Preheat your oven to 200°C (400°F) and line a baking sheet with parchment paper or lightly grease it with olive oil.
Wash the green beans thoroughly under cold water, then trim the ends and pat them dry with a clean kitchen towel.
Peel the yellow onion, cut it in half, and slice it thinly into half-moons.
Peel the garlic cloves and mince them finely or slice them thinly, depending on your preference.
Place the green beans, sliced onion, and minced garlic in a large mixing bowl.
Drizzle the olive oil over the vegetables, then sprinkle the salt, black pepper, and optional red pepper flakes evenly over them.
Toss everything together until the green beans and onions are thoroughly coated in the oil and seasonings.
Spread the mixture evenly on the prepared baking sheet, ensuring the vegetables are in a single layer for even roasting.
Roast in the preheated oven for 15-20 minutes, stirring halfway through, until the green beans are tender and slightly charred, and the onions are caramelized.
Remove the baking sheet from the oven and transfer the roasted green beans and onions to a serving dish. Serve warm as a side dish to complement your main course.
