In summary: Yes, cooked octopus can be frozen for 3 months without significant loss of texture. Best in its own juices or covered with EVOO. Thaw 24h in the refrigerator (NEVER at room temperature). Reheat gently to maintain texture.

Yes, you can freeze it — and do it well
Cooked octopus RETAINS texture after freezing if done correctly. It's a food with a high collagen content (transformed into gelatin when cooked), and freezing preserves that structure as long as no violent thermal shock is applied.
Raw octopus, on the other hand, is almost always frozen for 48-72h BEFORE cooking to break down fibers (traditional Galician technique). Cooked octopus is frozen AFTER for preservation.
How to freeze cooked octopus correctly
Method 1 (best): vacuum-sealed with its own juice. If you have a vacuum sealer, use a vacuum bag with octopus + 30-50ml of its juice. Remove air. Freeze.
Method 2: Tupperware with EVOO. Airtight Tupperware, octopus covered with EVOO, freeze. The oil prevents ice crystals on the surface.
Method 3: Zip-lock bag + cling film. Wrap octopus in cling film, then place in a well-sealed zip-lock bag. Less optimal but valid.
DO NOT: freeze dry octopus (without liquid). Air creates crystals that damage the texture.
How to thaw WITHOUT spoiling texture
Correct method: 24h in the refrigerator. Move from freezer to fridge 24h before use. Slow thawing preserves texture.
Quick method (not ideal but valid): immerse the sealed bag in COLD water for 1-2h. Change water halfway through.
NEVER do: thaw at room temperature (bacterial risk), in hot water (cooks the octopus), in the microwave (rubbery texture).
Actual duration: 3 months with quality
Cooked octopus frozen correctly lasts 3 months with maximum organoleptic quality. Up to 6 months with acceptable quality but will lose some flavor and aroma.
Label the bag with the freezing date. After 3 months, use in stews or cooked dishes (where the difference is less noticeable) instead of "a la gallega" (where octopus is the main ingredient).

To conclude
Freezing cooked octopus is perfectly viable and useful if you buy in bulk for several meals. The key is the method: vacuum-sealed with juice, slow thawing for 24h in the refrigerator, gentle reheating. Quality Galician cooked octopus withstands freezing well; generic octopus loses more when frozen.
