Rich, thick, and tasty this easy vegetarian and vegan-adaptable stew is perfect on chilly days. Packed with veg and pulses in a lightly creamy, garlic and thyme broth.
Put the olive oil and butter in a large saucepan over medium heat.
When hot, add the onion and celery, season with a pinch of salt and a good grind of black pepper.
Cook, stirring often, until the vegetables are starting to soften and colour (10 - 15 min).
Add the mushrooms and continue cooking until they are browned too (another 8 - 10 min: turn the heat up if necessary to brown them but remember to turn it back to medium again).
Add the potato, garlic and thyme then cook, stirring constantly for 1 minute: don't let the garlic burn.
Pour in the stock and milk then stir well, making sure you scrape up any veg from the bottom of the pot.
Bring to a boil (putting a lid on will speed this up but be careful it doesn't boil over) then immediately turn the heat to low and simmer with the lid on for 5 minutes.
Stir in the lentils and simmer for 3 minutes more.
Take the pan off the heat and very briefly whizz with a stick blender to puree just a little of the soup to thicken it.
Add the kale to the pan and continue cooking until done to your liking (5 - 10 min).
Taste, add more salt and pepper if needed, and serve.
Can be stored in the fridge for 3 days. Freezing not recommended as it can adversely affect the texture of the kale.
Note #1 Plant based version. Replace the butter with a little more oil.
Note #2 Amount of liquid. This makes a thickish stew. If you'd prefer it thinner, add an extra 100-150 ml of stock, milk, or a combination of the two.
Note #3 Variations. The stew is lovely served with a sprinkle of diced cheese to melt in. For a richer taste, you can also add a few tablespoons of double cream at the same time as the kale.
