Ingredients
  

Ingredients
  • 1 pound fresh green beans, ends trimmed
  • 1/2 cup fresh basil leaves, packed
  • 2 cloves garlic
  • 1/4 cup pine nuts or walnuts
  • 1/4 cup grated Parmesan cheese
  • 1/4 cup olive oil
  • 1 tablespoon lemon juice
  • Salt and pepper to taste
  • Optional: 1 tablespoon butter for extra richness

Method
 

Instructions
  1. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
  2. Wash and thoroughly dry the green beans. Trim the ends – this ensures even cooking and removes any tough parts.
  3. In a food processor, combine basil, garlic, pine nuts, Parmesan cheese, and lemon juice. Pulse until finely chopped. With the processor running, slowly drizzle in olive oil until a smooth pesto forms.
  4. In a large bowl, toss the green beans with the pesto mixture until evenly coated. Spread them in a single layer on the prepared baking sheet.
  5. Roast for 12-15 minutes, or until the green beans are tender-crisp and slightly browned at the edges. For extra crispy beans, you can finish them under the broiler for 1-2 minutes.
  6. Season with additional salt and pepper if needed, and serve immediately while warm.

Notes

Use fresh green beans that snap when bent for best texture. Walnuts work as a budget-friendly alternative to pine nuts. Pesto can be made 3 days ahead and stored in refrigerator. Thaw and dry frozen green beans completely before using.
