In the beginning, preheat the microwave oven. The temperature for this preheating is 200 degrees which is exactly suitable for your dish.
Take a bowl, which is a mixing bowl of suitable size, and then sift the flour into this bowl. In the flour bowl, add some salt and also mix the black pepper into it.
Then bring the fillets, clean them and dry them with paper towels. Make sure that you have dried them properly.
Then to coat the fillets, you must use salt for sprinkling on one side. Then take a non-stick pan and add butter to this pan. Once the butter is melted and heated enough, start adding the fillets into it.
Cook the fillets at the lowered heat, and sear them in the heated oil. After cooking for some time, flip it.
Cook from both sides until it changes color and is well browned. In between the cooking of these fillets, you must pour some lemon juice into them.
The addition of lemon zest should also be done at this point. Now take the fish fillets out of the heated oil and put them in the heat-safe plates or dish.
Repeat the process with all the fillets and then you must serve these fillets while hot.
Before serving the fillets, bring the freshly chopped parsley over it and also sprinkle some more salt along with the pepper for the final flavor.
Serve as it is on the platter.
