Prices checked Oct 2026, average US grocery prices. Portions follow common catering rules of thumb; safe temperatures follow USDA. How we calculate

For 40 guests, 80 burger patties across two grills is the standard approach. Assign one grill to patties, the other to toasting buns — this nearly doubles your throughput. At this size, a build-your-own burger bar (condiments laid out in order: lettuce, tomato, onion, cheese, sauces) keeps the serving line moving fast.

When hot dogs are on the grill too, most guests take one of each, so you need fewer burgers. Kids lean toward hot dogs.

Cooking Details

Target temperature: 160°F internal (USDA, ground beef)

Cook time: 3–4 minutes per side over medium-high heat

Cooking tip: Form patties slightly wider than the bun because they shrink about 25% on the grill. A small dimple in the centre stops them puffing up.

Food safety: don't leave cooked meat out more than 2 hours, or 1 hour above 90°F (USDA). Keep hot food above 140°F.
