Quick Answer
To prepare cattail for eating, harvest the rhizomes or roots in the spring or fall when they are tender, wash and peel them, then boil or roast them to make a starchy, slightly sweet food source. The shoots and flowers can also be eaten raw or cooked.
Harvesting Cattail Rhizomes
To prepare cattail for eating, start by harvesting the rhizomes, which are the underground stems that store energy for the plant. Dig carefully around the base of the plant in the spring or fall when the rhizomes are tender, then use a long-handled shovel or trowel to carefully remove them from the ground. Avoid damaging the rhizomes, as this can cause them to rot.
Preparing Cattail for Cooking
Once you have harvested the rhizomes, wash them thoroughly to remove any dirt or debris. Peel the rhizomes using a vegetable peeler or a sharp knife, then chop them into small pieces. The rhizomes can be boiled, roasted, or dried to make a starchy, slightly sweet food source. To boil, place the chopped rhizomes in a pot of water, bring to a boil, then reduce heat and simmer for 15-20 minutes. To roast, place the chopped rhizomes on a baking sheet and roast at 350°F (180°C) for 20-25 minutes, or until tender.
Eating Cattail Shoots and Flowers
The shoots and flowers of the cattail plant can also be eaten raw or cooked. Harvest the shoots when they are young and tender, or wait until the flowers have formed and are still green. Simply snip off the shoots or flowers with scissors or a knife, and use them in salads, as a garnish, or as a side dish. The shoots and flowers can also be sautéed or boiled like the rhizomes.
