What Are Celery Roots? Unearthing the Knobbly Delight
Celery root, also known as celeriac, is a versatile and underappreciated vegetable that is cultivated specifically for its large, edible bulb and provides a subtly celery-flavored alternative to other root vegetables.
Introduction: Beyond the Stalk – Exploring the Celery Family Secret
Many are familiar with celery stalks, the crunchy addition to salads and snacks. But fewer know its cousin, celery root, also called celeriac. This bulbous vegetable, often overlooked in the produce aisle due to its gnarled appearance, is a culinary treasure waiting to be discovered. Celery root is not simply the root of the celery stalk we eat; it’s a different variety of the same plant, Apium graveolens, bred specifically for its swollen, edible root. Its flavor is similar to celery but with earthy, nutty undertones, making it a versatile ingredient in a variety of dishes.
Background: From Wild Ancestor to Culinary Star
The history of celery and celery root is intertwined. Both originated from a wild plant, Apium graveolens, found in the Mediterranean region. While the celery stalk was initially prized for its medicinal properties, celery root emerged as a cultivated variety prized for its edible bulb. Selective breeding over centuries led to the development of the large, round celeriac we see today. It’s been a staple in European cuisine for centuries and is gaining popularity in North America and elsewhere as chefs and home cooks alike discover its unique flavor and versatility.

From Garden to Table: Growing and Harvesting Celery Root
While growing celery root can be a bit more challenging than growing celery stalks, the reward is a delicious and unique vegetable.
- Start seeds indoors: Celery root needs a long growing season, so start seeds indoors 8-10 weeks before the last frost.
- Transplant seedlings: Once the seedlings are large enough, transplant them into well-drained soil with plenty of sunlight.
- Consistent watering: Keep the soil consistently moist, especially during dry periods.
- Hilling: As the bulb develops, hill soil around it to protect it from sunlight and promote even growth.
- Harvesting: Harvest celery root in the fall, after the first frost. The flavor improves after exposure to cold.
Culinary Canvas: Cooking with Celery Root
Celery root’s mild, celery-like flavor lends itself to a variety of culinary applications. It can be enjoyed raw, cooked, or pureed.
- Raw: Grated into salads or coleslaws for a crunchy, flavorful addition.
- Roasted: Cut into cubes and roasted with other root vegetables for a savory side dish.
- Mashed: Pureed into a creamy, comforting alternative to mashed potatoes.
- Soups and Stews: Added to soups and stews for depth of flavor and texture.
- Gratins: Sliced thinly and layered in gratins with cheese and cream.
Avoiding Common Pitfalls: Preparation Tips and Tricks
Working with celery root can be intimidating due to its rough exterior. However, with a few tips, you can easily prepare it for cooking.
- Thorough cleaning: Wash the bulb thoroughly to remove any dirt or debris.
- Peeling: Use a sharp knife to carefully peel away the tough outer layer. A vegetable peeler won’t work well on this.
- Oxidation: Celery root oxidizes quickly once peeled, so immerse it in water with a squeeze of lemon juice to prevent browning.
- Proper storage: Store unpeeled celery root in the refrigerator for up to two weeks. Peeled celery root should be used immediately or stored in water.
