A few things worth knowing.

How long does whole lobster take in the grill?

For Whole lobster, 900 g; indirect heat, the chart baseline is 18-20 minutes at 320°F. Adjusted sizes and temperatures are modelled estimates.

What makes whole lobster cook faster or slower?

Measure the thickest part; thin tails finish before thick center portions. Thickness, initial temperature and appliance output also matter. A total basket weight does not describe the thickness of each piece.

Can I cook whole lobster from frozen?

This method has no supported frozen model. Thaw safely first and use the reference shape.

When should I start checking?

Check at 18 minutes for this setting. Keep cooking if the center has not reached the appropriate safety endpoint or texture. A timer is a reminder to check.

How do I know when whole lobster is done?

USDA specifies a doneness cue: shrimp, lobster, crab and scallops should be opaque and pearly or white. Bivalve shells must open; discard those that do not. A thermometer beats any timer.
