This Instant Pot octopus is amazing! Cooked to perfection in 20 minutes, it tastes like a grilled octopus from a Greek restaurant! Cooking octopus has never been easier, thanks to the Instant Pot!
Put water, octopus and half of the lemon slices in the Instant Pot. Close the lid and turn the valve to a Sealing position. Press the "Pressure Cook" or "Manual" button and set the time to 15 minutes on High pressure.
When the Instant Pot is done cooking, quick release (QR) the steam, open the lid and drain the octopus.
Slice the octopus into strips, and while you are slicing it, cut off and discard the hard beak that's in the center of octopus body.
OPTIONAL STEP: put the octopus pieces on a baking sheet in a single layer and broil in a pre-heated oven for 3 minutes.
Put the octopus pieces in a serving dish, squeeze the remaining lemon slices over it, add olive oil and toss until combined.
