The Method for Garlic Butter Mahi Mahi

Now that you have your ingredients and gear ready, let’s get cooking! Follow these simple steps to create your Garlic Butter Mahi Mahi:
Step 1: Prepare the Mahi Mahi
Begin by patting the mahi mahi fillets dry with paper towels. This helps achieve a nice, seared exterior. Season both sides of the fillets generously with salt and ground black pepper.
Step 2: Heat the Olive Oil
In a large skillet, heat the olive oil over medium-high heat. Allow it to get hot but not smoking, as you want to sear the fish, not fry it.
Step 3: Cook the Mahi Mahi
Once the oil is hot, carefully place the mahi mahi fillets in the skillet. Cook for about 4-5 minutes on each side, or until the fish flakes easily with a fork and has a golden-brown crust. Remove the fillets from the skillet and set aside on a plate.
Step 4: Create the Garlic Butter Sauce
In the same skillet, reduce the heat to medium and add the minced garlic. Sauté for about 30 seconds, until fragrant but not browned. Immediately add the unsalted butter and let it melt, stirring to combine with the garlic.
Step 5: Add Lemon Juice and Parsley
Squeeze the juice from the two small lemons into the skillet, stirring to combine everything. Add the chopped fresh parsley and mix well.
Step 6: Return the Fish to the Pan
Carefully place the cooked mahi mahi fillets back into the skillet, spooning the garlic butter sauce over the top. Let it simmer for an additional minute or two to absorb the flavors.
Step 7: Serve and Enjoy
Transfer the mahi mahi to a serving platter, drizzling the remaining garlic butter sauce over the top. Garnish with extra parsley if desired and serve immediately, perhaps alongside steamed vegetables or a light salad.
Substitutions by Diet

If you need to make any substitutions for dietary preferences or restrictions, consider the following options:
- Butter substitute: Use vegan butter or coconut oil for a dairy-free version.
- Olive oil alternative: Avocado oil or grapeseed oil can be used for frying.
- Garlic: If you prefer a milder flavor, you can use garlic powder instead of fresh garlic.
- Parsley: Fresh basil or cilantro can be substituted for a different flavor profile.
Recipe Notes & Chef’s Commentary
Cooking mahi mahi is straightforward, but here are a few tips to ensure perfect results:
- Make sure your skillet is hot enough before adding the fish; this helps create a nice sear.
- Do not overcrowd the skillet; if cooking multiple fillets, work in batches to avoid steaming.
- You can adjust the amount of garlic to suit your taste—add more for a stronger flavor!
- Feel free to experiment with additional herbs and spices to personalize the dish.
Keep-It-Fresh Plan
This Garlic Butter Mahi Mahi is best enjoyed fresh, but if you have leftovers, store them in an airtight container in the refrigerator for up to 2 days. Reheat gently in the microwave or on the stovetop to avoid drying out the fish. If you want to prep ahead, you can marinate the fish in lemon juice, garlic, and herbs for up to an hour before cooking for even more flavor.
