How to Make Garlicky Lemon Mahi-Mahi
-
Prep Tools: Gather your fish spatula and a sturdy cast-iron or nonstick skillet. Having the right tools will make handling the mahi-mahi easier and help achieve that perfect sear.
-
Cook Fish: Heat 1 tablespoon of butter and 1 tablespoon of olive oil in your skillet until shimmering. Season the mahi-mahi fillets with kosher salt and freshly ground black pepper, then place them skin-side down. Cook for 4-5 minutes until the skin is crispy and golden, then flip them over and continue cooking for another 4 minutes. Transfer the fish carefully to a plate and set aside.
-
Cook Asparagus: In the same skillet, add another tablespoon of olive oil, then toss in the asparagus. Season with a pinch of salt and pepper, and cook for about 2-4 minutes until bright green and crisp-tender. Once done, remove the asparagus and place it alongside the mahi-mahi on the plate.
-
Prepare Sauce: Lower the heat on the skillet, add the remaining tablespoon of butter, and let it melt. Stir in the minced garlic and crushed red pepper flakes, letting the mixture become fragrant—about 1 minute. Squeeze in the juice of one lemon and add the zest, scraping up any flavorful bits stuck to the pan. Layer the lemon slices into the sauce, return the fish and asparagus back to the skillet, and spoon that delicious sauce over everything.
-
Serve and Garnish: Sprinkle fresh parsley over the dish for a burst of flavor and color, then serve immediately while everything is hot and vibrant. Enjoy the delightful combination of flavors!
Optional: For a splash of color, add lemon wedges on the side for extra brightness!

Garlicky Lemon Mahi-Mahi Recipe FAQs
How do I choose the best mahi-mahi for this recipe?
Absolutely! When selecting mahi-mahi, look for firm fillets that are bright in color, with minimal brown or dark spots. Fresh mahi-mahi should have a mild, sweet ocean smell. If you’re purchasing frozen, ensure it has been frozen properly and is sold at a consistent, cold temperature.
What’s the best way to store leftovers?
Great question! Store any leftover Garlicky Lemon Mahi-Mahi in an airtight container in the refrigerator for up to 2 days. This keeps the dish fresh while retaining the delicious flavors. Be sure to reheat gently on the stovetop for the best results!
Can I freeze Garlicky Lemon Mahi-Mahi?
Certainly! To freeze, wrap the cooked mahi-mahi tightly in plastic wrap, then in aluminum foil to create a barrier against freezer burn. It can be stored in the freezer for up to 3 months. When you’re ready to enjoy, defrost in the refrigerator overnight and reheat in a skillet over low heat.
What can I do if the fish is dry after cooking?
If you find your mahi-mahi turned out dry, don’t worry! A splash of broth or some fresh lemon juice can help moisten it up. If that doesn’t do the trick, consider serving it with a creamy sauce or over a bed of rice to add moisture and flavor back into the dish.
Are there any dietary considerations for this recipe?
Very! If you’re serving this dish to guests or family members with food allergies, it’s important to highlight that this recipe contains fish, dairy (butter), and can be made gluten-free easily. For a dairy-free option, use olive oil instead of butter, and keep an eye on the seasonings for any hidden allergens.
What can I substitute for asparagus?
The more the merrier! If you’re not an asparagus fan or it’s out of season, feel free to use green beans or broccoli instead. Both alternatives provide that nice crunch you want alongside the flaky mahi-mahi, and they can be cooked in the same manner to keep the preparation simple.
