This easy tuna ceviche combines sushi‑grade ahi tuna with crunchy vegetables, sweet mango, creamy avocado, spicy jalapeño and bright lime juice. Serve it as a light, protein‑rich appetizer with tortilla or plantain chips, or make it the centerpiece of a meal atop crispy tostadas or a rice bowl. It’s fresh, fast and full of vibrant flavor.

Erica’s thoughts:
If you know me, you know I love poke bowls. I used that inspiration to create this tuna ceviche, which highlights sushi‑grade ahi tuna in a citrus “cooking” rather than a soy‑based marinade. As the lime juice denatures the fish, the vibrant pink turns a paler, opaque color—that’s completely normal. Paired with crunchy cucumber, sweet mango and herbaceous cilantro, the result balances texture and brightness.
I often scoop this ceviche with tortilla chips, but it’s equally good piled on a tostada or served over rice for a poke‑style bowl. It’s simple to prepare, packed with nutrients like heart‑healthy fats and lean protein, and comes together in minutes. Here’s what you’ll need and how to make it.
Ingredients you’ll need to make tuna ceviche:

Ahi tuna: Look for sushi‑grade or sashimi‑grade ahi (yellowfin) tuna at your grocery store’s fish counter. It’s often frozen; thaw it in the refrigerator before using.
Mango: Ataulfo (honey) mango is ideal—sweeter and less fibrous—but any ripe mango will work.
Avocado: Use a firm but ripe avocado so it holds its shape when cubed.
Cucumber: English or Persian cucumbers have fewer seeds and less excess water.
Jalapeño: Adds a mild heat. Omit or substitute serrano or hot sauce if you prefer milder or different spice.
Red onion: Finely diced red onion adds a sharp, complementary bite.
Cilantro: Fresh cilantro brings a bright, herbaceous lift that pairs perfectly with lime and mango.
Salt and pepper: Kosher or sea salt and freshly cracked black pepper to taste.
Lime juice: Freshly squeezed lime juice “cooks” the tuna by denaturing proteins and gives ceviche its signature tang.
Olive oil: A good extra virgin olive oil adds silkiness and tempers the acidity—use a quality bottle you enjoy.

How to make tuna ceviche:
Use a sharp knife to cut the tuna into small, even cubes. Dice the mango, avocado and cucumber to similar sizes so the texture is uniform. In a large bowl, combine the tuna, mango, avocado, cucumber, jalapeño, red onion and cilantro.


Season with salt and pepper, then pour in the lime juice and olive oil. Gently toss to coat everything evenly. Refrigerate the mixture for 20 minutes up to an hour—longer will further “cook” the tuna and soften the avocado. Serve chilled on crispy tortillas, as tostadas, with tortilla chips for dipping, or over rice.


Ways to serve tuna ceviche:
- As an appetizer with tortilla or plantain chips.
- Piled on a crispy corn tortilla for a tuna tostada.
- On top of steamed rice with green onions and black sesame seeds for a poke‑style bowl.
- As part of a light meal alongside other small plates or salads.

FAQs
Fresh sushi‑grade tuna is recommended for true ceviche because canned tuna is already cooked and has a different texture. That said, if you want a quick pantry version, canned tuna combined with the other ingredients will still be tasty.
Choose sushi‑grade tuna and keep it properly chilled. The lime juice helps reduce bacterial risk by denaturing surface proteins, but always purchase fish from a reputable source and handle it safely.
Ahi (yellowfin) tuna is ideal for this ceviche, though other sashimi‑grade fish can be used depending on availability.
Keep leftovers in an airtight container in the refrigerator for up to 3 days. Note that the avocado may brown and the texture will soften over time, so it’s best enjoyed within the first day or two.
