Whenever I see ceviche on the menu in a restaurant, I almost always order it. Refreshing, light, and somewhat spicy, it’s a delicious appetizer. While there are endless varieties of ceviche, I recently discovered my favorite version during a trip to Puerto Vallarta, Mexico. It should come to no surprise to those who have been following me a while that I decided to recreate it when I got home! My Fresh and Flavorful Ahi Tuna Ceviche can be made in no time, and is a great party app or seafood snack for date night.


  • Ahi tuna: When making ceviche, you’ll want to make sure your fish is as fresh as possible, and you want to look for sushi grade tuna, like an ahi tuna steak.
  • Avocado: Creamy and mild in flavor, it also adds more protein and many other nutrients to the dish.
  • Lime: Not only does it add bright acidity, but the lime juice is an essential part to any ceviche as that acidity also helps to “cook” the tuna. You’ll want to make sure to use fresh lime juice for this dish.
  • Red onion: Mild enough to be eaten raw, the red onion adds some texture as well as a bit of spice to the ceviche.
  • Cilantro: Fresh and somewhat citrusy in taste, it also adds some color to the dish. If you happen to be one of those people who think cilantro tastes like soap, you could also use fresh parsley.
  • Salt: Seasons and enhances the natural flavors of the other ingredients.

How to Make Fresh and Flavorful Ahi Tuna Ceviche

Mincing an onion

Start your fresh and flavorful ahi tuna ceviche by dicing and mincing your produce. Because this appetizer is usually eaten as a dip or in small bites, you want to cut the ingredients fairly small as well.

Then you’ll take your ahi tuna steak and cut it into small cubes. Make sure to use a sharp knife, as the tuna meat is tender and can be smashed easily.

Adding tuna to bowl

Once cut, you’ll add the ahi tuna to a large bowl.

Then sprinkle with some kosher salt.

Adding lime juice to bowl

And add fresh lime juice over the top.

Adding diced avocado to bowl

Then you’ll add the red onion and the avocado.

Followed by the cilantro. If you like an extra kick of heat, this is where I’ll also add a minced jalapeño or a serrano pepper.

Stirring ceviche all together

Stir it all together, being gentle as to keep the avocado pieces in tact and not totally mashed up.

Let sit for about 20 minutes or so before serving for the lime juice to do it’s thing, and then enjoy your Fresh and Flavorful Ahi Tuna Ceviche alongside a plate of tortilla chips! Make sure to use corn tortilla chips if you want to keep the dish gluten-free.

Shake It Up

  • Up the citrus. If you want a bigger citrus flavor, you could also add lime zest or lemon juice to the ceviche.
  • Switch the fish. If you can’t find ahi tuna, you could always try to shrimp, halibut, red snapper, or salmon. Again, just make sure it’s fresh and sushi grade.
  • Sweeten it up. Instead of upping the heat with more citrus or peppers, you could add some sweeter ingredients like cucumber or pineapple.

Frequently Asked Questions:

How long can ceviche marinate?

You can let ceviche marinate for a couple days in the fridge, but the acidity of the lime juice continues to breakdown the proteins in the fish, and that will alter the texture and overall experience. I recommend making it the day you plan to serve it.

Should you freeze fish for ceviche?

If you are using sushi-grade, fresh fish, you don’t need to freeze the fish first. And any fish you do use should no longer be frozen when serving in your ceviche.

Can you make ceviche with freshwater fish?

Freshwater fish carry a much higher risk for parasites and other negative bacteria. There are some ways you could potentially still make it work, but I don’t think it’s worth the risk.

    Thoughts on using pickled red onions instead of raw red

    Did this recipe tonight and it was superb. I did the 2X serving just for myself (and because I just so happened to have 8oz of fresh caught tuna). I had to stop myself from eating the entire serving but man was it good.
