After discovering this Baked Mahi Mahi recipe in my kitchen last year it's become my go to dish for both casual dinners and when I'm hosting guests. The magic lies in how the tender flaky fish pairs with my crispy seasoned topping. Every time I make this someone asks for the recipe and I love sharing how simple yet impressive it is.
Your New Favorite Fish Dish
The combination of zesty Italian seasoning and my parmesan breadcrumb topping transforms this mild fish into something extraordinary. Even my kids who usually turn their nose up at seafood ask for seconds. I've served this countless times and love how it fits perfectly into both quick weeknight dinners and special occasions.
Everything You Need
- Mahi Mahi Filets: I always pick firm bright looking pieces they cook up beautifully.
- Good Seasons Zesty Italian Seasoning: This seasoning blend brings all the flavors together perfectly.
- Mayonnaise: The secret to keeping your fish moist and tender every time.
- Parmesan Cheese: Fresh grated creates the most amazing crispy topping.
- Breadcrumbs: I love using panko for extra crunch but regular works great too.
- Lemon: Fresh squeezed makes all the difference here.
Creating the Perfect Marinade
My marinade combines olive oil garlic and that wonderful Italian seasoning. Sometimes I add fresh lemon zest or a pinch of dill when I want to change things up. This simple mix keeps the fish tender while adding layers of flavor that make every bite special.
Let's Get Cooking
- Prep Your Fish
- Brush your filets generously with the marinade making sure to coat every inch. I let them sit for about 15 minutes while I prep everything else.
- Make That Crunchy Top
- Mix your breadcrumbs and parmesan with just enough olive oil to make it stick together nicely. Spread it over each filet.
- Time to Bake
- Into a 400°F oven they go for about 12 minutes. You'll know they're done when they flake easily with a fork.
What Goes Well With It
I love serving this fish alongside fluffy rice pilaf and roasted vegetables. During summer months a fresh salad makes it perfect for lighter dinners. Don't forget to squeeze fresh lemon over everything just before serving it brightens all the flavors.
My Best Kitchen Tips
Quality fish makes all the difference so I always look for the freshest Mahi Mahi I can find. Lining your baking sheet with parchment paper prevents any sticking and makes cleanup so much easier. Fresh grated parmesan melts perfectly into that golden crust we're looking for.
Switch Things Up
Sometimes I play around with different seasonings like cajun spices or fresh herbs from my garden. When Mahi Mahi isn't available I use cod or halibut they work beautifully too. A drizzle of garlic butter sauce takes it to another level of delicious.
Saving It For Later
If you have leftovers store them in the fridge for up to two days. I prefer reheating in my oven or air fryer to keep that lovely crispy top. Skip the microwave it just doesn't do this dish justice.

Frequently Asked Questions
- → Why use both yogurt and mayonnaise?
Greek yogurt adds tanginess while mayo adds richness. Together they create a perfectly creamy topping that won't dry out while baking.

Yes, any firm white fish like cod, halibut, or sea bass works well. Adjust cooking time based on thickness.
- → How do I know when the fish is done?
Fish should flake easily with a fork and be opaque throughout. The topping should be golden brown.
- → Can I make this ahead?
You can marinate the fish and prepare the topping separately up to a day ahead, but assemble and bake just before serving.
- → What can I substitute for the Italian seasoning packet?
Make your own blend with dried herbs like basil, oregano, garlic powder, and onion powder.
