Living in the Florida Keys, mahi mahi is one of the fish I cook most often. This collection includes my favorite ways to prepare it, from crispy pan-fried fillets to blackened mahi, tacos, and easy weeknight dinners.
What Is Mahi Mahi?
Mahi mahi, also called dolphinfish or dorado, is a firm white fish found in warm waters like the Florida Keys, Gulf of Mexico, and Caribbean. It has a mild flavor and a thick texture that works well for grilling, roasting, frying, and tacos.
In the Florida Keys, mahi mahi is one of the most popular local fish for fish sandwiches and grilled seafood platters.
How to Store Fresh Mahi Mahi
Refrigeration: When you bring fresh mahi mahi home, store it in the refrigerator right away. Place the fish on a plate or in a shallow dish, cover it loosely with plastic wrap, and keep it on the coldest shelf of the fridge, usually the bottom shelf toward the back. For best quality, use it within one day.
Keep It Cold While Traveling: If you're coming home from fishing, transport mahi mahi in a cooler with lots of ice to keep it cold until it reaches the refrigerator.
Freezing: If you don't plan to cook mahi mahi within a day, freezing is best. Pat the fish dry with paper towels. Wrap each piece tightly in plastic wrap, then place it in a freezer bag. Label with the date and use within one to two months. A vacuum sealer works well if you have one.
Top Tip:
If you bring home a fresh mahi mahi (also called dolphin), plan to eat it within a day for the best results. If that's not possible, pat the fillets dry and freeze them right away.
I like to freeze each fillet in its own bag so I can thaw only what I need.
Where to Get Fresh Fish in Florida
For the freshest fish in Florida, local markets and docks are usually a better bet than big grocery chains. Independent seafood markets often carry locally caught fish and can tell you exactly where it came from.
Some grocery stores, like Milam's Market, are known for good seafood counters and fresh turnover. Whole Foods Market sometimes carries local fish, but availability varies.
The Florida Department of Agriculture posts a list of Florida Seafood Markets, which is a good place to start if you're traveling around the state.
Seafood restaurants can also be a good source.
Places like The Fish House in Key Largo often sell fresh fish from their counters, including local favorites like mahi mahi, yellowtail, grouper, tripletail, yellowfin tuna, Key West pink shrimp, stone crab claws, and spiny lobster.
How To Pick Fresh Mahi at the Market
Look for mahi mahi fillets that are firm, moist, and pale pink to light beige. The flesh should look clean and slightly glossy, without dry edges, dark spots, or excess liquid in the package.
Fresh mahi mahi should smell mild and clean, not strongly fishy. Press the flesh lightly with your finger. It should spring back instead of leaving an indentation.
When buying frozen mahi mahi, choose fillets without heavy frost, ice crystals, or torn packaging. These can be signs that the fish thawed and was refrozen.
Best Seasonings for Mahi Mahi
Mahi mahi has a mild flavor and firm texture, so it works well with simple seafood seasonings and richer sauces.
- Old Bay seasoning
- Blackened seasoning
- Lemon pepper
- Garlic butter
- Key West Spice Company Southernmost Seasoning, a Florida Keys seasoning blend available at local fish markets and grocery stores throughout the Keys. It has a flavor similar to Old Bay and works well on fresh fish.

What Can I Use Instead of Mahi Mahi?
If you can't find mahi mahi, several other fish work well in these recipes. Hogfish, tripletail, snapper, and grouper are all good substitutes and are commonly found in the Florida Keys.
Keep in mind that thickness matters. Mahi is thicker than yellowtail, while grouper is usually thicker than mahi. Thicker fillets will need a few extra minutes of cooking time. The fish is done when it flakes easily with a fork. If it still feels firm or tight, give it another minute or two.
When possible, buy the freshest fish available. Whether you're cooking what you caught or shopping at a local market, fresh fish always gives the best results.
I recently had mahi mahi served with sliced avocado and pico de gallo at Jimmy Johnson's Big Chill Restaurant and Bar in Key Largo. It's a simple combination that works every time.
The Best Sides For Mahi Mahi
Mahi mahi pairs best with simple sides. Add a starch like rice or potatoes, a green vegetable, and something fresh like a salad or salsa. Keep it light and fresh!
