You're standing in the produce aisle staring at a mountain of green cabbage. It’s intimidating. You’ve got a family reunion, a backyard wedding, or maybe just a massive neighborhood BBQ on the calendar, and now you’re the "slaw person." The pressure is real because nobody wants to be the host who runs out of sides twenty minutes into the buffet. But let’s be honest: nobody wants ten pounds of soggy, leftover cabbage sitting in their fridge for a week either. Figuring out how much slaw for 50 people is actually a bit of a science, mixed with a healthy dose of common sense about who is actually showing up to eat.
Standard catering math usually tells you to plan for about four ounces per person. That sounds simple. It isn't.
If you just multiply 50 by 4, you get 200 ounces, which is 12.5 pounds. But wait. Is that 12.5 pounds of shredded cabbage? Or 12.5 pounds of finished, dressed salad? There's a massive difference. Cabbage is mostly water and air. Once you hit it with salt and vinegar—or a heavy mayo dressing—it wilts. It shrinks. It becomes a completely different beast. If you buy 12 pounds of cabbage, you’re going to have enough slaw to feed an army, mostly because you haven't accounted for the weight of the dressing or the "shrink factor."
The Raw Truth About Cabbage Math
Most professional kitchen managers, like those following the guidelines from the USDA Food Buying Guide for Child Nutrition Programs (which is secretly the best resource for bulk cooking), suggest that one pound of raw, untrimmed cabbage yields about 10 to 12 servings of coleslaw.
Let's break that down.
If you are serving a crowd of 50, and you want everyone to have a decent-sized scoop, you’re looking at roughly 9 to 10 pounds of prepared coleslaw. To get there, you don't need 10 pounds of cabbage. You probably need about 6 to 7 pounds of shredded cabbage and about 3 to 4 pounds of dressing and "add-ins" like carrots or onions.
Think about the plate. Is the slaw a topper for a pulled pork sandwich? If so, your needs plummet. You might only need two ounces per person. Is it a standalone side dish at a fish fry? Now we're talking five or even six ounces for the enthusiasts.

Context is everything.
Honestly, the biggest mistake people make is buying those pre-shredded bags without checking the weight. A standard bag of coleslaw mix at a grocery store like Kroger or Publix is usually 14 to 16 ounces. To hit your target for 50 people, you’re looking at buying at least 8 or 9 of those bags. It feels like a lot when it’s in the cart. It looks like even more when you dump it into a giant bowl. But remember: the wilt is coming.
Why The "Shrink Factor" Changes Everything
Cabbage is structurally unique. It’s crunchy because of the cell walls. When you add a dressing—especially one with a high salt or sugar content—osmosis kicks in. The dressing draws the water out of the cabbage. This is why the bottom of the bowl is always a watery mess by the end of the party.
If you make your slaw the night before, it will be half the volume it was when you mixed it. It will also be significantly heavier because it's sitting in its own released juices.
Texture vs. Volume
- Freshly Mixed (0-2 hours): High volume, very crunchy, dressing sits on top.
- Set Slaw (4-12 hours): Medium volume, better flavor integration, "slumped" appearance.
- Overnight Slaw (24+ hours): Low volume, very soft, potentially "soupy."
If you’re aiming for that classic KFC-style texture, you actually want some of that shrinkage. But you have to account for it in your head. When calculating how much slaw for 50 people, I always lean toward a slightly "drier" initial mix if I’m prepping in advance. You can always add a splash of cream or extra mayo right before serving to loosen it back up.
The Secret Variables: Who Is Eating?
I once saw a guy eat a pint of coleslaw by himself at a church basement dinner. Just one guy. While that’s an outlier, you have to look at your demographic.
Teenagers? They might ignore the green stuff entirely in favor of more chips.
Older crowds? They tend to appreciate a well-made, traditional side dish.
The "Sandwich Factor" is the real kicker though. If you are serving sliders or BBQ, people are going to put the slaw on the meat. This is a game changer. It cuts consumption by nearly 40%. You can safely drop down to about 6 pounds of total product for 50 people if it’s primarily a condiment rather than a side.
Don't forget the color. Red cabbage is denser and heavier than green cabbage. If you’re doing a 50/50 split for aesthetic reasons, you’ll find the red cabbage bleeds color into the mayo, turning everything a weird shade of Barbie pink. It also weighs more per cup. Keep your ratios in check: 70% green, 20% red, 10% shredded carrots. That’s the sweet spot for visual appeal without turning the bowl into a heavy, purple mess.
Pro Tips From The Catering Trenches
Let's talk logistics. You have 50 people coming in two hours. You realize you didn't buy enough dressing.
The "Golden Ratio" for slaw dressing is generally one part dressing to three parts cabbage by weight. If you have 6 pounds of cabbage, you need 2 pounds (about a quart) of dressing. If you’re using store-bought jars of Marzetti or Hellmann's, check the fluid ounces. A standard 16oz jar is actually about a pound. So, two jars for 50 people is usually your baseline.
But please, for the love of all that is holy, don't just dump the jars in.
Real experts know that a "dry" slaw is a better slaw. Start with half the dressing. Toss it. Let it sit for 20 minutes. Look at the bottom of the bowl. If there’s already liquid pooling, stop. If it looks bone dry, add more. The cabbage will continue to release moisture as it sits on the buffet line, especially if it’s a warm day.
Avoiding The Sogginess Disaster
- Salt and Drain: If you have the time, salt your shredded cabbage in a colander for 30 minutes. Rinse it with cold water and pat it dry. This removes the excess water before you add the dressing.
- The Mayo Barrier: If you’re worried about it getting watery, toss the cabbage in a tiny bit of oil first. It creates a slight hydrophobic barrier that keeps the vinegar in the dressing from penetrating the cabbage cells too quickly.
- Temperature Control: Keep the bowl on ice. Warm slaw isn't just a food safety nightmare; it also loses its structural integrity faster.
Beyond The Mayo: Vinegar Slaw Adjustments
Everything changes if you’re doing a Carolina-style vinegar slaw. Without the fat of the mayo to "bulk" it up, vinegar slaws feel lighter. People eat more of them because they aren't as heavy on the stomach. If you’re going the vinegar route, increase your cabbage estimate by about 15%.
Vinegar slaws also last longer on the table without becoming a biohazard. This is why they are the king of outdoor summer graduations. If the temp is over 80 degrees, skip the mayo. Your 50 guests will thank you for not giving them food poisoning, and the slaw will stay crispier longer.
Buying Guide For 50 Servings
If you are at the store right now, here is exactly what you should put in the cart. No fluff.
You need three large heads of green cabbage. Each head usually weighs around 2.5 to 3 pounds. Once you core them and remove the outer leaves, you’ll be left with about 2 pounds of usable cabbage per head. That’s 6 pounds total.
Add two large carrots. Shred them yourself. The pre-shredded carrots in the bag are often woody and tasteless.
Buy one medium red onion. Dice it tiny. Most people don't want a giant slab of onion in their slaw, but they need that bite for balance.
For the dressing, aim for 32 ounces of your preferred base.
This combo will yield approximately 10 pounds of finished coleslaw. This allows for the "4-ounce scoop" standard, with a little bit of a buffer for the people who go back for seconds.
Actionable Steps For Your Event
Start by auditing your menu. If you have four other sides (beans, potato salad, corn, and chips), you can safely reduce these numbers by 20%. If slaw is the only vegetable on the table, stick to the 10-pound rule.
Prep your cabbage and carrots the day before but store them in a zip-top bag with a dry paper towel. Do not add the dressing until 2 to 4 hours before the event. This strikes the perfect balance between flavor absorption and structural crunch.
If you end up with leftovers—which you might, if the weather is bad or people aren't hungry—don't toss them immediately. Leftover slaw that has gone a bit soft is a phenomenal addition to a stir-fry or as a base for a "crack slaw" egg roll bowl the next day. The vinegar and sugar in the dressing actually help caramelize the cabbage when it hits a hot pan.
Check your bowl size. You need a vessel that holds at least 8 to 10 quarts to mix 50 servings comfortably. Trying to mix 10 pounds of slaw in a standard salad bowl is a recipe for a messy kitchen floor. Use a clean plastic bus tub or a massive stainless steel mixing bowl. It makes the distribution of dressing much more even, ensuring that the person at the end of the line isn't just eating dry cabbage shreds.
