A hearty plant-based twist on the classic British comfort dish: green lentils simmered with carrots, celery, and tomato paste until rich and stew-like, then topped with fluffy mashed potatoes and baked until golden. Filling enough that no one will miss the meat.

Ingredients

pantry
  • 200 ggreen lentils
  • 600 mlvegetable broth
  • 2 tbsptomato paste
  • 1 tspdried thyme
  • 2 tbspolive oil
  • 1 tspsalt
  • 0.5 tspblack pepper
produce
  • 700 gpotatoes
  • 2carrots
  • 1onion
  • 2 stalkscelery
  • 2 clovesgarlic

Steps

  1. Peel and chop the potatoes into large chunks; place in a pot of salted water, bring to a boil, and cook 15–18 minutes until fork-tender.
  2. Meanwhile, dice the onion, carrots, and celery; mince the garlic.
  3. Rinse the lentils under cold water and check for debris.
  4. Heat the olive oil in a large skillet over medium heat.
  5. Add the onion, carrots, and celery; cook 6–7 minutes, stirring occasionally, until softened.
  6. Add the garlic and cook 1 minute until fragrant.
  7. Stir in the lentils, vegetable broth, tomato paste, and dried thyme; bring to a boil.
  8. Reduce heat and simmer, partially covered, 20–25 minutes, stirring occasionally, until the lentils are tender and the mixture has thickened; season with salt and pepper.
  9. Meanwhile, drain the potatoes and mash with a splash of the reserved cooking water or a little olive oil until smooth; season with salt and pepper.
  10. Preheat the oven to 400°F (200°C).
  11. Spread the lentil mixture in an even layer in a baking dish.
  12. Top with the mashed potatoes, spreading to the edges and creating texture with the back of a fork.
  13. Bake 15–20 minutes, until the potato topping is set and lightly golden at the edges.
  14. Let rest 5 minutes before serving.

Tips

  • Simmer the lentils uncovered near the end if the filling looks too thin — it should be thick enough to hold a spoon upright.
  • Rough up the surface of the mashed potato topping with a fork before baking to help it brown in spots.
  • Green lentils hold their shape better than red lentils here, giving the filling a heartier texture.
  • This reheats beautifully, making it a great make-ahead dinner.
