BBQ party plannersmoking for a crowd in a British garden

"We've got twenty people coming on Saturday and one smoker. What do we cook?" Every smoker owner hears some version of it by June, and the answer is shorter than people expect: one big, slow, forgiving cook that does the heavy lifting, and one quick cook that fills the gaps. Everything else is planning, and most of the planning happens the day before.

One big cook, one quick cook

The big cook should be something that tolerates a late start, a temperature wobble and a long rest. Pork shoulder wins this every time. It's cheap at any butcher, it feeds a lot of people, pulled pork goes into a bap with no ceremony at all, and it holds hot for hours wrapped in a cool box. Brisket is the obvious rival, but it's dearer, less forgiving, and the party with the dry brisket is the one people remember.

The quick cook is your insurance and your crowd-pleaser for early arrivals. Good options:

Resist the urge to do four meats. A single smoker has limited space, and every extra cut means another probe, another set of timings and another thing to go wrong while you're meant to be talking to your in-laws.

How much to buy

Raw weight isn't what lands on the plate. A pork shoulder loses a good chunk of its weight to fat, bone and moisture, so buying "200 g a head" of raw shoulder leaves people hungry. The calculator below does the yield maths for you. Set the number of guests, pick your cuts and adjust the portion if your crowd are big eaters or it's a buffet with plenty of sides.

Build my party plan

Round up rather than down. Leftover pulled pork freezes well and makes Monday's lunch; running out at 7pm makes a story.

Work back from when you serve

The single biggest mistake with a party cook is planning forward from when you get up. Plan backwards from when people eat. Our pulled pork guide works on roughly 2.5–4 hours per kg at around 110–120°C, and a 4 kg shoulder can therefore take anything from ten to sixteen hours before the rest. That range is the reason the planner gives you a window, not a time.

The command centre above carries your calculated butcher order straight into the timeline. Change the serving time there and it rebuilds the day without making you type the joint weight twice.

Aim to light at the early end of the window. A shoulder that finishes three hours early is a non-event: wrap it, towel it, cool box it, and it will still be hot when you pull it. A shoulder that's stalled at 4pm with guests arriving at 5 is a genuine problem. More on why in resting smoked meat.

The quick cook goes on later, timed to come off just before serving. Most cooks find the smoker has room once the shoulder is wrapped, which is handy.

Keeping food hot, safely

Hot food needs to stay hot, and cold food needs to stay cold. The FSA guidance on hot-holding and on how long cooked food can sit out is the thing to follow here; check it before the day rather than guessing. In practice:

• Big cuts hold best wrapped in foil, then a towel, in a dry cool box. Check with a probe before serving that the meat is still hot enough by the FSA guidance.
• Pulled meat cools faster once it's shredded, so pull it close to serving, not an hour before.
• Buffet tables in the sun are the weak spot. Put out smaller portions and top up from the hot cool box rather than leaving one big tray out all afternoon.
• Leftovers want cooling and into the fridge promptly, again by the FSA guidance. Don't leave the remains of the pork on the table until the last guest leaves at midnight.

A decent probe thermometer earns its keep here as much as during the cook.

Sides you can make the day before

Anything that can be made on Friday should be. Coleslaw is better after a night in the fridge. Potato salad, pasta salad, pickled red onions, a big tray of beans to reheat, a jar of BBQ sauce: all of these keep. Buy the baps on Saturday morning and leave the lettuce until the last minute.

The rule is simple: on the day, the only things that should need a hob or a knife are the meat and maybe a green salad. Your oven is a perfectly good hot cupboard for the beans.

Plan B for rain

This is Britain, so there's a rain plan whether the forecast says so or not. The important part: the people shelter, the smoker doesn't. Never put a charcoal, wood or pellet smoker under a gazebo, a garage door or a patio awning with low sides. Carbon monoxide and fabric fires are both worse than wet charcoal.

Leave the smoker in the open, accept it will burn more fuel, and keep a golf umbrella for the cook when checking the probe. Put the gazebo up over the serving table and seating instead. Smoking in the rain covers keeping the fire steady through a downpour.

Vegetarian guests

Plan for them rather than handing over a bread roll and an apology. Halloumi, peppers, courgettes, mushrooms and corn all take smoke beautifully and cook in well under an hour. Our guide to smoked vegetables and halloumi has the details. Cook them on a separate rack or tray, above or away from the meat so nothing drips onto them, and use separate tongs.

The party checklist

The day before

1. Buy the meat and fuel; get more charcoal or pellets than you think you need.
2. Rub the shoulder, wrap it and put it back in the fridge.
3. Make the slaw, salads, sauce and beans.
4. Charge the thermometer and clear a space in the fridge for drinks.
5. Check the forecast and decide where the gazebo goes.

The morning

1. Light the smoker at the early end of your planner window.
2. Let it settle at temperature before the shoulder goes on.
3. Shoulder on, probe in, lid shut.
4. Clean the cool box and dig out old towels for the rest.

The afternoon

1. Wrap the shoulder if it stalls and you're behind.
2. When it's tender, wrap and rest it in the cool box.
3. Quick cook and vegetables on, timed to finish just before serving.
4. Lay out cold sides from the fridge at the last moment.

Serve

1. Probe the meat to check it's still hot, then pull it.
2. Put out small trays and top up from the cool box.
3. Chill leftovers promptly.

Your next step is to put your guest count into the meat calculator and ring the butcher, especially for a summer weekend when shoulders sell out.

FAQs

How far ahead should I order the meat?

Aim for a week ahead for a big party in summer, and more for a bank holiday weekend. Butchers can also bone, roll or trim for you if you ask in advance.

Can I cook the pork the day before and reheat it?

Yes, and plenty of people do for big parties. Chill it quickly after cooking, then reheat it until it's steaming hot all the way through, following the FSA guidance on reheating.

What if the shoulder isn't done when guests arrive?

Bring out the quick cook and the sides first, wrap the shoulder and nudge the smoker temperature up a little. This is exactly why the plan starts early.

Do I need a second smoker for a big party?

Usually not. One shoulder or two side by side plus a quick cook fits most smokers. Your kettle BBQ can handle the sausages if space gets tight.
