I bought leeks last week for potato soup and I also had almost eight ounces of mushrooms in the fridge that I needed to use. But instead of making two soups, I put them together and came up with this one.
First, I took the outer leaves off the leeks and after removing the root end I cut them into super thin slices. I put the slices in a colander ran water over them while separating the rings to be sure and get all the dirt from between the layers. Leeks are part of the family of onions and, while similar to onions, they have a milder flavor. I like the flavor they give my soups and stews, and I was also happy to see them on this website as one of the World's Healthiest Foods.
When I was satisfied the leeks were clean, I put them in a three quart sauce pan over low heat. I added a splash of olive oil and stirred it into the leeks. While the leeks started to saute, I washed and sliced the mushrooms, saved a few of the best for garnish and added the rest of the mushrooms to the pan.
When the leeks were soft and the mushrooms had given up their liquid I added some white wine, just to cover the veggies, and let it continue to cook while I peeled the potatoes. I cut the potatoes into medium chunks and put them in the pan with the leeks and mushrooms. I added water* to just barely cover the potatoes and turned up the heat.
*NOTE: I usually use chicken broth instead of water, or at least water with chicken bullion, but my son is dating a vegetarian, and has agreed to try it for a month. He was coming over later in the day, so I made this vegetarian for him. I didn't mention the mushrooms though. He insists he doesn't like them. Shhhh...
It wasn't long before the potatoes were fork tender. I turned the heat down and used a potato masher to break it all into smaller pieces. Next I got out my immersion blender and used it to turn the potatoes and mushrooms into a thick puree. I seasoned the soup with salt and pepper and my own garlic rich Janz herb blend. It very thick so now I added milk. I poured in a little at a time and stirred it in until it was the soupy consistency I was looking for.
When I was ready to eat, I filled a bowl and garnished it with a small dollop of sour cream, several super thin slices of carrots (I used a potato peeler to get them paper thin), fresh mushroom slices and a sprinkle of green onions. I am a pepper fiend so I had to add fresh cracked pepper to the top.
When my son arrived, I garnished his soup with carrot slices and grated Jarlsberg cheese. Other possible garnishes include avocado slices, grated Parmesan, seasoned croutons, and crumbled bacon.
