This root vegetable soup can be quickly made in one pot on the stovetop, or the medley of vegetables can be roasted together with the aromatics before being blended into a dreamy creamy soup. Good for you, naturally vegan and gluten-free.
Root Vegetable Soup
This simple soup is at its best during the winter and spring months when root veggies are in season. Healthy and hearty, the flavor profile is a perfect balance of savory sweetness and earthiness. I love it pureed into a silky perfection in my Vitamix, but it can be kept chunky and finished with a heavy pouring of cashew cream, more like a chowder.
The Root Vegetables for Soup
- Onion or Leek – Onions are probably the most common root vegetable and it works great as a flavor base for this soup. If i happen to have leeks handy i tend to prefer those, just make sure to slice and rinse them well. Use only the white and pale green parts or it will affect the golden color of your soup.
- Celery Root or Turnip – I love celery root, it simply makes a soup better. It’s important that you use the right amount, about one cup of diced celery root is perfect here. If for whatever reason you dislike the taste just use more celery stalks instead or swap for a turnip which is a milder vegetable.
- Carrot – Adding sweetness and balancing out the earthiness of the other veggies. Peel first for brightest color. If desired a baseball size golden beet root can be used instead.
- Parsnips – They look like a cream colored carrot and are a member of the parsley family but with a milder flavor. They can be swapped with a parsley root, remember to peel them both.
- Potatoes – Golden potatoes are my favorite, rinse and chop, no peeling required so less work and more nutritious.
- Thyme or Rosemary – Choose your favorite here or combine them. I used about 12 sprigs of thyme but you can use 2-3 rosemary sprigs depending on how intense of a flavor you are after.
- Cashews – totally optional but they do help thicken the soup naturally while giving it a luxurious silkiness.
- Variation – Go for a spiced version of this soup with a couple of inches of both turmeric and ginger root root + up the garlic. Or give it some Italian flair by adding a fennel bulb into the medley.
- Add Ins – for a heartier meal serve with some cooked beluga lentils mixed in, wild rice, barley or farro. Top with roasted broccoli or cauliflower florets, sweet potato cubes or torn up pieces of garlicky Italian bruschetta. To boost your antioxidant and micronutrient content wilt in a bunch of dark leafy greens like baby kale, spinach, dandelion or mustard greens.
- Storage – This soups keeps well in the refrigerator up to a week and since it’s dairy-free it can also be frozen in lidded containers up to 4 months. Thaw out in the fridge before reheating on the stovetop or microwave oven.
