Garlic Mustard: The Perfect Food to Forage

Though I do a lot of gardening, I can’t help but love foraging. I don’t have to do any work, and wonderful plants like chickweed, dandelion, and plantain appear!

Most wild foods are carefree, too, so plant diseases and garden pests leave them alone. Unlike some beloved garden plants (cabbage worms, I’m looking at you).

Garlic mustard is one of these carefree wild plants. Nothing bothers it. But there’s another reason you can forage as much of it as you’d like. It’s highly invasive.

Garlic mustard is an invasive species, so you can forage it freely.

Native to Europe, garlic mustard was brought to North America by early settlers who likely used it for food and medicine. But as often happens with non-native species, garlic mustard took off.

Now, it tends to choke out native plant species because there aren’t enough local species to keep it under control.

Except for people. Garlic mustard is completely edible and actually quite delicious. It’s easy to identify, plentiful in most woodland areas, and nearly impossible to eradicate. You couldn’t ask for a better plant to forage!

Help your native ecosystem and enjoy some fresh, seasonal deliciousness by learning how to forage for garlic mustard. The yummy garlic mustard pesto recipe coming up will help you learn to love this tasty wild food.

How to Find and Identify Garlic Mustard

Garlic mustard is a great starter plant for beginner foragers. While some plants have bad-tasting lookalikes, or worse yet, dangerous ones, garlic mustard isn’t like that. All it takes is a little practice to become a garlic mustard foraging pro.

But even though it’s easy, you still want to observe some basic foraging guidelines and make sure you can positively identify garlic mustard.

Where Garlic Mustard Likes to Grow

Before you start looking for garlic mustard, check on two important questions:

  • Do I have permission to forage here?
  • Is this land contaminated with any pesticides, chemicals, or hazardous waste?

Obviously, both of these are easy to answer if you’re harvesting on your own property. But if you’re not, you need to settle them before you proceed.

Garlic mustard likes to grow in woodlands and along wooded roadways. In fact, in the springtime, you can easily find entire roadway edges cluttered with garlic mustard. However, this isn’t a good place to harvest due to contamination from vehicle exhaust, salt and deicers, and other chemicals.

I find garlic mustard on our small property around the base of trees and large bushes. When I spy one tall stem of it, there are usually a few more nearby.

If you can’t find garlic mustard on your own property, check with local nature centers, park systems, and preserves. These organizations often need help removing garlic mustard so native species can thrive. When you forage for it, it’s a win for you and a win for the park system!

Garlic Mustard Identification & Harvesting

When foraging, it’s crucial that you positively identify a plant before eating it. Garlic mustard is easy to correctly identify, though. Even if you’ve never harvested a wild plant before, you can identify garlic mustard.

When foraging for garlic mustard, second-year plants are easiest to identify. In the early to middle spring, look for 

  • Tall, single, unbranched stems around 1-2 feet tall (though some ambitious plants can grow much taller).
  • Small white flower clusters with 4 petals on each flower towards the top of the plant.
  • Triangular leaves with noticeable veins and deeply toothed edges that grow up the stem.
  • Bright green color.
  • Thin seed pods where flowers were previously if you’re harvesting later in the spring.

First-year plants are a bit harder to identify if you’re new to garlic mustard. The leaves look like kidneys and are more heart-shaped than triangular. They also won’t grow from a tall stem. Instead, the plant grows in a rosette close to the ground, reaching around 6 inches tall.

For more helpful photos and identification tips, check out this garlic mustard article from the Ohio State University.

Whether you’re harvesting first- or second-year plants, the giveaway for garlic mustard is the smell. The stems, leaves, and flowers smell like (take a guess…) garlic. If you aren’t sure if you’ve found garlic mustard, just crush some of the plant in your hands and give it a sniff. If it has a mild garlic scent, you’ve got a winner.

The best plants to harvest for food are mature first-year rosettes or young second-year plants. Like everything in the mustard family, the plant tends to get bitter as it ages.

Harvest by pulling the whole plant out by the roots. You can usually get the entire root out easily. Be careful not to scatter more garlic mustard seed while you forage since it likes to take over.

Unlike most other foraged plants, you don’t have to worry about overharvesting garlic mustard. Take as much as you’d like!

Yikes! Is Garlic Mustard Poisonous?

Even if you’re interested in using garlic mustard, you might have a lingering worry:

Does garlic mustard contain cyanide?

I’d eaten garlic mustard for years before I came across this concern. And as it turns out, yes, garlic mustard contains a cyanogenic compound

But before you panic, there are a few important things to remember.

  • This compound is most concentrated in young, first-year leaves.
  • You have to regularly ingest a lot of garlic mustard for this to potentially be a problem.
  • And if you’re really worried, cooking should eliminate the cyanide concern, just like it does for elderberries when you make homemade elderberry syrup.

Other edible foods contain small amounts of cyanogenic compounds, like almonds, cassava, and stone fruits. But when you eat them in normal amounts and include them in a balanced diet, you don’t suffer any ill effects. So it is with garlic mustard.

Yummy Garlic Mustard Pesto Recipe

Hands down, my favorite way to eat garlic mustard is in this delicious pesto recipe. It tastes surprisingly similar to traditional basil pesto and you can use it in the same way.

You can also add some fresh basil, young dandelion greens, or other herbs along with the garlic mustard if you’d like. I usually only use garlic mustard, but adding other green herbs gives you an opportunity to tweak the flavor to your preferences.

  • 1 cup washed and drained garlic mustard leaves, moderately packed
  • 2 tablespoons other fresh herbs, like oregano, basil, or thyme (optional)
  • 1 large garlic clove
  • 1/4 cup shredded Parmesan cheese
  • 2 tablespoons toasted sunflower seeds (you can also use almonds, walnuts, or the traditional pine nuts)
  • 1/2 teaspoon salt (I love Redmond Real Salt)
  • Dash black pepper
  • 1/2-1 cup extra virgin olive oil
A food processor makes mixing up a foraged garlic mustard pesto fast and easy


  1. Place all ingredients, using 1/2 cup of the olive oil, in a food processor.
  2. Turn on and process until smooth. You may need to stop and scrape the sides of the bowl once or twice.
  3. Check the consistency of your pesto and add more oil if desired, pulsing the processor to combine. I like this with a full cup of oil.
  4. Use as you would traditional pesto and store any leftovers in the fridge.

This makes about 1 cup, depending on how much oil you use.

Sometimes gardening isn’t possible. Even when it is, gardening doesn’t always end up as you hope. Despite your best efforts, cabbage moths are really good at laying eggs in your kale.

But cabbage worms don’t bother garlic mustard.

Foraging this wild green and turning it into garlic mustard pesto lets you enjoy fresh food from the backyard with little work on your part. And native plants will thank you for removing it and giving them extra room to thrive!

    1. I got a huge swath of garlic mustard between my house and the neighbors. It just appeared this year.
      I have already made more than 10 pints of your delicious pesto, and the plant is far from gone.
      The recipe is so versatile, and everybody seems to love it.
      I mostly add dandelion leaves as the “other herbs”, and sometimes I skip the garlic. The taste is incredibly fresh, even after a couple weeks in the fridge.
      Thank you so much.

      1. That’s awesome, Michael! Thanks so much for taking the time to let me know the pesto has been a hit for you. And isn’t it crazy how quickly garlic mustard can take over?

    2. This is great! I think I’ve seen this plant and now I’ll watch for it. I discovered last year that you can eat hosta shoots in the spring and that they come back just fine. I had some hostas in a bed I wanted to use for vegetables. I was about to dig them out and throw or give them away and had a thought to double check their edibility. Lo and behold, they’re edible and delicious. Kind of similar to asparagus without the years of waiting on a new asparagus bed.

      1. Yes, I’ve heard that about hostas! I haven’t tried them yet since moles killed off a lot of ours, little rascals. Our family doesn’t really like asparagus (I know, I know…) but I wondered what we’d think about hosta shoots. Isn’t fun to find new foods from your own yard?

    3. I have just become interested in foraging and this weed is prevalent in my area. It seemed like a great place to start my foraging. That is until I read, in several places, that the garlic mustard plant leaves contain cyanide. Yeeps! Any thoughts on this?

      1. Hi Karen! That was new information to me, but yes, seems correct. I wouldn’t be concerned unless you plan to eat bowlfuls of it daily. Lots of plants we eat will have trace amounts of compounds that are harmful when isolated and taken in large amounts. Feel free to enjoy some added to recipes if you’re comfortable trying them still. 🙂

    4. Garlic mustard is a VERY invasive weed.
      Do not, under any circumstances, plant this.
      It WILL take,over!

      1. That’s good to know, Bob. Thank you!

        The thought of planting it never crossed my mind since I see it in so many places, but that is a helpful tip to note. We’ll stick to foraging for it! 🙂
