Another tasty way to enjoy celeriac.
6-8 cloves garlic, minced
1 large onion, chopped
1 large celeriac, peeled and cubed
3-4 large potatoes, peeled and cubed
Chicken or veggie stock, or water
2-3 tsp dried sage (or more to taste)
Salt and pepper to taste
Heat some olive oil in a soup pot and saute the garlic and onions for 3-4 minutes. Add the celeriac and potatoes and enough water or stock to cover. Bring to a boil, then simmer until the vegetables are tender (how long this takes will depend on the size you cut them to).
When the vegetables are tender, puree the soup with an immersion blender (or in batches in a food processor). Stir in the sage, salt, and pepper.
