3 tablespoons shredded Parmesan cheese, or more to taste
Instructions
Preheat the oven to 400 degrees F (200 degrees C). Coat a baking dish with cooking spray.
Place trimmed green beans into the prepared baking dish. Season with sea salt, pepper, and garlic powder; toss to coat. Sprinkle Parmesan cheese on top.
Roast in the preheated oven until cheese melts and forms a crisp shell over beans, about 10 minutes. Serve immediately.
