I’ve always been a huge fan of fish. I love it when it’s fresh, but I’m not terribly picky. Recently I’ve fallen in love with Baked Mahi Recipe that is to die for!

This Baked Mahi Recipe is a flaky, juicy treat that’s easier than you might believe! I’ve got some great tips for cooking fish so don’t worry if you’re not an expert.
This Mahi mahi fish is tender with a mild flavor, coated in a spice mix that’s zingy enough to wake up your tongue and keep you coming back for more.
Picture this: golden mahi mahi fillets hot from the oven, brushed with butter that melts like a dream—yum!
Fresh Mahi Mahi is really the way to go. There aren’t too many fish that can beat it. Frozen is great too, though, just so you know.
I think this is the best way to enjoy fresh fish, baked quick in 10-15 minutes with simple ingredients. Simple is best in general when it comes to fish. You really don’t want to over-do it.
This recipe is perfect for a chill dinner or when you want to impress your crew without flapping around like a fish out of water, haha!
Grab your sheet pan, and let’s make this baked mahi recipe that’s so tasty, it’ll be like you caught it yourself off a fishing boat—minus the seasickness!

FREQUENTLY ASKED QUESTIONS ABOUT THIS RECIPE:
CAN I USE A DIFFERENT FISH?
Oh, totally! Swap mahi mahi filets for any white fish like cod, tilapia, or even dolphin fish (don’t worry, it’s just another name for mahi!).
They’ll all bake up flaky and delicious—just check that internal temperature to make sure it’s cooked!
CAN I USE A DIFFERENT SEASONING?
You bet! Ditch the simple seasoning for garlic salt, cayenne pepper, or even a sprinkle of lemon zest if you’re feeling zesty.
Mix it up your favorite ways—it’s your fish, your rules!

Here are 10 fun ideas to mix in or plop on top:

- Fresh Lemon Slices – Lay them on top before baking—fresh lemon juice vibes!
- Cayenne Pepper – Add a pinch—spicy like a pirate’s temper!

- Parmesan – Dust some on—cheesy fish, oh yeah!
- Lime Juice – Squirt this instead of lemon—zesty twist for fish tacos!
- Garlic Powder – Double up—because garlic’s the best part of any dish!
ANY SUBSTITUTIONS?

- Olive Oil – Use this instead of butter—healthier and still juicy!

- Sea Salt – Sub for regular salt—fancy like a sailor’s sprinkle!
- Honey – Replace light brown sugar—sweetens it up great ways!

Wrap leftovers in aluminum foil or pop them in an airtight container.
They’ll stay tasty in the fridge for 2–3 days—perfect for a next time snack!

The Spices are incredible in that recipe. I am so happy it worked out for you.
This recipe is great. But I did not add any brown sugar and I used olive oil and no butter.
I LOVE cooking fish in foil…little clean up. Served with brown rice.
I generally do not like fish, but my family does so I made this for them. I ended up trying it and it is absolutely delicious. Will be adding this to the rotation! Loved it!💕
Delicious & so simple…will make again!
Super good! Making it again tonight!
Wonderful seasoning. Fish flakes very nice. Maybe 21/2 minutes under the broiler.
