Group cooking fails on throughput, not on recipes. One burner serving twelve people means ninety minutes of cooking and a queue. The fix is structural: two burners, one pot meal, cook in batches, and serve in waves rather than all at once.
Headcount and quantities
| People | Main dish | Side | Water for cooking |
|---|---|---|---|
| 4 | 2 lb | 3 cups dry | 2 L |
| 8 | 4 lb | 6 cups | 4 L |
| 12 | 6 lb | 9 cups | 6 L |
| 20 | 10 lb | 15 cups | 10 L |
Rule of thumb: 8 oz of protein per person, 1 cup of dry starch, and 2 cups of vegetables. Add 20% if the group has been hiking.
Pot size
| Pot | Serves | Note |
|---|---|---|
| 2 qt | 2–3 | Solo or couple |
| 4 qt | 4–6 | Small family |
| 6 qt | 8 | Group minimum |
| 8 qt | 10–12 | Two-burner needed |
| 12 qt | 20 | Car camping only |
A pot should be no more than two-thirds full when boiling. An 8 qt pot filled to the rim takes three times as long to boil and spills on the first stir.
Throughput
| Setup | Burgers per 20 min |
|---|---|
| One burner, 10 in pan | 4 |
| Two burners, two pans | 8–10 |
| Griddle over coals | 12 |
| Dutch oven, stew | 20 servings in one pot |
The fastest group meal is always a one-pot stew or chilli: no plating, no queue, no timing. Burgers look better in photographs and are the slowest thing you can cook for a crowd.
Menu plan
| Meal | Group-friendly dish |
|---|---|
| Breakfast | Oats with toppings, or burritos |
| Lunch | Sandwiches, pre-made wraps |
| Dinner | Chilli, curry, pasta, fajitas |
| Snacks | Fruit, nuts, trail mix |
Choose dishes that hold: a chilli can sit for 30 minutes, a steak cannot. Avoid anything that needs individual attention at the moment of serving.
Cost per person
| Menu | Per person per day |
|---|---|
| Chilli and rice | $4–6 |
| Pasta and sauce | $3–5 |
| Fajitas | $6–8 |
| Burgers and sides | $7–10 |
| Pre-made dehydrated meals | $12–18 |
Buying in bulk and cooking one pot per meal is roughly half the cost of individual portions.
Cleanup plan
| System | How |
|---|---|
| Wash stations | Three tubs: wash, rinse, sanitise |
| Assign roles | Cook does not wash |
| Disposable plates | Acceptable for large groups |
| Burnable paper | Only where fires are allowed |
| Grey water | Strain, pack out |
A roster works: two people cook, two wash, two collect trash and tidy. The same people doing both is how group trips sour.
Timing a group dinner
| Time before eating | Action |
|---|---|
| 90 min | Light fires or stoves, start water |
| 60 min | Start the long-cook element |
| 30 min | Add quick ingredients |
| 10 min | Set out plates, call people |
| 0 | Serve in waves |
Serving in waves means the first eight eat while the next eight are served. Food stays hot in the pot, and nobody waits twenty minutes with a plate.
Assigning the work
Feeding twenty people is three jobs: cooking, serving, cleaning. Assign them before the trip, not at dinner. Two cooks, two servers, two washers is the minimum for a group of twenty, and rotating the roles each night keeps it fair.
The person who cooked should not wash up. That single rule prevents most of the resentment that builds on group trips.
What scales badly
| Item | Problem |
|---|---|
| Individual steaks | Timing, pan space |
| Pancakes for 20 | One at a time |
| Custom orders | Queue |
| Salads | Wilt while serving |
| Anything fried | Oil volume, smoke |
One pot that works for twenty
| Ingredient | Amount | Note |
|---|---|---|
| Onion | 3 | Pre-chopped |
| Mince or beans | 5 lb / 6 cans | Brown first |
| Tinned tomatoes | 6 cans | — |
| Stock | 3 L | — |
| Rice | 8 cups dry | Cook separately if pot space is tight |
| Spices | Pre-mixed | One bag |
Two pots and two burners: one for the main, one for rice. That is the whole logistics of feeding twenty.
Water is the hidden constraint
Cooking for twenty needs 10 L of water for food alone, plus washing. If the site has one tap, fill containers in the morning rather than at dinner time when everyone else is queuing.
Keep a backup meal
One extra one-pot meal in the box covers a rained-out cook, a late arrival, or a dish that burns. For twenty people, that is cheap insurance.
