Step-by-Step Instructions
Preparation Phase
- Preheat the oven to 400°F (200°C).
- Peel and chop sweet potatoes, then boil them in salted water until tender. Drain and mash with a bit of olive oil, salt, and pepper.
Cooking Phase
- In a large skillet, heat olive oil over medium heat. Add onion, carrots, and celery. Cook until softened, about 5-7 minutes.
- Add garlic and mushrooms, and cook for an additional 3-4 minutes.
- Stir in lentils, vegetable broth, thyme, rosemary, salt, pepper, green peas, and tomato paste. Simmer for about 10 minutes.
Assembly and Baking Phase
- Spread the lentil mixture in a baking dish, then top with the mashed sweet potatoes, smoothing them out.
- Bake in the oven for 25-30 minutes, or until the top is slightly golden.
- Allow to cool slightly before serving.

Chef Tips for Perfect Results
- Use fresh herbs to enhance the flavor profile of the dish.
- Opt for organic sweet potatoes when possible for the best taste.
- Adjust the consistency of the lentil mixture by adding more or less vegetable broth depending on preference.
- For added creaminess, mix in a splash of plant-based milk into the mashed sweet potatoes.
- Let the pie cool for a few minutes to allow the flavors to settle before serving.
- Pair with a side salad for a fresh contrast to the dish.
Common Mistakes to Avoid
- Overcooking the Sweet Potatoes: This can make the mash watery. Ensure you check for tenderness and drain properly.
- Skipping the Seasoning: Not seasoning the filling can lead to a bland dish. Taste and adjust seasoning as needed.
- Not Mixing Thoroughly: Failing to mix the lentil filling well can result in uneven flavors. Stir thoroughly to combine all ingredients.
- Incorrect Baking Time: Removing the pie too early may leave the filling undercooked. Allow it to bake until golden on top.
- Using Low-Quality Ingredient: Using canned or low-quality lentils can affect the dish. Opt for good quality for the best taste.
