Grilled Octopus is Easy and Delicious

Grilled octopus | Something New For Dinner I fell in love with grilled octopus last summer when I was in Greece. We rented a boat with three couples and cruised the Saronic Gulf. It was a fabulous experience in so many ways, but we particularly enjoyed exploring the islands and finding new tavernas (small Greek restaurants) for dinner each night. Grilled octopus was always on the menu and I dare say we ordered it every night. Here is my seared octopus recipe so you can enjoy this Greek dish at home.

There is No Reason to Fear Octopus!

For most Americans, the idea of cooking octopus sounds challenging, unsettling and plain old scary. Fear not, cooking these cephalopods is not hard and makes for a fun group activity. This octopus recipe is almost foolproof if you follow my instructions. I provide two different ways to tenderize it; both work beautifully.

How to Buy Octopus

Grilled octopus | Something New For Dinner

Look for whole, frozen octopus. A good fishmonger can find one for you. I purchase mine at Santa Monica Seafoods in Costa Mesa, California. A whole Spanish octopus will typically weigh between 4 and 7 pounds. They are cleaned before frozen, but will include the head and the beak. (More on that later.) A 4 - 7 pound octopus sounds like enough to feed an army, but they shrink a lot. Once prepared it will provide an appetizer quantity for eight or dinner for four. These octopus are not inexpensive. Plan on spending $55 to $70 for one 4 - 7 pound octopus.

Prepping the Octopus

The good news is that most octopus you buy in the US will be frozen and cleaned. Thaw the octopus overnight in the fridge. Now comes the part where you need to get over your squeamishness. You need to remove the beak. Yep, the beak. It is the only hard part of this gelatinous creature. The beak is located inside the octopus mouth and is used to cut into its prey.

I start by cutting off the octopus' head, which is really just a thin, empty balloon-like sack. I've read the head can be eaten, but I have not done so yet. Lay out the octopus and cut the head off just above the beak.

I then use my knife to make the small hole where the beak was a little bit larger. Later I will use this hole to thread the end of a wooden spoon through so I can dip the octopus in a hot pot of water.

With the head removed, find the beak and push it through the flesh. It will literally pop out.

Curling the Tentacles

This step is a crowd pleaser. I use the Spanish method of cooking octopus that calls for dipping the octopus in the water three times. This may be a bit more tradition than science, but it does work and if you have an audience while you are cooking they will love this step.

Simply bring a pot of water to boil, thread the wooden spoon through the hole where the beak was and dip it in the water for a few seconds. Pull the octopus out of the pot and you will notice the tentacles have curled up nice and cute. Grilled octopus | Something New For Dinner Dip the octopus two more times.  Each time you dip it in the water the tentacles will curl up a bit more. Now your octopus is ready to tenderize.

Tenderizing Octopus Two Ways

No one wants to eat chewy octopus and there are a lot of ways to tenderize it. The good news is that if you are using previously frozen octopus, the tenderizing process has already begun. Tenderizing happens differently in different cultures. Grilled octopus | Something New For Dinner In Greece they hang the octopus in the sun to dry. As you stroll down the street you will see octopus hanging out in front of many tavernas. Other touted methods include beating it with a rock, cooking it in a copper pot or massaging it with a daikon radish as they do in Japan. The method I recommend is cooking it low and slow either by braising or cooking it sous vide. Both methods are included in the recipe below.

Sous Vide Method

The sous vide method results in extremely succulent and tender octopus. Prepping for sous vide takes just a few minutes, but it takes four hours in the sous vide bath. The good news is this is all hands-off time and the results are phenomenal.

Slow Braise Method

Braising also results in tender and delicious octopus. It requires a few more ingredients, but takes only about and hour and a half on the stove. The results are also very good.

Octopus Cooking Folklore

When it comes to cooking octopus there is a lot of folklore, here are three of my favorite:

1. Wine Corks to Tenderize

Many Mediterranean chefs, including Mario Batali, swear that putting a cork in the pot helps to tenderize it. Some call for a single cork and others a handful of corks. I have researched this and have found no compelling reason for it. It may just be a good excuse to open a bottle of wine or two.

2. Copper Pot or Copper Penny

Jose Andres says cooking octopus in copper results in a chemical reaction that turns the octopus a beautiful red. This can be accomplished by cooking the octopus in a copper pot or by throwing a few clean copper pennies in the broth. I have added pennies when I braised my octopus for fun and have used a copper pot to curl the tentacles of the octopus. I'm not sure it made a difference.

3. Dipping Three Times

Now this I do, but the purpose may be as much for drama when cooking for an audience as for actual purpose. The tentacles do curl each time you dip it, but it is possible they'd curl up if you just threw the octopus in the braising pot too. Definitely something to test.

To Remove the Skin or Not

When the octopus is done tenderizing, either by braising or cooking sous vide, the skin will be slimy and will easily come off when you touch it. Some cooks advocate removing the gelatinous skin completely, others are adamant that the gel is flavorful and should remain on. I take a middling approach and rinse off a good portion of it by rubbing it lightly under water or with a paper towel. One of these times I will leave it all on before I grill it and let you know what I think.

Grilling the Octopus to Finish

Grilled octopus | Something New For Dinner Once the octopus is tenderized it can be seared immediately or placed in the fridge for a day or two until you are ready to serve. The key to making a great grilled octopus is to dry it well before searing, just like beef, chicken or fish. If you leave moisture on the octopus it will not develop a good sear. You can sear octopus on the grill or in a grill pan on the stovetop.

What to Make with Grilled Octopus?

I like eating grilled octopus very simply like the Greeks do with a little olive oil, lemon and salt and pepper. You can add it to salads, serve it with a sauce or create a number of different dishes. For me, simple is best as I really enjoy the flavor of the octopus and don't want to confuse my taste buds by adding a lot of other stuff.

Health Benefits of Eating Octopus

Octopus provides great nutrition. It is very low in fat and high in protein. Three ounces of cooked octopus contains about 140 calories and 25 grams of protein. It is rich in B12, copper, selenium, iron, B-6 and omega-3's.

Ethics of Eating Octopus

When I learned how incredibly intelligent octopus are I became a little queasy about eating them. Then after doing some research, I also learned octopus are carnivores, and some are cannibals. Some female octopus actually eat their mate after sex. Not joking. So now I put all this information into perspective and consider it OK to eat octopus.

Grilled Octopus — Two Ways

5 from 1 review

Grilled octopus is surprisingly simple to make. The key is tenderizing the cephalopod before you grill. This recipe provides two methods: sous vide and braising. I walk you through the preparation step-by-step, including removing the beak, curling the tentacles and tenderizing. 

  • Yield: servings
  • Category: Dinner
  • Cuisine: New American



Braised method:

  • 1 4-7 pound frozen Spanish octopus
  • Olive oil
  • 23 lemons
  • 23 garlic cloves, peeled and lightly smashed
  • 1 onion, peeled and quartered
  • Fresh thyme or oregano
  • 45 whole peppercorns
  • 1 cup of wine

Sous vide method:

  • 1 4- 7 pound frozen Spanish octopus
  • Olive oil
  • 2 fresh lemons



Prep the octopus:

If you buy frozen Spanish octopus they will be cleaned and ready to cook with the exception that the head and beak still need to be removed. Thaw in the refrigerator overnight. Slice off the head and remove the beak as shown in the headnotes of this recipe.

To curl the tentacles:

Both the sous vide method and the braising method start with curling the tentacles. 

Bring a large pot of water to boil. Thread the handle of a wooden spoon through the hole where the beak was. Lift the octopus over the pot and dip it into the boiling water for about 10 seconds. Pull it out and repeat two more times. The tentacles will curl up a bit after each dip.

To tenderize by braising:

  1. Heat a large pot to medium high. Add a glug of olive oil. Slice a lemon in half and cook cut side down to brown. Add garlic, onion, herbs and cook for 3 – 4 minutes. 
  2. Deglaze with wine. Add about a quart of water and a pinch of kosher salt. Bring to a boil. Lower the octopus into the boiling water and reduce heat to low. The octopus should be just covered with water. Simmer for an hour and a half. 

Note: if you want to add a clean copper penny do so when you add the water. This traditional method is supposed to aid in tenderizing and also give the octopus a deep red color.

To tenderize by sous vide:

  1. Bring a sous vide water bath to 180 degrees F. Place the octopus with a splash of olive oil and a pinch of kosher salt in either a Ziplock baggie or a vacuum sealer bag. Remove the air and seal the bag using the displacement method if you are using a Ziplock bag or a vacuum sealer.
  2. Submerge the octopus bag in the water bath and sous vide for four hours. 


To sear:

  1. Remove the octopus from the braising pot or the sous vide bag, depending on which method you are using. The octopus will be covered with a gelatinous coating. Gently remove most of this by either rubbing with a paper towel or rinsing under the sink. Take care not to over remove this jelly and do not rub so hard you remove the suckers. The suckers will crisp up when you sear them and are delicious. 
  2. Thoroughly dry the octopus and brush with olive oil. Sear on a grill or in a cast iron pan for 2 -3 minutes on each side. Plate drizzle with good olive oil and squeezes of lemon.

    We have made this octopus for the second Thanksgiving. I am now (along with my kids) a Pescetarian, so turkey is really not cutting it anymore. Making octopus seems intimidating at first, but it is actually a very easy meal to prepare. There is also a bit of a “show” when you dip the octopus in the hot water to curl the tentacles. Preparing the octopus is such a blast and it a true conversation piece for the night. I followed the recipe “loosely” it seems to be a forgiving prep. Lastly, it is amazing how many guests had vowed they were not going to eat it when in actuality everyone tried it. Thanks for our new Thanksgiving tradition!

      Thank you for your comments Bruce. It really is a fun dish to make. And I agree, many people have difficulty with the concept until it comes off the grill. I like to watch people’s faces as they take their first bite. They frequently go from very apprehensive to true believers. : )
