Pan Seared Chilean Sea Bass with Caper Tomato Butter
Have sea bass to cook? Lucky you! Try this easy Pan Seared Chilean Sea Bass recipe made entirely in one pan. One of my favorite fish recipes!
Pan Seared Chilean Seabass is truly a special dish. I prefer pan searing to cook most of our fish! Sauteed sea bass is definitely one of the lowest maintenance ways to prepare this kind of fish, but I prefer this method for the nice, golden crust and flaky texture that it provides.
Your traditional Chilean sea bass recipe will pair it with a lemon butter sauce, a basil pesto or a chimichurri. I’m not knocking any of these sauces. I love them all! But, I wanted to do something just a bit different.

The tomatoes in this sauce recipe provide a nice acidic balance to the rich, flaky fish. I love the bite and saltiness of the capers, and the butter soothes the acidity of the tomatoes so it’s not *too* much. The butter also gives your sauce a nice, velvety texture. I just love how the sauce pairs with the mild flavor of the sea bass. It’s perfection!
Because of the price of sea bass fillets, we save it for special occasions like date nights. It really is an expensive fish! But it is so, so delicious.

About Chilean Sea Bass
Chilean Sea Bass is a super desirable type of fish that is known for it’s delicate flavor and buttery texture. It might surprise you to find out that sea bass is not a bass (confusing, right)? It’s a type of Patagonian toothfish typically found in cold, deep waters of the Indian Oceans.
Chilean Sea Bass is a large, lengthy fish that can weight up to 200 pounds. It’s a mild white fish that has a high fat content and firm texture. Sea bass tastes super rich and moist, and because of the high oil content, it’s pretty hard to mess up! It’s delicious grilled, baked, broiled, or pan seared like in this delicious recipe!
I would be remiss to not mention that this type of fish is subject to overfishing, which can eventually lead to extinction. So, while it may be pricier, it’s very (VERY) important to purchase sea bass that is Marine Stewardship Council (MSC) certified for sustainable fishing practices. I purchase my sea bass through Sizzlefish to be certain that it’s been caught sustainably.
Don’t be afraid to ask the fish counter at your grocery store or fish market to see if their sea bass was sustainably caught!

Recipe Ingredient Substitutions and Addition Ideas
This is a versatile recipe that has a lot of potential for modifications! Here are a few ideas:
- Add 1-2 cloves of minced fresh garlic to the sauce when you add the capers, , or a tablespoon of fresh shallot!
- Add a splash of balsamic vinegar to the sauce for extra depth of flavor.
- Add a splash of fresh lemon juice or lemon zest to the sauce, or serve with lemon slices for extra color.
- If you don’t like capers, don’t add them! I understand that they are not everyone’s favorite.
- Can’t find Chilean sea bass fillets? Try cod, branzino or halibut in this recipe.
- Garnish with fresh parsley or rosemary.
Pan Seared Chilean Sea Bass Serving Suggestions
I love to serve this fish recipe with a bit of wild rice or polenta, and a fresh steamed green beans, chopped caprese salad, asparagus or brussels sprouts. It’s also a wonderful protein for salads.
For dessert, I think this beautiful fish deserves something a bit elevated like this passion fruit cake or blackberry custard pie!
Oh, and don’t forget a nice glass of wine! A dry white wine is the perfect pairing for the rich flavor of this fish.

Storing Leftover Sea Bass
I highly doubt you have any of this amazing sea bass leftover! But if you do, store it in an airtight container in the refrigerator for 2-3 days.
I prefer to gently reheat this fish in the air fryer or in a sauté pan for 1-2 minutes on low-medium heat.

Thank you, Evelyn! Glad you enjoyed it!
Amazing recipe! The instructions and notes were very helpful and the result was a high end restaurant quality dish. I used a generous pint of previously frozen garden cherry tomatoes instead of the canned diced ones. The sauce was wonderful with the crispy sea bass, blistered green beans and crusty bread.
I’m jealous of your garden tomatoes, Roger! Sounds so good, thank you for taking the time to let me know how it turned out.
Delicious, easy to make brown and don’t overcook. Used dark rum all I had delicious.
Thank you Joyce! Glad you enjoyed it.
