Lunch One pot Recipe Soups Starter Vegetarian Instant Pot leek and potato soup Michael Catling12 June 2025048 views When the mug variety doesn’t quite cut it, batch cook this classic vichyssoise (leek and potato soup) in your Instant Pot for a cosy working lunch. Cards on the table: I don’t like leeks. I’m not even a massive fan of potatoes (shock horror), but combine the two in a soup and I’m licking the bowl clean. My healthy version of the classic vichyssoise is the epitome of simplicity: seven ingredients, one pot and no hands-on cooking whatsoever. Just bundle everything in your Instant Pot, click the soup function, and leave it to do its thing for 30 minutes. A quick whizz with a hand blender is all it takes to thicken the soup and produce a gorgeous, velvety consistency. Serve with a drizzle of extra-virgin olive oil and a hunk of sourdough, and you’ve got a super cheap lunch sorted for the next few days.
