Vegetarian cottage pie, aka vegetarian shepherds pie or lentil cottage pie, is my meat free version of a traditional cottage pie. It has a vegetable and lentil pie filling topped with sliced potatoes and is perfect for family meals. This easy vegetarian recipe is made using cheap ingredients and is full of flavour making it a winner on both fronts.
Chop the onion and peel and dice the sweet potato.
Heat the oil in a roasting tin and roast the onion and sweet potato until soft.
Add the tomatoes, lentils, oregano, paprika, enough vegetable stock to cover, salt and pepper and stir. Simmer for about 30 minutes or until the lentils are cooked. Check regularly and add more vegetable stock or water if needed.
To prepare the cottage pie topping
Peel and slice the potatoes while the lentil mixture is cooking.
Bring the sliced potatoes to the boil, simmer for a few minutes to partially cook, and then drain.
To assemble
Transfer the cooked lentil mixture to an ovenproof bowl (approx 18cm diameter or equivalent size).
Arrange the partially cooked sliced potatoes over the lentil mixture making sure that all parts are covered.
Sprinkle the grated Cheddar cheese evenly over the top.
To cook
Cook in the top of the oven at gas mark 6, 200°C, 400°F for around 30 to 40 minutes or until heated through and until the top has browned.
Notes
Variations
A wide range of vegetables can be used to make this dish including carrots, peas, swede, runner beans, etc.
Add other pulses such as edamame beans or broad beans for extra protein.
Top your cottage pie with creamy mashed potatoes instead of sliced potatoes.
Add a topping of mashed sweet potatoes for a burst of colour.
Tips
The lentil pie filling can be cooked and stored in the fridge for a couple of days, or can be frozen.
Any leftovers can be covered with foil, stored in the fridge and reheated the next day.
I sometimes use half the filling to make a two serving cottage pie and freeze the other half to to save time another day. The photos here show a two portion version.
For a vegan version use a vegan cheese or omit the cheese and brush olive oil over the sliced potatoes before cooking.
The lentil mixture also makes a tasty topping for jacket potatoes. It is a good idea to freeze some in small quantities ready to use for a jacket potato filling.
