Add in the white wine, stir, and allow the mixture to come to a gentle simmer. Stir in the basil, lemon juice, lemon zest, salt, sugar, and pepper and cook for 2 minutes.

Heat oil in a large saute pan over medium heat. Pat the cod dry with paper towels. Then season both sides of cod with salt and pepper.

Pour the white wine tomato basil sauce over the cod, let the sauce warm up for a minute, then remove from heat and and serve at once.
