Steak burnt outside and underdone inside
The crust is past where anybody wants it and the centre has not arrived, which is a geometry problem rather than a skill problem.
Work out which one it is
Each cause below lists the signs that point at it rather than at the others. Start with the signs, not with the fix.
The steak is too thick to cross entirely over direct heat.
commonSigns it is this one
- The cut is around an inch and a half or thicker.
- The whole cook happened over the fire, with no cooler zone used.
Why it happens: Heat arrives at the surface and travels inward slowly. On a thick cut the surface reaches browning temperature and keeps going long before the centre has warmed, so the two endpoints cannot both be met on one zone.
What to do
- Move it to the fire-free side, put the lid on and bring the centre up there, then sear at the end. — during cook, partial
A crust that is already past browning will not improve, but the inside can still be saved.
- Reverse sear next time: bring the centre up gently first, then sear briefly at the end. — next time, reliable
This is what BBQHQ's ribeye profile describes, and the covering evidence there matters — a tented steak has been measured continuing to climb well past its target.
Next time
- Match the method to the thickness before lighting, not after the first side.
The fire is hot enough to char faster than any interior can catch up.
occasionalSigns it is this one
- The outside blackened within two or three minutes a side.
- The coal bed is fresh, deep and fully engaged.
Why it happens: A very hot bed browns the surface in a minute or two. On a thin steak that is exactly right; on anything thicker it converts the outside to carbon before conduction has moved the heat inward.
What to do
- Raise the grate or move to the edge of the fire, and slow down. — during cook, partial
