Preheat your oven to 400°F (205°C). Line a baking tray with parchment paper.
Pat the Chilean Seabass fillets dry with paper towels. Season both sides with salt, pepper, and garlic powder.
In a non-stick skillet, heat 2 tablespoons of olive oil over medium-high heat. Once hot, sear the seabass fillets for about 3 minutes on each side, until golden brown.
Transfer the seared seabass to the prepared baking tray. Drizzle with lemon juice and bake in the preheated oven for 7-10 minutes, or until the fish flakes easily with a fork.
While the fish is baking, prepare the fennel and orange salad. In a large bowl, combine the sliced fennel, orange segments, and sliced almonds.
In a small bowl, whisk together 2 tablespoons of olive oil, white wine vinegar, salt, and pepper. Pour this dressing over the fennel and orange salad and toss to coat evenly.
Sprinkle the chopped dill over the salad and give it a final toss.
Once the seabass is cooked, remove it from the oven and let it rest for a few minutes.
Serve the Chilean Seabass hot, accompanied by the fennel and orange salad on the side.
