1 pound green beans, stem end snapped off
1 tablespoon olive oil
Table salt and ground black pepper
An aluminum foil liner prevents burning in dark nonstick baking sheets. When using baking sheets with a light finish, foil is not required, but we recommend it for easy cleanup.
Adjust oven rack to middle position; heat oven to 450°. Line rimmed baking sheet with aluminum foil; spread beans on baking sheet. Drizzle with oil; using hands, toss to coat evenly. Sprinkle with ½ teaspoon salt, toss to coat, and distribute in an even layer. Roast 10 minutes.
Remove baking sheet from oven. Using tongs, redistribute beans. Continue roasting until beans are dark golden brown in spots and have started to shrivel, 10 to 12 minutes longer.
Adjust seasoning with salt and pepper, transfer to serving bowl and serve.
