Add broth and bring soup to a boil. Reduce heat to medium-low. Simmer until all vegetables are tender, about 20 minutes. Working in batches puree cooled soup in a blender ( or use a hand emulsifier in the pot). Return puree to pot. Season with salt and pepper. (Can be made 1 day ahead. Refrigerate uncovered until cold. Cover and keep refrigerated).

Since my family is Welsh by heritage, we eat leek soup on St. David's Day, March 1st, every year as a tradition. I was so happy to find this recipe this year because it uses vegetable broth instead of chicken broth (I no longer eat meat.) I thought the soup would lack something without the traditional chicken stock, but was absolutely delicious! (Some tips: I found it only needed FOUR cups of broth, which made it nice and thick. I also substituted half the olive oil for fresh butter for a richer, creamier taste. Then I added a dash of white pepper, a flavoring many other leek soup recipes call for. For the cheese toasts I used a combo of cheddar and gruyere too, because that's what I had in my fridge at the time. It was excellent.)

The savory soup combined with the crusty sourdough garlic cheese toast is a perfect and very satisfying meal. Best of all, it was really simple and straightforward to make. I'll be making this next year for sure!

Very tasty, subtle soup. We found that the potato flavour dominated. I used chicken stock, instead of vegetable. Also, I'd recommend making a day ahead as the flavours really intensify overnight. I used Gruyere cheese for the toasts, and they were fantastic! Thanks Chili Spice!

This is a very nice change from my usual vegetagle soups, & easy to prepare! Although I used the ingredients as suggested (did use vegetable broth), I pureed all but about a cup of of finely diced/chopped onion, potato & leek, which made for a chunkier finished product! However, the taste was there, & it was great! Many thanks for sharing the recipe! [Made & reviewed as a tagged bonus recipe for one of my invitees to the AUS/NZ Recipe Swap #14, Mar 08]
