It should take about 11 minutes to cook cod on the stove using this recipe, but it will depend on the thickness of your fish. The cod is done when you can flake it with a fork. When the pan comes to a boil, you can cook the fish covered for 10 minutes. Then you can turn off the heat and let the cod continue to steam in the covered pan for a few minutes until you're ready to serve it. The cod will be very tender.
