Steps
Make the base:
Heat olive oil in a large pan over medium heat. Add onion (and garlic, if using), carrot, and celery; cook until soft.
Add minced meat and brown lightly. Stir in lentils, tomato purée, and Worcestershire sauce if using, along with thyme and rosemary.
Add a splash of stock and simmer for 10–15 minutes until thick and rich. Season well.Prepare the mash:
Boil the carrots, parsnips, and potatoes together in one pot until tender (about 15 minutes).
Drain and mash with olive oil, a pinch of nutmeg, salt, and pepper until smooth.Assemble:
Spoon the meat–lentil mixture into an ovenproof dish. Spread the mash evenly on top.
Rough up the surface with a fork for texture.Bake and grill:
Place in a 200 °C/390 °F oven for 20 minutes.
Switch on the grill setting for the final 10 minutes to brown and crisp the top.Make the minty peas:
Boil or steam peas for 3 minutes, then toss with chopped mint and a drizzle of olive oil or butter.Serve:
Spoon generous portions of pie with a side of minty peas.
Variations
- Make it vegetarian by skipping the meat and doubling the lentils.
- Add chopped mushrooms or courgette to increase plant variety.
- Swap in a little sweet potato or swede in the mash for more colour and fibre.
Why It Works
Traditional comfort with a smart twist — lentils stretch the protein, add fibre, and help stabilise blood sugar.
Carrot, parsnip, and potato create a mash that’s naturally creamy and satisfying but lower in glycaemic load than pure potato.
The minty peas add freshness and another plant to your weekly count.
Notes
Plant-count tip: 11 plants including herbs and peas.
Time-saver tip: use frozen chopped onions and ready-cooked lentils to cut prep time by half.
Extra richness: sprinkle a little grated cheese on top before baking — something with strong flavour such as Red Leicester, Cheddar, or an equivalent adds depth without needing much.
Carrots in the base can also make for a nice crunch
