Grilled octopus is a staple in Greek cuisine, known for its smoky flavor, tender texture, and simple yet flavorful seasoning. Whether served as a meze (appetizer) with a drizzle of olive oil and lemon juice or as a main dish paired with classic Mediterranean sides, Greek-style grilled octopus is a true delicacy.
Many home cooks shy away from cooking octopus, fearing it will turn out rubbery or tough. The secret to achieving a tender yet charred and crispy texture lies in proper preparation. This article will guide you through the process, from selecting the best octopus to marinating and grilling it to perfection.
Step 1: Selecting and Preparing the Octopus
Choosing the Right Octopus
When shopping for octopus, you have two primary choices: fresh or frozen. While fresh octopus may seem like the best option, frozen octopus actually has an advantage. Freezing breaks down some of the tough fibers, making it naturally more tender once cooked.
A whole octopus typically ranges from 2 to 4 pounds. For grilling, a medium-sized octopus (around 3 pounds) is ideal, as it cooks evenly and remains tender.
Cleaning the Octopus
If your octopus has not been cleaned, you’ll need to remove the beak and innards:
- Rinse the octopus under cold running water.
- Turn the head inside out and remove any internal organs.
- Remove the beak, which is located at the center where the tentacles meet.
- Rinse thoroughly to remove any excess slime or debris.
Step 2: Pre-Cooking for Tenderness
Since octopus is naturally tough, pre-cooking is necessary before grilling. Greek chefs often simmer octopus in water infused with aromatics to ensure tenderness.
How to Boil the Octopus
- Fill a large pot with water and add aromatics such as bay leaves, garlic, onion, and red wine vinegar.
- Bring the water to a gentle simmer (do not boil vigorously, as it can make the octopus tough).
- Submerge the octopus and cook for 45–60 minutes, depending on size. It’s ready when a fork easily pierces the thickest part of the tentacle.
- Remove from water and let it cool to room temperature before grilling. This step also helps dry out the skin, allowing it to crisp up beautifully on the grill.

Step 3: Marinating the Octopus
Once cooled, the octopus benefits from a marinade to enhance its flavor. Traditional Greek marinades are simple yet effective, allowing the natural taste of the octopus to shine.
Greek-Style Marinade
- 1/4 cup extra virgin olive oil
- Juice of 1 lemon
- 2 cloves garlic, minced
- 1 teaspoon dried oregano
- 2 tablespoons red wine vinegar
- Salt and black pepper to taste
Marination Process
- Cut the octopus into manageable sections, usually separating the tentacles.
- Mix all marinade ingredients in a bowl.
- Coat the octopus pieces in the marinade, ensuring they are well covered.
- Let it marinate for at least 30 minutes, but for best results, refrigerate it for up to 4 hours.
Step 4: Grilling the Octopus
Grilling adds the signature charred edges and smoky depth that make Greek-style octopus irresistible.
Grilling Instructions
- Preheat the Grill: Heat your grill to medium-high heat (about 400°F). If using charcoal, let the coals turn white-hot before placing the octopus on the grate.
- Brush with Olive Oil: Before grilling, brush the octopus with extra olive oil to prevent sticking.
- Grill the Octopus: Place the tentacles directly on the grill and cook for 2–3 minutes per side until slightly crispy with charred grill marks.
- Avoid Overcooking: Since the octopus is already pre-cooked, grilling is just for flavor and texture. Do not leave it on the grill too long, or it will dry out.
Step 5: Serving the Grilled Octopus
Once grilled to perfection, it’s time to plate the octopus in true Greek fashion.
How to Serve Greek-Style Grilled Octopus
- Slice the tentacles into bite-sized pieces.
- Drizzle with extra virgin olive oil and fresh lemon juice.
- Sprinkle with sea salt, cracked black pepper, and fresh parsley.
- Optionally, garnish with capers or olives for extra Mediterranean flair.
- Serve alongside roasted potatoes, Greek salad, or crusty bread to complete the meal.
Additional Tips for Perfect Greek-Style Grilled Octopus
- Use a Hot Grill: A properly preheated grill ensures a good sear without overcooking.
- Don’t Skip Pre-Cooking: Skipping the boiling step results in tough, chewy octopus.
- Marinate for Maximum Flavor: Longer marination enhances the taste, but even 30 minutes can make a difference.
- Pair with the Right Drink: A glass of chilled ouzo or a crisp Greek white wine (Assyrtiko) complements the dish beautifully.
