I stumbled upon this Baked Mahi Mahi dish in my kitchen last winter and it's now my regular go-to for family meals and when friends come over. What makes it special is how the soft, flaky fish complements my crunchy seasoned coating. Whenever I cook this, people always want to know how I made it, and I'm happy to tell them how easy yet fancy it turns out.
Delicious Fish Creation You'll Love
Mixing tangy Italian seasoning with my parmesan breadcrumb layer makes this mild fish taste amazing. My children who typically avoid seafood always want more. I've made this so many times and it works great for both rushed weekday meals and fancy dinner parties.
What You'll Need
- Mahi Mahi Filets: Look for bright, firm pieces as they bake up really well.
- Good Seasons Zesty Italian Seasoning: This mix ties all the tastes together wonderfully.
- Mayonnaise: My trick for keeping fish juicy and soft every time.
- Parmesan Cheese: Grate it yourself for the best crispy finish.
- Breadcrumbs: Panko gives extra crunch but standard ones work fine too.
- Lemon: Squeeze it fresh for the best flavor impact.
Mixing the Tasty Marinade
My marinade blends olive oil, garlic and that fantastic Italian seasoning. I'll throw in some fresh lemon zest or a bit of dill when I feel like switching things up. This easy mixture keeps the fish juicy while adding taste layers that make each mouthful wonderful.
Cooking Steps
- Get Your Fish Ready
- Cover your filets well with the marinade, making sure to hit every spot. I let them rest about 15 minutes while getting other stuff ready.
- Put Together That Crispy Coating
- Combine your breadcrumbs and parmesan with just enough olive oil so it sticks well. Layer it over each piece of fish.
- Pop It In The Oven
- They go into a 400°F oven for around 12 minutes. You can tell they're ready when they break apart easily with a fork.
Great Side Dish Ideas
This fish tastes awesome with soft rice pilaf and cooked veggies. In hot weather, a cool salad makes it perfect for lighter meals. Don't miss squeezing fresh lemon over everything right before you eat it really wakes up all the flavors.
Helpful Cooking Advice
Fresh fish really matters so I always try to find the newest Mahi Mahi available. Putting parchment paper on your baking tray stops sticking and makes cleanup way faster. Freshly grated parmesan melts just right into that golden top we want.
Try Something Different
I sometimes try other flavors like cajun spices or herbs straight from my garden. When I can't find Mahi Mahi, I use cod or halibut and they turn out great too. Adding some garlic butter sauce makes it taste even more amazing.
Keeping Extra Portions
Got some left? Keep it in your fridge for up to two days. I like warming it up in the oven or air fryer to keep the topping crunchy. Don't use the microwave as it just won't taste the same.

Totally! Firm white fish like halibut, cod, or even sea bass will work. Just tweak the cooking time for thicker cuts.

Prep it ahead by marinating the fish and making the topping. Put it together and bake fresh when you're ready to eat.
