Cheap Lentil Recipes That Taste Like a Proper Dinner

When the grocery money runs thin by the third week of the month, dinner tends to slide toward plain pasta and toast. Lentils fix that problem better than almost anything else in the shop, and these cheap lentil recipes are the ones I actually cook when the budget is tight but I still want a meal that feels like dinner. A 1 kg bag of dried lentils costs around 2.50 to 3.50 at most supermarkets, cooks without soaking, and turns into roughly 12 generous portions.

Below are five recipes with real costs per serving, the type of lentil each one needs, and the small tricks that stop lentils tasting like health food.

Which lentils to buy for cheap lentil recipes

Not all lentils behave the same way, and using the wrong one is the main reason people decide they do not like them.

If you only buy one, buy red split lentils. They are the cheapest, the fastest and the most forgiving. Brown lentils are the second bag worth keeping. Puy lentils are lovely but often cost twice as much, so save them for when a recipe really depends on firmness.

Five cheap lentil dinners with real costs

Prices below are based on a mid-range supermarket shop this autumn, rounded up, and assume you already have oil, salt and a few basic spices.

1. Red lentil dal (about 0.55 per serving)

Fry one chopped onion in 2 tablespoons of oil for 8 minutes until golden. Add 2 crushed garlic cloves, a thumb of grated ginger, 1 teaspoon of cumin, 1 teaspoon of turmeric and half a teaspoon of chilli. Stir for 1 minute, then add 250 g red lentils and 900 ml water. Simmer for 20 minutes, stirring now and then, until thick. Finish with salt and a squeeze of lemon. Serves four with rice.

2. Lentil bolognese (about 0.80 per serving)

Soften a diced onion, carrot and celery stick for 10 minutes. Add 2 garlic cloves, a tablespoon of tomato paste and cook for 2 minutes. Add 200 g brown lentils, a 400 g tin of chopped tomatoes, 600 ml stock and a teaspoon of dried oregano. Simmer for 30 minutes. Serve over 400 g spaghetti for four people. Half lentils and half beef mince also works if you want to stretch a small pack of meat.

3. Lentil and potato curry (about 0.70 per serving)

Make the dal base, but add two potatoes cut into 2 cm cubes along with the lentils and an extra 200 ml water. The potatoes make it heartier, and it needs no rice. A handful of frozen spinach stirred in at the end adds colour for pennies.

4. Lentil shepherd's pie (about 0.90 per serving)

Use the bolognese mixture, cooked until thick, as the filling. Top with 800 g mashed potatoes and bake at 200 C for 25 minutes until the top browns. It feeds four to six and reheats perfectly for lunch.

5. Spiced lentil soup (about 0.45 per serving)

Fry an onion and two carrots, add a teaspoon each of cumin and smoked paprika, 200 g red lentils and 1.2 litres of stock. Simmer 20 minutes, blend half, and stir back together. This is the cheapest meal on the list and a good way to use up tired vegetables.

How to make lentils taste good every time

Lentils are mild, so seasoning carries the whole dish. Four habits make the difference between flat and satisfying.

• Brown the onion properly. Eight to ten minutes over medium heat, not three. That caramelised sweetness is the backbone of the flavour.
• Bloom the spices in oil. Thirty to sixty seconds in hot fat before the liquid goes in wakes up dried spices.
• Salt at the end. Salting red lentils early is fine, but brown and green lentils can stay firm if salted heavily at the start. Add most of it in the last 10 minutes.
• Finish with acid. A squeeze of lemon, a splash of vinegar or a spoon of yoghurt lifts the whole pot. This step is the one people skip, and it is the one that matters most.

The soaking advice you can ignore

Plenty of older cookbooks tell you to soak lentils overnight and to rinse them in several changes of water. For red, brown and green lentils, soaking is a waste of time. Unlike chickpeas or kidney beans, lentils are small and thin-skinned enough to cook through in under 35 minutes from dry. Soaking them can actually make red lentils turn to mush before the flavours have developed.

A single quick rinse in a sieve is worth doing to remove dust and the occasional small stone. Beyond that, skip the planning. The fact that lentils go from cupboard to table in half an hour is exactly why they suit a budget kitchen, because the cheapest dinner is useless if it needs a decision made the night before.

Buying, storing and batch cooking

Dried lentils keep for a year or more in an airtight jar, though very old ones take longer to soften. Buying the 2 kg bags from the world foods aisle usually cuts the price per kilo by a third compared with small 500 g packets. Keep them somewhere you can see them, which our guide to organizing a small pantry so food gets used explains in detail.

Cooked lentil dishes keep for four days in the fridge and three months in the freezer. Dal and bolognese both freeze in flat bags, which thaw in about an hour in a sink of cold water. If you cook for a household, the planning ideas in feeding a family on a tight weekly grocery budget pair well with a big Sunday pot of lentils, and the soup or curry from this list slots straight into meal prep lunches that still taste good on Thursday.

Frequently asked questions

Are lentils cheaper than meat for protein?

By a wide margin. Dried lentils provide around 24 g of protein per 100 g dry weight for roughly 0.30, while the same protein from beef mince costs several times more. They also add fibre that meat does not.

Do you need to soak lentils before cooking?

No. Red, brown, green and Puy lentils cook from dry in 15 to 35 minutes. A quick rinse to remove dust is enough. Soaking is only needed for larger pulses like chickpeas and kidney beans.

How many servings are in a kilo of dried lentils?

About 12 to 14 main meal portions. Dried lentils roughly double or triple in volume when cooked, and 70 to 80 g dry per person is a filling serving alongside rice, bread or potatoes.
