Oven Roasted Mahi Mahi

Oven Roasted Mahi-Mahi with Roasted Grape Tomatoes and Roasted Asparagus is such and easy and healthy dinner that you can make in only 30 minutes. This meal is light, refreshing, and satisfying, while made in very short time. I used frozen Mahi-Mahi filets, as they tend to be cheaper, but fresh fish would be even better. For frozen filets, make sure you let them thaw before cooking.

Rubbed with garlic and olive oil, the fillets are drizzled with lemon juice, sprinkled with sea salt and black pepper. I added some mini grape tomatoes to the pan, as  it pairs very well with the fish. Oven Roasted Mahi-Mahi is tasty, healthy and full of flavor meal.

Oven Roasted Mahi Mahi Recipe Tips:

  • If you use frozen fish fillets, make sure you place them in the fridge way in advance so they can gradually thaw.
  • If using fresh fish fillets, I like to rinse them under cold water first and dry them with paper towels.
  • Don’t skip the lemon zest, its adds an amazing flavor to the fish.
  • It’s easiest to zest the lemons when they are whole, so first remove the zest from the lemon, before cutting it in half for juicing.
  • Adjust the garlic in this recipe to your own preference, if you like more add more.
  • If you would like to add a spicy kick to this recipe, sprinkle a little cayenne pepper over the fish fillets.
  • Don’t over cook the fish, roast until the fish fillets are just opaque in the center, about 10 minutes.

How do you choose a good Mahi Mahi fillet:

  • When possible, choose wild caught fish, as it taste better and is healthier.
  • Make sure the Mahi Mahi has a nice, vibrant color, that it looks fresh and moist.
  • Smell the fish, and don’t be fooled, as fish should NOT smell fishy. That is a red flag and a sign that it’s not fresh. Make sure the Mahi Mahi does not smell somewhat sour or like ammonia, in that case it has gone bad and you need to toss it.
  • Fresh Mahi Mahi has a mild aroma, and it should smell similar to the sea.

How long can you keep fresh Mahi Mahi in the fridge?

  • Mahi Mahi can be kept for an 1 to 2 days in the refrigerator before cooking, that if you just bought very fresh Mahi Mahi or if you just defrosted in the fridge frozen Mahi Mahi.
  • If you thawed the Mahi Mahi in the microwave or in cold water, you should cook it immediately.

How to make lemon zest?

Follow the easy steps below:

  • Rinse the lemon.
  • Set your tool over a cutting board. A microplane produces a very fine zest, perfect for baking and cooking. If you don’t have a microplane, use the smallest holes on an ordinary grater.
  • Grate the yellow skin of the lemon only. Grate just enough to get through the yellow skin, this way you can avoid the bitter white pith underneath.
  • Rotate the lemon and repeat. Once the white pith is exposed, rotate the lemon and zest the next strip of peel. Repeat until most of the peel is removed, or until you have enough zest for your recipe.

What wine pairs well with Mahi Mahi?

You could pick from Chardonnayor or Pinot Noir as these wines have good acidity, which you definitely need to cut through the oiliness of the fish.
