This nutritious slow cooker lentil soup is packed with vegetables and creamy red lentils. I love to top it off with some crispy tortilla strips to add a bit of crunch too.

This is a comforting, hearty soup that satisfies my Winter soup cravings, whilst also feeling like it’s doing me lots of good.
The lentils soften up and give the soup a creamy flavour and a lovely thick, filling texture.
The cheese and crispy tortilla strips give it that extra bit of luxury, so it doesn’t feel un-enjoyably healthy! You know where I’m coming from here right? No-one likes diet-soup. If it doesn’t taste good, it’s not worth eating!
So, what do we need to make these bowls of goodness?

👩🍳PRO TIP If you want a smooth soup you can leave out the spinach and blend the soup up (it’ll go a murky colour if you blend it with the spinach).

The kids go wild for the crispy tortilla strips. It’s worth making extra to nibble on later.

Hi Nikki, do the dried lentils need to be boiled first before I proceed with the lentil soup?
I have actually added a carton of passata and a carton of cannelloni beans as mine just did not have a lot of taste to it. Will leave overnight and have tomorrow for lunch when I will reheat and add the grated cheese.
Thank you for the recipe.
Could I use green lentils instead of red!
I dont see why you cannot use green lentils, better than no lentils.
Could I freeze the slow cooked lentil soup?
