This incredibly flavored pan seared Chilean sea bass is served with Mediterranean-style vegetables and is finished with fresh basil. You won’t believe how fast this restaurant-style recipe comes together.
Chilean Sea Bass
Chilean sea bass is caught in deep waters in and around southern oceans near Antarctica. It is a buttery, firm, mildly sweet, melt-in-your-mouth fish that pairs with just about anything. It is snow-white in color and can be eaten with or without the skin.
You can grill, broil, bake, pan-sear, or poach it. Chilean sea bass is a bit of an overfished species and is often very expensive.
Ingredients You’ll Need to Make It
- Oil – Any neutral flavored oil will work.
- Butter – unsalted butter helps to brown the fish, add flavor, and assists on releasing it from the pan.
- Sea Bass – Use fresh, skin on sea bass for this recipe.
- Tomatoes – I prefer to use cherry tomatoes as they are decent all year long.
- Peppers – Use roasted red peppers for this recipe.
- Olives – I like a combination of kalamata and Frescatrano olives.
- Shallots – Small diced shallots will help add a lot of flavors.
- Garlic – Finely diced garlic will take the sauce to the next level.
- Potatoes – I use baby Yukon gold and red potatoes, but any baby potatoes will do.
- Basil – Finish the sauce with fresh basil, but if it is not available then use half the amount of dry.
- White Wine – You can use chardonnay, pinot grigio, or sauvignon blanc, and hit will help deglaze the pan.

Deglaze with white wine and cook for 2 minutes, season with salt and pepper, and fold in fresh basil. Set aside.
Pat the sea bass down with paper towels and then season both sides with salt and pepper.
Add some oil to a large frying pan and heat over high heat until it begins to lightly smoke.
Place in the sea bass, turn the heat down to medium to medium-high, add in some butter and cook for 5 to 6 minutes per side or until golden brown and cooked throughout.
