It’s a new year which means we all are trying to eat a little healthier. By now we are closing in on the end of the month and maybe you’ve fallen off the band wagon it a little bit. I’m here to help give you a new healthier recipe that will hopefully jump start you back into eating healthier. My Baked Cajun Mahi Mahi Dinner is done within an hour.
Fish is always a go-to when I’m trying to eat healthy. Mahi mahi season is over here in Florida; however, my freezer still has quite a few fillets left from a successful fishing season.
We enjoy mahi every other week for dinner. I almost always prepare it with Homemade 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.

Directions
- Preheat oven to 425 degrees Fahrenheit.
- In a 9 x 12 glass baking dish, place the diced plum tomatoes, bell peppers, onion, and andouille sausage. Drizzle one tablespoon of the olive oil and sprinkle one teaspoon of the cajun seasoning on top. Mix well and then push to the sides of the dish leaving a large hole for the mahi mahi.
- Drizzle one tablespoon of olive oil on the empty spot in the baking dish. Then add the large frozen mahi mahi filet to the dish (skin side down). Drizzle the remaining one tablespoon of olive oil on top and sprinkle the remaining one teaspoon of cajun seasoning on top of the fish.
- Place aluminum foil on top of the glass baking dish and bake for 25 minutes. Then remove the aluminum foil from the dish and bake for an additional 15 minutes until internal temperature reads 165 degrees Fahrenheit.
- Remove from the oven, carefully cut the fish in 3-4 pieces depending on the size of the filet. Place fish on plates and top with tomato, pepper, sausage mixture. Enjoy immediately.
Recipe FAQS
This baked mahi recipe makes enough to serve 4 people. I always serve this meal with some sort of starch like rice or quinoa.
Two ways to tell that mahi is done.
-The first way is by the color. The fish will have an opaque color when fully cooked through.
-The second way is the fish should easily flake with the tines of a fork.
Yes, you can cook the mahi mahi with the skin on. This will keep it all in tact. Make sure you remove the skin before eating. Always keep the skin on when grilling or else your fish may fall into the grill grates.
Yes, you can cover your fish when baking. By covering with aluminum foil you are essentially steaming the fish. Remove the foil before its done to crisp the top of the fish.
Expert Tips
- Fresh Fish – You can bake this with fresh fish. Do not tent fish and bake for 15-20 minutes or until fork tender and flaky.
- Frozen Fish – I also don’t worry about thawing the fish. I bake it from frozen and it’s completely fine to do just that.
- Prep Ahead – Dice the tomatoes, bell peppers, onions, and andouille sausage the night before and store in a sealed container in the refrigerator. Once your ready to make the meal just pull out the chopped veggies and you’ve just save a good 15 minutes of dinner prep time.
