Chilean Sea Bass Nutrition

This fish is packed with protein and is a great source of omega-3 fatty acids, which may provide an anti-inflammatory effect for people with IBD.

Chilean Sea Bass Nutrition Facts

Per 3oz serving of sea bass you will get:

  • 18 grams of protein
  • 2 grams of EPA + DHA omega-3 fatty acids
  • 310 milligrams of potassium (9% of recommended daily value)

  • 0 grams of fiber

Mercury in Chilean Sea Bass

However, please note that Chilean Sea Bass has moderately high levels of mercury. The Environmental Defense Fund recommends adults consume only two portions of Chilean sea bass each month and children only eat one portion each month due to the concerning levels of mercury.

When possible, look for the blue eco-label of the Marine Stewardship Council (MSC) for certified sustainable Chilean seabass products.

Things to Consider When Buying Chilean Sea Bass

Here are tips for buying eco-conscious Chilean sea bass:

  • Eco-Best: Look for options from Heard and McDonald, the Falkland, or Macquarie.
  • Eco-OK: Options from the Ross Sea, South Georgia, or Kerguelen.

What is the Best Cooking Technique for Sea Bass?

I prefer to pan-sear sea bass as a simple but delicious cooking method. It only takes a few minutes and creates a great texture when cooking.

How to Pan Sear Sea Bass

Place fish skin side down on hot pan.Once your fish goes down in the pan don’t move it until it is time to flip. This fish is very tender and flaky, so moving it around might break the fillet in half and lose it’s visual appeal.

Cook for approximately 2-3 more minutes. When it’s done, the fillet will be white with reduced transparency and will flake easily with a fork.

Should You Keep the Skin on When Cooking?

For this pan-seared recipe, leaving the skin on the fillets during cooking result in a perfect crispy and textural contrast to the soft meat of the fish. The cooked fish can be eaten with or without the skin. If preferred, serve fish without skin by removing the skin after cooking. Done in a hot pan, it generally separates from the flesh easily.

Prefer an Alternative to Chilean Sea Bass?

Sablefish offers the same “silken richness” and texture that Chilean sea bass has and has even higher levels of omega-3s. Like Chilean sea bass, sablefish is forgiving when cooked, making it a good choice for novice cooks. It also allows for the exterior to gain a delightfully crisped coloration while the inside remains perfectly smooth.

Avocado Oil Cooking Benefits

I like to use avocado oil because it is a high smoke-point oil. Medium stove heat is used to pan-sear the fish, which typically ranges between 300-400°F. I like to use avocado oil not only because it’s a healthy and anti-inflammatory fat, but also because it has a high smoke point of 500°F.

Oils that have a lower smoke-point like olive oil (smoke point of 350°F) turn rancid when cooked above a certain temperature, which has been linked to cancer.

Canola oil has a smoke point of 400° and contains omega-3s but has been linked to inflammation if heavily consumed.

How to Make Capers Crispy

Crisping up capers is a bit more work than opening up a jar, but it’s so worth it! Start by draining the capers and dry them well, using paper towels to pat them down. The drier they are, the crispier they’ll become.

Next, heat your oil in the pan, add capers, and cook until crispy, about 2 or 3 minutes. Remove capers from the oil with a slotted spoon or skimmer and let drain on a lined sheet pan or paper towels.

Capers Nutrition

Capers are widely used as a seasoning and garnish in Mediterranean cuisine and are rich in antioxidants, which may reduce inflammation. They also contain small amounts of vitamin K and copper, two essential nutrients.

Other Nutrition Benefits of This Pan Seared Sea Bass

Chives are high in beneficial nutrients, including vitamins (like vitamin K and folate), minerals, and antioxidants.

Lemons are an excellent source of vitamin C and flavonoids, which are antioxidants. Antioxidants help remove free radicals that can damage cells of the body. These nutrients can help prevent diseases and boost health and wellbeing.
