I wonder if sautéing the onions first makes them a little more flavoursome atqui? However, my soup maker doesn’t have a sauté function and I just chop up whichever veg I have to hand, set it going and leave it to do it’s job, and find it to be very tasty. I suppose, though, that you could pre fry your onions in a little pan first before adding to the soup maker, but that creates extra washing up. If you don’t want extra washing up, but want to sauté the onion, then go for a soup maker with the sauté function. Sorry, I’m not being very helpful, really, am I? 😅
