Blackened Mahi Mahi
Spice up your seafood with our blackened Mahi Mahi recipe. A filet of fish topped with our homemade Cajun seasoning then cooked to perfection!
Are you craving a spicy seafood dinner? Well, my friend, then look no further.
Our blackened Mahi Mahi recipe features a meaty fish filet seasoned with Kim’s custom Cajun spice mix.
The spices add a ton of heat and flavor to an already delicious piece of fish.
It should be noted that this recipe is very spicy. In fact, it was a little too spicy for me.
If that concerns you, then consider omitting the cayenne pepper and reducing the black pepper in the Cajun seasoning mix.
If this recipe sounds too spicy, you may want to try our oven baked mahi mahi, sheet pan salmon, maple Dijon salmon or baked cod with panko.
How to make Cajun seasoning?
First, grab a small bowl and a whisk. Next, add the garlic powder, onion powder, smoked paprika, oregano, salt, thyme, black pepper, and cayenne pepper to the bowl.
Last, use your whisk to combine the ingredients. The spice mix can be stored in a sealed container, in your cabinet for up to 3-months.
What side dishes go with this recipe?
Any of these sides will pair nicely with the spicy fish.
