The difference between a crisp, creamy coleslaw and a sad, watery one is not the dressing, it is what you do to the cabbage first. Gordon Ramsay's version keeps it classic, green and purple cabbage, carrot, a light mayo-and-vinegar dressing, and celery seed, but one extra step keeps it crunchy for hours instead of weeping into a puddle.
The recipe card below has the full method. This guide explains why slaw goes watery, the salt-and-drain fix, and how to balance the dressing so it coats without drowning.
Why Coleslaw Turns Watery

Cabbage is about 92% water, and that water is the enemy of a good slaw. Salt draws it out by osmosis: salt outside the cells pulls water out through the cell walls to balance the concentration. So the moment you dress a bowl of raw shredded cabbage with a salty, creamy dressing, the cabbage starts leaking water, which thins the dressing and leaves the slaw sitting in liquid within an hour.
Cabbage is a genuinely nutritious, water-rich vegetable, which is exactly why the water has to go somewhere. Once you understand it is osmosis, the fix is obvious: pull the water out on purpose, before you dress it. Coleslaw itself takes its name from the Dutch koolsla, meaning cabbage salad, brought to America by Dutch settlers.
The Salt-and-Drain Fix

Toss the shredded cabbage with a teaspoon of salt and let it sit in a colander for 20 to 30 minutes. It will release a surprising amount of water. Rinse briefly, then squeeze it dry in a clean towel or press it in the colander. Now dress it: because the cabbage has already given up its water and stays crisp-tender, the dressing coats it instead of being diluted, and the slaw holds its crunch for hours, even overnight. Skip this step and you are back to watery slaw and reaching for a spoon to drain the bowl.
For the dressing, whisk the mayonnaise with both vinegars, the sugar, celery seed, and pepper before it meets the cabbage, and taste it: it should be brighter and sharper than you expect, because the cabbage mellows it. Shred everything fine and even so every strand gets coated.
Make It Your Own
The base takes well to a twist. For an Asian-style slaw, swap the white vinegar for rice vinegar and add a little toasted sesame oil, a splash of soy, and some sliced scallion; finish with sesame seeds. For a sharper, lighter slaw, lean up the vinegar and cut the mayo with a spoon of Dijon or a little yogurt. A grated apple or a handful of raisins tips it sweet.
What to Serve It With
Coleslaw is the classic cool, crunchy foil for anything rich or smoky: pile it next to buttermilk fried chicken, pulled pork, or a lamb burger, or pop it right on the sandwich. It is a natural picnic and barbecue side that travels well and feeds a crowd. Browse the full recipes collection for more sides and mains.

Notes
Coleslaw FAQs
The questions that come up most: why coleslaw turns watery, how to keep it crunchy, how far ahead you can make it, and how to balance the dressing.
Why does my coleslaw get watery?
Cabbage is about 92% water, and the salt in the dressing pulls that water out by osmosis. Dress raw cabbage and it weeps within an hour. The fix is to salt the shredded cabbage first, let it drain, and squeeze it dry before dressing.
How do you keep coleslaw crunchy?
Salt the shredded cabbage, let it sit 20 to 30 minutes, rinse and squeeze it dry, then dress it. Removing the water first means the cabbage stays crisp and the dressing is not diluted, so the slaw holds its crunch for hours.
Can you make coleslaw ahead of time?
Yes, especially if you salt-and-drain the cabbage first, which keeps it from going watery. Dressed slaw keeps a day or two refrigerated; if it releases any liquid, drain and toss it before serving.
What is the best cabbage for coleslaw?
A mix of green and purple cabbage gives the best texture and color, with carrot for sweetness. Green cabbage is the crisp base; purple adds crunch and a striking look.
How long does coleslaw last in the fridge?
About 3 to 5 days in an airtight container. It is best in the first day or two; after that the cabbage softens even if you drained it well.
How do you balance coleslaw dressing?
Make the dressing brighter and sharper than you think you want, since the cabbage mellows it. Whisk mayo with vinegar, a little sugar, and celery seed, then taste and adjust before tossing.
