This delicious recipe for Poisson Cru à la Tahitienne is an easy appetizer featuring raw tuna marinated in fresh lime juice mixed with creamy coconut milk, cucumbers and tomatoes.
I first discovered this traditional French Polynesia dish while island-hopping through the South Pacific. I sampled versions of poisson cru — known as ia ota in Tahitian and Oka i’a in Samoa — in home kitchens and restaurants from Bora Bora to Tikehau and can say that this is the very best poisson cru recipe around!
Much like Latin ceviche and Spanish salpicón de mariscos (seafood salad), it takes just minutes to prepare!
My immersion into French Polynesian cuisine took place at a cooking class set on a tiny coral atoll near Tikehau, 350 km northeast of Tahiti.
The Tuamotu archipelago is dubbed Tahiti’s “strand of pearls” and is a string of 77 stunning islands and atolls strewn across the South Pacific.
Our base was the Tikehau Pearl Beach Resort, a luxury resort set on its own motu (tiny island) tucked within a wild coconut grove and surrounded by pink sand beaches.
“The lagoon surrounding this island is one of French Polynesia’s richest in marine life,” said Anne Tran-Thang, the resort’s general manager, as we walked across the wooden pathways suspended above the shallow blue waters.
Peering down, I could see brain coral as large as a submerged VW Beetle and a ring of brilliant Bénitier coral as bright as a sapphire necklace. And a lot of unusual marine life!
Donning a snorkel mask and armed with my Fujifilm FinePix XP80 Waterproof Digital Camera, I stepped into the crystalline waters and within minutes was welcomed by schools of sergeant majors, a bright blue parrotfish and a titan fish seemingly intent on lifting its head out of the water.
I later learned that titan fish can be quite territorial and aggressive but this one seemed ultra friendly.
A Poisson Cru à la Tahitienne Cooking Class
The next morning it was time for a private cooking class on an even more remote island. We travelled across the endless expanse of the Pacific to a speck of sand ringed by coral and dotted with spiky Pandanus shrubs.
Our local guide Chef Bachou Raufau toted the provisions to a shady spot and built a fire to grill the red snapper. While it grilled, he demonstrated how to handcraft serving trays out of palm.
“Weaving is still very much a tradition among the Mamas of our village,” he explained, as he deftly wove leaves into sturdy utensils.
Then we learned how to make Tahitian-style Poisson Cru a traditional dish of raw tuna marinated in lime juice and coconut milk that’s similar to Latin ceviche. Known as ia ota in Tahitian, it was the perfect recipe to learn as it’s considered the national dish of Tahiti and the islands of French Polynesia.
Is Poisson Cru Tahitienne a Fish Salad or a Ceviche?
Although I originally thought Poisson Cru was basically a Tahitian-version of ceviche, I quickly discovered that there are important differences.
To begin, unlike Latin ceviche, the vegetables are coarsely chopped rather than finely diced. Chunks of fresh seeded cucumber are mixed with chunks of fresh tomato rather than minced veggies you’d see in ceviche.
Poisson Cru is also different from Latin ceviche in the type of fish used. The best fish to use for Poisson Cru Tahitienne is tuna. A flaky fish will disintegrate and quickly turn mushy. Oily fish such as mackerel won’t provide the same delicate flavour.
“For us, shark, turtle and eel are sacred, so we don’t eat them, “ said Bachou our chef as he chopped a slab of tuna into chunks on his cutting board.
The fish is also marinated very briefly rather than marinated for a long period of time. The addition of coconut milk is also an important step in making Poisson Cru Tahitienne.
“To get the freshest miti haari or coconut milk, you grate a ripe coconut and then squeeze the milk out through a cloth,” he explained.
The Poisson Cru Tahitienne we made that day was velvety, with the tender cubes of tuna tasting as fresh as the sea. The coconut milk added a touch of sweetness while the crunch of cucumber and red tomato made it an especially memorable dish.
It was followed by grilled red snapper, a hearty main course with a smoky flavour and crispy skin, infused by the charcoal of the open fire.
We enjoyed it all at a table set in the shallow water’s edge where sleek lemon and black tip sharks glided past, hoping for a handout. The ever-fearless Sue Campbell took the video below of the dozens of sharks circling around our table.
I watched my table scraps get snapped up by a flurry of snapping jaws and decide to lift my toes out of the water; for while Polynesian tastes and traditions might preclude eating shark, the feeling might not be reciprocal.
Tips for Making French Ceviche or Tahitian E’ia Ota
Although this recipe for E’ia ota is very easy, there are a few tips and secrets to success when making any marinated raw fish recipe. For the best marinated fish Tahitian island style, here’s what you need to know:
- Select the highest quality raw tuna that you can afford. Sushi-grade tuna is your best choice. You may need to order it in advance from your fish monger.
- Look for tuna that appears moist but not soggy. It should have a fresh-from-the-sea smell with no fish odour.
- Tuna should be bright red and translucent with no browning.
- Fresh coconut milk is best but light canned coconut milk makes a good substitute. Be sure to stir the coconut cream throughly before using.
- This fresh ceviche should be prepared just before serving. The raw fish should be marinated in fresh lime juice for just a few minutes not hours. If the delicate raw tuna sits in lime juice for too long it can burn the flesh.

Thanks For Sharing this amazing recipe. My family loved it. I will be sharing this recipe with my friends. Hope the will like it.
Thank you for sharing what you learned! I would have been missing out on this great recipe! LOVE!
I love taking cooking classes when I travel, as well as learning about their traditional/signature dish. This fish ceviche looks so refreshing, good, and I can’t wait to picture myself eating this with Tahiti music in the background
Cooking classes really are a great way to pick up some new cooking skills and enjoy a fun lunch at the same time!
Love the fresh and delicious flavours of this dish!
This fish dish sounds so tasty and easy to make too!
This sounds so so yummy! And I usually make my ceviche with chunkier veggies so I think I will really like this!
I love taking a cooking class when I travel. Such a great way to learn about the culture. This recipe looks delish, and one i will try once the weather warms up. Something about eating ceviche with snow outside that really doesn’t work for me. What a gorgeous location-I think anything would taste pretty wonderful in French Polynesia.
Thank you for sharing it was delicious! We enjoyed this very much and it was super quick to make. If only we had fresh coconuts!!! Me and my husband ate this with almost every meal when we were in Bora Bora.
I’m happy to hear you enjoyed it Devon! I agree….it would be wonderful to have a coconut tree handy!
Michele, I am SO with you on this journey. Your photos are delightful, and I can just taste the ceviche. I’ve not yet been to Tahiti, but French Polynesia is definitely on my list!
Wow. Those islands are the definition of sea level—until sea level rises. I’m not a fan of raw fish, but I did enjoy some of the ceviche on our recent trip to Ecuador and Colombia and I’m a fan of the vegetables, so maybe I’d give this version a try. As for eating surrounded by agitated sharks—-nah, but the location sure looks beautiful, especially after a freezing day here in Philly.
