What You’ll Need:
2 lbs. fresh green beans, rinsed well, stem ends trimmed
1 small head garlic
1/4 cup plus 2 T extra-virgin olive oil
1-1/2 Tablespoons finely grated lemon zest (from 1 to 2 medium lemons), plus 2 T fresh lemon juice
Kosher salt and freshly cracked black pepper
1/3 cup (about 1-1/2 oz.) pine nuts (or you can buy roasted pine nuts)
1/4 cup coarsely grated Parmigiano-Reggiano
1 Tablespoon coarsely chopped fresh flat-leaf parsley
What to Do:
Position oven racks in the top and bottom thirds of the oven. Heat the oven to 450°F.
Put the beans in a large bowl. Peel the garlic, quarter each clove lengthwise (if the cloves are small, halve them), and add them to the green beans. Toss the beans and garlic with 1/4 cup of the olive oil, 1 Tablespoon of the lemon zest, 1 teaspoon salt and 1/2 teaspoon pepper.
Spread the beans on a rimmed baking sheet and roast in the top third of the oven for 10 minutes. Stir the beans and garlic with a spatula for more even cooking and coloring. Continue roasting until the beans and garlic pieces are lightly browned and tender throughout, or another 10 to 15 minutes.
Meanwhile, spread the pine nuts out on a rimmed baking sheet and toast in the bottom third of the oven until just golden, or about 5 minutes.
Transfer the beans to a small serving platter or shallow bowl and dress with the lemon juice and the remaining 2 Tablespoons olive oil. Toss gently to coat and season to taste with salt and pepper. Sprinkle on the toasted pine nuts, the remaining ½ Tablespoon lemon zest and the Parmigiano. Enjoy!
