Restaurant Quality Fish at Home

I grew up in a family that often dished up fish for dinner. Any given weeknight, we would sit down to a meal that included freshly cooked fish. My parents served up all varieties of fish, from whole fish to fish fillets. They used all methods of cooking with their fish recipes, from whole branzino fish to pan fried cod.

Though there are a myriad of ways to cook up delicious fish, such as our Sheet Pan Lemon Salmon and Seared Halibut– this easy mahi mahi fish recipe is perfect for anyone to make. It only takes about 20 minutes, it’s super tender, and incredibly tasty. People keep telling me they can’t believe they made this restaurant-quality mahi mahi dish by themselves. You can, too.

Key Ingredients

• Olive Oil: we use olive oil for best flavor and a healthy boost.
• Mahi Mahi: Look for fish fillets that are 1-inch thick throughout the entire fillet, and roughly 4oz per fillet. Frozen or fresh fillets are fine.
• Garlic: Plenty of freshly minced garlic is called for. Don’t skimp on the garlic.
• Lemon: Grab one fresh lemon and zest the peel; then squeeze 1 TB of tangy juice from it. Bottled lemon juice isn’t the same, so use fresh lemons.
• Butter: I prefer to use salted pure butter, but feel free to use unsalted if you like as long as it’s real butter.
• Herbs: For freshly chopped herbs, choose from chives or parsley…or both.

Step-By-Step Instructions

We use the stovetop-to-oven method of cooking here, like we do with this trusty lemon garlic swordfish, which yields a nicely browned exterior yet tender, flaky center.

1. Lemon Garlic Mixture(can be made ahead) – in a small pan, combine all Lemon Garlic Mixture ingredients and stir to fully combine. Keep warm.
2. Pat-dryall excess moisture from the fish fillets with paper towels. This step is important, so be sure to pat off as much moisture as you can. Evenly sprinkle both sides of fillets with pinches of kosher salt and freshly ground black pepper.

3. In a large oven-proof pan, heat the olive oil over high heat. Once oil issizzling hotadd the fish fillets to pan and let cook until browned on one side, about 3 minutes –do not move fish around. Carefully flip fish fillets over to the other side, turn stove burner off, and immediately transfer pan into already-hot oven.
4. Roast fish at 400F about 5 minutes or just until the top is golden and center is just cooked through. Take carenot to overcook.

5. Immediately turn heat offand pour warm lemon butter sauce over the cooked fish.

Pro Tips for Success

Here are some of our most helpful tips for cooking mahi mahi, which applies to many other fish as well:

• Get either super fresh or quick-frozen, high quality mahi mahi. Wild is best and will provide best flavor.
• Be sure fillets are at least 1-inch thickness. If your portions are thin or too small, they’ll tend to overcook and the seasoning proportions will be off.
• Always pat dry excess moisture from the fish; this step is super important, as it affects how well your fish will brown.
• Use a large, oven-proof pan that heats evenly.
• Your cooking oil needs to be very hot [like, sizzling] before adding the fish. This allows for quick and even browning of exterior.
• Once fish is in pan, do not keep moving it around. Let it sit and brown for 3 minutes. It helps to have a large splatter guard. I use mine often whenever pan-frying foods.
• Preheat oven ahead of time so that it’s nice and hot when you transfer the mahi mahi directly from stovetop to oven. After 5 minutes in the oven, it’s done.
• Bonus Tip: sauce can be prepared ahead of time, covered, and chilled until you’re ready to warm it up for serving. It’s a great sauce to have on hand.
