Redroot pigweed (Amaranthus retroflexus), also known as pigweed amaranth, is a common summer annual herb. This plant is native to the tropical Americas, but it has been introduced to also every continent in the world. In the US, this plant is mainly used as livestock fodder, especially for hogs and pigs, hence its name. Other than that, this plant also grows in many farm fields and gardens. Due to its prolific growth and hardiness, some people regard this plant as a pesky weed.

This plain-looking plant may be a livestock fodder. But, that doesn’t mean that humans can’t enjoy it as well. In fact, this plant is considered a valuable vegetable in many parts of the world. For example, Native Americans, Mexicans, and Indians are known to include pigweed leaves in their traditional dishes. Moreover, this plant is well-known for being a great survival food due to its delicious flavor and its nutritional content.

Edibility and culinary use

Every part of the plant is edible, but the leaves are the most popular part. Pigweed leaves are eaten as vegetables in many parts of the world and they can be eaten raw or cooked. Harvest and eat only the young pigweed leaves. This is because as they get older, the leaves become bitter and tough. These leaves have a mild and neutral flavor that’s reminiscent of spinach. Due to their light flavor, pigweed leaves are often combined with herbs, spices, and other stronger-flavored leaves. Alternatively, you can also boil fresh or dried pigweed leaves to make an herbal tea.

As mentioned earlier, every part of this plant is edible, including its seeds. These seeds may be small, but they really pack a punch. The seeds have a pleasant nutty flavor that becomes even more delicious when they’re roasted. You can grind roasted pigweed seeds and use the powder as a thickener or a cereal substitute. You can also use the powder when making bread. Or you can also sprout the seeds and add them to salads.
