Tips & Variations

- For extra brightness, add a sprinkle of freshly grated lemon zest to the salad before serving.
Storage

FAQs
Can I use frozen green beans for this salad?
While fresh green beans offer the best texture and flavor, you can use frozen beans if fresh aren’t available. Thaw and pat them dry before blanching, but be careful not to overcook as they tend to be softer.
Can I make the pesto ahead of time?
Yes, you can prepare the pesto a day in advance and store it in an airtight container in the fridge. Give it a good stir before tossing with the green beans to refresh the flavors.

Ingredients
Green Beans
- 1 ½ lbs green beans, trimmed and cut into 1-inch pieces
Herb Pesto
- ¼ cup walnuts, toasted (alternatively almonds, pistachios, or cashews)
- 1 bunch dill, roughly chopped without stems
- ½ bunch parsley, roughly chopped without stems
- 1 clove garlic
- ⅓ cup olive oil
- 1 tsp kosher salt
- 1 lemon, divided and juiced
- 1 tsp red wine vinegar
- 1 tsp Dijon mustard
Instructions
- Prepare the Herb Pesto: In a food processor, combine the toasted walnuts, olive oil, juice of half a lemon, and garlic. Blend until smooth.
- Add Herbs and Seasoning: Add the chopped dill, chopped parsley, red wine vinegar, Dijon mustard, and kosher salt to the processor. Blend again until the mixture is smooth and well combined.
- Prepare an Ice Bath: While the green beans chill after cooking, fill a large bowl with ice and cold water to create an ice bath for shocking the beans.
- Cook the Green Beans: Bring a large pot of water to a rolling boil. Add the trimmed and cut green beans and cook for 2 minutes until crisp-tender.
- Shock the Beans: Immediately transfer the cooked green beans to the ice bath using a strainer or tongs. Let them chill for 5 minutes to stop cooking and preserve their bright color.
- Dry the Beans: Remove the beans from the ice bath and pat dry thoroughly with a paper towel to prevent diluting the pesto.
- Toss with Pesto: Place the dried green beans in a large bowl, add the herb pesto, and toss to coat evenly.
- Finish and Serve: Squeeze the remaining juice of the lemon over the salad, sprinkle with flaky salt to taste, toss again, and transfer to a serving dish. Serve immediately for the best flavor and texture.
Notes
- Any nuts like almonds, pistachios, or cashews can be substituted for walnuts in the pesto.
- Ensure green beans are patted dry well after the ice bath to keep the pesto from getting watery.
- The salad is best served fresh but can be refrigerated for up to 1 day; bring to room temperature before serving.
- For a nuttier pesto, consider lightly toasting the herbs in a dry skillet before blending.
