How to Freeze Green Beans and Retain Their Freshness

Updated: May 07, 2024

Learn how to freeze green beans so you can preserve that bumper crop from your garden (or the farmers market). Plus, we'll go over the best way to thaw them so they stay crisp.

On our little homestead in Northern Vermont, we try to grow all of the vegetables that we’ll need for an entire year. The garden is beautiful, but it’s sometimes overwhelming—I’m a notorious over-planter; it’s normal to have 120 tomato plants, right? And tomato plants aren’t the only thing we have a plethora of. We have pounds and pounds of beautiful green, yellow and purple beans ripening all at the same time!

Let’s talk about how to freeze green beans so none of our bounty goes to waste. I love making garlicky and spicy pickled recipes, but there are only so many vinegar-soaked beans one can eat. Freezing green beans is a great way to ensure that they last, and you can use them in so many green bean recipes when you’re ready to thaw them.

How to Choose Green Beans for Freezing

Whenever you plan to freeze fruits and vegetables, it’s important to choose produce of very high quality. For this task, you’ll want to select beans that are smooth, brightly colored, blemish-free and not too large. If you can see the bean seeds swelling inside of the pod, it means the beans are starting to mature and won’t be as tender as they were when they were young.

Uniformity can be helpful too. I wouldn’t spend too much time sorting beans by size, but if you roughly divide the bigger and smaller beans into piles and start cooking the larger ones first, you’ll end up with a more consistent product.

The process of freezing beans is simple. Rinse the beans, and decide if you’d rather leave them whole or cut off their tops and tails and chop them into uniform pieces. This all depends on how you’d like to use your beans later. I generally leave mine whole. If you do see any blemishes on the beans, remove them before processing.

Bring a large pot of salted water to a boil. Salting the water until it tastes briny will make the beans taste delicious, and some say it also helps to prevent vitamins and minerals from leaching from the beans into the blanching water.

While you’re waiting for the water to boil, place a colander in the sink, and prepare a nice big ice bath in a mixing bowl. You’ll use this to shock the beans in cold water as soon as they’re done cooking.

When the water boils, add the larger beans, followed about 30 seconds later by the smaller beans. Cook until the beans are exceptionally bright green (or bright yellow, if they’re wax beans), pour the beans into the colander, shake to remove some of the hot water, and immediately plunge them into the ice bath.

When the beans are cool, spread them out on kitchen towels or paper towels until they are dry, and then freeze them on baking sheets in single layers. Once they are frozen, the beans can be moved into freezer-safe resealable plastic bags or vacuum sealed for longer-term storage.

Tips for Freezing Green Beans

  • Skip the blanching: In a hurry? You can freeze washed and dried raw green beans, but they may have a shorter shelf life. Why? Because blanching denatures enzymes that cause produce to break down. If you do freeze raw beans, make sure to cook them once thawed since you can’t eat raw green beans.
  • Try sauteing: You can also freeze lightly sauteed beans. However, these beans won’t be cooked as uniformly as blanched beans, so they may not have an ideal texture when they defrost.
  • Keep track of dates: Label your beans (and anything else in your freezer) so that you know when you froze them, and whether or not they were cooked before freezing.
  • Vacuum seal the beans: This step requires another tool and makes the preservation process take longer, but it’s a great way to avoid unsightly freezer burn and extend the life of your produce even further.

How to Thaw Green Beans

Some recipes will specifically call for green beans that are thawed, but most of the time, you can use frozen green beans to use up your stash.

If you do need to thaw your green beans, you can safely do so by pouring the beans into a colander and rinsing them in cold water until they are no longer frozen. Another option is to place the freezer bag in the fridge the day before you want to use the vegetables. When you’re in a hurry, gently defrost them in the microwave.

If the beans will be served as a side dish, I like to toss them with oil while still frozen, and roast them in a 425°F oven or saute them in a very hot pan until they take on a little bit of color. The beans should still be bright green, but with patches of dark charred bits.

You can also add frozen beans directly to soups like slow-cooker minestrone and stews like this satisfying beef stew, or use them in cozy Thanksgiving green bean casseroles—you don’t have to wait for the holidays to enjoy them!

When should you not use frozen green beans? When a recipe explicitly calls for the beans to be fresh.
