Ingredients
- 1 ½ cups dried green or brown lentils

- 1 tablespoon olive oil
- 1 small onion, diced
- 2 cloves garlic, minced
- 2 carrots, diced
- 1 cup frozen peas
- 1 tablespoon tomato paste
- 1 teaspoon dried thyme
- 1 teaspoon paprika
- ½ teaspoon salt
- ½ teaspoon black pepper
- 1 tablespoon soy sauce

Sweet Potato Topping
- 3 large sweet potatoes, peeled and cubed
- 2 tablespoons butter or vegan butter

Preparation Steps
Step 1: Cook Lentils
In a saucepan, combine lentils and vegetable broth. Bring to a boil, then simmer 20–25 minutes until tender. Drain excess liquid if needed.
Step 2: Cook Vegetables
In a skillet, heat olive oil over medium heat. Sauté onion, garlic, and carrots until softened and fragrant.
Step 3: Make Filling
Stir in tomato paste, thyme, paprika, salt, pepper, soy sauce, and Worcestershire. Add cooked lentils and peas. Simmer 5–10 minutes until thickened.
Step 4: Cook Sweet Potatoes
Boil sweet potato cubes in salted water until fork-tender, about 15 minutes. Drain well.
Step 5: Mash Topping
Mash sweet potatoes with butter, milk, salt, and pepper until smooth and creamy.
Step 6: Assemble
Spread lentil filling in a baking dish. Spoon mashed sweet potatoes evenly over the top.
Step 7: Bake
Bake at 375°F (190°C) for 20–25 minutes until heated through and lightly golden on top.
Variations
- Add mushrooms for deeper umami flavor and a meatier texture
- Mix lentils with cooked quinoa for extra protein and texture
- Add corn or green beans for more vegetable variety
- Top with shredded cheese before baking for a creamy crust
- Use mashed potatoes instead of sweet potatoes for a classic taste
- Add smoked paprika for a subtle smoky note

Cooking Notes
- Lentils should be tender but not mushy so the filling keeps structure
- If filling seems too loose, simmer longer to reduce moisture before baking
- Sweet potatoes should be well drained to prevent watery mash
- Mash topping until smooth for best spreading and presentation
- A fork can be dragged across the topping to create texture that browns nicely
- Baking allows flavors to meld and the top to lightly caramelize
- Dish can be assembled ahead and refrigerated before baking
- Rest 10 minutes after baking so layers set for cleaner serving
Serving Suggestions
- Serve hot with a simple green salad for balance and freshness
- Pair with crusty bread to scoop up the hearty filling
- Add a spoon of yogurt or sour cream for creamy contrast
- Sprinkle fresh herbs like parsley or chives for brightness
- Serve alongside roasted vegetables for a full vegetarian meal
- Add a drizzle of olive oil or chili oil for richness and warmth
- Pair with pickled vegetables to cut through the sweetness
- Serve in shallow bowls for cozy comfort-food presentation
Tips
- Cook lentils just until tender to avoid mushy texture
- Season filling generously since lentils absorb flavor
- Taste mash and adjust salt before topping
- Spread topping gently so layers stay distinct
- For golden peaks, broil briefly at the end
- Use a wide baking dish for better topping coverage
- Let cool slightly before slicing for neat portions
- Leftovers reheat well and flavors deepen next day
