Frozen octopus is a convenient way to enjoy this healthy and delicious seafood whenever you like. However, knowing how to cook it properly is key to achieving the best results while preserving its natural flavour and tender texture. In this guide, we’ll share simple tips and tricks to help you prepare octopus with confidence and enjoy a delicious, high-quality dish every time. Since frozen octopus is commonly available in local markets, we’ll focus on an easy cooking method using frozen octopus as the starting point.
How to defrost frozen octopus:
The best way to defrost raw frozen octopus is to remove it from the freezer 24 hours before cooking and allow it to thaw slowly in the refrigerator.
If you need to defrost the octopus more quickly, place it in a sealed, leak-proof bag and submerge it in cold water, changing the water every 30 minutes. Alternatively, you can thaw it under cold running water until fully defrosted.
Can you cook octopus without defrosting it?
Yes, it is possible to cook octopus directly from frozen, but thawing it beforehand is recommended for more even cooking. The thicker central portion takes longer to cook than the tips of the tentacles, so starting with frozen octopus may result in uneven cooking if the timing is not adjusted.
Steps to cook octopus:
- Bring a large pot of water to a boil. Ensure there is enough water to fully submerge the octopus.
- Once the water is boiling, dip the octopus into the water for 5 seconds, then remove it for another 5 seconds. Repeat this process three times before leaving the octopus fully submerged.
-
Allow the water to return to a boil, then reduce the heat to maintain a gentle simmer. A 4-pound (approximately 1.8 kg) octopus should cook for about 20–25 minutes, starting from when the water returns to a boil.
- Remove the pot from the heat, cover it with a lid, and let the octopus rest in the hot water for another 20–25 minutes.
-
After resting, check that the octopus is tender before removing it from the water.
How can you tell if the octopus is cooked?
Remove the octopus from the water and insert a toothpick into the thickest part near the head, where the tentacles are attached. If the toothpick slides in easily, the octopus is tender and ready. If it still feels firm, continue cooking and check again.
Practical tips to cook frozen octopus properly:
- Choose the right pot: Use a pot large enough to fully submerge the octopus in water, ensuring it cooks evenly. Once the water comes to a boil, reduce the heat to prevent it from bubbling over and maintain a gentle simmer.
- Cook the octopus without salt: One common mistake when cooking octopus is adding salt to the cooking water. For this method, cook the octopus in unsalted water and season it after cooking to better control the final flavour.
- Choose quality ingredients: Even the best cooking technique cannot compensate for poor-quality ingredients. When purchasing raw octopus, check its quality, texture, weight, and appearance. Read the product label carefully to understand its origin and handling information, and choose a product from a reliable supplier to ensure the best possible results.
Frequently asked questions about cooking octopus:
How do you cook raw frozen octopus?
Place the thawed octopus in a pot of boiling, unsalted water. Once the water returns to a boil, cook uncovered over medium heat for approximately 15 minutes for a 2-pound (900 g) octopus. Remove the pot from the heat, cover it with a lid, and let the octopus rest in the hot water for another 15–20 minutes.
To check if it is cooked, insert a toothpick into the thickest part of a tentacle. If it slides in easily, the octopus is tender and ready to use.
How long does octopus take to cook?
Cooking time depends on the size and weight of the octopus. As a general guide, a 2-pound (900 g) octopus takes approximately 15 minutes of cooking time, followed by 15–20 minutes of resting in the hot water. For every additional pound, allow another 3–5 minutes for both cooking and resting.
However, these timings are estimates. Always check the thickest part of the tentacle for tenderness before removing the octopus from the water.
Octopus is enjoyed around the world for its distinctive flavour, tender texture, and versatility. It is also a convenient ingredient to keep on hand when purchased frozen, making it easy to prepare a variety of delicious dishes for home cooking or restaurant menus.
