A delightful side dish featuring tender green beans and sweet caramelized red onions, perfect for any meal.
Heat the olive oil in a large skillet over medium heat.
Ensure the skillet is evenly coated with oil to prevent sticking.
Add the sliced red onion to the skillet and sauté until softened and starting to caramelize.
Stir frequently to avoid burning and achieve even caramelization.
Add the green beans to the skillet and season with salt and pepper.
Toss the beans well to coat them evenly with the seasoning.
Cover the skillet and cook until the green beans are tender-crisp, about 8 minutes.
Check occasionally to ensure the beans are not overcooked.
Uncover and continue cooking, stirring frequently, until the onions are fully caramelized and the beans are tender, about 5 more minutes.
Let the onions brown slightly for a richer flavor.
Drizzle balsamic vinegar over the vegetables, stir to combine, and serve warm.
The vinegar adds a tangy finish that balances the sweetness of the onions.
