Chilean sea bass, also known as Patagonian toothfish, is a delicate, flaky fish that when cooked properly can be a showstopper. Keith Castro, Thirsty Lion Gastropub & Grill’s vice president of food and beverage, offers a Mediterranean-inspired Chilean sea bass recipe this week that’s easy to make at home, with one caveat: Don’t overcook the fish.

The secret to this recipe is making sure the pan and oil are hot enough before adding the fish, Castro says. Also, make sure you season the fish with salt only before cooking. “If you season with pepper or garlic, it’s going to burn in the pan.”

The fish should be done in 6-8 minutes, Castro says. “If you sear it in high-quality olive oil, you’ll get a really nice crust on the fish. It’s super tender and will just melt in your mouth if you cook it correctly.”

At the restaurant, Castro serves the dish with red lentils and Israeli couscous.
