Grilled Octopus with Lemon and Oregano

Greek Fast With Fish Published January 13, 2026

Grilled octopus is one of the defining dishes of the Greek islands — tender tentacles charred over high heat, dressed with nothing more than olive oil, lemon, and oregano. Getting octopus tender requires one counterintuitive step: braising it low and slow before it ever touches the grill. The grill then provides char and smokiness to the already-tender flesh. Skip the braising and you will be chewing rubber.

Octopus is a shellfish and is permitted on all fasting days, but on fish days when you can pair it with a glass of wine, this dish becomes transcendent.

FASTING LEVEL: Fast With Fish
SERVINGS: 4
TIME: 1 hour 15 minutes

INGREDIENTS

- 1 whole octopus (about 1-1.5 kg), cleaned (ask your fishmonger)
- 100ml extra-virgin olive oil
- Juice of 2 lemons
- 2 tablespoons red wine vinegar
- 2 teaspoons dried Greek oregano
- 4 cloves garlic, minced
- Salt and freshly cracked black pepper
- 1 bay leaf
- Fresh flat-leaf parsley, chopped
- Lemon wedges, for serving

METHOD

1. Place the cleaned octopus in a large pot with the bay leaf. Do not add water — the octopus will release its own liquid. Cover and cook over the lowest possible heat for 45-55 minutes until a knife slides easily into the thickest part of a tentacle.

2. Remove the octopus and let it cool slightly. Cut into individual tentacles. Pat dry with paper towels — dry octopus chars better.

3. Preheat a grill or grill pan to very high heat. Brush the tentacles with olive oil.

4. Grill the tentacles for 2-3 minutes per side until charred and slightly crispy on the edges. Do not move them constantly — let them develop a good char.

5. Transfer to a platter. Immediately dress with the remaining olive oil, lemon juice, red wine vinegar, oregano, garlic, salt, and pepper.

6. Let the octopus sit in the dressing for 5 minutes before serving. Scatter with parsley and serve with lemon wedges.

NOTES

- The no-water braising method is traditional and foolproof. The octopus cooks in its own juices, concentrating the flavor.
- Frozen octopus is often more tender than fresh because the freezing process breaks down the muscle fibers. Many Greek tavernas use frozen octopus for this reason.
- A cork thrown into the braising pot is an old Greek grandmother's trick said to tenderize the octopus. The science is debatable, but the tradition is non-negotiable.
- This is excellent at room temperature and can be prepared several hours ahead for a gathering.
