Charred Green Beans with Lemon Verbena Pesto

This vibrant vegetarian side dish brings a sophisticated twist to classic seasonal greens. By charring slender green beans over a high flame, you achieve a smoky depth that perfectly offsets the bright, citrusy notes of the homemade lemon verbena pesto. It is a wonderful way to utilise aromatic garden herbs, offering a refreshing alternative to traditional basil-based sauces.

Ideal for summer entertaining or as a light accompaniment to a weekend lunch, this dish is as versatile as it is flavourful. The pesto can be prepared in advance and stored in the fridge, making this a quick and easy option for busy hosts. Serve these beans alongside grilled halloumi or roasted new potatoes for a healthy, Mediterranean-inspired feast that celebrates simple, fresh ingredients.

Ingredients for Charred Green Beans with Lemon Verbena Pesto

  • 675g slender green beans

  • 2 teaspoons olive oil

  • 1 cup fresh lemon verbena leaves (substitute fresh lemon balm leaves)

  • 2 garlic cloves

  • 40g grated Parmesan cheese

  • 60ml pine nuts or English walnuts

  • 120ml olive oil

  • Fine kosher or sea salt and freshly ground black pepper to taste

Prepare a hot fire in your grill.

Toss the beans with olive oil and place in a perforated grill basket or wok set on a baking sheet.

For the Lemon Verbena Pesto, combine the lemon verbena, garlic, cheese, and nuts in a food processor and pulse to puree. Slowly add the olive oil with the processor running until the mixture thickens and emulsifies, about 1 minute. Season to taste with salt and pepper. The pesto will keep in the refrigerator for 7 to 10 days or it may be frozen for up to 3 months.

Place the grill wok or basket directly over the fire and stir-grill tossing the beans with wooden paddles or grill spatulas until crisp-tender, about 5 to 8 minutes. Transfer the grilled beans to a large bowl and toss with about 60ml the Lemon Verbena Pesto or to taste.
