- green beans, trimmed - olive oil - kosher salt + fresh pepper to taste - garlic powder - grated Parmesan
Preheat the oven to 425°F and grease a baking sheet.
Lay green beans out on the baking sheet and drizzle oil over them.
Season with salt, pepper, garlic powder and the Parmesan cheese and toss to evenly coat.
Spread them out on the sheet so that they all lay flat and place on the lower third section of your oven.
