Tender grilled octopus with bright Mediterranean flavors of lemon, garlic, oregano, and olive oil, first simmered until tender then quickly charred for crispy edges. Make-ahead friendly and perfect for a relaxed seafood dinner.
Keep the simmer gentle to avoid toughness. Save the cooking liquid for soups, rice, or beans. Octopus can be cooked ahead and chilled in the marinade up to 24 hours. Without a grill, use a hot grill pan or cast-iron skillet and sear 2 to 3 minutes per side. Refrigerate leftovers up to 3 days or freeze up to 2 months; re-grill briefly to reheat. Plan 6 to 8 ounces cooked octopus per person as a main.
