Easy Mahi Mahi Recipe with Lemon Garlic Sauce. A simple and wildly delicious way to prepare and serve this tender, flakey, and popular white fish.

Skillet filled with fully cooked mahi mahi fillets cooked in a lemon butter sauce and garnished with fresh parsley.

Perfect Mahi Mahi Recipe

Every couple of weeks I get a huge craving for fish. This craving usually evolves into one of a handful of different recipes including fish sticks, baked fish with tomatoes, artichokes, and feta, or some version of pan-seared fish usually served with a big scoop of tartar sauce.

This week, however, I was feeling inspired by my favorite chicken piccata recipe and this (reader favorite) garlic butter sauce. Picking mahi-mahi fish rather than my usual go-to codfish fillets, the result was this easy, 30-minute pan-seared mahi-mahi dinner. Delicious, flavorful, and made with just 7 ingredients – that’s it! 

One of my favorite parts about this recipe (aside from the fish, of course) is that it pairs so well with just about everything. From rice to couscous, pasta to potatoes (yes, you really want buttery mashed potatoes here), to every single veggie you can possibly imagine. 

Who’s ready to start cooking?

What is Mahi Mahi?

The mahi-mahi, also known as the common dolphinfish (Coryphaena hippurus) or dorado, is a surface-dwelling ray-finned fish commonly found off-shore in the waters around the Gulf of Mexico, Costa Rica, Hawaii, and the Indian Ocean. The name “mahi-mahi” is derived from the Hawaiian word for “very strong”.

Sustainability is determined by a number of factors, the most important being where and how the mahi-mahi is caught.

According to the Monterey Bay Aquarium Seafood Watch, 

  • Best – mahi-mahi (aka dolphinfish, dorado) caught in the U.S. Atlantic with handlines and hand-operated pole-and-lines or trolling lines.
  • Second-best – mahi-mahi caught in the Eastern Central Pacific in the unassociated purse seine fishery or by U.S., Ecuadorian and Panamanian fleets. Understand that there are some issues with at-risk or overfished species in these areas.
  • Avoid – All other imported mahi-mahi from the Atlantic, Pacific, and Indian Oceans.

Note: most of the dolphinfish sold in the U.S. is imported which means that most of the mahi-mahi sold in the U.S. is on the avoid list.

Ingredients and Frequently Asked Questions

  • Mahi Mahi fillets
  • Salt + Pepper
  • Olive oil
  • Butter
  • Whole garlic cloves
  • Fresh whole lemons (for juicing and slicing)
  • Fresh parsley

Can I use any other white fish to make this recipe?

If you can’t find mahi-mahi, replace it with another type of flakey white fish. My top picks include cod, halibut, and tilapia. Total cooking times may vary slightly depending on the size and overall thickness of your fillets.

Can I grill my mahi-mahi instead?

Instead of pan-searing your mahi-mahi, why not try grilling? Just as quick as cooking on the stovetop, here’s how you’ll do it:

  1. Preheat your gas grill to medium-high heat (or 450 degrees F).
  2. Season your fish with salt and pepper, or other desired seasoning (try adding a dash of onion powder or garlic powder or go all-out with your favorite cajun seasoning, blackening seasoning, etc.) and brush both sides with olive oil.
  3. Place each fillet directly on the grill. Grill for approximately 4-5 minutes per side. It’s fully cooked when it reaches an internal temperature of 137 degrees F.
  4. Remove from the grill and smother in your homemade garlic butter sauce.

How are leftovers?

First and foremost, don’t try to freeze leftovers and reheat later. Yes, it will be edible, but no, it will not even come close in taste or texture to the original. Your best bet? Store leftovers in a sealed container and in the refrigerator for up to 2-3 days.  I typically reheat my fish in the microwave at 30-second intervals until it is just heated through. You will probably notice that your fish isn’t as tender or flakey – that’s normal.

How to Cook Mahi Mahi

1. Season the fillets.

But first, pat each mahi-mahi fillet dry with paper towels. This guarantees that flavorful, golden sear we’re after. Next, season both sides of your fish fillets with salt and lemon pepper or your own combination of seasoning. Options include salt and black pepper, garlic powder, onion powder, and paprika.

2. Prepare the ingredients for the garlic butter sauce.

Once you get started cooking things move pretty fast, so I like to have everything prepared and ready to go before I start.

Wash your lemons. Then, thinly slice one lemon and juice the other lemon into a small bowl so that you have approximately 4 tablespoons of fresh lemon juice. Mince the fresh garlic cloves and set aside.

3. Pan sear the mahi-mahi.

Add the olive oil to a large stainless steel skillet or cast-iron skillet set over medium-high heat. Once the olive oil is nice and hot, carefully add each fillet. Sear, undisturbed, until nicely golden brown and the sides are cooked just past halfway up the fillets. This will take about 4 minutes depending on the thickness of your fish (the fish is cooked when it’s no longer opaque-looking).

Flip and continue to cook on the other side until just cooked through, about 2-4 minutes more (mahi-mahi should reach an internal temperature of 137°F). Remove from heat and transfer fillets to a serving plate.

4. Prepare the lemon garlic sauce.

Immediately start the sauce. In the same skillet (or in a new one), heat the butter, lemon juice, and lemon slices over medium heat. Heat until the butter is melted and just starting to bubble. Stir in the garlic, reduce heat to low, and continue to cook for 1 minute, or until the garlic is lightly golden. Stir in the fresh minced parsley and drained capers (optional).

5. Combine and serve.

Spoon the garlic butter sauce over the mahi-mahi and serve immediately with all your favorite side dishes.

What to Serve with Mahi Mahi?

There are so many great things to serve with this mahi-mahi recipe. A few healthy favorites include brown rice, wild rice, or even cauliflower rice. Dry something a little creamier like buttery mashed potatoes or (my favorite) low-carb cauliflower mashed potatoes. Of course, when in doubt, big chunks of warm bread are always fantastic dunked in some extra butter sauce.

Add some greens with a light salad, roasted beets, or steamed veggies of any kind.

    Delicious way to serve this fish! The only way my daughter will eat it. The only thing I change is I add a little of the lemon zest for some extra lemony flavor, it’s so good!

    Was able to put together a quick and delicious lunch with this recipe. Normally, I don’t have time to cook lunch during the work day, but this one was done in less than half an hour (cooked the sauce separately, so it was ready when the Mahi Mahi was done. Quality food at a quick pace!

Thank You

    Did this tonight, super easy and super delicious. Used Tajine instead of lemon pepper, and very glad of it. Served with roasted garlic mashed (potato) cauliflower and wilted spinach.
    A perfect recipe to do after a long day at work when we want something luxurious, healthy and quick.
    THANK YOU!

    First time making mahi and it turn out great. Did it on the stove over medium heat and California EVOO. I dried the fillet as suggested. I used lemon pepper seasoning, onion salt and smoke sea salt and into the pan it went. Flipped at 3 minutes and I had a nice blackened crust. The sauce was excellent and when I poured it over the fillet I was felt like I should take a picture. I’ve paid big money for this dish in a restaurant but this one tops them all.

    I don’t usually try with Mahi Mahi, but this turned out good. Served with spinach salad and mashed potatoes. We put all the extra garlic butter sauce on the potatoes!

    I like it, but… there was way too much lemon for me to stomach it. Next time I’ll use half a lemon instead. Maybe I used too much lemon pepper seasoning? I tried to follow the recipe as close as possible.
