How to Pull Off Raclette for a Crowd
Raclette is the kind of meal that was practically invented for big gatherings — a table full of people, a steady flow of melted cheese, and nobody leaves early. But scaling up from a cosy dinner for four to a raclette party for a large group of 15, 20 or even 30 guests takes a bit more planning than simply buying more cheese. Get the numbers wrong and you end up with cold potatoes, queuing guests and a single overworked grill. Get them right and the evening runs itself.
This guide covers the exact quantities, the equipment math, the logistics and a full checklist so your next big raclette is as relaxed for you as it is for your guests.
How Much Food per Person: The Core Quantities
The most common question is simple: how much raclette cheese per person? The standard answer is 200–250 g of cheese per adult for a full meal. For a party of 10 expect to prepare 2–2.5 kg; for 20 guests, 4–5 kg; for 30 guests, 6–7.5 kg. If cheese is just one of several courses, shave 20–25% off those numbers.
Potatoes are the anchor of the plate. Allow 3–4 medium potatoes per person (roughly 300–350 g unpeeled), boiled or jacket-cooked in advance. For 20 guests that is around 6–7 kg of potatoes — well worth cooking the night before and reheating in the oven in batches.
For charcuterie and accompaniments, the rule of thumb used by caterers is 80–100 g of cured meats per person: a mix of ham on the bone, dried beef (viande des grisons), saucisson and coppa works well. Round out the table with pickled cornichons, silverskin onions and a green salad — quantities here are forgiving, so err on the generous side.
A quick reference table for common party sizes:
- 10 guests: 2 kg cheese · 3 kg potatoes · 900 g charcuterie
- 15 guests: 3 kg cheese · 4.5 kg potatoes · 1.3 kg charcuterie
- 20 guests: 4.5 kg cheese · 6.5 kg potatoes · 1.8 kg charcuterie
- 30 guests: 7 kg cheese · 10 kg potatoes · 2.7 kg charcuterie

How Many Raclette Grills Do You Need?
Most household electric raclette grills seat 8 people comfortably — each guest gets their own coupelle (individual tray) and the cheese melts evenly across all positions. The practical rule: one grill for every 6–8 guests. That means:
- 10 guests → 2 grills (avoids a bottleneck and keeps service flowing)
- 16 guests → 2 grills (using 8-person models)
- 20–24 guests → 3 grills
- 30 guests → 4 grills
If you only own one grill and are borrowing the rest, match the wattage as closely as possible (most standard grills draw 1,200–1,500 W). Mixing a 600 W entry model with a 1,400 W workhorse means half the table waits while the other half eats.
For parties above 20, consider a half-wheel raclette setup as an alternative or complement. A traditional half-wheel of Valais raclette (typically 3–3.5 kg) held under a dedicated raclette machine can scrape cheese directly onto plates at a rate of roughly 25–30 portions before it needs replacing. It creates a visual centrepiece and is often faster for very large groups, though it requires one dedicated person to operate it throughout the evening.

Logistics: Tables, Power and Service Flow
The single biggest mistake at large raclette parties is underestimating power supply. A 1,400 W grill running continuously for two hours is not a problem on its own. Three or four of them running simultaneously on the same circuit is a tripped breaker waiting to happen.
Electricity checklist:
- Identify which breakers serve the rooms you are using and note their amperage (a standard 16 A circuit handles roughly 3,500 W — about two grills maximum).
- Spread grills across at least two separate circuits; use a short heavy-duty extension lead if needed rather than a long thin one (voltage drop reduces performance).
- Test the setup at least 30 minutes before guests arrive.
Table and seating layout matters too. For groups of 20+, long banquet tables work better than round ones — grills can sit in the centre at regular intervals with guests on both sides. Plan for roughly 60 cm of table width per grill plus 40 cm each side for plates, glasses and food. Keep the cheese and charcuterie platters on a separate side table to avoid crowding around the grills.
Service timing: stagger the start of each grill by 10–15 minutes if your kitchen can only handle so many simultaneously. Pre-cut the cheese into even 5–7 mm slices before guests arrive — it speeds up service enormously and prevents uneven melting. Boil potatoes in batches, keep them hot in a low oven (80–90 °C) on baking trays covered with foil.

Budget Planning for Large-Group Raclette
Raclette is inherently one of the more cost-efficient crowd meals because the ingredients are simple and the cooking is shared. A rough per-head budget in Western Europe or North America:
- Economy (supermarket raclette block): €8–12 / person
- Mid-range (mixed quality cheeses, decent charcuterie): €14–18 / person
- Premium (AOP Valais or Obwalden half-wheel, artisan charcuterie): €22–30 / person
Equipment rental is worth considering for one-off large parties. Many kitchen-equipment hire companies will rent multi-person raclette grills for €15–30 per grill per night. For 30 guests needing four grills that is €60–120 — usually cheaper than buying equipment you will use once a year.
Wine pairings scale simply: one bottle of dry white (Fendant, Chasselas or Pinot Gris) per 2–3 guests as a baseline, supplemented by sparkling water. For full wine guidance see our wine pairing with raclette article.
Keeping Everything Hot Throughout the Evening
A large raclette dinner is not a race to the table — it typically lasts 90 minutes to two-and-a-half hours, and the challenge is keeping food at temperature across that span.
- Potatoes: keep in a foil-covered tray in the oven at 80 °C, refresh with a small splash of water every 45 minutes to prevent drying out.
- Cheese: leave blocks at room temperature for 30 minutes before the meal; cold cheese takes longer to melt and creates uneven browning.
- Charcuterie: bring out in smaller batches (enough for 45–60 minutes of eating) rather than all at once — it stays fresher and the table looks more inviting for second helpings.
- Serving plates: warm your dinner plates in a low oven or dishwasher before service. This alone makes a noticeable difference to how quickly the food cools once it hits the plate.
Large-Group Raclette Checklist
Print this off and stick it on the fridge:
- Calculate cheese at 200–250 g per person; buy 10% extra as buffer
- One grill per 6–8 guests; test all grills the day before
- Map your power circuits; no more than two 1,400 W grills per 16 A circuit
- Pre-slice cheese 5–7 mm the morning of the event; keep covered and refrigerated
- Boil potatoes in batches; hold in a foil-covered oven tray at 80 °C
- Warm all dinner plates before service
- Stagger grill starts by 10–15 minutes on large multi-table setups
- Lay out charcuterie in 45-minute serving batches
- Have a backup circuit breaker plan
- Put someone in charge of each grill station

Frequently Asked Questions
How much raclette cheese do I need for 20 people?
For 20 people eating raclette as a main meal, budget 4–4.5 kg of raclette cheese. If you are offering multiple courses alongside, 3.5 kg is usually sufficient. Always slice the cheese in advance for faster service.
How many raclette machines do I need for a party of 20?
You need 3 raclette machines for 20 people (one per 6–8 guests). Use three 8-person grills or a combination of tabletop grills — and make sure they are spread across at least two separate electrical circuits to avoid tripping a breaker.
Can I use a half-wheel raclette machine for a large group?
Yes — a half-wheel raclette machine is excellent for large groups because it produces portions quickly and creates a great focal point at the table. One 3–3.5 kg half-wheel feeds roughly 25–30 people. The trade-off is that it requires a dedicated operator and cannot be left unattended the way tabletop grills can.
How do I keep raclette hot for 30 guests over a long dinner?
Keep boiled potatoes covered in foil in a low oven at 80 °C, warm your dinner plates before service, and bring cheese to room temperature before guests arrive. Serve charcuterie in batches rather than all at once — it stays fresher and maintains table appeal throughout the evening.
