FAQs

Can I use frozen Mahi Mahi instead of fresh?

Yes, just make sure to thaw the fillets completely and pat them dry before seasoning and baking to ensure the best texture and flavor.

What if I don’t have all the spices for the blackening mix?

You can simplify the seasoning by using a pre-made Cajun or blackening spice blend, or use the key spices you have on hand such as smoked paprika, garlic powder, and cayenne pepper.
