Step 1: Prepare the Octopus
Cooking the Octopus: In a large pot, bring salted water to a boil. If using fresh octopus, you can clean it by removing the head and insides. Frozen octopus is often pre-cleaned. Add the octopus to the boiling water and cook for about 30-45 minutes until tender. Check for doneness by piercing the thickest part with a fork. It should be soft but not falling apart.
Cooling: Once cooked, remove the octopus from the pot and let it cool in a bowl.
Step 2: Prepare the Salad Ingredients
Chop the Vegetables: While the octopus cools, prepare the other ingredients. Chop the red onion, celery, and parsley, and halve the cherry tomatoes.
Slice the Octopus: Once the octopus is cool, slice it into bite-sized pieces. You can choose to include the tentacles for a beautiful presentation.
Step 3: Mix the Salad
Combine Ingredients: In a large mixing bowl, combine the chopped octopus, red onion, celery, cherry tomatoes, parsley, and olives.
Dress the Salad: In a separate bowl, whisk together the lemon juice, lemon zest, olive oil, salt, and pepper. Pour the dressing over the salad mixture and toss gently to coat everything evenly.
Step 4: Marinate
Let It Sit: For the best flavor, let the salad marinate for at least 30 minutes in the refrigerator. This allows the flavors to meld together beautifully.
