Roasted Green Beans

Roasted green beans transform a standard green bean into something amazingly delicious. They get brown and crispy. No more boring canned or steamed green beans here.


If you aren't roasting your green beans, it's a game-changer. These incredibly easy, super flavorful green beans with crispy edges and a touch of caramelization couldn't be more delicious. Thye will make a green bean lover out of anyone. These grilled green beans are also an amazing way to change someone's mind about green beans. 

The best thing about green beans is that they're always in season. Sure, sometimes you might find them looking better than others, but I can always find enough to make a delicious vegetable side dish.

Have you ever had Roasted Green Beans? If not, you're totally missing out! Roasting them brings out their sweetness while keeping them still tender-crisp. Plus, they only take a max of about 15 minutes in the oven! So if you're looking for a fast, delicious veggie side dish, then look no further than these roasted green beans with balsamic, Italian herbs, and a little bit of garlic. Delicious!

Ingredients for roasting green beans including green beans, oil, garlic powder, Italian seasoning, vinegar, salt, and pepper.

How do you make Roasted Green Beans?

Roasting Green Beans really could not be any easier! It only takes about 15 minutes from start to finish.

First, preheat the oven to 425 degrees. Then, toss the trimmed green beans in olive oil, balsamic vinegar, Italian seasoning, garlic powder, salt, and pepper.

Put the green beans on a single layer on a baking sheet. (No need to grease the pan, the olive oil on the green beans should do the trick.)

Roast the green beans for 8-10 minutes, take the pan out to shake/toss the beans around, then put them back in the oven for another 4-6 minutes or until they are lightly browned and cooked through (but still green and tender crisp).

How to choose green beans and prep them for roasting?

When choosing green beans, select the ones that are bright green, crisp, and free from browned or bruised spots. Then store them in the fridge until you are ready to use. 

To prep them, start by rinsing them well to remove any dirt or debris. Then dry them well with a kitchen towel.  They need to be nice and dry so that they crisp up when they are roasted. Then using a knife, just trim the ends. You can also snap them off with your hands, an activity I love having my kids do before meals. If your beans are very long, consider chopping them in half for easier eating.

Should I soak green beans before cooking?

So this is news to me but I just found out some people like to soak their green beans overnight in a bowl of cold water to soak.

I did some research on this and it turns out you don't need to do this at all. It won't improve them, and they aren't dry, to begin with, so there's no need to add extra water like you would do for dried beans.

In fact, soaking the green beans in cold water overnight could lead to mushy green beans as they will be too water-logged and the extra water will steam/bake out onto the pan.

Why do my green beans taste sour?

Oops...did you leave your green beans in the fridge so long that they began to ferment? If they taste sour they are bad...throw them out!

What makes green beans healthy?

In addition to green beans being a great source of fiber (2.7 grams per serving, which means they will keep you feeling fuller, longer), green beans are also great because:

  • They are cholesterol free.
  • The fiber they contain is soluble, which means eating them can help you lower your "bad" cholesterol levels.
  • They can help maintain a healthy blood pressure and keep inflammation to a minimum in your body.
  • They are low in sodium.
  • They contain protein, which is important for strong, healthy bones and muscles.
  • They contain vitamins C, A, K, B, thiamin, and niacin.
  • They also contain folate, iron, magnesium, zinc, calcium, phosphorus, and zinc.

What do I serve with Roasted Green Beans?

While sometimes I've been known to snack on green beans (for real, it's veering on addiction), they're also a wonderful part of a well-rounded meal. Green beans go great as a side with:

  • Grilled or roasted chicken breast with mashed cauliflower or riced cauliflower.
  • Roasted green beans (and all veggies, really) go wonderfully on a bed of lettuce with balsamic dressing.
  • Add smaller cuts of roasted green beans to a pasta or potato salad.
  • Mix smaller pieces of roasted green beans with other beans (lima, chickpeas, navy beans) for an all-bean, protein-packed salad.
  • Serve roasted green beans on the side of a turkey meatloaf or turkey burger.
  • Green beans are also a great side to have with a big piece of meaty fish like salmon, cod, or mahi mahi.

Yum! I put these over white rice. Kids loved the salty flavor. Whatever it takes to have them eat their greens.

They sound great but I would use organic most store bought are full of pesticides, that can't be washed off.

Just my personal preference, but I like my green bean real crispy and I also put sautéed 'spring onions' with them! Oh, so so good!
