Lemon Balm Pesto Recipe

Lemon Balm Pesto.

The following recipe is a sneak peek excerpt from my debut book, The Healing Garden: Cultivating and Handcrafting Herbal Remedies, a detailed herbal reference, decadent cookbook, and garden manual all in one. This book is written for home gardeners and anyone looking to bring the therapeutic benefits of healing herbs into their garden, kitchen, and apothecary. You can purchase a copy of your own wherever books are sold. You can find more details on the book and its accompanying bonuses here.

Back in the day, when I ran an in-person herbal school, my students would pick one herb and give a presentation on its medicinal qualities along with a sample: a spot of tea, a taste of tincture, or sometimes a nibble of the plant. When a student told me she’d be preparing lemon balm pesto, I gave an encouraging smile, belying my apprehension. I am a decidedly adventurous eater, but this pesto felt wrong. Never have I been so happy to eat crow. 

On the day of her presentation, I had to politely hold myself back from seconds to let others have a go. When my team was recipe-testing for my book, this pesto emerged as one of the recipe testers’ all-time favorites. 

You’ll know just what to do with this pesto when you taste it. But to offer some starting points, may I suggest smothering it on broiled fish or rotisserie chicken. It holds its own snuggled up with pasta or even slathered on sourdough toast.

Lemon Balm Pesto Recipe

I recommend gathering lemon balm’s leaves earlier in the growing season when they are tender. Later in the summer, use only the young top leaves for pesto. Be sure to remove the leaves from the fibrous stem before adding them to the food processor. If you avoid cheese, substitute ½ cup nutritional yeast for the Parmesan. You’ll find this recipe in The Healing Garden book, along with a full profile on the cultivation & harvesting of lemon balm, and the medicinal uses of the herb.

      I think using dried would create an undesirable texture, unfortunately. Fresh herbs are really the best choice for making pestos. Hopefully you can grow lemon balm yourself or find some available locally to make this tasty recipe!
