Is sea bass the same as Chilean sea bass?

Sea bass and Chilean sea bass are not the same thing. Sea bass is a general name used for many different fish from various species.

Chilean Sea Bass is a deep water fish, found in southern ocean waters near and around Antartica. It’s rich, buttery flavor and moist meat simply melts in your mouth, making it one of the most sought-after seafood choices.

How to cook Chilean sea bass

Chilean sea bass can be grilled, pan seared or baked in the oven. I prefer a combination of pan searing the sea bass, then finishing it in the oven. This gives the outside a nice crust, while the inside stays moist and delicious.

Follow these four simple steps to cook Chilean sea bass perfect every time!

  1. Make sure the pan you’re searing the sea bass in is hot before adding the fish. This ensures the sea bass gets a nice crust on the outside. Season the sea bass only with salt and pepper after adding it to the pan.
  2. Cook the sea bass on the stove for 2 minutes per side, this will ensure the fish has a nice sear on the outside, but doesn’t overcook on the inside.
  3. Bake in the oven at 400°F for 10 minutes. This time and temperature will allow the sea bass to cook through, without overcooking. You definitely DO NOT want to overcook Chilean sea bass, as that will ruin the moist, meaty texture of the fish.
  4. Add sauce to the sea bass after it’s cooked. Adding the sauce at the end will allow it to melt over the sea bass, while still allowing the buttery flavor of the sea bass to shine through.
    • Quick Tip! Not a fan of pesto or looking for a dairy free, nut free option? Try Chimichurri Sauce on top instead!

What side dishes go with it?

Chilean sea bass is a rich, buttery fish that pairs perfectly with roasted vegetables, risotto or a simple green salad. In this recipe, I roast cherry tomatoes right in the pan with the sea bass.

For serving, I recommend adding cooked zucchini noodles for a healthy, low carb meal or mushroom risotto for something more decadent.

Baked Chilean Sea Bass with Pesto

Make perfectly cooked chilean sea bass every time by searing it on the stove, then baking it in the oven. Top the sea bass with pesto for an easy, flavorful meal!



  • Preheat the oven to 400°F.
  • Heat 1 tbsp olive oil in a large cast iron skillet, or oven-safe skillet, over medium high heat.
  • Once the oil is hot, add the sea bass to the skillet, sprinkle with approximately ⅛ tsp salt and ⅛ tsp pepper.
  • Add the tomatoes to the skillet, drizzle the remaining olive oil over the tomatoes.
  • Cook for 2 minutes, then flip the fish.
  • Sprinkle the remaining salt and pepper over the other side of the sea bass and the cherry tomatoes, cook for 2 minutes.
  • Transfer to the oven and cook for an additional 10 minutes.
  • Remove from the oven, place each sea bass on a plate with cherry tomatoes, spoon ½ tbsp pesto over each piece of sea bass.


  • For a dairy free, nut free recipe, use Chimichurri Sauce instead of pesto, on top of the sea bass.
