A souper simple soup recipe.

We have always loved tomato soup and our tomato and lentil soup is an easy to make family favourite recipe. Nutritionally this soup contains more fibre and iron than a standard tomato soup and we have upped the vegetable count compared to a certain popular tomato soup (that had probably better remain nameless!).

Why is tomato and lentil soup so good?

Our tomato and lentil soup recipe has no added sugar as it is sweet enough.

Don’t worry about the children/husbands/partners turning their noses up at the lentils either – just tell them it is tomato soup – once the soup is blended no one will know that lentils are hidden in there.

The lentils also add a creaminess to the texture of the soup.


Can you add other vegetables to this soup?

Yes, we often vary the base vegetables depending on what is in the fridge. You’ll often find a hidden courgette or a few peppers in the mix.

We’ve also included a handy twist on the tomato and lentil soup recipe too, where you can add 300g of sweet potatoes. This is a delicious twist on the basic tomato and lentil version.

It is a soup – do I need to cook down the base vegetables?

As with all our soups, we start by slowing cooking down the onions, leeks/celery, carrot and garlic until the onions turn translucent and the other vegetables start to soften. This ensures a gorgeous release of flavours, adds sweetness and enhances the overall delicious taste of the soup.


Can I batch cook tomato and lentil soup?

Absolutely, cooking a double batch of the tomato and lentil soup ensures we can feed the whole family and have an easy lunch ready and waiting in the fridge for a few days. We also then freeze the soup in double of single portion sizes for an easy go-to lunch.

How to store the tomato and lentil soup

Store the tomato and lentil soup in an airtight container in the fridge for up to 2 days or freeze, ideally in portion sizes.
