Grilled Chilean Sea Bass

This grilled Chilean sea bass recipe is buttery, flaky, and full of rich flavor. It takes nothing more than 4 ingredients, plus an optional fresh mango salsa, to make this fish impressive!

Why this recipe works

Grilled Chilean sea bass is known for its buttery rich flavor and melt-in-your-mouth texture. The natural oils in Chilean sea bass keep the fish nice and moist, whether it’s grilled, pan-seared, or baked. In fact, it’s quite hard to overcook it thanks to those very oils. It comes out flaky, delicate, and full of moisture every time.

Because it’s so flavorful on its own, it really doesn’t need any extravagant seasonings or rubs. I personally love topping it with vibrant mango salsa, but a pat of melted butter along with a few shakes of Old Bay and garlic salt adds just enough oomph to complement the fish without overpowering it.

Ingredient Info and Substitution Suggestions

FISH – We used the thickest part of the fish for this recipe. When purchasing Chilean sea bass you may end up with the end that is closer to the tail, which isn’t as thick as the center cut. It all tastes good, but we like the thicker pieces. This is why it’s important to use a meat thermometer to check for doneness rather than relying on minutes cooked.

SEASONING – Chilean sea bass is flavorful on its own, so we use minimal seasonings in this recipe. While you can add or remove whatever flavorings you like, remember that this fish on its own is delicious and has a wonderful buttery texture. It doesn’t need much more than the sea has given us!

3. Season all sides of the filets with Old Bay and garlic salt.
4. Place filets on the grill. Allow them to cook for a couple of minutes so they start to develop a crust.

Serving Suggestions

Chilean sea bass is a mild fish, which means you can pair it with a ton of different sides. Optionally serve it over or alongside a bed of white rice with fresh mango salsa, pineapple salsa, or herbaceous chimichurri on top. Aside from rice, it’s great with mashed potatoes or quinoa with a medley of roasted vegetables.

This recipe is by far one of my favorites. It’s rich, delicate, and full of flavor, no matter how you serve it. I hope you enjoy it as much as we did!

Before You Begin

• We used the thickest part of the fish for this recipe. When purchasing Chilean sea bass you may end up with the end that is closer to the tail, which isn’t as thick as the center cut. It all tastes good, but we like the thicker pieces. This is why it’s important to use a meat thermometer to check for doneness rather than relying on minutes cooked.
• Chilean sea bass is best enjoyed at a temperature of 145F (62C). Use a meat thermometer inserted into the thickest portion of the fish to gauge the temperature. I highly recommend using an instant read thermometer, as relying on cook time alone can vary greatly depending on how thick or thin your cut of fish is.

• Preheat grill to 375F, or enough so that the grates get nice and hot.

The recipes on this blog are tested with a conventional gas oven and gas stovetop. It’s important to note that some ovens, especially as they age, can cook and bake inconsistently. Using an inexpensive oven thermometer can assure you that your oven is truly heating to the proper temperature. If you use a toaster oven or countertop oven, please keep in mind that they may not distribute heat the same as a conventional full sized oven and you may need to adjust your cooking/baking times. In the case of recipes made with a pressure cooker, air fryer, slow cooker, or other appliance, a link to the appliances we use is listed within each respective recipe. For baking recipes where measurements are given by weight, please note that results may not be the same if cups are used instead, and we can’t guarantee success with that method.
