7 Budget-Friendly Vegetarian Autumn Dinners You'll Actually Want To Eat

Autumn is genuinely one of the best times of year to eat vegetarian on a budget. The seasonal produce is cheap, filling, and actually good: squash, sweet potatoes, lentils, leeks, cavolo nero, root vegetables.

A bag of own-brand red lentils from a supermarket costs well under £2 and feeds four people. A butternut squash is typically around £1 to £1.50. You don't need to spend a lot to eat well this time of year.

These seven recipes are the sort of thing you'd make when you don't want to think too hard but you do want something that fills you up.

1. Red lentil dhal with spinach

Dhal is one of those dinners that costs almost nothing and takes about 25 minutes. Red lentils, a tin of chopped tomatoes, an onion, garlic, and a few spices (cumin, turmeric, coriander) and you're most of the way there. Stir in a couple of handfuls of frozen spinach at the end.

It serves four easily, it keeps well in the fridge for three days, and it tastes even better the next day. Serve with rice or cheap flatbreads. Total cost per serving is usually around 50p to 70p depending on where you shop.

2. Leek and potato soup

This is a proper soup, not a starter. Thick, filling, and made from three main ingredients: leeks, potatoes, and stock. Fry the leeks in butter until they're tender, add the potatoes and stock, simmer for 20 minutes, and blitz.

Leeks and potatoes are some of the cheapest vegetables you can buy in autumn. A good loaf of bread alongside makes it a full meal. If you have cream in the fridge it's worth a splash at the end, but it doesn't need it.

3. Roasted squash and chickpea tray bake

Tray bakes are useful for a reason. You chop everything, toss it in oil and spices, put it in the oven for 35 to 40 minutes, and that's it. For this one: butternut squash cubed, a drained tin of chickpeas, red onion, and a good pinch of smoked paprika and cumin.

The chickpeas go crispy at the edges and the squash caramelises, and it's genuinely satisfying. Serve over a grain or with pitta. Bulgur wheat takes around 10 minutes and pearl barley around 25 to 30, so pick whichever suits your timing.

4. Black bean and sweet potato chilli

This one takes about 35 minutes and costs well under £1 a portion. Two tins of black beans, two sweet potatoes cubed and cooked down in the pan, a tin of chopped tomatoes, smoked paprika, cumin, a bit of chilli if you like it. Let it simmer until the sweet potato is cooked through and the sauce has reduced.

It freezes brilliantly, which matters when you're cooking on a budget. Make a big batch on Sunday and you've got two or three weeknight dinners sorted. Serve with rice or baked potatoes.

A note on spice levels: this is mild as written. If you want heat, a teaspoon of chipotle paste will do more than dried chilli flakes.

5. Cavolo nero and white bean pasta

Pasta is the obvious budget dinner, but this one is worth making deliberately rather than just as a fallback. Cook a big bunch of cavolo nero (or regular kale if that's what's available) in olive oil with garlic until it's wilted and starting to crisp at the edges.

Add a tin of white beans, cannellini or butter beans both work, and a ladle of pasta cooking water to bring it together.

Toss in your cooked pasta and a generous amount of parmesan if you eat it, or nutritional yeast if you don't. Cavolo nero is usually around £1.35 to £1.50 for a 200g bag and it's one of the most nutritious vegetables you can buy in autumn.

6. Mushroom and lentil cottage pie

Puy lentils and mushrooms together have enough texture and depth that you won't miss it.

Cook down a mix of mushrooms (closed cup are fine, chestnut are better) with onion, carrot, celery, and Puy lentils in vegetable stock and a good splash of Worcestershire sauce.

Check the label, most standard versions contain anchovies and aren't vegetarian; Henderson's Relish is a reliable alternative, approved by the Vegetarian Society as suitable for vegans. Top with mashed potato and bake for 20 minutes until the top is golden.

It takes a bit longer than the other dishes here, about an hour total, but most of that is hands-off time. Dried Puy lentils typically cost around £2 to £2.50 a bag and you'll use half for this recipe, which serves four.

7. Spiced parsnip and red lentil soup

Parsnips are cheap in autumn and they make a really good soup base. Roast them first with a little cumin and coriander (this takes 20 minutes and is worth doing) then simmer with red lentils, onion, garlic, vegetable stock, and a tin of coconut milk.

Blitz until smooth. It's thick, warming, and filling enough to be dinner with bread. The coconut milk rounds it out noticeably, and a 400ml tin costs around 75p to £1.20 depending on the brand.

Parsnips at this time of year are often 50p to 70p for a bag of four or five, so the whole pot costs roughly £3 to £3.50 and serves four comfortably.

All seven of these come in under £1.50 per serving, most of them under £1. They're also the sort of dinners that get better as the week goes on because you've got leftovers for lunch or a second dinner without having to cook again.

Autumn produce is at its best right now and it's genuinely some of the cheapest food you can buy. That's worth taking advantage of.
