Oven Baked Mahi Mahi
Growing up as a kid there was usually a weeknight dinner of fish sticks and macaroni and cheese. Even my own kids experienced this weeknight dinner – who else has this on their regular rotation??
Now, there’s nothing wrong with frozen fish sticks. There are quite a few decent selections out there; however, when I started looking at gluten-free options, I found that oven baked Mahi Mahi was a quick and easy choice and no worries about breading that contained gluten.
A quick way to test Mahi Mahi for doneness is to use a fork and see if it flakes easily. But, I can remember when I first started cooking fresh fish I did the fork test and still wasn’t sure if it was done. I wanted a little more piece of mind. If you’re like me, then checking the temperature with a meat thermometer is the way to go.
We get this question a lot – and the answer is really up to you and how you define healthy. Mahi Mahi is an excellent source of protein, vitamin B12, Niacin while also being low in total fat.
Yes, you can cook your Mahi Mahi fillets frozen; however, I would recommend thawing first. To safely thaw the fish, place in the refrigerator the night before and let it gradually thaw overnight.
