Instructions

  1. Step 1: Preheat grill to medium-high heat, about 400°F. Brush 4 mahi-mahi fillets with 2 tbsp olive oil and season both sides with 1/2 tsp salt and 1/4 tsp black pepper.
  2. Step 2: Grill the fillets for 4-5 minutes per side until opaque and easily flaked with a fork. Remove and keep warm.
  3. Step 3: In a medium bowl, combine 1 cup diced mango, 1 cup diced avocado, 1/4 cup finely chopped red onion, 3 tbsp chopped fresh cilantro, 2 tbsp freshly squeezed lime juice, 1/2 tsp salt, 1/4 tsp black pepper, and 1 small minced jalapeño if using. Toss gently to combine.
  4. Step 4: Spoon the mango-avocado salsa over the grilled mahi-mahi fillets and serve immediately with lime wedges if desired.

Frequently asked questions

How long does Grilled Mahi-Mahi with Mango-Avocado Salsa and Cilantro take to make?

Total time is about 25 minutes (15 min prep + 10 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Grilled Mahi-Mahi with Mango-Avocado Salsa and Cilantro?

Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish). Store any fresh salsa or citrus-based garnish in a separate container — it keeps for up to 2 days. Freeze cooked fish (without fresh garnishes) for up to 3 months; thaw overnight in the fridge and reheat gently at 275°F until just warmed through to preserve texture.

Can I substitute ingredients in Grilled Mahi-Mahi with Mango-Avocado Salsa and Cilantro?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Grilled Mahi-Mahi with Mango-Avocado Salsa and Cilantro for a different number of people?
