Step‑by‑Step Instructions for Mahi Mahi Fish in Lemon Garlic Cream Sauce
Step 1: Prepare the Fish
Remove the mahi mahi fillets from the refrigerator 15-20 minutes before cooking to ensure they cook evenly. Pat each fillet dry with paper towels, ensuring that moisture is removed to help the spice rub adhere better. This step is crucial for achieving that perfect sear.
Step 2: Make the Spice Rub
In a small bowl, combine flour, garlic powder, onion powder, paprika, salt, and pepper. Mix well to ensure an even distribution of spice. Dredge each mahi mahi fillet in this mixture, coating both sides thoroughly to enhance flavor and create a crispy texture during cooking.
Step 3: Heat the Pan
Place a large, heavy-bottom skillet over medium-high heat and add a tablespoon of oil and a pat of butter. Allow the oil to become shimmering and the butter to melt completely; this combination provides flavor and helps achieve a golden crust on the mahi mahi.
Step 4: Cook the Mahi Mahi
Carefully place the coated mahi mahi fillets into the hot pan, ensuring they are spaced apart to avoid overcrowding. Sear the fillets for about 4 minutes on one side until they turn a golden brown. Flip the fish and continue cooking for an additional 2-4 minutes, until the flesh turns opaque and the internal temperature reaches 137°F.
Step 5: Prepare the Sauce
Once the mahi mahi is cooked, remove it from the pan and tent with foil to keep warm. In the same skillet, add shallots and sauté until they become soft and translucent. Then, add minced garlic and cook for about 30 seconds until fragrant, infusing the residual flavors into your sauce.
Step 6: Create the Cream Sauce
Whisk in chicken broth while bringing the mixture to a simmer. Incorporate heavy cream, cornstarch, lemon juice, and dried thyme; stir continuously until the sauce thickens and blends well. This creamy lemon garlic sauce is what will elevate your mahi mahi, adding richness and tang.
Step 7: Combine and Serve
Return the cooked mahi mahi fillets to the pan, allowing them to coat in the luscious sauce. Let them sit for a minute to absorb the flavors before serving. The result is a beautiful dish of mahi mahi fish in lemon garlic cream sauce, ready to impress at your dinner table.
