Why You'll Love This Poached Sea Bass

This healthy recipe is incredibly easy and quick to make. It's a wonderful way to enjoy sea bass and full of tangy flavor.

The way the fish is poached, it ends up so tender and flaky and takes on the flavors from the sauce.

I think the Castelvetrano olives really make this dish - they add an amazingly flavorful and salty punch that livens up the meal.

Ingredients You'll Need

Sea Bass - You'll need 2 sea bass fillets. Try to find 6-ounce fillets. I've found that to be a perfect amount per person. You can use skinless or skin-on fillets. Just remove the skin before serving.

Roma Tomatoes - You'll need 2 ripe Roma tomatoes for this dish. You'll slice them into ¼ inch rounds.

Onion - You'll use ½ a yellow onion, that you'll thinly slice.

Castelvetrano Olives - You'll need ¼ cup of Castelvetrano olives for this recipe. You'll halve them and add them once the fish is done poaching. Castelvetrano olives are a Sicilian olive with a beautiful green color and rich, sweet texture.

White Wine - You'll need 1 cup of white wine for this recipe. Any wine will work (don't use something expensive). I've used both a Sauvignon Blanc and a Chardonnay in this recipe and both were great.

Spices - You'll use 1 teaspoon of dried oregano, 1 teaspoon of red pepper flakes, 1 teaspoon of kosher salt, and ½ teaspoon ground black pepper.

Butter - You'll need 1 tablespoon of butter to sauté the onions in. You can use olive oil as well, but I love the rich flavor of the butter (it pairs especially well with the wine).

Parsley - You'll need ¼ cup of chopped fresh parsley to top the fish after cooking.

How to Find Sustainable Seafood

For those of you that might be wondering about the sustainability of sea bass, I highly suggest checking out these recommendations from the Monterey Bay Aquarium's Seafood Watch site.

It's great to check in advance of going to the store to see what seafood you can buy that makes less of an impact on the ocean and climate.

With the recommendations of this site and your local fishmonger, you'll be able to find great fish that's environmentally sustainable.
