A whole fish cooked directly on campfire coals with minimal preparation is one of the finest things produced by fire. Here is the method — and why the char is part of the recipe.
Why Whole Fish on Coals
The outer skin and scales of a whole fish form a protective layer that insulates the flesh from the direct heat of the coals. The fish cooks in its own moisture — steam from inside the cavity circulates and cooks the flesh gently, while the coal contact gives the outside a char that adds flavour rather than burning the fish through. The result is moist, smoky, and completely different from grilling.
What Fish Works
Any whole fish with intact scales works — the scales are the insulation. Bream, snapper, barramundi, trout, and flathead all work well. The optimal size is 400g to 1kg — large enough to handle easily, small enough to cook evenly. A 3kg fish takes too long and dries out in the centre before the outside has finished.
Preparation
- Clean the fish — gut, gills out, rinse. Leave the scales on — they are essential to the method.
- Stuff the cavity with whatever aromatics you have: a cut lemon, fresh herbs (thyme, rosemary, fennel fronds), a crushed garlic clove, a knob of butter. These steam inside the fish and flavour the flesh from within.
- Score the skin 3–4 times on each side — this helps the cavity aromatics penetrate and allows even cooking through the thickest part.
- No oil on the outside. The fish goes directly on the coals — oil on a scaled fish serves no purpose.
On the Coals
Rake a bed of coals to the side of the fire — glowing but not flaming. Place the fish directly on the coals. It will sizzle immediately and the bottom surface will begin to char. Leave it. After 6–8 minutes (for a 600g fish), the flesh will have turned opaque two-thirds of the way up the side. Flip once with tongs. Cook the second side for 5 minutes.
The skin will be charred and will peel away easily, bringing the scales with it. The flesh beneath will be perfectly cooked, smoky, and extraordinary.
