Quick Answer
For 20 people, you need 10 cups. This provides about 10 servings, assuming 0.5 servings per person.
Estimated cost: $5 - $15
How We Calculate
We use the industry-standard formula for coleslaw calculations:
-
Each person eats approximately 0.5 cups
-
Formula: 20 people × 0.5 servings ÷ 1 = 10 cups

Tips for Ordering Coleslaw Servings
- Make dressing ahead but toss just before serving
- Offer both creamy and vinegar-based versions
- Keep refrigerated until serving
- Pre-shredded cabbage saves prep time
- Can be made up to 4 hours ahead
Planning Guide: Coleslaw Servings for Your Event
The creamy versus vinegar-based coleslaw divide runs deeper than mere regional preference - it affects food safety, shelf life, and pairing compatibility. Creamy coleslaw made with mayonnaise requires constant refrigeration and should not sit at room temperature for more than 2 hours, making it risky for outdoor summer events. Vinegar-based slaws are more forgiving and can safely sit out for 3-4 hours because the acidity inhibits bacterial growth. However, creamy coleslaw pairs better with pulled pork and fried chicken because the richness complements the protein, while vinegar slaw's acidity cuts through fatty meats like ribs. The smart compromise for parties is offering both: make a smaller portion of creamy slaw for those who prefer it and a larger portion of vinegar slaw that can handle outdoor conditions. Vinegar slaw actually improves as it sits and can be made up to 24 hours ahead, while creamy slaw is best made 2-4 hours before serving.
Pre-shredded cabbage from grocery stores seems like an obvious time-saver but comes with tradeoffs. Bagged coleslaw mix is washed, dried, and ready to use, saving 20-30 minutes of prep time for large batches. However, it costs 3-4 times more per pound than whole cabbage and has a shorter shelf life because the shredding process damages cell walls, accelerating deterioration. For parties under 30 people, bagged mix is worth the convenience. For larger events, buying whole cabbage heads and shredding them yourself (or recruiting a helper) saves significant money. A food processor with a shredding disk makes quick work of whole heads - one medium cabbage yields about 8 cups shredded and serves 12-16 people. Mix green and purple cabbage for visual interest at a ratio of 3:1. Add shredded carrots for color and sweetness - the beta-carotene in carrots also helps the slaw maintain its fresh appearance longer.
Coleslaw dressing timing is the detail that separates soggy disappointment from crispy perfection. Never dress coleslaw more than 4 hours before serving, even for vinegar-based versions. The salt and acid in dressing draw moisture from cabbage through osmosis, creating a watery pool at the bottom of your bowl and limp, sad vegetables on top. Make your dressing up to 3 days ahead and store it separately, then toss with shredded vegetables 2-4 hours before the party. This timing allows flavors to meld without destroying texture. For events longer than 3 hours, use the two-bowl technique: dress half your coleslaw and refrigerate the other half undressed, then combine them halfway through the event for a texture refresh. When serving buffet-style, use a slotted spoon so excess liquid stays in the bowl rather than making plates watery. Include a small 'drain bowl' at the serving station for the first spoonful where excess dressing can drip off.
