Prepare the Fish: Rinse the California Corbina fillets under cold water and pat them dry with a paper towel.
Season the Fish: Drizzle the fillets with olive oil, sprinkle with salt, pepper, and lemon zest. Let them sit for 10-15 minutes to allow the flavors to meld.
Heat the Pan: Place a non-stick skillet on medium-high heat. Once heated, add olive oil or butter.
Cook the Fish: Place the fillets in the skillet and cook for 4-5 minutes per side, or until golden brown and the fish flakes easily.
Finish and Serve: Remove the fish from the skillet and squeeze fresh lemon juice over the top. Garnish with chopped parsley and serve immediately.
