Oven roasted green beans are a simple and delicious side dish that goes with just about any meal. I love serving these green beans alongside a chicken parmesan with some egg noodles, or a delicious pork tenderloin. They’re a fun and versatile side! 

Roasted green beans take about 25 minutes from start to finish, and they are SO easy to prepare while your main dish cooks. I like to prepare them early and get them onto the baking sheet in the fridge. Just pop them in the oven 20 minutes before dinner is ready to serve!

No matter how you like your green beans, they are always a fun side dish. Green Beans with BaconBacon Wrapped Green Bean Bundles, you name it (and of course we can’t forget a classic Green Bean Casserole)!

This simple roasted green bean side dish is an easy way to enjoy them too! In the summer, I love growing fresh green beans in my garden next to my tomatoes and other fresh veggies. They are even great as a snack with some ranch dip!

How To Trim Green Beans

Green beans have 2 sides to them, one tip is edible and tastes the same as the rest of the bean. The other side has a rough knob where the green bean grew from the plant.

To trim green beans:

  • As you wash them, use a pair of kitchen scissors to cut the hard end off of the bean.
  • Alternatively, line them up on a cutting board so all of the hard ends are on the same side, and slice them using a sharp knife.

How To Make Roasted Green Beans

These roasted beans could not be easier to make.

  1. Prep the beans. Wash them in cold water, trim them, and dry them.
  2. Place the beans on a baking tray and drizzle with olive oil
  3. Add seasoned salt, pepper, and garlic powder (and any other seasonings you’d like). Toss to combine.
  4. Roast beans until tender-crisp. I like to broil them for an extra minute before pulling them out.

How Long To Roast Green Beans: Green beans take 18-22 minutes at 400°F depending on how well you like them done. If you have another dish in the oven at a different temperature, you can adjust the cooking time for the roasted green beans. I usually cook my casseroles at 350°F, so if I am making roasted beans as a side dish, I usually add about 5 minutes to the cook time. They’re super forgiving!

  1. I have been doing green beans like that for years and years. How about something different?Thank You.4 stars

    1. Well Kate, lucky for you! Most of us had never had them this way, and it’s way more delicious than how the rest of us were taught to cook them.

      Thankfully Holly was very gracious and gave you other ways. If it were my blog, I would have been very tempted to say something else. XD5 stars

      1. Christina, I love your reply to Kate! Kate, if you can’t say something nice about a recipe, keep quiet!!!5 stars

      2. Christina, I like the way you think. Your comment to Kate was well written, gentle & kind. I wish we were neighbors!
        Holly, I’ve roasted a lot of veggies but I’ve yet to roast green beans. In the next couple days I’ll definitely give this recipe a go at it. God bless you Holly for all u do 5 stars
