Vegetarian Lentil Shepherd’s Pie

Often called 'Shepherdless Pie,' this vegetarian wonder proves you don't need meat for a hearty meal. Lentils are an excellent plant-based substitute: they retain a nice bite after cooking, and their earthy richness pairs perfectly with root vegetables. It's the ultimate comfort food for cold nights.

Instructions

1

Rinse the lentils and parboil them in salted water until semi-soft (about 15-20 minutes). Meanwhile, peel and boil the potatoes until tender.

Tip: Don't cook the lentils all the way to mush; they will continue to soften in the sauce.
2

Sauté the chopped onion, garlic, and carrots in half of the butter. Stir in the tomato paste and cook for 1 minute to caramelize.

Tip: Frying the tomato paste removes its raw acidity and deepens the color of the stew.
3

Add the parboiled lentils, thyme, vegetable broth, and peas. Simmer until the mixture thickens into a rich stew (approx. 10 minutes).

Tip: The natural starch from the lentils will thicken the liquid, creating a creamy sauce.
4

Mash the cooked potatoes with the remaining butter, milk, and egg yolk. Season with salt and pepper.

Tip: The starch and butter fat create a sturdy structure that sits perfectly on top of the lentil mix.
5

Spread the lentil mixture into the baking dish and cover with the mashed potatoes. Use a fork to create a textured pattern on top.

Tip: A rough surface creates delicious crispy peaks.
6

Bake at 400°F (200°C) for 20-25 minutes until golden brown.

Tip: Let it cool slightly before serving so the filling sets.

Recipe FAQ

Do I need to soak the lentils?
Brown or green lentils benefit from a short soak to speed up cooking, but they will tenderize in about 30-40 minutes without it. Avoid red lentils as they turn to mush.
How can I deepen the flavor?
Tomato paste and thyme are key, but a splash of red wine in the stew works wonders (the alcohol cooks off, leaving a rich aroma).
