Step‑by‑Step Instructions for Mahi Mahi Fish in Lemon Garlic Cream Sauce
Step 1: Prep the Mahi Mahi
Remove the Mahi Mahi fillets from the refrigerator 15-20 minutes prior to cooking to allow them to reach room temperature. Pat them dry with a paper towel, ensuring a good sear, and generously season both sides with a mixture of garlic powder, onion powder, salt, and paprika for added flavor.
Step 2: Cook the Mahi Mahi
In a large skillet, heat 1 tablespoon of olive oil and 1 tablespoon of butter over medium-high heat until shimmering. Once hot, carefully place the seasoned Mahi Mahi fillets in the skillet. Cook for about 4 minutes on one side until golden brown, then flip and cook for an additional 2-4 minutes until they reach an internal temperature of 137°F. Remove the fillets from the skillet and tent with foil to keep warm.
Step 3: Sauté Shallots and Garlic
In the same skillet, reduce the heat to medium and add the minced shallots. Sauté for about 2 minutes until they are translucent. Next, add the minced garlic and continue cooking for an additional minute. The shallots and garlic should be fragrant and just starting to brown, providing a flavorful base for the sauce in your Mahi Mahi Fish in Lemon Garlic Cream Sauce.
Step 4: Prepare the Cream Sauce
Stir in 1 cup of low sodium chicken broth, followed by ½ cup of heavy cream and the freshly squeezed lemon juice to enhance the sauce’s brightness. Season with salt, pepper, thyme, and parsley to your taste. Bring the mixture to a gentle simmer, allowing the flavors to meld for about 2 minutes, while stirring occasionally.
Step 5: Thicken the Sauce
To thicken the sauce, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water in a small bowl until smooth. Gradually add this mixture to the simmering sauce, stirring continuously until it thickens to your desired consistency—about 1-2 minutes. The creamy texture is a key element of the Mahi Mahi Fish in Lemon Garlic Cream Sauce.
Step 6: Combine and Serve
Return the cooked Mahi Mahi fillets to the skillet, gently coating them in the luscious cream sauce. Allow them to heat through for about 1 minute, ensuring they’re warm but not overcooked. Serve immediately, garnished with additional parsley if desired, and pair with your favorite side dishes for a complete meal.

Make Ahead Options
These Mahi Mahi Fish in Lemon Garlic Cream Sauce are perfect for meal prep enthusiasts! You can season and refrigerate the Mahi Mahi fillets up to 24 hours in advance, allowing the flavors to infuse while saving you time on busy weeknights. The creamy lemon garlic sauce can also be made ahead; simply prepare the sauce up to 3 days in advance and store it in an airtight container in the fridge. When you’re ready to serve, reheat the sauce gently over low heat, cook the fish for about 6-8 minutes, and then coat the Mahi Mahi in the creamy sauce for a restaurant-quality meal that’s just as delicious!
Expert Tips for Mahi Mahi Fish
Hot Pan: Ensure your skillet is hot before adding the Mahi Mahi; this helps achieve a beautiful golden crust and prevents sticking.

Perfect Sauce Consistency: Gradually add the cornstarch mixture to the sauce while stirring to prevent lumps, creating that silky smooth texture you desire in your Mahi Mahi fish in lemon garlic cream sauce.
Use Fresh Ingredients: Opt for fresh lemon juice and high-quality chicken broth; these elevate the flavors and overall quality of the dish.
Taste as You Go: Adjust seasoning throughout the cooking process, tasting to achieve the perfect balance between the rich cream and zesty lemon flavor.

Mahi Mahi Fish in Lemon Garlic Cream Sauce Recipe FAQs
How do I choose the best Mahi Mahi fillets?
Absolutely! When selecting Mahi Mahi, look for fillets that are firm and moist. They should have a pinkish-white color with no dark spots. Freshness is key, so if possible, buy from a trusted fishmonger or directly from the market. Skinless fillets, about 4-6 ounces each, will provide that perfect balance of tenderness and flavor for your Mahi Mahi Fish in Lemon Garlic Cream Sauce.
How should I store leftovers of this dish?
Very! Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. It’s best to keep the Mahi Mahi and sauce together because they meld beautifully in flavor. When you’re ready to enjoy them again, gently reheat in a skillet over low heat to maintain moisture and prevent overcooking.
Can I freeze Mahi Mahi with the sauce?
I often advise against it! While the cooked Mahi Mahi can be frozen for up to 3 months without the sauce, freezing the cream sauce can lead to separation. Wrap the fish tightly in plastic or foil to avoid freezer burn. When ready to eat, reheat the fish and whip up a fresh batch of sauce for the best flavor experience.
What if my sauce is too thick or too thin?
Don’t worry; it’s easily fixed! If the sauce is too thick, you can whisk in a bit of additional chicken broth or cream until you reach your desired consistency. If it’s too thin, mix a little more cornstarch (1 teaspoon) with cold water and stir it into the simmering sauce, cooking it for another minute until thickened.
Is this recipe suitable for individuals with dietary restrictions?
Certainly! This Mahi Mahi Fish in Lemon Garlic Cream Sauce can be made gluten-free by ensuring your chicken broth is free from gluten. It’s also low-carb since it features lean fish and can be paired with non-starchy veggies instead of traditional carbohydrates. Always double-check seasoning labels if allergies are a concern!
