautéing until they become tender and fragrant. Stir in the garlic, smoked paprika, and cumin, cooking for an additional minute. Add the lentils and vegetable broth, bringing the mixture to a simmer. Cover and cook until the lentils are tender, about 25-30 minutes. Once the lentils are cooked, stir in the frozen peas and season with salt and pepper to taste.
Roasting the Sweet Potatoes
While the lentils are cooking, preheat your oven to 400°F. Spread the cubed sweet potatoes on a baking sheet, drizzle with olive oil, and sprinkle with salt. Toss to coat evenly. Roast in the oven for 20-25 minutes or until the sweet potatoes are tender and slightly caramelized around the edges. Once done, remove from the oven and mash until smooth. You can add a splash of vegetable broth or milk to reach your desired consistency.
Assembling and Baking the Pie
Lower the oven temperature to 375°F. In a greased baking dish, spread the lentil filling evenly across the bottom. Top with the mashed sweet potatoes, spreading it out to cover the lentils completely. Use a fork to create peaks on the mashed potatoes, which will crisp up during baking. Bake for 20-25 minutes, or until the top is slightly golden and the filling is bubbling around the edges.
Pro Tips
To make the most of this dish, consider these helpful tips:
- For a creamier texture, add a dollop of sour cream or Greek yogurt to the mashed sweet potatoes.
- Use fresh herbs like thyme or rosemary to enhance the flavor of the lentil filling.
- If you’re short on time, use canned lentils instead of dried, reducing the cooking time significantly.
- For a crunchy topping, sprinkle breadcrumbs or crushed nuts over the sweet potatoes before baking.
One of the most important tips is to let the pie cool for a few minutes before serving. This allows the flavors to meld together and makes the pie easier to slice and serve. Enjoying this dish with family and friends is truly the best part of the experience.
