Potato & Celeriac Soup
1/4 cup oil, olive preferably
1 # yellow onions, small diced
3 cloves garlic, chopped
3 # potatoes, peeled and roughly cubed
2 # celeriac, peeled and rough cubed
2 quarts stock, chicken or vegetable
4 sprigs thyme, stripped
1-cup heavy cream (optional if you want a lighter soup)
Heat oil in soup pot. Add onions and sauté until slightly caramelized. Add garlic and sauté for one minute longer. Add potatoes and celeriac for one minute. Add stock and simmer until potatoes and celeriac are soft. Remove from heat. Using a blend stick or blender, process until smooth in small batches. If using a blender, initially pulse it so that it doesn’t splash upward. Transfer puree to a container. Continue until all is pureed. Add fresh thyme and heavy cream (if desired). Season with salt and pepper.
