Grilled Octopus & Cucumber Salad
Serves: 6-8
Bear Hands (author): Let me sell you on this: Smoky, supple octopus meets crisp cucumber and sweet onion in a study of balance and restraint. Lightly seasoned with shoyu and enriched by the quiet brininess of hijiki, this dish will particularly delight admirers of tako su—offering familiar harmony with a more indulgent, fire-kissed edge.
Hubby Bear (eater): I’m actually not a big fan of octopus, but this dish is pretty good. I think the meaty chard-ness of the octopus mixed with the fresh, crunchy cucumber makes it something I can really enjoy.
What it is
Smoky, briny, cool, refreshing… if you like octopus, you will love this salad. Hubby Bear is actually not a big fan of octopus, but he will happily eat this dish!
This can be a main dish with a side of rice, but is a really fun side dish too.
🥒Cucumber Size
As you might know if you have read my Refreshing Cucumber Salad with Vinegar Dressing, we like thick slices of cucumber in our house—between 1/4” and 1/2” thick. It seems most people prefer thinner slices—if this is you, feel free to adjust to your taste. We love the taste of cucumbers and they make our tummies feel good. Hubby bear, who suffers from acid reflux, will eat a cucumber like a banana, just starting at one end and going until it’s gone. We love the freshness and the crunch. If you don’t relate to this, just slice them a little thinner and I’m sure you will be on board.
🔥Charring the octopus
The charred flavor is the star of this dish.
I buy pre cooked octopus legs from my local H-Mart. This would be my recommendation as you only have to give it a char! That’s right, we’re not cleaning, cooking or seasoning!
If you are starting with a raw octopus, you’ll want to boil it first. It’s not a difficult process, are there are many short videos on YouTube that will explain it to you in under a minute.
But as a busy cat dad, I’m going to simply buy the cooked octopus and put some flame to it until you get the chard-ness you like. Here are two options:
Grill - Whether it’s charcoal, propane or other, get that thing going, oil the grate (octopus meat like to cling to the grill), and just get some nice color on it until you get the doneness you like.
Propane torch - I know some people just shuddered, “I don’t want my food tasting like gas!”. If this is you, go with the grill method. But I personally don’t have this issue, and using a torch is fun! I don’t get to use this kitchen insturment a lot, and I like the methodic process of slowly running the flame back forth and watching the magic happen. Let me enjoy my cooking damnit! 😂
🧅Onion
These play a important, background part so slicing them as thin as possible is idea. I like to use my mandoline slicer.
Enjoy!
This salad will hold up all week. Especially if you followed my suggestion to keep the cucumbers THICK.
Detailed recipe:

2-Grilled Octopus & Cucumber Salad
Ingredients
Instructions
Easy-follow Recipe:
Step 1: 🌊 Rehydrate Hijiki
2 tbsp dried hijiki seaweed – rehydrated, drained
- Place hijiki in cool water and soak for about 20 minutes (it will expand up to 4× its size).
- Drain thoroughly and then gently squeeze out excess water; texture should be supple, not soggy.
- Set aside.
Step 2: 🔥 Grill the Octopus
2½ lbs octopus legs – cut into thick bite-sized pieces
- Char octopus on grill or with propane torch to your desired color.
- Rest briefly (at least 5 minutes) to allow juices to redistribute for maximum tenderness and juiciness.
- Slice into bite-sized pieces: thinner slices at thicker parts, thicker slices toward the ends. The tips of the legs will form aesthetically pleasing bite-sized chunks.
- Set aside.
Step 3: 🥒 Slice Vegetables
3 medium cucumbers – thick slices
1 medium sweet onion – paper-thin slices
- Slice cucumbers thick (¼–½ inch) for crunch and structure.
- Slice onion as thinly as possible (mandoline recommended).
