All you have to do is trim the green beans, toss them with the oil and seasonings, and bake to perfection.

How to Season Oven Baked Green Beans
You don’t need many ingredients to help these green beans cooked in the oven shine. The base recipe uses just 5 ingredients (including the oil and salt & pepper), and the oven caramelization does the rest.
- Green beans: Use green beans (aka string beans/snap beans) that are firm and free from wrinkles. Fresh or frozen green beans work for this baked green beans recipe method.
You could also use Haricot verts for this method, reducing the roasting time by a few minutes.
- Olive oil: Or another neutral cooking oil. For a richer flavor, use a combination of oil and melted butter.
- Salt & Black pepper: Season to taste. I recommend using sea salt or kosher salt.
- Lemon: I recommend using fresh lemon (organic and unwaxed is best, especially if you plan to add some lemon zest for extra flavor to the roasted green beans).
What Spices Go Well with Green Beans
The truth is that oven-baked green beans are incredibly versatile. There are plenty of ways to add flavor to your green beans with extra herbs, spices, veggies, and other ingredients like cheese. Check out my sautéed green beans recipe for all my top recommendations.
In terms of spices and herbs, my favorite options to roast fresh green beans in the oven include:
- Red pepper flakes
- Smoked paprika
- Onion powder
- Garlic powder (or fresh sliced garlic or minced garlic, but I recommend powder)
- Cajun seasoning
- Italian seasoning
- Curry powder
- Taco seasoning
Regarding fresh herbs, parsley and basil pair particularly well with oven-roasted green beans. Mint, chives, and green onion would also work.
What Else Could I Add to the Roasted Green Beans Recipe?
Add a drizzle of balsamic vinegar over the green beans for an extra tangy flavor. Grated parmesan cheese (or nutritional yeast for a vegan option) sprinkled over the roasted green beans a couple of minutes before they’re ready is also a winner.
For super crispy roasted beans, sprinkle over some breadcrumbs or panko breadcrumbs before roasting the green beans.
Depending on where and when you plan to serve the roasted string beans, you might also want to mix in lightly toasted slivered almonds or pecans and dried cranberries (making for a simple and delicious Thanksgiving side dish).
How to Roast Green Beans
Preparing and roasting green beans in oven requires minimal effort for maximum flavor; you’ll love them.
How to Prepare Fresh Green Beans
First, rinse the beans in a colander and pat them dry. Make sure they are completely dry.
To trim green beans, grab a handful of the beans and place them on a cutting board with the stem ends lined up. Using a long, sharp knife, slice off the ends of the beans, then flip them over and repeat. Do this with all the beans.
If any of the beans have tough strings running down the seam of the pod, remove them now, too.
How Long to Roast Green Beans
Preheat the oven to 400ºF/200ºC (or to 400ºF/200ºC fan-assisted). I do this while preparing the beans.
Transfer the prepared green beans to a large baking sheet in a single layer. Drizzle with the oil, salt, and pepper. Toss well to coat.
Roast the green beans for 12-15 minutes, flipping/tossing them halfway.
Taste and adjust the seasonings of the sauteed green beans, then serve them optionally with a drizzle of lemon juice!
For more citrus flavor, zest the lemon first and add about a teaspoon of the zest to the green beans in the oven.
Can You Roast Frozen Green Beans
Roasted frozen green beans are super simple to prepare and require no thawing.
Simply preheat the oven. Then toss the frozen green beans with the oil and seasonings just before spreading them across the baking tray.
If your green beans have lots of excess ice, I recommend rinsing off the excess and patting them dry.
Roast the frozen green beans for between 25-30 minutes at 450ºF/230ºC, flipping them halfway.
These crispy oven roasted green beans are a proudly versatile side dish you can pair with almost any meal. For tons of inspiration, check out my sautéed green beans recipe. Also, here are a few dishes you could pair with the baked green beans:
- Chicken, steak, and meatloaf

Can You Roast Frozen Green Beans?
- Simply preheat the oven. Then toss the frozen green beans with the oil and seasonings just before spreading them across the baking tray.If your green beans have lots of excess ice, I recommend rinsing off the excess and patting them dry.
- Roast the frozen green beans for 25-30 minutes at 450ºF/230ºC, flipping them halfway.
- Make ahead: You can rinse, dry, and de-string the green beans 2-3 days in advance. Store them in an airtight container in the fridge until you're ready to roast the green beans. Store: Store any leftover oven-roasted green beans in an airtight container for 3-4 days in the refrigerator, making them great for meal prep.Freeze: If you want to freeze the baked green beans, they will become very soft upon thawing. However, they are fine to freeze in an airtight container/Ziplock bag for up to 4 months. Freeze them within an hour of roasting them for the best results.Reheat: I prefer to reheat the roasted green beans in a skillet with a small amount of oil or butter. You could also reheat them in the oven at 400ºF/200ºC for 15-18 minutes until warm. Avoid a microwave unless you don't mind soft beans.
- To save time: You can purchase the green beans already trimmed.
- Trim the beans: If you have whole green beans, trim them and remove any tough strings, as they’re tough and fibrous.
- Ensure the beans are dry: Any water droplets can lead to soggy roasted green beans.
- Adjust the cooking time: Based on how tender you want the oven green beans to be on the inside and depending on the size of the beans. For example, thinner beans like Haricot Verts will require less time.
- Don’t crowd the baking green beans: Air flow will help them to crisp up rather than just steam and stay limp. Spread them in a single layer with some space between them.
