Instructions

  1. Step 1: In a large pot, bring 4 cups water to a boil. Add 2 lbs cleaned octopus and simmer gently for 45 minutes until tender when pierced with a fork. Drain and let cool slightly.
  2. Step 2: In a bowl, whisk together 1/4 cup olive oil, 1/4 cup fresh lemon juice, 4 minced garlic cloves, 2 tbsp chopped fresh oregano, 1 1/2 tsp salt, and 1 tsp black pepper to make the marinade.
  3. Step 3: Cut the cooked octopus into 2-inch pieces and toss thoroughly in the marinade. Cover and refrigerate for at least 1 hour to absorb the flavors.
  4. Step 4: Preheat grill to medium-high heat (about 400°F). Thread the octopus pieces onto skewers and grill for 3-4 minutes per side until edges are slightly charred and fragrant.
  5. Step 5: Remove from grill, arrange on a serving platter, and drizzle with any remaining marinade. Serve immediately with fresh lemon wedges for squeezing.
