Yes, here's how to freeze cabbage: 1. Remove the outer leaves (they're very tough) and rinse under running water. 2. Cut the cabbage into wedges. 3. Drop the wedges into boiling water and cook for 3 minutes. 4. After 3 minutes, immediately submerge in ice water. 5. Once cool, thoroughly pat dry. 6. Seal inside a freezer bag, label, and freeze for up to nine months.
