This hearty lentil stew recipe is flavoured with mustard which adds tonnes of flavour! It is a vegetarian lentil stew that is perfect served with slices of crusty bread and a green salad. But it also is a great side dish for pork and chicken. Yoghurt is stirred into this mustard lentil stew for creaminess, but it could be omitted or substituted with plain soy yoghurt to make this lentil stew vegan!

Let’s get this out of the way first. This Mustard Lentil Stew isn’t pretty. No amount of chopped parsley is going to liven up a dish of brown and beige veggies. But. BUT. What this dish lacks in looks it makes up for in flavour. BIG TIME. And not only that, but it is so quick and simple to make, its appearance will be the last thing on your mind.
Carrot, celery and onion are cooked with some lentils and stock. Then add mustard and a little bit of yoghurt and you are done. Less than 10 ingredients whacked together in under half an hour to make a dish so tasty you’ll be singing.
(If you don’t like mustard I’m really sorry, forget everything you’ve just read and maybe try these Vietnamese Pesto Noodles instead).

In an effort to eat more plant-based lentils have become a go-to in our household. They’re packed with protein and fibre are easy to throw into all sorts of dishes, from salads to curries to soups. This dish goes really well with things like chicken or pork, something that can stand up to the bold mustardy flavours. However, all that protein and fibre means it works just as well on its own as a balanced dish that will keep you full. Serve it with some crusty bread for dunking purposes and a green salad for a little extra crunch and you’re sorted.
I tend to use Merchant Gourmet Puy Lentils for this, and many other, recipes. They’re cooked with some added onion and bay leaf, which adds an extra layer of flavour. Plus it’s as simple as throwing the whole sachet in the pan. Bob’s your Uncle. Tinned lentils would work just as well, plus they’re cheaper. Do you, boo 😘
Can I use something else instead of lentils?
For sure! Any type of cooked bean or pulse should work. Butterbeans would be a good fit.
