Preheat your oven to 400°F (200°C).

Rinse the fresh green beans thoroughly under cold water. Trim the ends and pat them dry.

In a large mixing bowl, toss the dried green beans with olive oil, minced garlic, salt, and black pepper.

Spread the coated green beans in a single layer on a baking sheet lined with parchment paper.

Roast the green beans for about 15 to 20 minutes, checking halfway through.

Sprinkle a generous amount of grated Parmesan cheese over the hot green beans and return to the oven for 2 to 3 minutes.

Serve immediately while hot.
