Grilled octopus isn’t just for restaurants — with a few straightforward steps you can prepare tender, flavorful octopus at home on your grill.
What is grilled octopus?
Octopus has a firm, meaty texture that becomes tender when cooked correctly and develops a pleasant char on the grill. It’s not fishy — the flavor is mild, similar to squid, and readily absorbs marinades and seasonings.
Grilling octopus is easier than many expect. This recipe uses a two-step approach: first simmering the octopus to tenderize it, then marinating and grilling to add char and depth of flavor.
Serve it over a fresh fennel salad, toss it into a warm vegetable stir-fry, or present it as an elegant appetizer. If you enjoy seafood or want to try something new, grilled octopus is worth a shot.
Grilled Octopus Salad
Ingredients
Grilled Octopus
- 1 fresh octopus (or pre-cooked tentacles)
- 1 large pot of water
- Juice of 1 orange
- Juice of 1 lemon
- Juice of 1 lime
- 1 1/2 tsp salt
- 1 tbsp whole peppercorns
- 1/2 cup white wine
- 1 wine cork (optional)
Citrus Vinaigrette
- Juice and zest of 1 orange
- Juice of 1 lemon
- Juice of 1 lime
- 1/2 cup olive oil
- 2 tbsp honey
- 2 tbsp white wine vinegar
- 1 clove garlic, minced
- 1/2 tsp salt
- Pinch red pepper flakes
Fennel Salad
- 1 fennel bulb, thinly sliced
- 2 tbsp fennel fronds, for garnish
Instructions
- Steam: Heat the pot of water over medium-high heat. Hold the octopus by the head and dip the tentacles into the water for about 10 seconds, lifting and redipping three times to encourage the tentacles to curl. Then fully submerge the octopus.
- Flavor Broth: Add the citrus juices, salt, peppercorns, white wine and the wine cork if using. Cover and simmer for 1 hour 15 minutes to 1 hour 30 minutes, until the tentacles are tender when pierced with a knife.
- Prep Salad: While the octopus cooks, whisk together the vinaigrette ingredients in a large bowl. Reserve 2 tablespoons of vinaigrette for finishing. Slice the fennel thinly and refrigerate until assembly.
- Marinate: When the octopus is tender, transfer to a cutting board. Remove and discard the head, cut off the tentacles, pat them dry, and place them in the vinaigrette to marinate for 30 minutes up to overnight.
- Grill: Heat the grill to high. Place the tentacles on the hot grill and cook, turning as needed, until charred on all sides.
- Assemble: Toss the fennel strips with the reserved vinaigrette and make a bed on each plate. Top with 2–3 pieces of grilled octopus, drizzle with remaining vinaigrette, and garnish with fennel fronds.
Notes
If fennel isn’t to your taste, substitute arugula, spinach, or frisée as the salad base.

Additional Info
Ingredients
You can prepare this dish two ways: cook a whole fresh octopus yourself, or use pre-steamed octopus tentacles for a faster approach.
- Octopus: Use a whole fresh octopus or pre-cooked tentacles.
- Steaming Liquid: For fresh octopus, flavor the simmering water with citrus, salt, peppercorns and white wine.
- Wine Cork: Unusual but traditional — some cooks add a wine cork to the simmering liquid to help tenderize the meat.
Salad Ingredients
- Fennel: A bulb with a mild licorice note used here thinly sliced as the salad base. Look for it near celery and root vegetables.
- Citrus Vinaigrette: Combines citrus juice and zest, olive oil, honey, white wine vinegar, garlic, salt and a pinch of red pepper flakes for balance.
Substitutions: Any leafy greens work well — arugula, spinach or frisée are great alternatives to fennel.

You must pre-cook octopus before grilling it
Raw octopus will be tough and chewy on the grill. Simmering, steaming, or pressure-cooking first ensures a tender result. If you buy pre-cooked tentacles, you can skip the simmering step and proceed directly to marinating and grilling.
If you want a bit of adventure, check local Asian markets for whole fresh octopus and follow the full cooking method below.
- STEP ONE: Fill a large pot with enough water to cover the octopus and bring to a simmer.
- STEP TWO: To create curled tentacles, hold the octopus by the head and dip the tentacles briefly into the hot water three times before fully submerging it. The heat will cause the tentacles to curl.
- STEP THREE: Once the tentacles are curled, add the orange, lemon and lime juices, salt, whole peppercorns and white wine to the pot. Simmer gently to infuse the octopus with flavor.
PRO TIP: Citrus adds sweetness and brightness; you can also add onion, garlic cloves, or bay leaves for additional depth.
PRO TIP: Adding a wine cork to the simmering liquid is an old cook’s trick said to help tenderize the meat.
- STEP FOUR: Cover, reduce heat to a gentle simmer, and cook about 1 1/2 hours. The octopus is done when tender to a fork or sharp knife.
How to grill octopus
Grilling is used mainly to develop texture and char since the octopus is already cooked. You can grill immediately or refrigerate and grill later. The vinaigrette’s oil helps achieve a beautiful sear.
Use a charcoal, gas, or pellet grill set to high direct heat (around 400°F), or a hot grill pan if you don’t have an outdoor grill. Cook the tentacles, turning occasionally, until charred and crisped to your liking.
- STEP ONE: While the octopus cooks, whisk vinaigrette ingredients and refrigerate. Thinly slice the fennel and reserve fronds for garnish.
- STEP TWO: Pat tentacles dry, then marinate them in the vinaigrette for 30 minutes to overnight.
- STEP THREE: Grill over high heat until charred on all sides.
How to serve grilled octopus
Serve grilled octopus several ways. A favorite is a fennel salad: toss the fennel with reserved vinaigrette, mound it on a plate, place charred tentacles on top, drizzle with remaining dressing, and finish with fennel fronds.
Other options include tossing grilled octopus with butter, capers, lemon juice, and fresh herbs such as thyme, oregano, or tarragon.
Storage
Store leftover grilled octopus in an airtight container in the refrigerator for up to 3 days, or freeze for up to 9 months.
