Heat oven to 400 degrees. Measure fish fillets at the thickest part. Drizzle fish with olive oil, sprinkle with salt and pepper, and place on a rimmed baking sheet, skin side down if you've left the skin on.
STEP 2
Roast fish for 10 minutes per inch of thickness, until the fish is opaque and tender when pierced with a fork but before it starts to flake. Serve with lemon wedges, drizzled with more good olive oil.
