This was the first course to my 6-course Friendsgiving party for 3 people.
I think I saw this in Bon Appétit Magazine two years ago and I thought that I would use it this year. It was originally going to be on last year’s menu but I ran out of time.
For the Soup
- ¼ cup butter (half stick)
- 3 large leeks, white & pale green parts only
- 1 large onion, thinly sliced
- ½ head garlic, thinly sliced
- 1 cup whole milk
- ½ cup heavy cream
- ½ cup plain yogurt
- Salt & freshly ground black pepper
Slice leeks in half lengthwise, wash out the sand/dirt and thinly slice crosswise.
Melt the butter in a pot over medium heat. Add and sweat the leeks, onion, and garlic, and season with salt. Stirring often, cook until the vegetables begin to soften. Add ½ cup water and cook, stirring occasionally, until vegetables are very soft, 15–20 minutes.
Turn off heat and add the milk, cream, and yogurt. Using an immersion blender, blend until smooth. Turn heat back on and adding water, by ¼-cupfuls, until the soup is thick enough to hold potatoes without sinking but thin enough that a spoon dragged across the top doesn’t leave a trail. Adjust seasoning with salt and freshly ground black pepper.
For the Finish
- 1 Idaho potato
- Vegetable oil, for frying
- 4 flat-leaf parsley sprigs
- 2 basil sprigs
- Chive oil
Peel potato and cut into thin matchsticks. Rinse potato in a colander under cold water until water runs clear; pat dry completely. Pick all the herbs and set aside.
Fit a medium saucepan (with thermometer) and pour in oil to measure 2”. Heat over medium-high until thermometer is at 350°F. Working in batches and returning the oil to 350°F between batches, add potato by the handful and fry until golden and crisp, about 2 minutes. Using a spider, transfer potatoes to paper towels to drain. Fry herbs until parsley is translucent, about 15 seconds. Season with salt after each batch.
For extra crispiness, place in dehydrator or 110°F oven.
Serve soup topped with a nest of potatoes and herbs, and a drizzle of chive oil.
