Last month, I was planning a small dinner for friends but didn’t want to spend the whole afternoon cooking. I spotted a pack of octopus at Costco, and out of curiosity, I decided to give it a try. To my surprise, it turned out amazing — juicy, perfectly cooked, and full of flavor. It takes advantage of Costco’s pre-cooked octopus, which is tender, high-quality, and perfect for quick weeknight meals or elegant weekend dinners. This Mediterranean-inspired recipe combines olive oil, lemon juice, garlic, and smoked paprika to create a savory dish that tastes like it came straight from a seaside restaurant.
I have made this recipe several times since then, experimenting with different herbs and sides. I use a generous amount of olive oil and always fresh lemon juice — never bottled. Fresh garlic is a must for that deep, aromatic flavor. Every time I cook this dish, it reminds me how effortless fine dining can be at home.
You can serve it with roasted vegetables, some garlic mashed potatoes, also with buttered rice or a light green salad tossed in vinaigrette. It’s incredibly versatile — elegant enough for dinner parties yet simple enough for a weeknight meal.

How to Make Costco Octopus
Step 1
Prepare the octopus: Remove the pre-cooked Costco octopus from its packaging and rinse it gently under cold water to remove any excess brine. Pat dry with paper towels. If the tentacles are large, slice them into smaller, manageable portions for even cooking and easier serving.
Step 2
Infuse the oil with flavor: In a large skillet or grill pan, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1–2 minutes until it turns golden and fragrant — be careful not to burn it. This step infuses the oil with a rich aroma that will soak into the octopus later.
Step 3
Sear the octopus: Add the octopus pieces to the hot pan in a single layer. Let them sear undisturbed for about 3–4 minutes on each side, or until the edges begin to caramelize and turn slightly crisp. The goal is to get a nice golden-brown exterior while keeping the inside tender.
Step 4
Add seasonings: Sprinkle the smoked paprika, oregano, chili flakes (if using), and a pinch of salt and pepper over the octopus. Stir well to coat evenly in the oil and spices. Cook for another 2–3 minutes so the seasonings blend with the natural flavor of the seafood.
Step 5
Finish with lemon: Drizzle lemon juice over the hot octopus and toss gently to balance the smoky and savory flavors with a hint of brightness. Taste and adjust the seasoning if necessary.
Step 6
Serve and garnish: Transfer the octopus to a serving platter. Garnish with freshly chopped parsley and a few lemon wedges on the side for squeezing.
Tips for the Perfect Costco Octopus
- Pat dry before cooking. The drier the octopus, the better the sear. Extra moisture prevents browning, so always blot with paper towels.
- Cook in batches if needed. Too much octopus in one pan will steam instead of crisping. Give each piece space to caramelize.
- Use a heavy pan. A cast-iron or grill pan holds heat evenly and gives the tentacles that lovely charred edge.
- Let garlic infuse first. Sauté garlic in olive oil for 1–2 minutes before adding octopus. It gives a deeper, aromatic base flavor.
- Finish with lemon and herbs. Add lemon juice and fresh parsley at the end to keep the flavor bright and fresh.
- Avoid overcooking. The octopus is already pre-cooked — you only need to sear it for texture and warmth.
- Add a touch of spice. A pinch of chili flakes or smoked paprika gives a beautiful contrast to the mild, ocean flavor.
Optional Ingredients
- White wine (for deglazing the pan)
- Capers for a salty Mediterranean touch
- Butter for a silky, rich flavor
- Lemon zest for brightness
- Fresh chili or cayenne for spice
- Crumbled feta or parmesan for a creamy finish
How to Serve Costco Octopus
I love serving this dish right out of the skillet, hot and glistening with olive oil and lemon. The tentacles get slightly crisp on the edges, and that smoky aroma fills the air. I usually lay them out on a large platter, drizzle extra olive oil on top, and sprinkle a handful of chopped parsley for a restaurant-style presentation.
When I want a heartier meal, I serve the octopus over a bed of roasted potatoes or a simple lemon garlic pasta. The buttery, citrusy flavors soak up the juices perfectly. You can even serve it on top of risotto or creamy polenta if you’re in the mood for comfort food.
For parties or family-style dinners, I like to slice the tentacles into bite-sized pieces and arrange them with grilled vegetables, olives, and toasted bread. It becomes an instant Mediterranean platter everyone loves. Sometimes, I even add a small bowl of aioli or lemon garlic sauce for dipping — it elevates the dish without much effort.
Is Costco Octopus Healthy?
Yes! Costco octopus is packed with lean protein, low in calories, and contains healthy minerals like zinc, iron, and selenium. It’s also a great source of vitamin B12, which helps with energy and brain function.
Because this recipe uses olive oil, lemon, and spices instead of heavy sauces, it’s a nutritious, light meal option. You can enjoy it guilt-free while still feeling full and satisfied.

How to Store and Reheat
To store leftovers, let the octopus cool completely before transferring it into an airtight container. Keep it in the refrigerator for up to 2 days. Add a drizzle of olive oil before sealing to keep it moist.
To reheat, warm it in a skillet over medium heat with a small amount of olive oil for 2–3 minutes. Avoid the microwave, as it can make the texture rubbery. If using leftovers for salads or cold dishes, you can serve it straight from the fridge without reheating.
