Benefits of Lemon Balm:
Lemon balm (Melissa officinalis) isn’t just a flavorful herb—it also offers numerous health benefits:
- Reduces stress and anxiety: Studies have shown that lemon balm may help reduce cortisol levels and promote calmness.
- Supports digestion: It has natural carminative properties that ease bloating and indigestion.
- Boosts cognitive function: Some research suggests lemon balm can help with focus and memory.
- Rich in antioxidants: Helps fight oxidative stress and supports immune health.
- Antiviral properties: Traditionally used to help with colds and viral infections.

Tools:
- Food Processor
- Silicone ice cube tray (for freezing)

Ingredients:
- 2 cups fresh lemon balm leaves
- 2 cups fresh basil leaves
- 1/3 cup Parmesan cheese (cut into cubes)
- 1/4 cup pine nuts or cashews
- 1/2-1 cup extra virgin olive oil
- Salt and pepper to taste
How to make Lemon Balm Pesto Sauce:
- Add all ingredients except for the olive oil to a food processor.
- Pulse until coarsely chopped.
- While pulsing, slowly drizzle in olive oil until smooth.
- Add salt and pepper to taste. Pulse again to combine.
- Freeze any leftovers in silicone ice cube trays or freezer-safe containers

Tips:
- Mix herbs: Blend lemon balm with basil or parsley for a more complex flavor.
- Try different nuts: Almonds, cashews, or sunflower seeds make great nut-free or allergy-friendly alternatives.
- Use high-quality olive oil for the best flavor.
- When refrigerating leftovers, seal the pesto by pouring a thin layer of olive oil on top after transferring the pesto to your storage dish. This will help prevent browning when stored in the refrigerator. Brown pesto is not as appetizing.
Recipe FAQ:
Q: What does lemon balm taste like?
A: Lemon balm has a mild lemony flavor with a hint of mint. It’s less pungent than basil and adds a bright, citrus-forward note to dishes.
Q: Can I substitute lemon balm for basil in any pesto recipe?
A: Yes, but the flavor will be lighter and more citrusy. You can also blend both herbs for a balanced flavor.
Q: How can I use lemon balm pesto?
A: Toss with pasta, spread on sandwiches, mix into salad dressings, drizzle over grilled veggies, or serve with fish or chicken.

I love this recipe! Lemon balm is one of my favorite herbs, and I use it a lot for tinctures, teas and salves. I’ve added a little to pesto in the past combined with other herbs. It’s so useful and has so many health benefits. Never thought to make a pesto with just lemon balm, but I can see how that would really delicious. I’ll have to try that sometime.
