3cm Lamb Chop: Grill at 220-260°C (425-500°F) for 4-5 min/side per side (medium).
Thick-cut lamb chops. Excellent for achieving a dark crust with a pink, juicy interior. The extra thickness gives you more margin for error.
| Doneness | Time Per Side |
|---|---|
| Rare | 3-3.5 min/side |
| Medium-Rare | 3.5-4 min/side |
| Medium | 4-5 min/side |
| Medium-Well | 5-6 min/side |
Grill temperature: 220-260°C (425-500°F)
Thickness is the single most important factor in determining cook time on the BBQ. A flat 300g steak that's 1cm thick cooks in 4 minutes total. A 300g steak that's 4cm thick needs 12+ minutes. Same weight, completely different cook times.
Heat travels from the surface inward. The thicker the cut, the longer it takes for the centre to reach your target temperature. This is why a meat thermometer is essential — time is just a guide.
Get precise cooking times for any meat, cut, and method. Never over-cook or under-cook your BBQ again.
