Benefits of Baking Fish

Baking fish in the oven has several advantages over other cooking methods

  • It’s easy. Simply prepare the fish, pop it in the oven and let it bake until flaky and cooked through. No need to constantly monitor it like when pan frying or grilling.

  • It locks in moisture. The hot, dry heat of the oven gently cooks the fish while sealing in the natural juices. The result is tender, moist fish.

  • It enhances flavor. Baking allows fish to absorb any extra flavors from spices, herbs or sauces baked onto the fish.

  • It cooks evenly. No need to worry about over or undercooked sections. The heat circulates evenly around the fish to cook it at the same rate.

  • It’s healthy. Baking is a low fat way to cook fish without needing to add much, if any, extra oil or butter.

How to Choose Mahi Mahi for Baking

When buying mahi mahi for baking, keep these tips in mind:

  • Look for fillets that are 1 to 1 1/2 inches thick. Thicker cuts hold up better in the oven.

  • Make sure the fish looks moist and shiny, not dried out. Aim for translucent looking flesh.

  • Smell the fish. It should smell mild, sweet and like the ocean. Any fishy or strong odor means it’s past its prime.

  • Fillets are often sold with or without skin. With skin helps keep it moist but skinless is easier to eat.

  • Farm-raised or wild caught mahi mahi will both work well. Wild caught has a richer flavor.

  • Purchase fillets the day you plan to cook them for optimal freshness.

How to Bake Mahi Mahi in Foil Packets

Baking fish en papillote style in sealed foil packets locks in moisture and infuses the mild fish with loads of flavor. Follow these steps:

  • Cut 4 large sheets of heavy duty foil. Place a fillet in the center of each piece.

  • Top fish with thin slices of lemon, lime or orange. Add other flavorings like minced garlic, julienned ginger, thinly sliced chilies, chopped herbs or a drizzle of soy sauce.

  • Seal the foil tightly around the fish and place packets on a baking sheet.

  • Bake at 425°F for 12-15 minutes until the fish is cooked through.

  • Carefully open the packets, slide the fillets onto plates and spoon over any accumulated juices from the packet.

This steaming method effectively poaches the fish delicately in its own steam and juices inside the sealed foil. It infuses bright citrus and other flavors right into the flesh.

Tips for Baked Mahi Mahi Success

Follow these simple tips to ensure your oven-baked mahi mahi turns out moist and full of flavor every time:

  • Pat fillets very dry before baking. Excess moisture causes it to steam instead of lightly brown.

  • Brush fillets with oil or melted butter to help conduct heat evenly and prevent drying out.

  • Bake in a 400°F oven for best results. Higher temps overcook before the center finishes.

  • Bake thin fillets 8-10 minutes, and thicker cuts 12-15 minutes until opaque and flaky.

  • Let it rest 3-5 minutes after baking to allow juices to reabsorb before serving.

  • Check for doneness by inserting a fork into the thickest part. It should flake and separate easily when done.

  • Prevent overcooking by removing smaller pieces first if baking fillets of varying thicknesses.

  • Add any toppings like herbs, crumbs or stuffing midway through baking so they don’t burn.

  • Pair with citrus, salsa, chutney or sauces to complement the mild flavor.

My Take On Baked Mahi Mahi

It only takes a few simple ingredients for this easy baked mahi mahi recipe to make juicy baked fish fillets that taste great.

Just the seasoning makes it impossible to resist, and my easy cooking method lets the fish’s mild flavor really shine. Baking the fish gives it a slightly crisp outside and flaky and tender inside thats just perfect.

This recipe tastes just like something you’d get at a restaurant, so I love making it when I have people over. I always make a side dish to go with it because it’s so easy to make, like these keto cheddar bay biscuits.

How To Store and Reheat Leftovers

In the fridge: Put any leftovers in a container that won’t let air in and put it in the fridge for up to three to four days.

Let the fish cool completely before putting it in a freezer-safe container. This will help it last longer in the freezer for up to three months.

I like to put the fish on a baking sheet lined with parchment paper and bake it at 275°F for 10 to 12 minutes to warm it up again. It also is pretty delicious just eaten cold.

The fish should be at least 137°F on the inside, and it should flake easily when you touch it with a fork.
