The Ono (Wahoo) Flavor and Texture Profile
To find the best substitutes, it's essential to first understand the characteristics of ono fish. Ono, or wahoo, is a lean, white-fleshed fish celebrated for its mild, slightly sweet flavor with no "fishy" aftertaste. Its texture is firm, yet delicate and flaky, holding up well to various cooking methods, especially grilling and searing. Because of its low fat content, it cooks quickly and can dry out if overcooked. Fresh ono has a pale white to slightly pinkish color that becomes opaque when cooked. These characteristics—mild flavor, firm texture, and lean white flesh—are the benchmarks for identifying suitable alternatives.
Best Substitutes: What Is Ono Fish Similar To?
Mahi Mahi: The Closest Match
Mahi mahi is one of the most frequently recommended and widely available substitutes for ono. It shares a similar mild, sweet flavor profile, though some may find it slightly less delicate. Its texture is also firm but flakes more readily than ono, requiring careful cooking to avoid drying it out. This makes mahi mahi an excellent all-purpose substitute, especially for grilling, pan-searing, and fish tacos. It also has pinkish-colored flesh that turns white when cooked, resembling ono.
Cod and Halibut: Excellent Mild, White Fish
For a mild flavor and firm white flesh, both cod and halibut are fantastic alternatives to ono. Cod, in particular, has a mild taste and cooks up with a snow-white, flaky texture that is very similar to ono. Halibut, while also firm and mild, can sometimes be even firmer and less delicate than ono. These are great choices for recipes where the flavor of the fish should not overpower the other ingredients, such as in ceviche or dishes with flavorful sauces. Both fish are also lean, so care should be taken not to overcook them.
Ahi Tuna: For a Meaty, Steak-like Texture
While ono is a relative of the mackerel family, ahi tuna is a closer relative to the mackerel family and offers a firmer, leaner, and more steak-like texture than ono. Ahi tuna has a stronger, more pronounced flavor compared to ono's mild sweetness. It holds up exceptionally well to high-heat cooking methods like grilling and searing, where it can be cooked rare or medium-rare. When substituting ahi for ono, keep in mind the flavor difference and be mindful of its quicker cooking time.
Swordfish: The Firmest Option
Swordfish is another fish with a steak-like texture, making it a good substitute for ono in recipes where firmness is the primary concern, such as kebabs. However, it is also a leaner fish and is more prone to drying out if not cooked properly. The flavor of swordfish is generally richer and less sweet than ono, which may not be a perfect match for all recipes.
Opah: The Versatile Choice
Opah, also known as moonfish, offers a unique textural experience that can be similar to ono, though it varies by cut. The pectoral muscles can have a texture similar to beef, while other parts are closer to tuna or salmon. Opah has a mild and rich flavor, making it a versatile option for many preparations. It is excellent for grilling, smoking, or baking, though it may not be as easy to find as mahi mahi or cod.
Other Worthy Mentions
Other potential substitutes include striped bass, snapper, or even king mackerel (if you can find a milder-flavored variety). The key is to look for firm, white-fleshed, mild-tasting fish that can stand up to your desired cooking method. Always aim for the freshest possible fish for the best results.

Choosing the Right Ono Substitute for Your Dish
When you're deciding on a substitute for ono, consider the cooking method you plan to use and the desired flavor profile. For recipes that rely on the fish's firm texture, such as grilling or kebabs, a firm-fleshed alternative is best.
For grilling and searing:
- Mahi Mahi
- Swordfish
- Ahi Tuna (if you prefer a richer flavor)
- Halibut
For baking or frying:
- Cod
- Mahi Mahi
- Halibut
- Snapper
For raw applications (sashimi, poke, ceviche):
- Mahi Mahi (ensure it is sushi-grade)
- Ahi Tuna (ensure it is sushi-grade)
- Cod (good for ceviche)
Tip for cooking lean fish: Because ono and many of its substitutes are lean, they can easily dry out. Cook for shorter periods at high heat and use marinades or flavorful sauces to keep the fish moist. Try a simple garlic and lemon marinade or a tropical fruit salsa to complement the fish's delicate taste.
Conclusion
While ono (wahoo) holds a special place in the culinary world for its firm texture and mild, sweet flavor, a number of other delicious fish can serve as excellent substitutes. For the closest match in both taste and texture, mahi mahi is the top contender. If a milder flavor is your priority, cod or halibut are superb choices. For a meatier, steak-like result, look to ahi tuna or swordfish. By understanding the unique properties of each alternative, you can confidently find the perfect fish to bring that same "delicious" essence to your next meal.
Final Thoughts on Sourcing
When purchasing any substitute for ono, always check for the freshest possible product. The fish should have a clean, fresh smell, and the flesh should be firm and moist. Sourcing sustainably is also an important consideration. For a guide on sourcing sustainable seafood, check resources like the Monterey Bay Aquarium's Seafood Watch program. Finding the right substitute allows you to enjoy a similar culinary experience even when ono is not available.
