How to Blanch Green Beans
This is the move when you want your beans to stay firm rather than limp. It keeps the color sharp and the snap intact, making them ready to eat as is, or perfect for a quick sear in a pan later.
Control the temperature to preserve the snap.
The ice bath is non-negotiable; if you skip it, the residual heat will keep cooking the beans into a soft, olive-drab mess.

- Slotted spoon or spider strainer
- Large mixing bowl

What goes in.
- 1 lbfresh green beans, ends trimmed
- 2 tbspkosher salt (for the water)
- 2 cupsice cubes
Shocking for structure
The sudden transition from boiling water to ice water snaps the skins tight and halts all cooking, ensuring the beans remain bright and crisp.
The method.
Prep the ice bath
Fill a large bowl with cold water and add the ice cubes. Set this near the stove.
Boil the water
Fill your pot with enough water to fully submerge the beans. Bring to a rolling boil and stir in the salt.
Boil the beans
Drop the beans into the water. Set a timer for 3 minutes. The water will return to a boil quickly; keep it there.
Shock the beans
Use the spider strainer to pull the beans out and immediately drop them into the ice bath. Let them sit until they feel completely cool to the touch, about 2 minutes.
Drain and dry
Drain the beans in a colander and pat them dry with a clean kitchen towel so they don't steam in the fridge.
When it doesn't go to plan.
Test one bean at the 3-minute mark; if it's still too raw for your preference, give it 30 more seconds.
Do not crowd the pot. If you have more than a pound, work in two batches so the water temperature doesn't drop too far when you add the beans.
Keep the salt ratio high—it should taste like the sea—to properly season the beans from the inside out.

Can I blanch them ahead of time?
