Follow these simple steps to create your own delicious Roasted Green Beans with Garlic Parmesan:

1. Preheat the Oven: Preheat your oven to 425°F (220°C).
2. Prepare Green Beans: Rinse the fresh green beans under cool water and trim the ends.
3. Mix Ingredients: In a large mixing bowl, combine the green beans, olive oil, minced garlic, salt, black pepper, and red pepper flakes (if using). Toss to coat the green beans evenly.
4. Spread on Baking Sheet: Line a baking sheet with parchment paper for easy cleanup. Spread the seasoned green beans in a single layer on the sheet.
5. Roast in Oven: Place the baking sheet in the preheated oven and roast for 15-20 minutes. The green beans should become tender and slightly browned.
6. Add Parmesan: Remove the baking sheet from the oven, and immediately sprinkle the grated Parmesan cheese over the hot green beans. Toss gently to distribute the cheese.
7. Return to Oven: For an extra golden touch, return the green beans to the oven for an additional 2-3 minutes or until the cheese melts slightly.
8. Finish with Lemon Juice: Optional – Drizzle with lemon juice before serving for a burst of freshness.
9. Serve Immediately: Transfer the green beans to a serving dish and enjoy!
