Kitchen Tools Needed

Large pot
Potato masher
Skillet
Baking dish (9×9 inches or similar)
Mixing spoon

Step-by-Step Instructions

Preheat your oven to 400°F (200°C).
In a large pot, combine the lentils and 4 cups (1 L) of water. Bring to a boil, then reduce heat and simmer for 20-25 minutes, or until tender. Drain and set aside.
While the lentils cook, place sweet potatoes in a separate pot, cover with water, and bring to a boil. Cook for 15-20 minutes until tender, then drain.
In a skillet, heat olive oil over medium heat. Add the onion, garlic, carrots, and celery. Sauté for about 5-7 minutes until the vegetables are soft.
Add the thyme, oregano, smoked paprika, and cooked lentils to the skillet. Pour in the vegetable broth, bring to a simmer, and add frozen peas. Season with salt and pepper. Let it cook for another 5-10 minutes, allowing the flavors to meld.
While the filling is cooking, mash the sweet potatoes. If using, mix in the milk and butter for a creamier texture. Season with a bit of salt.
Spread the lentil filling evenly in the bottom of a baking dish. Top with mashed sweet potatoes, smoothing them out with a spatula.
Bake in the preheated oven for 25-30 minutes, until the top is slightly golden and the edges are bubbling.

Pro Tips

For an even creamier topping, you can add more milk or use sour cream in the sweet potatoes.
Adding a sprinkle of cheese on top of the sweet potatoes before baking adds a deliciously crispy finish.
If you’re short on time, you can use pre-cooked or canned lentils to speed up the process.

Common Mistakes

Not cooking the lentils long enough can lead to a gritty texture. Make sure they are fully tender.
Overcooking the sweet potatoes can make them watery; check for tenderness but test often to avoid this.
Skipping the seasoning on both the filling and the potatoes can result in a bland dish, so taste as you go!

Variations

Swap sweet potatoes for regular potatoes if you prefer a classic topping.
Add spin or kale to the filling for extra greens.
Use ground meat substitutes to make it even heartier if desired.
Top the dish with crispy fried onions or breadcrumbs before baking for added texture.

Serving Suggestions

Serve it warm from the oven, perhaps with a simple side salad or some crusty bread. It’s a complete meal on its own but can be paired with steamed greens for added freshness.

Storage Instructions

Leftovers can be covered and stored in the refrigerator for up to 4 days. Alternatively, you can freeze individual portions for up to 3 months.

Reheating Tips

Reheat individual portions in the microwave or warm the entire dish in the oven at 350°F (180°C) until heated through, about 20-25 minutes, covered with foil to retain moisture.
