How to Blanch Vegetables
The goal isn't to cook the vegetable through; it is to prepare it for freezing, storage, or finishing in a pan later. You are looking for that split-second transition where the color turns brilliant and the raw bite softens just enough.
The ice bath is non-negotiable.
If you skip the ice bath, the residual heat will continue to cook the vegetables until they are mushy. Prepare your cold water bowl before the pot even hits the stove.
- Large stockpot
- Large mixing bowl
- Slotted spoon or spider strainer
- Colander
What goes in.
- 1 lbfresh vegetables, trimmed and cut into uniform pieces
- 1 gallonwater
- 2 tbspkosher salt
- 2 traysice cubes
Stop the clock
The transition from boiling water to ice water stops the cooking process instantly. Work quickly and keep the ice bath generous so the water remains freezing cold when the hot vegetables hit it.
The method.
Prepare the ice bath
Fill a large bowl with cold water and add enough ice to fill the volume. Set it near the stove.
Boil the water
Bring the water to a aggressive, rolling boil. Add the salt; it should taste like seawater.
Add the vegetables
Drop the vegetables into the water. Do not overcrowd the pot or the temperature will drop too low. Work in batches if needed.
Watch the color
Green vegetables will brighten significantly within 1 to 3 minutes. When they hit that deep, saturated shade, they are ready.
Shock
Immediately remove the vegetables with your slotted spoon and drop them into the ice bath. Stir gently.
Drain
Once fully cooled to the touch, remove from the ice water and spread on a clean towel to dry completely.
Other turns to take.
Hard Vegetables
Carrots, parsnips, or potatoes require 3 to 5 minutes. Test for the tender-crisp threshold by biting into a piece; it should give but retain structure.
Leafy Greens
Spinach or kale only needs 30 seconds. The leaves will wilt instantly and turn a brilliant dark green.
When it doesn't go to plan.
Use a large volume of water relative to the amount of vegetables so the boil returns quickly.
Dry your vegetables thoroughly after the ice bath if you plan on freezing them, or they will form ice crystals.
If your water turns murky or foamy, change it before starting the next batch.

Why do I need to add so much salt?
Salt helps keep the flavor inside the vegetable rather than leaching it out into the boiling water.
Can I blanch without ice?
You can use the coldest running tap water, but it is less effective. You will need to run it over the vegetables for much longer to ensure the center stops cooking.
