A 20-person burger cookout runs smoothly with 40 patties grilled in 4 rounds of 10. At this size, consider prepping patties the night before and storing them separated with parchment paper. Designate one person to manage the grill while another handles the serving table — it makes a real difference.

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.
