For a barbecue for a large group in 2026, plan on an average of 350–450 g of meat/fish per person (if it's the main meal), 250–350 g of vegetables, 150–250 g of side dishes, 30–50 g of sauce, and 1.5–2.5 L of drinks. If you'll have salads, appetizers, and dessert, you can reduce the meat to 300–350 g. Below is a checklist and table to quickly calculate purchases for N people without chaos.
1) Quick Calculation for N People: Formula and Standards
You can use this section as a "napkin calculator." Multiply the standard by the number of guests and add a small buffer if the group has hearty eaters.
- Meat/Poultry/Fish (main): 350–450 g/person. For a mixed menu (meat + vegetables + sides) — 300–400 g/person.
- Vegetables for grilling and fresh: 250–350 g/person (some will go into salad, some on the grill).
- Side dishes (potatoes/lavash/grains): 150–250 g/person cooked (or 200–300 g raw potatoes).
- Sauces and condiments: 30–50 g/person (ketchup, BBQ, garlic, adjika, etc.).
- Bread/lavash: 80–120 g/person (usually 1–2 lavash or 2–3 slices of bread).
- Drinks: 1.5–2.5 L/person (closer to the upper limit in hot weather). Of this, water — at least 0.7–1.0 L/person.
- Ice: 300–500 g/person if you're making cold drinks.
Buffer: for food +10% (if there are many men/teenagers — +15%), for water +20% in hot weather.
2) Table: How Much to Buy for 10, 20, and 30 People
This is a basic "barbecue shopping list for a large group" without exotic items: assorted meat, vegetables, sides, sauces, drinks, and supplies. Quantities are approximate and suitable for a "hearty outdoor meal" format.
Assumptions: 400 g meat/person, 300 g vegetables/person, 200 g sides/person (cooked), 40 g sauces/person, 2 L drinks/person.
| Category | Per Person | For 10 People | For 20 People | For 30 People |
|---|---|---|---|---|
| Meat/Poultry/Fish (raw weight) | 0.4 kg | 4.0 kg | 8.0 kg | 12.0 kg |
| Vegetables (fresh + for grilling) | 0.3 kg | 3.0 kg | 6.0 kg | 9.0 kg |
| Side dishes (cooked weight) or raw potatoes | 0.2 kg / 0.25–0.3 kg | 2.0 kg / 2.5–3.0 kg | 4.0 kg / 5.0–6.0 kg | 6.0 kg / 7.5–9.0 kg |
| Bread/lavash | 0.1 kg | 1.0 kg | 2.0 kg | 3.0 kg |
| Sauces (total) | 40 g | 400 g (1–2 jars) | 800 g (2–3 jars) | 1200 g (3–4 jars) |
| Drinks (total) | 2.0 L | 20 L | 40 L | 60 L |
| Water (included in drinks) | 0.8–1.0 L | 8–10 L | 16–20 L | 24–30 L |
| Ice (optional) | 0.4 kg | 4 kg | 8 kg | 12 kg |
If you plan lots of appetizers (cheese, chips, fruit) or a full table with salads, reduce the meat by 10–20% and add more vegetables/herbs.
3) Product Checklist: Meat, Marinades, and Portions Without Surprises
For a large group, an assortment works best: some guests prefer pork, some chicken, others ask for fish or vegetables. This way you're not dependent on one type of meat and it's easier to please everyone.
Meat Assortment (per person)
- Pork (neck/loin): 150–200 g
- Chicken (thighs/wings/fillet): 120–180 g
- Sausages/kupaty: 80–120 g
- Fish/seafood (optional): 120–180 g instead of part of the meat
How to assemble 8 kg of meat for 20 people: 3.5 kg pork + 2.5 kg chicken + 2.0 kg sausages. If you have fish, replace 1–1.5 kg of any item with it.
Marinade: How Much You Need and the Logic Behind It
- Marinade by volume: 80–120 ml per 1 kg of meat (usually enough if the meat is good quality).
- Salt: 12–16 g per 1 kg (about 2–2.5 tsp without a heap) — better to salt in advance and evenly.
- Onions: 150–250 g per 1 kg (if you like the classic "onion" style).
- Acid (lemon/vinegar/kefir): moderately, so as not to "cook" the meat. For poultry, you can use a bit more; for pork, be careful.
For convenience in shopping, calculate like this: for 8 kg of meat, take 1.5–2 kg of onions, 3–5 lemons or 0.5–1 L of kefir (if making a fermented milk marinade), spices, and salt.
Salt, Spices, and "Non-Obvious" Additions
- Salt, black pepper, paprika, dried garlic, cumin/coriander (to taste).
- Vegetable oil for grilling vegetables: 50–80 ml per 1 kg of vegetables.
- Herbs: 30–50 g per person (parsley, dill, cilantro, green onions).
- Lemons: 1 per 4–5 people (for drinks, fish, vegetables).
4) Vegetables, Salads, and Side Dishes: What People Actually Eat Outdoors
If you're looking for "what to buy for a barbecue outdoors," vegetables are what runs out unexpectedly fast, especially in summer. Make a mix: some fresh, some for grilling.
Vegetables (standard 250–350 g/person)
- For grilling: zucchini/eggplant 80–120 g, peppers 60–100 g, mushrooms 60–100 g, corn 1 cob per 3–4 people.
- Fresh: cucumbers 60–100 g, tomatoes 80–120 g, radishes/lettuce leaves in season.
Practice: for 20 people, take about 2–2.5 kg of vegetables for grilling + 3–3.5 kg fresh (total about 6 kg).
Side Dishes (standard 150–250 g/person)
- Potatoes: 250–300 g raw per person (baked in foil or on the grill).
- Lavash/pita: convenient for "assembling" shashlik with vegetables; 1–2 sheets per person.
- Grains/pasta salad: if you want a more "table-style" format, 60–80 g dry product per person.
5) Sauces, Drinks, and Dessert: Standards by Jars and Liters
In a large group, sauces and drinks are what run out before the meat. Better to take a bit more water and ice than to look for a store later.
Sauces (30–50 g/person)
- Ketchup/tomato: 1 jar 400–500 g per 10–12 people.
- BBQ: 1 jar 400–500 g per 15–20 people (if it's not the only sauce).
- Garlic/yogurt: 300–400 g per 10–12 people.
- Mustard/adjika: 1 small jar each per 15–20 people.
Optimal: 2–4 different sauces in small quantities instead of one huge one.
Drinks (1.5–2.5 L/person) and Breakdown
- Water: 0.8–1.0 L/person minimum (still/sparkling).
- Non-alcoholic drinks: 0.5–1.0 L/person (lemonade, fruit drink, tea in a thermos).
- Alcohol (if appropriate): guideline 0.3–0.6 L beer/person or 150–250 ml wine/person, but adjust to the group and format.
Ice: if it's hot and you're making drinks with ice, take 8–12 kg for 20 people. In 2026, summer picnics are increasingly happening on hot days — water and ice really save the day.
Dessert and Fruit (optional)
- Fruit: 150–250 g/person (watermelon/melon/grapes/apples).
- Marshmallows/cookies: 30–50 g/person if there's a campfire/grill.
6) Charcoal, Disposable Tableware, and Logistics: So the Barbecue Doesn't Fail
This section is about what's often forgotten when making a shopping list for a picnic or shashlik. For a large group, it's better to plan "consumables" with a buffer right away.
Fuel and Fire
- Charcoal: 1.5–2.0 kg per 1 hour of active grilling on a medium grill. For 20 people, you usually need 6–10 kg (depending on the grill and speed).
- Lighter fluid: 1 bottle 0.5 L for 1–2 outings (or natural cubes).
- Firewood: if you need a campfire/atmosphere — 1 bundle or 10–15 kg.
Tableware and Small Items
- Plates: 2 per person (for hot food and salad).
- Cups: 2 per person (for water and drinks).
- Forks/spoons: 1–2 sets per person.
- Napkins: 10–15 per person + a roll of paper towels.
- Trash bags: 3–6 sturdy ones (60–120 L), better to have extra.
- Foil and parchment: 1–2 rolls (potatoes, corn, fish).
- Disposable gloves: 1–2 pairs for whoever marinates/serves.
- Hand sanitizer, wet wipes, band-aids: a mini kit is always a plus.
How to Quickly Distribute Purchases Among People
To avoid buying three identical ketchups and forgetting charcoal, divide the list into blocks: "meat and marinade," "vegetables and herbs," "drinks and ice," "consumables." It's convenient to keep a shared list in the Pickt mini-app in Telegram: add items, mark what's bought, and everything syncs in real time among participants (bot: t.me/PicktBot/app).
Bottom line: a good barbecue shopping list for a large group isn't just about meat. Keep the guideline of 350–450 g of the main product per person, 250–350 g of vegetables, and 1.5–2.5 L of drinks, then adjust for weather, guest ages, and appetizers. With the table above, you'll quickly calculate purchases for 10, 20, or 30 people and won't overpay for extras.
Frequently Asked Questions
How much meat per person for shashlik if there are salads and appetizers?
Usually 300–350 g of raw meat per person is enough. If the group is very active and appetites are stronger outdoors, keep it at 350–400 g.
What buffer should I plan for a large group?
For food — +10% of the calculation, for water — +20% in hot weather. If some guests "don't eat meat," better to increase vegetables and sides rather than the total meat volume.
What to buy for a barbecue outdoors if there's no time for long cooking?
Take quick items: sausages/kupaty, chicken wings, mushrooms, peppers, lavash, ready-made sauces, vegetables for fresh cuts. Buy charcoal and disposable tableware in advance so you don't have to look for them on site.
How not to forget consumables and distribute purchases among participants?
Break the list into 4 blocks (food, drinks, consumables, "grill and fire") and assign responsible people. For a shared list, Pickt is convenient: everyone sees current items and "bought" marks, which especially helps when shopping in different stores.
