Instructions

  1. Step 1: In a large pot, combine 6 cups water, 1/4 cup white wine vinegar, 1 tsp salt, and 1 tsp dried oregano. Bring to a boil over high heat.
  2. Step 2: Add 2 lbs whole cleaned octopus to boiling water. Lower heat to medium and simmer gently, covered, for 45 minutes until tender when pierced with a fork. Remove octopus and let cool.
  3. Step 3: Once cool enough to handle, cut octopus into 2-inch pieces. In a bowl, toss with 4 tbsp lemon juice, 2 tbsp olive oil, 2 minced garlic cloves, 1 tsp dried oregano, 1/2 tsp salt, and 1/2 tsp black pepper. Marinate for 30 minutes at room temperature.
  4. Step 4: Preheat grill to medium-high heat. Thread octopus pieces onto skewers or place directly on grill grates. Grill for 3-4 minutes per side until charred edges appear and octopus is heated through.
  5. Step 5: Transfer grilled octopus to a serving platter. Drizzle with remaining 2 tbsp olive oil, scatter 2 tbsp drained capers and 1 minced garlic clove over the top, and sprinkle 2 tbsp chopped fresh parsley.
  6. Step 6: Serve immediately with lemon wedges if desired.
