Perfect for:
- Anyone trying wahoo for the first time (spoiler: you’ll love it)
- Weeknight meals that feel restaurant-worthy
- Light, healthy dinners with big flavor
Ingredients You’ll Need
- 1 lb wahoo (ono) fillets – about 2 medium fillets, skin removed, cut about 1 inch thick
- 2 tablespoons olive oil – for coating the fish and keeping it moist
- 2 tablespoons fresh lemon juice – adds brightness and prevents dryness
- 1 tablespoon lime juice (optional) – a touch of extra citrus for balance
- 3 cloves garlic, finely minced – fresh garlic brings the most flavor
- 1 teaspoon Italian seasoning – a simple herb blend that pairs well with wahoo
- 1 teaspoon fresh rosemary or thyme (optional) – for a more aromatic finish
- ½ small red onion, thinly sliced – adds sweetness as it roasts with the fish
- 1–2 tablespoons unsalted butter, cut into small dots – melts into the fish for richness
- ¾ teaspoon kosher salt, divided – seasons both the marinade and fillets evenly
- ¼ teaspoon freshly ground black pepper – enhances the natural sweetness of the fish
- 1 tablespoon fresh parsley, chopped – for garnish and a touch of color at the end
Step-by-Step Instructions
Step 1: Preheat the oven and prepare the pan
Set your oven to 350°F (180°C) and position the rack in the center. Line a baking dish or small sheet pan with foil and lightly brush it with olive oil to prevent sticking.
Step 2: Mix the citrus-garlic marinade
In a small bowl, whisk together the olive oil, lemon juice, lime juice (if using), garlic, Italian seasoning, herbs, salt, and pepper. This mixture will keep the wahoo moist while baking and give it a fresh, zesty flavor.
Step 3: Dry and season the wahoo fillets
Pat the fillets very dry with paper towels. Place them on the prepared pan and sprinkle lightly with a pinch of salt. Drying first helps the marinade cling and ensures better texture.
Step 4: Add marinade, onion, and butter
Spoon about two-thirds of the citrus-garlic marinade evenly over the fish. Scatter thinly sliced red onion around the fillets, then dot the tops of the fish with small pieces of butter.
Step 5: Cover and bake
Fold the foil loosely over the fish to make a tent and seal the edges. Bake for 12–15 minutes (for fillets about 1 inch thick) until the fish is nearly opaque in the center.
Step 6: Broil for a golden finish
Open the foil, spoon some pan juices over the fillets, then switch the oven to broil. Broil for 2–4 minutes until the tops take on a light golden color.
Step 7: Check doneness and serve
Test with a fork: the wahoo should flake easily and register 145°F (63°C) at its thickest part. Let rest for 2–3 minutes, drizzle with the remaining marinade, sprinkle with parsley, and serve with fresh lemon wedges.

Frequently Asked Questions About Wahoo Fish
Can I cook wahoo from frozen?
Yes, but for the best texture, it’s recommended to thaw wahoo overnight in the fridge before cooking. If you’re baking it from frozen, add about 5–8 extra minutes to the cooking time and cover tightly with foil to retain moisture.
What’s the ideal internal temperature for baked wahoo?
Wahoo should reach an internal temperature of 145°F (63°C). At this point, it flakes easily with a fork and is opaque throughout. Don’t go much beyond that, it dries out quickly due to its low fat content.
Is wahoo fish healthy?
Absolutely. Wahoo is high in lean protein, low in calories, and contains essential nutrients like vitamin B12, selenium, and omega-3s. It’s a great choice for balanced diets, including low-carb and keto-friendly plans.
How does wahoo taste compared to other fish?
Wahoo has a mild, slightly sweet flavor with a firm, flaky texture. Many people describe it as somewhere between mahi-mahi and swordfish, making it a great choice for those who don’t like overly “fishy” fish.
What’s the best way to season wahoo?
This recipe uses a simple blend of lemon, garlic, and herbs, but wahoo also pairs beautifully with:
– Cajun seasoning
– Coconut-lime sauces
– Mediterranean flavors like olives and capers
