Grilled Tuna Steak with Fresh Mango-Cilantro Salsa (Healthy fats and freshness)
By the QuiteRecipes team (Jamy & Kaïna) | Food Service Professional, Early Childhood Expert & Parents
Seared tuna steaks with a bright mango-cilantro salsa — omega-3 protein finished with freshness instead of salt or rich sauce.
A tuna steak is one of the leanest ways to get serious omega-3s, and it asks for very little — a hot pan, a spice rub, and a riot of mango and cilantro on top. We cook the fish all the way through and let the salsa supply the freshness, so the meal needs barely any salt at all.

👨🍳 Instructions
Mix the mango, red onion, jalapeño (if using), cilantro, and half the lime juice for the salsa; set aside.
Pat the tuna dry; rub with the olive oil, ground coriander, lime zest, and black pepper.
Heat a grill pan or skillet over high heat until smoking.
Cook the tuna 3–4 minutes per side until opaque all the way through and firm to the touch (145°F / 63°C).
Rest 2 minutes, then slice against the grain.
Serve the tuna with the mango salsa and a squeeze of the remaining lime.
⚠️ Common Mistakes
- ✕
Overcooking the tuna until it's chalky; pull it at the opaque stage.
- ✕
Making the salsa a day ahead, when it loses all its sparkle.
- ✕
Adding salt to the rub; coriander, lime, and the salsa carry the flavor.
🔄 Variations
Swap tuna for grilled salmon or another firm fish.
Use peach or pineapple when mango is out of season.
Add diced avocado to the salsa for extra creaminess.
🧊 Storage
- 📦
Best eaten the day it's made; leftover tuna flakes into a salad the next day.
- 📦
Store the salsa separately, up to 24 hours.
💡 Chef Tips
Tip 1: Cook tuna thoroughly but stop the moment it's opaque, and it stays surprisingly juicy.
Tip 2: A properly hot pan gives a golden crust — don't overcrowd or the tuna steams.
Tip 3: Make the salsa just before serving; mango browns and softens if it sits too long.
Tip 4: Ask for skipjack or yellowfin over albacore — they're smaller, lower-mercury tunas.
❓ FAQ
Q
Why skipjack and not albacore? Albacore is a larger, longer-lived tuna that carries more mercury; skipjack, yellowfin, and chunk light are the lower-mercury choices.
Q
Is tuna a good omega-3 source? Absolutely — a tuna steak in a week covers most adults' omega-3 needs.
Q
Is the mango too much sugar? Fresh fruit sugar in a modest serving, balanced with protein and vegetables, is part of a healthy plate.
