Why Use Red Lentils In A Soup Recipe?

Lentils never used to really feature in my day-to-day eating habits, but since including them in a few soup maker recipes, I can’t get enough of them.

They pack a real punch for protein, and they are surprisingly filling.

Whether it’s just to add a handful into a soup to thicken it up or to make them a more substantial part of a recipe, they are the perfect store cupboard standby.

They are really cheap to buy and take minimum preparation – all you need to do is rinse them in water before adding them; no overnight soaking is required 🙂

How To Make Tomato and Lentil Soup In A Soup Maker

As you know, I like my recipes to be as simple as possible. I prefer short ingredient lists and minimal instructions!

This recipe certainly fits this criteria, although you can add extra spices and herbs if you like.

tomato lentil soup ingredients

The ingredients are 1 onion, 2 cloves of garlic, 1 medium carrot, 100g red lentils, 6 fresh tomatoes and vegetable stock up to the line.

I make all my soups these days in a soup maker, but they can also be made in a pot on the stove. Just follow the same steps in the recipe below, but at the end, you’ll need to use a hand blender to whizz it smooth.

Side Note: If you don’t already have a soup maker and are tempted, check out my soup maker reviews.

Making It

I sometimes sauté at least the onions and garlic at the beginning, but on this occasion, I just skipped that step and added all the ingredients at the same time.

If you want to sauté first, use an oil of your choice (I usually use olive oil or rapeseed oil) or a little butter.

There is no need to peel the skin of the tomatoes, wash and quarter them before adding them to the soup maker.

You also don’t need to soak the red lentils. Wash them under a cold water tap before adding them to the soup maker jug.

I typically add a stock pot or cube direct to the jug and then top the soup maker up to the maximum line with hot water.

Make sure you give everything a really good stir before setting the soup maker off; this will ensure that no ingredients are stuck to the bottom or the side.

Side Note: Some people have reported problems with burning on the bottom of the soup maker. Some tips to avoid this include adding a little oil to the base of the soup maker, adding the lentils last and making sure there is enough stock in the jug.

I set this soup off on smooth, and then 20 to 30 minutes later – depending on what soup maker you have – I had a deliciously smooth tomato and lentil soup.

You can, of course, also set it off on chunky if that’s more your thing 🙂

Adding Extras To This Soup

If you feel like adding anything extra you can try adding some dried herbs or spices.

If you would like to turn it into a creamy tomato and lentil soup just stir in some yoghurt or cream at the end.

If you prefer a more intense tomato taste you could also add in a little tomato puree.

To make this recipe spicy, add 1 tbsp of curry paste or 1 tsp of curry powder.

Tomato and Lentil Soup (in a Soup Maker)

Yield: 4 people
Prep Time: 5 minutes
Cook Time: 30 minutes
Total Time: 35 minutes

A filling, delicious and economical soup! I love adding lentils to soup, this tomato and red lentil soup really ticks all the boxes on taste, simplicity and taste!


  • 1 onion, chopped
  • 2 cloves garlic, sliced
  • 1 carrot, sliced (approx 75g)
  • 100g red lentils, rinsed
  • 4 to 6 fresh tomatoes, I used on the vine, chopped
  • 1 vegetable stock pot/cube
  • Seasoning according to taste


  1. Optionally saute the onions and garlic in a little oil.
  2. Add all the ingredients to the soup maker and make sure you give it a good stir round and ensure no ingredients are stuck to the bottom.
  3. Set off on smooth.
  4. Season according to taste.


There is no need to soak the red lentils; wash them under a cold water tap.

The tomatoes you use will affect your soup taste; I prefer to use on the vine tomatoes; I tend to use between 4 and 6 tomatoes, depending on their size.

If you don't have fresh tomatoes, you can substitute them with a can of chopped tomatoes.

I use a vegetable stock pot because I find they have more flavour than the cubes. If you are using a cube, you might want to add some dried herbs or spices to boost the taste.

Brilliant recipe. I used Tinned Tomatoes (didn't have fresh in the Fridge and a half teaspoon of Harissa paste. A good splash of Worcester sauce once served. A firm favourite in my house.

Sorry but the soup wasn't nice, I ended up throwing it out. Followed the recipe exactly apart from the stock as my ninja soup maker only needed 400ml to reach max line. The soup just tasted like onions and couldn't taste tomatoes at all, just pure onion

Great recipe I did as suggested and added a tbsp of tomato puree I also added some celery with other vegetables ,oregano and basil the end result was a flavoursome delicious soup great if you are watching the calories. I did soften the onion first in some fry light which worked well. Overall a tasty soup and great for using up all of the tomatoes I have grown on my allotment this summer.
