Ingredients
Scale
- 1 lb fresh green beans, trimmed
- 2 large yellow onions, thinly sliced
- 3 tbsp olive oil, divided
- Salt and black pepper, to taste
- Optional Additions:
- 1 tbsp balsamic vinegar (for added sweetness and tanginess)
- 2 cloves garlic, minced
- 2 tbsp sliced almonds or toasted pine nuts (for garnish)
Instructions
- Preheat the Oven
Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it with olive oil. - Prepare the Green Beans
Wash and trim the green beans. Pat them completely dry with a clean towel. Toss the green beans in a large bowl with 2 tablespoons of olive oil, salt, and pepper until evenly coated. - Roast the Green Beans
Spread the green beans in a single layer on the prepared baking sheet. Roast for 15–20 minutes, flipping halfway through, until tender with slightly crispy edges. - Caramelize the Onions
Heat 1 tablespoon of olive oil in a large skillet over medium-low heat. Add the sliced onions and a pinch of salt. Cook slowly, stirring occasionally, for 10–15 minutes or until the onions are golden brown and caramelized. For added depth, stir in 1 tablespoon of balsamic vinegar during the last few minutes of cooking. - Combine and Serve
Remove the roasted green beans from the oven and place them in a serving bowl. Gently toss them with the caramelized onions. Taste and adjust seasoning with additional salt or pepper if needed. - Garnish and Enjoy
Sprinkle with optional garnishes like sliced almonds, toasted pine nuts, or freshly grated Parmesan cheese before serving. Serve warm.
Notes
- For extra flavor, add minced garlic to the skillet with the onions during the last 2–3 minutes of cooking.
- To save time, you can roast the green beans and caramelize the onions ahead of time, then reheat them before serving.
- If using frozen green beans, thaw and pat dry before roasting to avoid excess moisture.
