Some days, soup is what’s needed for dinner. It’s comforting, a lovely bowl of goodness that gives you a hug. This delicious mushroom soup topped with crispy croutons is just that!
My husband is a proud Yorkshire man and was brought up on a diet of all things Yorkshire, all of which he was delighted to introduce me to when we started dating. One of the foodstuffs he most loves is Hendersons Relish. I’d never heard of this before I met him, so there’s a good chance you may not have either. It’s like Worcestershire Sauce (don’t hate me, Yorkshire people), in that has an intense, savoury richness which adds an incredible umami flavour to any dish. Yorkshire people particularly like their pies slathered with it – and with good reason.
When we decided to try out a plant based diet some time ago, deep, savoury flavours were the ones I thought I’d miss the most. However, on making this mushroom soup, I discovered that this does not necessarily need to be the case. I found, quite by chance, that Hendersons Relish (unlike Worcestershire Sauce) is vegan friendly. Woo!
This earthy soup is a wonderful warmer for lunch, as a starter, or with a fat hunk of sourdough, a satisfying dinner. Enjoy!

Ingredients, Substitutions and Variations
- Olive oil – you’ll use this to start the soup and fry the croutons. You could switch for vegetable oil.
- Onion and garlic– required for a flavour hit! Use white or yellow onions.
- Mushrooms – you can use any kind of mushrooms you like. Chestnut, woodland and shiitake are flavourful and work well here, but any will do.
- Vegan stock cube and water – or use 600ml homemade vegetable stock if you have some to hand.
- Hendersons Relish – this soup is at its best when you use this! If you’re not vegan, you can use Worcestershire sauce instead or, alternatively, to keep it vegan, use 1tbsp soy sauce, 1tbsp mirin and 1tsp tamarind paste.
- Whole grain bread – you can use white if you prefer.
- Chives – optional
Top Tips
- Roughly chop As this soup will be blended, don’t waste time finely chopping your onion and mushrooms. Rough is fine.
- Blend until smooth You can control the texture of your soup. If you prefer some chunks in your soup for a bit of bite, only blend half.
- Keep an eye on your croutons They don’t take long and can burn easily!
