If you haven’t tried roasting green beans, you are missing out! Something magical happens when vegetables are roasted in the oven, and green beans are no exception. 

This roasted green beans recipe is so simple to make, with fresh green beans and just three pantry ingredients. You’ll toss everything together on a sheet pan and bake in your oven. Then, use all the willpower you have to not eat the whole batch straight from the baking sheet, before it even has a chance to hit your dinner table!

Fresh from the oven, these green beans are soft in the center and crisp on the edges. As the green beans cool they soften, but they still have the same delicious roasted flavor. I like to make a big batch and save any leftover roasted green beans to serve alongside eggs for breakfast.

How to Roast Green Beans

The first step to roasting green beans is to prep your fresh green beans. Wash them under running water and dry them well with a clean kitchen towel. Snap off the stem ends of the green beans using your fingers, or cut them off with a knife or kitchen scissors.

Lay the green beans on a baking sheet lined with parchment paper. The parchment is optional, but it helps to keep the green beans from sticking to the pan and it makes clean up much easier.

Drizzle a little bit of olive oil over the green beans. I find that 1 tablespoon of oil is the perfect amount for 1 pound of string beans, but you can use more or less as desired. Sprinkle on some salt and pepper. I recommend going light on the seasoning before roasting the green beans, because you can always add more later, to taste.

Toss everything together to coat the green beans with the oil and seasonings and then arrange the beans in a single layer on the pan. This will help them to cook evenly and crisp up.

I’ve tested different temperatures for roasting green beans and have found that 400° F is the best for making string beans that are soft in the center yet crisp and charred on the edges. You’ll want to roast fresh green beans for about 20 minutes total, tossing them once halfway through the cook time. Start checking on them at 15 minutes and then continue cooking until the beans are as tender and browned as you like them.

Green Bean Seasoning Ideas

I usually make this basic recipe as is, without any extra seasoning. But you can get creative with the flavors! Here are some ideas to flavor your roasted green beans. Mix and match to make your best green beans recipe!

  • Garlic: Add one or two cloves of minced garlic to the pan during the last 5 minutes of baking time. Sprinkle on a little garlic powder before baking or add garlic butter while hot before serving. 
  • Lemon: Serve the roasted green beans with a squeeze of fresh lemon juice.
  • Parmesan: Toss the hot roasted green beans with grated Parmesan cheese.
  • Fresh Herbs: Sprinkle chopped fresh herbs on right before serving. Try parsley, rosemary, thyme or basil.
  • Dried Herbs/Seasonings: Toss with dried herbs or seasonings before baking. Try basil, Italian seasoning or a mix of chili powder, garlic powder and onion powder (just a little bit goes a long way).
  • Shallots/Onion: Add chopped shallot or onion to the pan to roast along with the green beans.
  • Tomatoes: It might surprise you, but chopped fresh tomatoes are delicious with roasted green beans and onions. You can also roast cherry tomatoes with the green beans – yum!
  • Mushrooms or Potatoes: Roast them with the green beans. Roasted potatoes and green beans are a classic combination. Either cut the potatoes into small (1/2-inch) pieces or give larger potato pieces a ten minute head start in the oven.
  • Bacon: Crumble some oven baked bacon over roasted green beans.
  • Sliced Almonds: A classic way to add flavor and crunch to green beans.

Cooking Tips for Oven Roasted Green Beans

  • Dry the green beans well after washing. If the green beans are wet, they will steam instead of roasting and may get soggy.
  • You only need to trim one end off of green beans – the tough stem end. The end with the thin tip is fine to eat. To trim green beans quickly, line them up so that all of the stem ends are next to each other and cut off the stem ends with one cut with a chef’s knife.
  • Check on your green beans after about 15 minutes in the oven. Then continue cooking them until they are as crisp, tender and browned as you like them.
  • Roasted green beans are best served as soon as you take them out of the oven, but leftovers will keep for 3-4 days in the refrigerator. The best way to reheat green beans is to warm them in the oven, where they will re-crisp a bit.
  • If you make this recipe as written, it is dairy-free, gluten-free, vegetarian and vegan.
  • Add your favorite oven roasted vegetables to the pan for a medley of roasted vegetables.
