At Asador.mx, we believe the grill belongs to everyone — not just beef lovers. Grilled octopus with chimichurri is one of those dishes that proves Argentine-style live-fire cooking can elevate seafood to extraordinary heights. Tender, smoky tentacles charred to perfection over high heat, finished with that iconic green chimichurri sauce — this is Argentine BBQ at its most exciting and unexpected. Whether you are hosting a full asado or just want to explore beyond the traditional cuts, this recipe belongs in every griller's repertoire.

Why Octopus Works So Well on the Grill

Octopus is one of the most rewarding proteins you can throw on the parrilla. Its dense, meaty texture holds up beautifully to direct high heat, developing a gloriously caramelized crust while staying tender inside — provided you nail the pre-cooking step. Raw octopus grilled directly will be rubbery and tough, but octopus that has been gently simmered first transforms into something extraordinary the moment it hits those hot grates. The slight smokiness from the charcoal or wood fire pairs naturally with the briny, subtly sweet flavor of the cephalopod, and that combination with a sharp, herbaceous chimichurri is nothing short of addictive. In coastal Argentina, particularly in Buenos Aires and Mar del Plata, grilled octopus has earned a permanent place on the menus of the best parrillas and seafood restaurants alike. It is a dish that bridges the traditions of the sea and the open fire.

The Secret to Perfectly Tender Octopus

The most common mistake home cooks make with octopus is skipping or rushing the boiling stage. Octopus muscle is packed with collagen, and it takes sustained, gentle heat over time to break it down into that silky, yielding tenderness we are after. Do not be tempted to blast it at a rolling boil — a steady, calm simmer is your best friend here. Depending on the size of your octopus, this can take anywhere from 45 minutes to over an hour. The best test is simple: insert a thin knife or skewer into the thickest part of a tentacle. If it slides in with very little resistance, like a fork into ripe avocado, you are ready. Another trick passed down through generations of Argentine cooks is the three-dip method: before fully submerging the octopus, dip it quickly into the boiling water three times. This sudden heat causes the tentacles to contract and curl into those beautiful tight spirals that look so impressive on the plate. It also helps the outer skin set quickly, which preserves more of its texture during the long simmer that follows.

Mastering Chimichurri for Seafood

Traditional Argentine chimichurri was born alongside beef, but do not let that limit your thinking. The bright acidity of red wine vinegar and the fresh punch of flat-leaf parsley cut beautifully through the richness of grilled octopus, acting almost like a vinaigrette that awakens every bite. For seafood chimichurri, we keep the recipe fairly classic but lean into freshness over heat — less red pepper flake and more emphasis on good-quality olive oil and perfectly minced garlic. One key tip: give your chimichurri time to rest before serving. Even 15 to 20 minutes at room temperature allows the garlic and vinegar to mellow slightly while the parsley releases its aromatic oils into the sauce. If you can make it the night before, even better. Stored in the refrigerator in a sealed jar, chimichurri improves dramatically overnight as all those flavors deepen and meld. Just remember to bring it back to room temperature before serving — cold chimichurri over hot octopus dulls both elements.

Grill Setup and Pro Tips for the Perfect Char

Getting the right char on grilled octopus requires a very hot grill and the confidence to leave the octopus alone once it hits the grates. Resist the urge to move it constantly. Let the grill do its work for a full three to four minutes before attempting to flip. You will know it is ready to turn when it releases naturally from the grate without sticking — if it resists, it needs another minute. We recommend a two-zone fire setup when using charcoal: a hot zone for searing and a cooler zone for any pieces that are charring too quickly before cooking through. A light brush of olive oil on the octopus just before grilling is essential both for flavor and to prevent sticking. Do not skip drying the octopus with paper towels before oiling and grilling — surface moisture is the enemy of a good crust. Finally, when serving, be generous with the chimichurri. Spoon it directly over the hot octopus so the heat releases the aromatics of the sauce, and always have extra at the table along with cold lemon wedges. A great Argentine griller always leaves guests wanting more of the sauce.

This grilled octopus with chimichurri recipe is proof that the parrilla is a place of endless possibility.

Grilled Octopus with Chimichurri

Prep 30 min
Cook 1 hr 15 min
Total 1 hr 45 min
Yield 4 servings

Ingredients

  • 1 whole octopus, about 2 kg (4.4 lbs), cleaned
  • 1 cup fresh flat-leaf parsley, finely chopped
  • 4 cloves garlic, minced
  • 1/2 cup extra virgin olive oil, plus extra for grilling
  • 3 tablespoons red wine vinegar
  • 1 teaspoon dried oregano
  • 1/2 teaspoon red pepper flakes
  • 1 teaspoon coarse sea salt, plus more to taste
  • 1/2 teaspoon freshly ground black pepper
  • 1 lemon, cut into wedges for serving
  • 1 bay leaf
  • 1/2 white onion

Instructions

  1. Boil the Octopus

    Fill a large pot with water and bring it to a boil. Add the bay leaf, half white onion, and a generous pinch of salt. Using tongs, dip the octopus into the boiling water three times before fully submerging it — this helps the tentacles curl beautifully. Reduce heat to a gentle simmer and cook for 45 to 60 minutes, or until a knife slides easily into the thickest part of the tentacles. The octopus should be tender but not falling apart.

  2. Rest and Cool the Octopus

    Remove the octopus from the pot and let it rest on a cutting board or tray for at least 15 minutes. This resting period allows the juices to redistribute and the skin to firm up slightly, which will help it hold together better on the grill. Once cooled enough to handle, pat the octopus dry with paper towels to encourage a good char on the grill.

  3. Prepare the Chimichurri

    While the octopus rests, make the chimichurri. In a bowl, combine the finely chopped parsley, minced garlic, red wine vinegar, oregano, and red pepper flakes. Slowly whisk in the olive oil until the sauce is well combined. Season generously with salt and black pepper. Let the chimichurri rest at room temperature for at least 15 minutes so the flavors can meld together. This sauce can be made up to 24 hours in advance for even deeper flavor.

  4. Prepare the Grill

    Preheat your grill to high heat, aiming for around 230–260°C (450–500°F). If using charcoal, create a two-zone fire with a hot zone and a cooler zone. Brush the grill grates thoroughly with a wire brush, then oil them using a folded paper towel dipped in olive oil held with tongs. A clean, well-oiled grill is essential to prevent sticking and achieve beautiful grill marks.

  5. Grill the Octopus

    Cut the octopus into individual tentacles and separate the head into two or three large pieces. Brush each piece generously with olive oil and season lightly with salt and pepper. Place the octopus pieces on the hot zone of the grill. Cook for 3 to 4 minutes per side without moving them, allowing each side to develop deep char marks and a slightly crispy exterior. The total grilling time should be about 6 to 8 minutes.

  6. Serve with Chimichurri

    Transfer the grilled octopus to a serving platter and immediately spoon a generous amount of chimichurri over the top. Serve the remaining chimichurri on the side along with lemon wedges. Enjoy immediately while the octopus is hot and the crust is at its most satisfying.
