Instructions

  1. Step 1: Brush 4 mahi-mahi fillets (6 oz each) with 2 tbsp olive oil and season both sides with 1 tsp sea salt and 1/2 tsp black pepper.
  2. Step 2: Preheat grill to medium-high heat (about 400°F). Grill fillets for 4-5 minutes per side until opaque and easily flaked with a fork.
  3. Step 3: In a bowl, combine 1 large diced avocado, 1 medium peeled and segmented orange, 1 medium peeled and segmented grapefruit, 1/4 cup finely chopped red onion, 2 tbsp chopped fresh cilantro, and 2 tbsp lime juice. Gently toss to mix.
  4. Step 4: Drizzle remaining 1 tbsp olive oil over the citrus and avocado salsa and season lightly with salt if needed.
  5. Step 5: Serve grilled mahi-mahi topped with a generous scoop of the vibrant citrus avocado salsa for a bright, fresh finish.

Frequently asked questions

How long does Grilled Mahi-Mahi with Citrus and Avocado Salsa 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 Citrus and Avocado Salsa?

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 Citrus and Avocado Salsa?

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.
