1. All About Mahi Mahi
Mahi Mahi is a white fish that is found in the Caribbean, Atlantic, and the Gulf Of Mexico. It is commonly called a flaky Hawaiian fish that is packed with vitamins and lean protein. It is a white fish with bright red veins along its body and weighs 22 kilograms on average.
Cooking a healthy mahi mahi doesn’t take much time at all, but you should do this in a ventilated kitchen or space since it uses strong seasonings for a blackened and charred effect.
In taste, mahi mahi isn’t too ‘fishy’, but it does have a rather distinctive flavor profile. Most people describe mahi mahi as a ‘sweet fish’. In terms of texture, it is quite flaky when it is fried. When cooking blackened mahi mahi, you don’t need much oil, which makes it a healthy alternative.
2. Tools Needed To Filet and Cook Blackened Mahi Mahi
A Deba knife is an excellent Japanese fish butchering knife that is used for whole fish like tuna and mahi mahi. This Deba knife from the Ronin series is designed to chop, gut, and filet fish with precision. Made with high-carbon Japanese steel, this knife has a thicker blade compared to western filet knives. The main purpose of this kitchen tool is to ensure less drag, thanks to its mirror-polished edge that is angled at a staggering 10º degrees.
Deba Knives have a blade that is flattened out from the blade to its edge. It becomes narrower towards the tip and helps perfect thin and soft cuts with little to no arm fatigue. They help remove scales and ribs of small and medium-sized fish, too.
- It can be used as a vegetable cleaver, too.
- Helps slice and gut fish cleanly without piercing the meat.
- It is equipped with a G10 Garolite handle.

A skillet is essential to make the best fish filet dinner recipes just like a scrumptious serving of blackened mahi mahi. Using a stainless steel skillet is best for serving fish that isn’t going to be undercooked. A skillet gives you the right amount of surface area to allow steam to flow inside the flesh without overcooking it.
This skillet from the Avalon series is the definition of function meeting form. This 12” inch frying pan and skillet hybrid responds tremendously well to temperature change and preserves the taste and texture of the fish you cook. It comes with a stainless steel lid designed to last a lifetime while locking in moisture and heat for cooking food.
- 5-Ply Copper Forged Foundation protects the skillet from staining and warping.
- A side stainless steel handle to strengthen its grip.
- Its functional and visual traits put this on the higher end of the price range.
- You may prefer a glass lid to see your food as it simmers instead of a stainless steel lid.
When you place your mahi mahi on the skillet, it should hiss and crackle. Within 2-3 minutes, the filet will begin to curl upwards. This is when you should use a thin, metal-slotted spatula to press down the filet. Once the filet makes contact with the pan, it won’t resist the meat anymore and you can continue cooking your mahi mahi.
3. Breaking Knife
This breaking and boning knife helps you pierce through the flesh of the mahi mahi neatly and gut or filet it seamlessly. The curved tip helps in separating the bone from the spine, too. The curved blade is made with high-carbon ThyssenKrupp steel and helps you contour and de-bone quite neatly compared to a standard knife. Remember to never use a knife with serrations along the blade, as it will tear through the skin of your mahi mahi or any other fish that you’re cooking, such as salmon.

3. The Perfect Temperature To Cook Mahi Mahi
When you place a filet of seasoned fish on the stove, oven, or grill, especially for a portion of blackened mahi mahi, getting the temperature right is essential. The tenderness of your mahi mahi will depend on two factors – The skillet being used, and the temperature it is being cooked at.
Cooking Mahi Mahi In The Oven
Since mahi mahi is a ‘flaky’ fish, you don’t want to overcook it. The correct temperature to cook mahi mahi is 137º degrees F, or 58º degrees C. But, this depends on the size of the filet, so if you’re cooking mahi mahi for the first time, it is better to cook it at 130º F - 135º F. If you’re making blackened mahi mahi, you don’t want to cook the fish on high heat. The mahi mahi is cooked if the internal temperature reaches 145º F.
Cooking Mahi Mahi On The Stove or Grill
Once you place your mahi mahi filet on the stove or grill, cook each side for about 3 minutes before flipping it. Once you’ve cooked both sides for 5 minutes collectively, use a digital meat thermometer to check the temperature. Once the resting temperature reaches 145º F, turn the heat down immediately.
Cover the grill or skillet with a lid for 2 minutes and let the fish steam evenly. Check the temperature once again. When the fish is close to getting done, the temperature should be anywhere between 137º F and 145º F. Rest the fish for 8-10 minutes. Then, your blackened fish is ready to be served.

- Pour a tablespoon of butter into the mixture and pat it on the fish so the spices can firmly stick to it. Remember to season both sides well!

- Once the butter is nice and hot, place the mahi mahi on the skillet and cook for 3 minutes on each side.
- Cook for 4-5 minutes on each side if you’re using the grill.
- Once your mahi mahi is cooked, use a meat thermometer to check the internal temperature.
- If the temperature reaches 145ºF, your fish is cooked and ready to be served along with a mango and red onion salsa.
