Instructions

• Lay the fillets in a shallow, oven-proof casserole dish or skillet, just large enough to hold the fish in a single layer. Cover the fish with a 1/8-inch thick layer of olive oil (a good brand, but not your best), season with a flaky sea salt and any other herb or spice you like, then send it into a 275-degree oven, basting it often, until it’s cooked through. For a 1-inch thick fish fillet, it takes about 30 minutes
