Greek Grilled Octopus Recipe (Htapodi sta Karvouna)

Octopus hanging on a line in the sun outside a taverna is one of the standard images of Greece, and the drying does genuinely help. But the thing that actually makes octopus tender is much less romantic: a long, slow, gentle simmer before it ever sees a fire.

Octopus muscle is dense collagen. Below about 75C, held for long enough, that collagen turns to gelatin and the flesh becomes silky. Over high heat it seizes and turns to rubber. So the grill is not the cooking step at all, it is the finishing step, and it should take four minutes.

The other thing worth knowing is that you add no water to the pot. Octopus releases a great deal of its own liquid, and that liquid is the poaching medium and is far more flavourful than water would be.

Key preparation steps

1. Simmer the octopus in its own released liquid, with no water added.
2. Cook until a knife slides into the thickest part with no resistance.
3. Cool it in its liquid so it does not tighten.
4. Grill hard and fast for colour only, then dress while warm.

Do you need to tenderise octopus first?

Not if you simmer it properly. The traditional methods, beating it against rocks, dipping it three times in boiling water, adding a wine cork to the pot, are folklore of varying usefulness. The cork does nothing. The beating genuinely breaks down muscle fibre but is unnecessary for anything you buy.

What does work reliably is buying frozen octopus, or freezing fresh octopus for at least 48 hours before cooking. Ice crystals rupture the muscle structure and the result is measurably more tender. Most octopus sold outside coastal Greece has been frozen already, which is a genuine advantage here.

After that, the simmer does everything. Give it time and it will be tender.

Why no water in the pot?

Put an octopus in a dry heavy pan over a low heat with the lid on and within ten minutes it will have released a surprising amount of purple liquid, easily enough to poach itself in.

That liquid is concentrated octopus stock. Adding water dilutes it and gives you blander meat and a wasted opportunity. Some cooks add a splash of red wine, a bay leaf and a few peppercorns, which is worth doing.

Do not salt it during the simmer. Sea creatures are already saline and the liquid reduces considerably.

How do you know when it is done?

A thin knife or a skewer pushed into the thickest part of a tentacle, where it meets the head, should slide in and out with no resistance at all. If there is any springiness or grip, keep going.

For a 1.5 kg octopus this usually takes 50 to 70 minutes at a bare simmer. Size varies enormously so the knife test matters more than the clock.

Then let it cool in its own liquid rather than lifting it straight out. Octopus tightens if it cools in air, and half an hour sitting in the warm liquid keeps it relaxed.

The grill, and the dressing

The fire should be fierce and the octopus should be on it for no more than four minutes total. You are looking for charred edges and a little crisping on the suckers, not further cooking. Brush with oil first so it does not stick.

The dressing is olive oil, red wine vinegar and dried oregano, in roughly three to one, whisked and poured over while the octopus is still hot so it absorbs. Lemon instead of vinegar is common but vinegar is the more traditional and stands up better to the char.

Serve with a glass of ouzo or tsipouro, which is not a garnish but genuinely the intended pairing, and with fava or a plate of horta.
