Family Reunion BBQ Menu Planning

Quantities for every protein and side, grill capacity planning for 30 to 100 guests, a timing schedule to get everything ready at once, and side dish ratios that balance the spread.

BBQ Quantities by Guest Count

These quantities assume one main meal with seconds available. Add 15% buffer for outdoor summer events where appetites run high. Use Reunly's food calculator for exact quantities by headcount.

Grill Sizing Guide

The most common BBQ mistake at large reunions: underestimating the grill capacity and having hungry guests wait 45 minutes. Match your grill to your guest count.

Standard backyard kettle grill (22")

Capacity: About 12–15 burgers or 8 chicken pieces at once

Best for: Reunion under 20 people

Note: For 30+ guests, you need multiple grills or a much larger unit

Large cart grill (36"–48" cooking surface)

Capacity: About 25–35 burgers or 16 chicken pieces at once

Best for: Reunion of 30–60 people

Note: Plan for 2 hours of active grilling to feed 50 people burgers

Offset smoker / barrel smoker

Capacity: Varies widely — typically 30–60 lbs of meat in one batch

Best for: Pulled pork and brisket for large groups

Note: Requires a pitmaster — smoking is a full-day commitment

Rented commercial flat-top grill

Capacity: Can cook 60+ burgers simultaneously

Best for: Reunion of 80–200 people

Note: Rental runs $150–350/day from an equipment company; requires propane

Hired BBQ catering trailer

Capacity: Professional-grade smoker and grill; handles 100–500 people

Best for: Large reunions of 100+ where you don't want to manage the grill

Note: All-in catering service; runs $22–32/person including all sides

BBQ Timing Plan (12 PM Serving Target)

The hardest part of a BBQ reunion is timing everything to be ready at the same moment. Low-and-slow smoked meats can't be rushed — plan backwards from your serving time.

Night before

Apply dry rub to brisket and pork shoulder. Prep side dish ingredients. Chill coleslaw overnight.

5–6 AM

Start smoker. Put on brisket and pork shoulder. These need 12–16 hours at 225°F.

10 AM

Prep burger patties, season, and refrigerate. Set up serving table, chafing dishes, and sides.

11 AM

Start chicken halves on the grill. Chicken takes 45–60 minutes. Baste with sauce at the 30-minute mark.

11:45 AM

Pull brisket and pork off the smoker. Rest meat for 30–45 minutes before slicing/pulling. Start burgers and dogs.

12:00 PM (serving time)

Everything should be ready: smoked meats rested, chicken off, burgers hot. Open the buffet line.

During service

Keep a grill going for additional burgers and dogs as needed. Replenish chafing dishes every 30 minutes.

Side Dish Ratios and Roles

A great BBQ spread has a balance of hot sides, cold sides, and refreshing items. Each side plays a different role in the meal.

Baked beans

Anchor side

Per person: 4 oz per person

Slow cooker or chafing dish — stays warm easily

Mac and cheese

Crowd favorite

Per person: 4–5 oz per person

Two smaller pans beat one large pan for even reheating

Coleslaw

Refresher / palate cleanser

Per person: 3–4 oz per person

Keep cold — ice bath essential in summer heat

Corn on the cob

Finger food / festive

Per person: 1–1.2 ears per person

Grill or boil; keep in a large foil pan covered with foil

Potato salad

Filling starch

Per person: 4–5 oz per person

Keep cold — do not leave in sun; 2-hour rule applies strictly

Watermelon

Dessert / hydration

Per person: 1/12th of a melon per person

Cut at the event; 1 whole melon serves about 12–15 people

Frequently Asked Questions

How many pounds of BBQ do I need per person at a family reunion?

Plan for 6–8 oz of cooked meat per adult for a single serving. Since people usually take seconds at a reunion, budget 10–12 oz of cooked meat per adult. For raw meat, account for a 30–40% loss during cooking: to serve 6 oz cooked, start with 9–10 oz raw. For a mixed crowd of adults and kids, use a blended rate of about 8 oz cooked per person. Round up — running out of BBQ at a reunion is a memory nobody wants.

How many burgers do I need for a family reunion of 50 people?

For 50 people at a main cookout meal, plan for 65–70 burger patties (1.3–1.4 per person, accounting for the people who take two and the kids who take half). Use 1/3 lb patties for adults. Have 10–15 additional patties in reserve in case of high demand. For a family reunion with a mix of burgers and hot dogs, plan 1 burger + 1 hot dog per person as a baseline, then adjust based on your crowd's preferences.

How do I time a BBQ grill for a large family reunion?

Work backward from your target serving time. Smoked meats (brisket, pork shoulder) need 1–1.5 hours per pound at 225°F — start these the night before or very early morning. Chicken halves take 45–60 minutes on a medium grill. Burgers and hot dogs take 10–15 minutes. For a noon lunch: start smoked meats by 6 AM, put chicken on at 11 AM, and save burgers and dogs for the final 15 minutes. Use a meat thermometer to confirm doneness rather than relying on time alone.
