Tender baby octopus is gently braised, marinated overnight with lemon and olive oil, then seared until the edges turn golden and crisp. It is a bright, savory seafood dish that works beautifully as a starter, shared plate, or grilled main with crusty bread.
Make the braising liquid: add the water, onion, garlic, peppercorns, salt, lemon juice, parsley stems, and bay leaves to a large pot. Bring to a boil over high heat.
Add the baby octopus and return the liquid to a boil. Reduce the heat to very low so the liquid barely simmers, then skim off any foam that rises to the surface.
Braise for 45 minutes, then test a piece for tenderness. Continue cooking for up to 1 hour total, or until the octopus is tender but not falling apart.
Drain the octopus well in a colander. Discard the onion, bay leaves, parsley stems, and other braising aromatics, then transfer the hot octopus to a large bowl.
Mix the olive oil, lemon zest, chilli flakes, salt, and black pepper in a small bowl. Pour over the hot octopus and toss thoroughly so it absorbs the marinade as it cools.
Let the octopus cool completely, then cover and refrigerate overnight. Before cooking, bring it out of the fridge for 20-30 minutes so it is not ice cold.
Heat a barbecue flat plate or large heavy skillet over medium-high heat. Add the canola oil, then lift the octopus from the marinade with tongs, leaving excess oil behind.
Sear the octopus for 3-5 minutes, turning as needed, until lightly charred and crisp around the tentacles. If using a skillet, cook in batches so the octopus browns instead of steaming.
Transfer to a serving plate. Finish with chopped parsley, sliced red chilli, and lemon wedges, then serve hot with bread, potatoes, or a simple salad.
Do not boil the octopus hard after adding it to the pot; a gentle simmer keeps it tender. Marinating while the octopus is still warm helps the lemon and olive oil flavor penetrate. For the best crust, drain off excess marinade and avoid crowding the pan. Leftovers can be refrigerated for up to 2 days and are excellent sliced into salads or served cold with extra lemon.
