  3. Using 2 metal spatulas, transfer cod to serving dish. Stir basil and vinegar into sauce and season with salt and pepper to taste. Spoon sauce over cod and drizzle with extra oil. Serve.

Why This Recipe Works

For our slow-cooker version of this dish we prepared the classic bell pepper base and added garlic, thyme, paprika, and wine for a deeper flavor. Thinly slicing the peppers and onions proved to be well worth the effort, as they cooked down to a soft, velvety consistency; bigger slices still maintained some crunch and marred the smooth texture of the sauce. Once the sauce was prepared, we simply nestled the cod into the liquid and let the fish braise in the moist environment. We rounded out the peperonata with balsamic vinegar for a rich and slightly sweet finish.
