I’m pretty picky when it comes to green beans. I don’t love them unless they’re prepared right! One of my favorite ways to make them tasty is to roast them so they get a little charred on the edges. Topping them with caramelized onions takes them over the top! Green beans are also very healthy. They’re full of vitamins A, C, and K, calcium, and potassium. Plus, they’re low in calories, fat, and carbs and high in fiber.

What is the difference between caramelized onions and sauteed onions?

To sauté onions, you cook them for a few minutes until they’re softened and browned. Caramelized onions are cooked lower and slower, at least 30 minutes to an hour depending on how many you’re making, which allows the natural sugar in onions to caramelize. The result is sweeter onions with a more complex flavor.

How to Caramelize Onions

Although caramelizing onions takes time, it’s not hard at all. You can use any onions that you want, but I really like Vidalia onions for caramelizing. You can also caramelize using butter instead of olive oil if you prefer.

Cook sliced onions, seasoned with salt and pepper, in olive oil on medium-high heat in a large nonstick skillet.
Stir the onions often until they start to brown, which should take about 10 minutes.
Reduce the heat to medium-low and cook for about 30 minutes until the onions are a deep golden brown.

What to Serve with Roasted Green Beans

These roasted green beans make the perfect side dish for really any protein. They’d be delicious with a whole roasted chicken, roast beef, or a stuffed turkey breast. Serve the green beans with mashed potatoes, smashed sweet potatoes, or baked sweet potato to round out the meal.
