Why you’ll love this recipe

Steamed fresh green beans make a delicious and healthy side dish. I especially love it when they are in season and can be found at my local farmers’ market. Cheap, fresh, and you know your money is going to support local producers!

Microwaving raw green beans is easy, you just need to take a little care to ensure that they retain their flavor and texture (no one wants over-cooked green beans!).

The easy way to do this is to steam them in the microwave rather than attempting to boil them. Steaming vegetables helps to retain their texture, along with nutrients, both of which can be lost if they are cooked directly in boiling water.

What do you need?

To cook fresh green beans in your microwave you will need a microwave-safe dish with a close-fitting lid. You could also use a microwave-safe bowl with a plate on top, but make sure it fits well enough to prevent the steam from escaping during cooking.

If you don’t have a dish with a lid, you can cover it with plastic wrap, just remember to pierce it a few times with a sharp knife.

You may find the beans in the bottom of the bowl that are sitting in the water get a little overcooked. They will still taste delicious, but may be a little soft and look a little wilted.

You can avoid this by using a microwave-safe trivet to raise the beans up out of the water before cooking. I have this Joie silicone vegetable steamer*, which works perfectly.


All varieties of fresh green beans can be microwave steamed using the method below. You can also use frozen green beans, though the cook times will be a little longer.

Green beans, string beans snap beans, wax beans, and haricot vert just need a wash, trim the ends, and I usually cut them in half so the pieces are a couple of inches long.

For Romano beans, Italian green beans, flat beans or runner beans (different names, same bean), give them a wash, trim the ends, and then cut them into pieces around 1-2 inches long.

You also need a small amount of water in the bottom of the bowl. The right amount will boil quickly and fill the bowl with enough steam to cook the beans. I usually find around an inch of depth works – this is around 1 cup in the bowl that I use.

How to steam fresh green beans in the microwave

Place the steamer basket (if using) into the microwave safe dish, add the water and trimmed green beans, and cover the container (ensure the lid has holes to let the steam escape).

You will need to microwave the bowl of beans until the water is boiling and the bowl has filled with steam. It needs to boil continuously for around 3 minutes, and then should be left for at least 1 minute with the lid on to allow the beans to finish cooking in the steam.

How long to microwave green beans

The total length of time you will need to microwave the beans for depends on the power of your microwave. The times in the recipe below are perfect for my 1000W microwave, so if you have a lower wattage you may need to increase the times a little.

You can estimate cooking times for a different wattage microwave using the chart below:
