Octopus (polipo or polpo in Italian) is delightful when it is cooked properly—tender and buttery soft—and it is wonderful in summer seafood salads such as octopus and potato salad (insalata di polpo e patate) or simply grilled with lemon. But it can be devilish to cook, going from tender to rubbery and back as it sits in the pot. 

In any case, don't be intimidated by cooking octopus at home—it's much simpler than you think and doesn't require any special tricks or equipment.


  • 2 to 3 pounds octopus (fresh or frozen)

Steps to Make It

  1. All frozen octopus is precleaned, and if buying fresh, you can ask the fishmonger to clean it for you. However, if the octopus is not precleaned, wash and clean it, removing the ink sac and internal organs by making a circular cut around the beak with a paring knife. Pull away the beak (the organs will come with it).

  2. Set the octopus in a large pot with enough water to cover, then bring the water to just a simmer.

  3. Simmer very gently at 190 to 200 F. Timing varies depending on the weight of the octopus and how many you are cooking. For 2 to 3 pounds of octopus (4 servings), it will usually be between 1 to 2 hours, but the true test for doneness is when a knife inserted where the head meets the legs slides in easily.

  4. Once the octopus is tender, you can serve it in a salad or mixed into a pasta or risotto. You can also grill it quickly over a high flame to crisp up the exterior.


    • Italian kitchen wisdom says to boil the octopus with a wine cork in the simmering liquid to keep it tender, but that is apparently nothing more than an old wive's tale, unsupported by science and multiple tests.
    • Other nations offer their own homegrown advice. Apparently, Greeks traditionally gave the octopus a few good whacks against some rocks, while Spaniards might insist on using a copper pot.
    • According to food science guru Harold McGee, the key to tender and flavorful octopus is instead blanching it for 30 seconds in boiling water and then baking it, covered, in an oven at 200 F for a few hours. It does make sense that, undiluted by cooking water, the octopus would retain more of its flavor. But if you don't have 4 to 5 hours to spare for this method, then you can just keep the cooking time minimal—less than 5 minutes—for a slightly chewy but still tender texture.
    • If you do have the time, use the long, slow cooking method (a gentle braise over low heat) for maximum tenderness. Slow braising in a liquid will take anywhere from about 1 to 2 hours, depending on how many pounds of octopus you are cooking.
    • Another secret to tenderness is that previously frozen octopus grows tender more quickly than fresh. It might seem counterintuitive because freezing can have a negative effect on both texture and flavor with many types of meat and seafood, but with octopus and squid, that is not the case. And you can use either fresh or frozen (which is usually much easier to find).
    • When buying fresh octopus, it should not have any fishy smell at all—if it does, that means it has already started to go bad.
