Baked Cajun Mahi-Mahi Dinner Recipe


It’s a new year, which means we all are trying to eat a little healthier. Fish is always a go-to when I’m trying to eat healthy.

I also always keep fish in my freezer as an easy go-to meal. Mahi-mahi season is over here in Florida; however, my freezer still has quite a few filets left from a successful fishing season.

We enjoy mahi every other week for dinner. I almost always prepare it with Cajun seasoning and serve with rice, quinoa, or my favorite, couscous.

I like to make fish either on a Friday or Saturday night. It’s a simple meal to make and since we never have leftovers it’s perfect for the weekend.

We love to eat leftovers for lunch throughout the week, and let’s face it–who likes to eat fish the next day? You also don’t want to be known as the “stinky fish person” at work.

That was always one of my biggest pet peeves when I worked in the corporate world. It should be against the law to reheat any form of seafood in the microwave. I digress…

If you’re looking for a new way to cook mahi-mahi (or any steak like white fish) then I think you’ll love this Cajun style. A trinity mix of red, yellow, and green bell peppers as well as onions and fresh tomatoes are what makes this meal complete.

The Andouille sausage brings a little heat to the topping. If you’re on a low carb diet, you could easily make this without any starchy sides and just roast additional veggies.

Pro tip: dice the tomatoes, bell peppers, onions, and Andouille sausage the night before and store in a sealed container in the refrigerator.

Once you’re ready to make the meal, just pull out the chopped veggies and you’ve just save a good 15 minutes of dinner prep time.

I also don’t worry about thawing the fish. I bake it from frozen and it’s completely fine to do just that.

You can eat the fish, veggies, and sausage just as it is, or serve it on a bed of brown rice or quinoa. I typically throw in a pan of veggies to roast while the fish dinner cooks.

So, if you want to simplify dinner and keep it on the lighter side, I invite you to switch up your dinner routine and make my Baked Cajun Mahi Mahi Dinner tonight!
