Anyway, back to this beautiful slow cooker vegetarian chili recipe. Not only is it healthy, incredibly delicious and filling – it freezes very well too. This makes it a perfect make ahead lunch for those cold winter days! I’ve taken both this and an epic lentil dahl to work in my thermos flask on many occasions and every single time my colleagues get jealous of how amazing it smells! (While I enjoy how amazing it tastes!)

Vegetarian Chili Recipe Tips

  • Make sure to chop the carrots quite small as they take much longer to cook compared to the other ingredients. The larger they are, the longer they’ll take – the smaller they are, the less time they’ll take.
  • If you’re stocking up your freezer – bag/box them in individual sized portions. That way you’ll create less possible waste.
  • Don’t substitute the red lentils for another colour. Split red lentils are one of the most absorbent and, if you swap them for another, you’ll likely get quite a watery chili.
  • Not a fan of kidney beans? You can try swapping them for red beans, pinto beans or cannellini beans.
  • Want a seriously hearty dinner? Top a baked potato with a load of this chili, scatter with cheese and enjoy!

Then pour in the tinned tomatoes (2 x 400g | 14 oz tins), kidney beans (1 x 400g | 14 oz tin) and 300ml [1 + 1/4 Cup] of the vegetable stock. (Save the remaining 250ml [1 Cup] for later.) Give it all a really good stir then switch your slow cooker on low and cook for 5-6 hours.

When the cooking time is up, it will appear a little dry. That’s because the lentils have done their job and thickened it all up nicely. (No one likes a watery chili!) All that remains to do is to give it a good stir through, then gradually add that remaining 250ml (1 Cup) of vegetable stock.
