Preheat the oven to 400°F. Rinse the green beans and pat dry. Place them on a large baking sheet and drizzle with olive oil. Sprinkle liberally with salt and pepper and toss to coat.
Spread the green beans across the baking sheet and roast for about 12-15 minutes. They are ready to eat when they are bright green and crisp tender.
Notes
If you like your green beans extra crispy (like we do) add an additional 10 minutes to the cooking time!
