Mediterranean Sea Bass
Sea bass fillets soak up a slow-simmered sauce of onion, fennel, tomatoes, white wine, and briny Kalamata olives, while fresh basil lifts every bite with bright fragrance. Each forkful delivers tender fish against the sauce’s deep, savory warmth.

Ingredients
- 1 tbsp extra virgin olive oil
- 1 cup chopped yellow onion
- 3 clove garlic (minced)
- 1/4 tsp crushed red pepper flakes (or to taste)
- 1/2 cup chopped fennel
- One 28 ounce can whole peeled tomatoes (with their juices)
- 3/4 cup fresh basil leaves (very thinly sliced)
- 1/2 cup dry white wine
- 1/4 cup pitted Kalamata olives (halved)
- Kosher salt
- Freshly ground pepper
- Four 4-6 ounce skinless Chilean sea bass fillets
- Organic olive oil cooking spray
- Kosher salt
- Freshly ground black pepper
- 1 tbsp extra-virgin olive oil
Instructions
- Set the racks in the middle and upper thirds of the oven and preheat the oven to 425 F
- In a large skillet over medium heat, heat the olive oil until shimmering. Add the onion, garlic and red pepper flakes and cook until golden, stirring occasionally, about 5 minutes.
- Add the fennel and cook until the vegetables are soft and translucent, an additional 3 to 5 minutes.
- Reduce the heat to medium and add the tomatoes with their juices. Using the back of a wooden spoon, smash the tomatoes and cook for 5 minutes.
- Add the basil, wine, olives, 1 teaspoon salt, and 1/8 teaspoon black pepper.
- Reduce to low and simmer for 15 minutes, or until the sauce is slightly thickened, while you prepare the fish.
- Pat the fillets dry, lightly spray them with cooking spray, and season with salt and pepper.
- In a heavy ovenproof skillet over high heat, heat the olive oil until shimmering. Add the fillets, rounded-side down, and cook for 2 minutes.
- Carefully flip the fillets with a metal spatula and place the skillet in the oven. Bake until the fish is no longer translucent, 8 to 10 minutes.
- Switch the oven to broil and place the skillet on the upper rack. Broil until the tops of the fillets are golden brown, 2 to 4 minutes.
- Arrange the fillets on individual plates, spoon on the sauce, and serve.
