Forget soggy frozen green beans. With my foolproof technique, you’ll have perfectly caramelized and flavor packed roasted green beans every time without having to buy them fresh. No one will even know you started from frozen.
Try these simple Roasted Frozen Green Beans on a busy weeknight!
Growing up in the South, green beans have always been a staple side dish. Needless to say, I’ve made a lot of green beans in my life. Making them for over 30 years has taught me the difference in roasting time needed between soggy and caramelized.
With my foolproof method, you’ll turn a simple bag of frozen green beans into a side dish your family will request over and over, even the picky eaters!
You have to trust me on this one; the key is in the roasting time. It’s well worth the wait! It’s going to mean the difference between a soggy pan of green beans and a caramelized delicious one. When they’re done, you’ll have the perfect balance of busy life shortcut and a homecooked side.
Green beans basically go with anything, but I love serving them up with French Onion Meatballs or Honey Garlic Chicken. They’re such an easy side dish for weeknight dinners.
String beans vs. Green beans
Green beans and string beans are actually the same things! So if you see frozen string beans, you are safe to buy that kind.
The name string bean is actually somewhat outdated. It refers to the thin, fibrous “string” that used to run down the length of the pod and that had to be removed by hand, bean by bean, like snap peas. Also known as snap beans.
But in the 19th century, these strings were eliminated thanks to careful breeding, according to Serious Eats. These days, only heirloom varieties contain strings.
You may also see thin green beans (also called haricots verts) which are a French style of green beans. These work great as well!

Frozen Green Beans Recipe Ingredients
Frozen green beans seem like they’d be enough on their own, but they’re actually even better with some light seasonings. Here’s what you’ll need to grab from your pantry to make these
- frozen green beans – You can use any frozen green bean for this, including the steamable kind. However the steamable bags come in special packaging and may cost more, so keep an eye out.
- avocado oil – You can use sesame oil, olive oil, or vegetable oil instead. I like avocado oil because it has a neutral taste. You can even melt butter in place of the oil. Just use the melted butter the same way as the oil.
- coarse kosher salt – You can use coarse sea salt instead. Stay away from table salt though — it is much better for seasoning a finished dish than for cooking.
- ground black pepper – I like to use this pepper grinder for cooking. Fresh pepper makes a huge difference in flavor.
- garlic powder & onion powder – make sure they aren’t expired for the best taste. Most spices need to be replaced after 6 months.
If you prefer, you can use a seasoning salt like Lawry’s or Krazy Jane’s instead of the salt, pepper, garlic, and onion powders. Italian seasoning will give it great flavor as well.

Frozen Green Bean Recipe tips and tricks
Green beans deserve salt, pepper, and seasonings to help bring out their bright flavor. Don’t under season them. The seasoning for frozen green beans in this recipe is simple and easy to make with items you probably already have on your spice rack.
Green beans can easily be undercooked. You want them to have time to roast out the extra water that is captured when they are frozen.
If you want to check for doneness, use a pair of tongs to fish out a green bean from the pan. Let it cool slightly, then take a bite. It should be mostly soft with a slight crispiness. If it is crunchy, it needs more time.
Should I thaw Frozen Green Beans before cooking?
Thawing frozen green beans seem like it would make sense, but it’s actually better to cook them from frozen. Cooking thawed beans can result in mushy green beans, which is no good!
How to make this tasty side dish work for the whole family
If you have a picky eater, the seasoning and texture will be the biggest factors. Using seasoning you know they like is a great option.
In regards to texture, instead of leaving them tender-crisp texture, continue to roast them until they are softened.
Storing leftover Roasted Frozen Green Beans
Allow the green beans to cool completely. Place them in an airtight container in the fridge for up to 5 days.
What to serve with this Roasted Frozen Green Beans Recipe
Green beans make a wonderful side dish for so many recipes.
One of my favorites is as a green veggie to go with any kind of meat and potatoes. Whether it’s steak and baked potatoes, crispy fried pork chops, or lemon chicken and mashed potatoes.
Try them with an Asian dish like orange chicken or beef teriyaki.
Green beans also work well with fish dishes. This baked lemon butter salmon can be cooked in foil in the oven alongside your veggies.
Reheating Frozen Green Beans in Oven
Once you have made this recipe, they are best reheated on the stovetop. I recommend using a large skillet.
You may use a drop of oil if your pan is dry, but the beans should have retained the seasoning and should be moist enough on their own.
Cook the beans over medium heat, pushing the beans around with a silicone spatula, until heated through, about 5 minutes.
An alternative method would be to use your air fryer. Place the beans in the air fryer basket and heat at 350°F until heated through.
Toppings to add to Roasted Frozen Green Beans
While frozen roasted green beans are a perfect side dish on their own, next time try adding some toppings. Some great ones include:
- almond slivers
- balsamic vinegar
- pat of butter
- fresh parsley
- feta cheese
- red pepper flakes
- parmesan cheese
- lemon juice
Frozen Green Beans FAQs

Sure! This recipe works well with fresh beans too! But since they’re not frozen, you will need to cut back on the cooking time a little bit. They will take around 20 minutes at 350°F.
