Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
2 pounds Chilean sea bass (or another white fish fillet of your choice, thawed if previously frozen)
Extra virgin olive oil
Kosher salt
Black pepper
1 teaspoon red pepper flakes or 2 teaspoons Aleppo pepper
1–2 lemons, halved
1/4 cup basil pesto (homemade or store bought), plus more to your liking
1 cup grape tomatoes, halved (optional)
Directions
- Position a rack in the middle of your oven and preheat to 425°F. Lightly oil a large baking pan.
- Place the fish in the prepared pan and drizzle with olive oil. Season evenly with salt, pepper, and red pepper flakes or Aleppo pepper. Cover tightly with foil, tenting it so it doesn’t touch the fish.
- Bake for 12 to 15 minutes, or until the thickest part of the fish flakes easily with a fork.
- While the fish bakes, heat a grill pan over medium-high heat. Place the lemon halves cut-side down and sear for about 2 minutes until softened and slightly charred. Set aside.
- Remove the fish from the oven and uncover. Immediately squeeze one charred lemon half over the fish and spread basil pesto on top. If using, toss the halved tomatoes with a pinch of salt and olive oil, then scatter them over the fish. Serve right away with remaining lemon on the side.

Variations
You can easily customize this dish to suit your taste. Swap Chilean sea bass for cod, halibut, or haddock. Replace pesto with a garlic butter sauce or a chimichurri for a different flavor profile. Add vegetables like asparagus or zucchini to the baking pan for a complete one-pan meal. For a milder version, skip the chili flakes and use smoked paprika instead.
Storage/Reheating
Store leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, place the fish in a covered baking dish and warm gently in the oven at 300°F until heated through. Avoid microwaving if possible, as it may dry out the fish.
