Living in Florida, I've spent most of my life surrounded by fish. Every restaurant around usually has a local catch option on the menu (or two or three!), so I've become an avid fan of trying lots of fish varieties over the years.

One of my first favorite kinds of fish growing up was mahi mahi. Mahi mahi is mild and delicious and absolutely amazing when seasoned with my favorite blackened seasoning.

I like to prepare this mahi mahi recipe at least a couple of times a month for my family. Yup, the kids eat it, too! When you try it, I think you'll understand why we love it so much.

How To Bake Mahi Mahi

Baking mahi mahi in the oven is a very easy way to prepare it! First, season fresh thawed mahi filets with Cajun seasoning. Then bake the mahi for 18-20 minutes. Remove from the oven and top with a squeeze of fresh lemon juice. See below for a detailed ingredients list and instructions.


What is Mahi Mahi Fish

One question that a lot of folks out there have is: Is mahi mahi dolphin? The answer is yes. Mahi mahi is dolphin, but it is dolphinfish, not the air-breathing mammal that is most associated with the word dolphin. So, rest assured, your mahi mahi fish is of no relation to the porpoises you know and love!

What Does Mahi Mahi Taste Like?

Mahi mahi is a thick, lean, and meaty white fish that, when cooked, is moist with a mild, sometimes slightly sweet taste.

Baked Mahi Mahi Topping Variations

Want to add a little extra flair to your mahi? Try topping it with one of these creative accompaniments:
  • For a sweet twist, try a fruit salsa! You'll love mahi mahi with mango salsa or mahi mahi with pineapple salsa.
  • Top baked mahi mahi with cream sauce. A lemon dill yogurt sauce pairs well with fish.
  • Fresh herbs are a great mahi accompaniment. Serve your mahi mahi with chimichurri, a bold herb sauce.

What to Serve with Cajun Baked Mahi Mahi

Serve your mahi mahi with roasted vegetables, rice, and a side salad to make a complete meal.

Is This a Blackened Mahi Recipe?

While this recipe used the same seasonings as blackened mahi mahi, the method of baking disqualifies this from being actually blackened. Blackening refers to the preparation method where meat is coated in Cajun seasonings and cooked in a very hot skillet, creating a black, crisp sear on the meat. For this recipe, the flavors will be similar to blackened mahi mahi, but the outside of the fish with be soft and tender, not pan-sear crisp.

Is This Mahi Spicy?

I make this Cajun Seasoning in bulk, so I use it all the time. As is, the spice mix does have a little kick, especially if you use it liberally. To reduce the heat, omit the white pepper and cayenne pepper from the mix. I also highly suggest not skipping the lemon. The bright acidity from the lemon juice helps balance the full-flavored seasoning.
