Ingredients

Instructions

  1. Step 1: In a bowl, combine 2 tbsp olive oil with 1 tsp ground cumin, 1 tsp smoked paprika, 1/2 tsp garlic powder, 1 tsp salt, and 1/2 tsp black pepper. Toss 1 lb mahi-mahi fillets cut into 8 strips in the mixture to coat evenly.
  2. Step 2: Preheat grill or grill pan to medium-high heat. Grill the mahi-mahi strips for about 3-4 minutes per side until opaque and grill marks form.
  3. Step 3: While fish cooks, prepare avocado crema by blending 1 medium ripe avocado with 1/2 cup sour cream, 2 tbsp lime juice, 2 tbsp water, and 1/4 tsp salt until smooth and creamy.
  4. Step 4: Warm 8 corn tortillas on the grill or stovetop until pliable. Assemble tacos by layering each tortilla with grilled mahi-mahi, 1/4 cup thinly sliced green cabbage, and a drizzle of avocado crema. Garnish with 1/4 cup chopped fresh cilantro.
  5. Step 5: Serve immediately with extra lime wedges if desired.

Frequently asked questions

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 Tacos with Avocado Crema?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep olive oil from drying out.

Can I substitute ingredients in Grilled Mahi-Mahi Tacos with Avocado Crema?

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 Tacos with Avocado Crema for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
