Instructions

  1. Step 1: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
  2. Step 2: Place 4 white fish fillets (5 oz each) on the baking sheet. Drizzle with 3 tbsp extra virgin olive oil and season evenly with 1 tsp salt, 1/2 tsp black pepper, and 1/2 tsp garlic powder.
  3. Step 3: Arrange 1 thinly sliced lemon and 1 cup halved cherry tomatoes around and on top of the fish. Scatter 1/2 cup pitted Kalamata olives and sprinkle 1 tbsp chopped fresh oregano leaves over everything.
  4. Step 4: Roast in the oven for 12-15 minutes until the fish flakes easily with a fork and the tomatoes are tender.
  5. Step 5: Remove from oven and serve immediately, spooning pan juices over the fish for extra flavor.
