Roasted Mahi Mahi

The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading all the way through for any tips or substitute suggestions, to ensure that you have any specialized ingredients and equipment required and that you understand the steps and timings involved.

Mahi-mahi is a fish from Hawaii (the Hawaiian translation of mahi-mahi is strong-strong), but can be found in all warm seas worldwide.

It is also known as lampuki, dorado, or dolphinfish (but it doesn’t have anything to do with dolphins, it’s because they jump out of the water like dolphins do!).

If you live in very warm or sub/tropical climates you’ll probably find this fish quite easily in your grocery store. Sadly, it’s highly unlikely here in the UK – however, it is a fish that freezes very well and can be bought frozen from online fishmongers. So if you’re looking to try a new type of fish, give mahi-mahi a try.

Mahi-mahi is a firm fish with a flaky texture and a sweet flavor. It is light pink when raw, but turns to a creamy white when cooked.

Mahi-mahi LOVES strong bold flavors, so the mango-chipotle sauce accompanies the fish perfectly!

It does not include staple ingredients such as oil, salt, and pepper, as you’re likely to have those in your kitchen already. The complete list of ingredients with measurements is found in the recipe card.

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog. I try to give American, imperial, and metric measurements in my recipes. Please note, you can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).

Recipe Tips

  • The mahi-mahi fillets release liquid as they bake. This is normal and does not harm the final results. However, to minimize the amount of liquid mingling with the mango while it roasts, simply arrange the mahi-mahi and the fruit on opposite sides of the sheet pan with the red onion positioned in between to create a barrier.

Roasted Mahi Mahi with Mango Chipotle Sauce

Yield: 4
Prep Time: 15 minutes
Cook Time: 25 minutes
Total Time: 40 minutes

You can create this fabulous yet deceptively easy Mahi Mahi dish by adding a sauce of mangos, red onion, thyme, lemon juice, and chipotle pepper to your roasted fish.


  • 4 (6-oz/170g) mahi-mahi fillets
  • 2 Tbsp olive oil, divided
  • Sea salt and black pepper, to taste
  • 2 large mangos, peel removed and diced
  • ½ large red onion, cut into thin wedges
  • 1 Tbsp fresh thyme leaves
  • 1 Tbsp fresh lemon juice
  • ⅛ tsp chipotle pepper
  • Fresh thyme sprigs, for garnish


  1. Pre-heat oven to 200°C/400°F/Gas 6 Line a large, rimmed baking sheet with aluminum foil or a nonstick baking sheet. Set aside.
  2. Add the mahi-mahi to the sheet pan and drizzle one tablespoon of olive oil on top. Use a pastry brush to spread the oil evenly over the surface of the fillets. Sprinkle with salt and black pepper, to taste. 

  3. Arrange the diced mango on the same baking sheet in a single layer without overcrowding.
  4. Add the red onion wedges and drizzle with the remaining olive oil. Spread the oil with a pastry brush until the onion is completely coated. Top the fillets and the onion with most of the fresh thyme leaves and season with salt and black pepper, to taste.

  5. Place the baking sheet in the center of the preheated oven for 18-20 minutes, or until the mahi-mahi is cooked through and flakes easily with a fork. Remove from oven and transfer to a plate. Set aside and keep warm.
  6. Transfer the roasted mango to a blender or food processor and place the onions back in the oven to roast for several more minutes while you prepare the mango sauce.
  7. Add the fresh lemon juice, chipotle powder, and few fresh thyme leaves to the blender or food processer with the roasted mango. Season with salt and black pepper, to taste, and pulse until smooth.
