Step‑by‑Step Instructions for Mahi Mahi Fish in Lemon Garlic Cream Sauce
Step 1: Prepare the Fish
Remove your mahi mahi fillets from the refrigerator and let them rest at room temperature for about 15-20 minutes. This helps ensure even cooking. While waiting, you can prep your other ingredients, which keeps everything flowing smoothly once you start cooking.
Step 2: Pat and Season
Once the mahi mahi fillets have rested, pat them dry with paper towels. This step promotes an excellent sear when cooking. Next, season the fillets with salt and pepper, and lightly dredge them in flour to enhance the crust when pan-searing.
Step 3: Heat the Pan
In a large, heavy-bottomed skillet, heat a tablespoon of olive oil and a tablespoon of butter over medium-high heat. Wait until the oil is shimmering and the butter has melted, creating a lovely base for your mahi mahi. This combination ensures your fish gets beautifully crispy.
Step 4: Cook the Mahi Mahi
Gently add the seasoned mahi mahi fillets to the hot skillet, taking care not to overcrowd the pan. Let them cook undisturbed for about 4 minutes, allowing a golden crust to form. Then, flip the fillets carefully and cook for an additional 2-4 minutes until their internal temperature reaches 137°F and they are opaque throughout.
Step 5: Keep the Fish Warm
Once the mahi mahi is perfectly cooked, remove the fillets from the skillet and tent them with aluminum foil to keep warm. This step is essential as it ensures the fish remains flaky and moist while you prepare the flavorful lemon garlic cream sauce.
Step 6: Sauté Aromatics
In the same skillet, lower the heat slightly and add 3 tablespoons of minced shallots and 3-4 cloves of minced garlic. Sauté for about 1-2 minutes or until fragrant, taking care not to let the garlic burn. This aromatic base adds depth to your sauce.
Step 7: Create the Sauce Base
Whisk in a cup of low-sodium chicken broth along with dried thyme, dried parsley, and the freshly squeezed lemon juice. Let this mixture come to a gentle simmer for about 3-4 minutes, allowing the flavors to meld beautifully.
Step 8: Thicken the Sauce
Stir in ½ cup of heavy cream along with a teaspoon of cornstarch, whisking until fully combined. Simmer the sauce for another 3-5 minutes until it thickens slightly, adjusting seasoning to taste with more salt and pepper if needed.
Step 9: Coat the Mahi Mahi
Return the cooked mahi mahi to the skillet, gently coating each piece with the luscious lemon garlic cream sauce. Let it simmer for just a minute to warm the fish through, allowing the flavors to intertwine before serving.
Step 10: Serve and Enjoy
Carefully plate the mahi mahi fillets, drizzling additional lemon garlic cream sauce over the top. This dish pairs wonderfully with a side of rice, mashed potatoes, or fresh salad, creating a truly delightful meal that’s sure to impress!

Storage Tips for Mahi Mahi Fish in Lemon Garlic Cream Sauce
Fridge: Store any leftover Mahi Mahi in an airtight container for up to 3-4 days. To enjoy it at its best, consume it within this timeframe.
Freezer: Freezing the fish is not recommended as it may compromise its texture. However, the sauce can be frozen in a separate airtight container for up to 2 months.
Reheating: When reheating the Mahi Mahi, do so gently in a skillet over low heat to maintain the fish’s tenderness. If reheating the sauce, stir constantly until warmed through to keep it smooth.
Serving Suggestions: Consider serving the reheated Mahi Mahi with fresh sides or a vibrant salad to refresh the dish after storage.
Make Ahead Options

You can season and dredge the mahi mahi fillets up to 24 hours in advance, wrapping them tightly in plastic wrap to keep them fresh and ready to cook.

To maintain quality, reheat the sauce gently on the stove while stirring, then return the cooked fish to the sauce for a quick warm-up before serving. This way, you’ll enjoy a restaurant-quality dish with minimal effort on busy weeknights!

Expert Tips for Mahi Mahi Fish in Lemon Garlic Cream Sauce
-
Preheat the Pan: Always ensure your pan is hot before adding the fish. This aids in achieving that perfect golden crust and prevents sticking.
-
Don’t Overcrowd the Pan: Cooking too many fillets at once can lower the pan’s temperature, resulting in steaming rather than searing. Cook in batches if necessary.
-
Check Internal Temperature: Use a meat thermometer to monitor the mahi mahi’s internal temperature, which should reach 137°F for optimal tenderness and flavor.
-
Choose Fresh Ingredients: Fresh lemons and garlic elevate the sauce. Always opt for freshly squeezed lemon juice and fresh garlic rather than bottled or powdered versions.
-
Adjust Sauce Thickness: Monitor the sauce as it simmers; add more cornstarch if you prefer a thicker consistency, but be cautious not to make it too heavy.
-

Mahi Mahi Fish in Lemon Garlic Cream Sauce Recipe FAQs
How do I choose ripe Mahi Mahi fillets?
Absolutely! Look for Mahi Mahi fillets that are moist, with a translucent appearance and a fresh ocean smell. Avoid fillets with dark spots all over or a dull color, as these are signs of age. If possible, purchase them from reputable fishmongers who can attest to their freshness.
What is the best way to store leftovers?
For optimal freshness, store any leftover Mahi Mahi in an airtight container in the fridge for up to 3-4 days. To reheat, gently warm it in a skillet over low heat to maintain its wonderful tenderness. Remember, it’s better to consume it within this timeframe to enjoy the best flavors.
Can I freeze the sauce from the dish?
Yes, you can freeze the lemon garlic cream sauce! Transfer it to an airtight container and place it in the freezer for up to 2 months. When you’re ready to use it, thaw it in the fridge overnight. Reheat gently on the stovetop, stirring constantly until warm and smooth. I often do this for meal prep!
What should I do if the sauce isn’t thickening?
If your sauce isn’t thickening as you’d like, don’t worry! Simply whisk together an additional teaspoon of cornstarch with a tablespoon of cold water to create a slurry, then stir it into your simmering sauce. Allow it to cook for a few more minutes until it reaches your desired consistency.
Can I use this recipe for my pet?
While this Mahi Mahi dish is great for humans, it’s essential to avoid the butter, garlic, and heavy cream when considering it for pets. Instead, you can lightly steam plain Mahi Mahi fillets without any seasoning and serve small portions as a treat. Always consult with your veterinarian before introducing new foods.
Are there any dietary alternatives for this recipe?
Very! If you’re looking for substitutes, you can easily modify this recipe to fit dietary needs. Instead of heavy cream, consider using coconut milk for a dairy-free version. For a lighter sauce, simply omit the cream entirely and add more chicken broth. Gluten-free flour can replace regular flour for dredging, ensuring everyone can enjoy this tasty Mahi Mahi Fish in Lemon Garlic Cream Sauce!
