Many popular root vegetables like potatoes, carrots, and parsnips are surprisingly high in carbohydrates, which is problematic for anyone following a keto or low-carb diet. The good news is that several delicious and versatile root vegetables are naturally low in carbs and can serve as excellent alternatives in a variety of dishes.
The Best Low Carb Root Vegetables
Radishes: The Unexpected Low-Carb Gem
Radishes are a standout for anyone looking for extremely low-carb options. Typically served raw in salads, they can also be roasted, which gives them a mild, sweet flavor and a soft, potato-like texture. With just about 2 grams of net carbs per cup when sliced, radishes are highly versatile and can be used in a variety of cooked dishes as a substitute for higher-carb vegetables.
Turnips: A Versatile Potato Substitute
Turnips offer a classic potato-like texture when cooked, making them a popular substitute for mashed potatoes or roasted root vegetables in low-carb cooking. A medium turnip contains only about 5.8g of net carbs, making it a very keto-friendly choice. They are also rich in fiber and various vitamins, including K, A, and C, adding nutritional value to your meals. Mashed turnips, roasted turnips, or added to soups are all great ways to enjoy this vegetable.
Celeriac (Celery Root): A Buttery, Nutty Flavor
Celeriac is known for its earthy, nutty flavor and is another great option for low-carb diets. With about 7.4g of net carbs per 100g, it can be mashed, pureed, or roasted to create a delicious and satisfying side dish. Its texture makes it an excellent base for a velvety, low-carb puree that rivals mashed potatoes. Celeriac is also a good source of vitamins B6, C, and K, as well as minerals like potassium.
Rutabagas: A Hearty Low-Carb Option
Rutabagas, a cross between a turnip and a cabbage, offer a slightly sweeter, milder flavor than turnips. They are another excellent low-carb alternative to potatoes and can be mashed, roasted, or sautéed. At around 6 grams of net carbs per 100g, they provide a filling and comforting option for those watching their carb intake.
Practical Tips for Cooking with Low-Carb Root Vegetables
- Mashed Alternatives: For creamy mashed potatoes, try using a combination of celeriac and turnips. Boil until tender, then mash with butter, cream, and your favorite seasonings.
- Roasted Veggies: Slice radishes, turnips, and rutabagas, toss with olive oil and herbs like rosemary and thyme, and roast them in the oven until tender and caramelized.
- Soups and Stews: Add celeriac, turnips, or radishes to soups and stews for a heartier, low-carb base. Celeriac, in particular, adds a distinct, delicious flavor.
- Fries: For a low-carb alternative to french fries, cut celeriac or rutabaga into sticks, toss with oil and spices, and bake until crispy.

It’s all about knowing your options and experimenting with what works best for your taste buds and dietary needs. The key is mindful consumption and portion control, especially with vegetables that have slightly higher carb counts.
