Smooth Lentil Soup with Carrot

Smooth lentil soup – or as we call it – normal soup is a staple in our house. Why ‘normal soup’? It’s the only soup my 5 year old eats every time. Please don’t tell him it’s got lentils in, or it will all be ruined! The smooth bit is important though, if the texture isn’t perfect, he just won’t go for it.

We don’t mind though, as this soup is tasty enough for the whole family to enjoy. We serve it with chilli flakes, cheese and sweetcorn, and sometimes more toppings. That way everyone can top it according to their own tastes.

Why eat lentil soup?

Lentils are an amazing food. Legumes are the food of the future – they’re high in protein, with a much lower carbon footprint than meat. They also contain fibre, carbohydrate and many of them are a good vegetarian source of Iron. Split red lentils are even better though, because they can be cooked so quickly – around 15 minutes is usually enough to get them tender. And they’re really cheap. What more do you need? With this smooth lentil soup even avowed lentil-haters will be slurping them down.

Tips for making Smooth Lentil Soup

I’ve given lentils precedence in the title because you can swap the root veg out for whatever your family’s favourite is. Slip a parsnip in, or try it with squash or celeriac. I’ve made variants with sweet potato.

You can also change the spice. If you all like it hot swap the cumin for 2tsp curry powder, or your favourite seasoning. We find that a hint of cumin is a flavour the whole family can enjoy, and prefer to add heat at the table.

I’m using stock powder that is made up with water. If you prefer to use ready made stock, broth or bouillon the soup may take a little longer to heat up. Please note, if you wish this soup to be vegan, check that the stock you are using is vegan.

Step By Step

First boil the kettle, then weigh out your carrots. Top and tail them, peel them and slice them. They don’t need to be dainty as they’ll be going in the blender at the end. Place them in a large pan.
