Celeriac is a versatile, cool-season root that can last well beyond the garden season if preserved properly. Over decades of gardening in Sonoma Valley, I’ve explored multiple preservation methods to enjoy its sweet, nutty flavor year-round. Each method has its advantages, and choosing the right one depends on how you plan to use the celeriac later.

Freezing Celeriac

Freezing is a great way to preserve celeriac for soups, stews, and purees. Here’s my approach:

  1. Peel and Slice: Remove the tough outer skin and cut roots into cubes or thin slices.
  2. Blanch: Boil the pieces for 3–4 minutes, then immediately plunge into ice water to stop cooking.
  3. Dry and Pack: Pat dry, place in airtight freezer bags, and remove excess air.
  4. Label and Freeze: Properly frozen celeriac can last 8–12 months while maintaining flavor and texture.

Drying Celeriac

Drying is ideal for adding celeriac to soups, stews, or vegetable powders. In my experience:

  • Peel and Slice Thin: Uniform slices dry more evenly.
  • Use a Dehydrator or Oven: Dry at low heat (around 125°F) until completely dry and brittle.
  • Store Properly: Keep dried celeriac in airtight jars in a cool, dark place for up to a year.

Long-Term Storage (Cellar or Refrigerator)

Some gardeners prefer storing fresh roots for months:

  • Cellar Storage: Keep celeriac in slightly damp sand or sawdust at 32–40°F. Roots can last 3–4 months.
  • Refrigeration: In perforated plastic bags in the crisper drawer, fresh celeriac can last 6–8 weeks.

Tips From Experience

  • Avoid storing wet or damaged roots—they spoil quickly.
  • Label all preserved celeriac with the date to track freshness.
  • Smaller, uniform roots preserve more effectively than oversized or irregular ones.

Bottom Line

Whether freezing, drying, or storing fresh, celeriac can be preserved successfully for months. Proper handling ensures maximum flavor, texture, and nutrition all year round.
