As someone who cooks dinner most nights, I find seafood dishes to be my favorite.

Over the past few years, I’ve followed a more pescatarian style of eating, so fish has become a big part of my meals. I like to try new things and recently have fallen in love with cooking Chilean sea bass. While it’s a popular choice at fine dining restaurants or elegant events, making it at home is SO easy and tastes just as good…if not better!

What is Chilean Sea Bass?

If you aren’t familiar with this Chilean sea bass (Patagonian toothfish), it is a white fish that is found in waters surrounding Chile (as the name suggests). You may be familiar with traditional sea bass, but this one is a little different.

It is a popular choice for those who don’t eat seafood regularly. Its texture is silky and buttery and has a very mild flavor. We love to cook this fish because it has no fishy flavor or aftertaste– perfect for those who are new to seafood.

Why I love this recipe

  • Quick and easy. Cooking this fish comes together in less than 10 minutes, and it needs just four main ingredients.
  • Restaurant style. This is the best recipe that really allows the fish to shine, and a secret trick guarantees perfectly cooked fish every single time (hint: it’s ONLY butter… no oil).
  • Multiple cooking methods. I like to pan-sear the fish, but I’ve also included tested options on the grill and in the oven.

Ingredients needed

  • Chilean sea bass fillets. Skinless sea bass fillets are preferred, as both sides of the fish cook evenly and consistently. Because of the slightly higher price tag, I prefer to get the fillets from a fishmonger over a grocery store.
  • Kosher salt and black pepper. To taste. 
  • Unsalted butter. Pan-frying white fish fillets in butter takes the flavor of the dish to another level. It also cooks the fish perfectly every single time. Olive oil
  • Garlic. Freshly minced garlic, not the jarred kind! 
  • Lemon. Fresh lemons to squeeze over the freshly cooked fish. 

Choosing the best sea bass

Like other fish and seafood out there, choosing the best sea bass will affect the overall flavor and texture. 

  • Ensure the fish has no strong odors and has a mild and sweet fragrance. If there is any fishy smell, it’s usually several days old and not freshly caught. 
  • There should be no dry spots on the fillets, and they look firm and moist. 
  • After purchasing your sea bass, take it directly home and cook it that day.
  • Never freeze the fresh filets, as once thawed, they won’t cook or taste the same. 

How to cook Chilean sea bass

I’ve included step-by-step photos below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the recipe card at the bottom of this post.

Step 1- Prepare the fish. Start by pat drying the fish filets with paper towel, before sprinkling one side on each filet with salt and pepper.

Step 2- Cook the fish. Next, add the butter into a non-stick pan or cast iron skillet and place it over medium high heat. Once hot, add the garlic and cook for a minute, until fragrant. Add the sea bass and cook the fish for 2-3 minutes, flip, and cook for another two minutes.

Step 3- Garnish and serve. Now, remove the cooked fish from the pan/skillet and drizzle with lemon butter sauce, garlic, and squeeze some fresh lemon juice.

Alternative cooking methods

I find pan-searing Chilean sea bass to be the best way to cook the fish. This really allows the natural sweet flavors to stand out and guarantees the buttery and flaky texture it is famous for. However, I’ve also tested it on the grill and in the oven, so you have options.

Grill method: Clean the grill grates then grease with olive oil or butter. Once hot, place the Chilean sea bass fillets on top and grill for 2-3 minutes, flip, and cook for another 2 minutes.

Oven method: Preheat the oven to 180C/350F. Line a baking dish with tin foil and grease with olive oil or butter. Place the fish fillets on top and bake for 20 minutes.

Arman’s recipe tips

  • The cooking time may vary depending on the size of your sea bass filets. My fillets were around 6 ounces, so the cooking time instructed was perfect for them. You may need to cook a little longer if your fillets are bigger. Also, always choose filets of a similar weight so they all cook evenly. You can also check the internal temperature using a meat thermometer. Fish that is ready to eat should reach an internal temp of at least 145F.
  • Frozen fish fillets will work, but make sure you thaw the sea bass completely and mop up any excess moisture.
  • As mentioned earlier, I prefer skin-on fillets because they create a gorgeous sear, but skinless fillets can be used too. Just have a little extra butter on hand to make sure there is no sticking.
  • I purposely kept the seasonings VERY sparse to really let the flavor of the fish shine (hello, it’s a fancy fish!). If you do want to jazz it up, try a simple marinade using soy and ginger or a fun Asian sauce, like eel sauce or potsticker sauce. You can also use fresh herbs like fresh parsley, lemon zest, and smoked paprika.

Storage instructions

To store: Leftover sea bass can be stored in the refrigerator in an airtight container for up to three days. 

To freeze: Place the cooked and cooled bass in a sealable container and store it in the freezer for up to two months. The fish must be thawed completely before reheating. 

Reheating: Either microwave the fish for 30-40 seconds or reheat in a non-stick pan until crispy around the edges.

    OMG, this recipe was the easiest and the most delicious! My sister had never had sea bass before so I made it for both of us. I did get it without the skin and it was absolutely amazing! If you haven’t tried this, please use this recipe, you won’t regret it, the absolute best!

    Perfection cooking on the pan with butter! Great crust on the fish while the inside was light and succulent. My pieces were about 7 ounces and I had to sear them for 5 minutes and three minutes. Will make again and again!

    Just outstanding. I basically cut the ingredients in half for one inch thick filet of Sea Bass that weighed 12-13oz. I mashed the minced garlic into the softened butter and coated the skins side for the second part. Cooked it in an iron pan for about 14 minutes. Absolute, perfection.

  5. Just made this recipe and it was so delicious! My pieces were bigger so they cooked for a little longer. Thanks for sharing.
