Garlic mustard pesto is a great beginner recipe for new foragers and one of the early spring plant species that starts the foraging season in my area. Unfortunately, garlic mustard isn't going away anytime soon. It's one of the most invasive weeds in North America and has been identified as a weed in almost every state.

However, this bitter herb has gained popularity as an herb and condiment because of its distinct taste caused by glucosinalin, which some have compared to horseradish.

This post shares a bit about this invasive but delicious invasive plant, where to find it, and how to use it!

What is Garlic Mustard?

Garlic mustard (Alliaria petiolata), also known as jack-by-the-hedge, hedge garlic, sauce alone, garlic root, garlic work, and mustard root, is a biennial flowering plant in the mustard family (Brassicaceae).

It is native to Europe, western and central Asia, and northwestern Africa, from Morocco and Iberia east to western Siberia. Still, it is considered an invasive species in many locations outside its native range.

How to identify, find, and identify garlic mustard

Garlic mustard grows throughout the United States, Canada, and Europe. It's a common plant that's pretty easy to find, particularly in wooded areas. However, if you live somewhere the plant is rampant, you can head out into your backyard and probably find it there.

A great way to find garlic mustard is simply to follow your nose. Garlic mustard has a distinct garlic-like aroma, which carries on the breeze like perfume. Walk around for a few minutes with your face tilted toward the wind, and you're almost guaranteed to sniff out some garlic mustard. The nose knows!

Once you know what you're looking for, it's easy to identify garlic mustard by its leaves. In springtime, the plant is topped with a cluster of heart-shaped leaves serrated like lettuce.

These leaves grow from a single stalk with purple flowers on top; later in the season, the flowers produce seeds that fall off on their own or are dispersed by the wind.

Once they fall off, they spread and can take root almost anywhere they land — including your garden! Once garlic mustard plants establish themselves in an area, it's tough to eradicate. The whole plant is edible, depending on what time of year you harvest it.


  • Chopped and blanched garlic mustard greens
  • Extra virgin olive oil
  • Toasted Pepitas
  • Garlic cloves
  • Parmesan cheese
  • Kosher salt, to taste

Expert tips for catering wild garlic mustard

The best time to look for these wild edibles is in mid-spring when the leaves are tender and just starting to unfurl. They have a milder flavor at this stage than during the summer when they get tougher and can be slightly bitter.

The stems are tender at this stage, so don't throw them away when you're making your pesto!

Gather the young leaves from the top of the plants. Don't use flowers or leaves from the bottom of the plant. Flowers are not edible, and older leaves can be tough and bitter.

Cut off any tough stems with a sharp knife, and rinse the leaves under cool water. Shake them dry, or lay them on a towel to absorb moisture.

Place the leaves in a large salad spinner or colander to dry completely. This can take a few hours, so be patient - wet pesto is not very good!

When the leaves are completely dry, they are ready to be used in your favorite recipe.
