To prepare the Sous vide, you will first need to fill its container with water, then adjust the temperature to 132°F (55.6°C). Leave it to preheat.
Season your cod filets by rubbing ½ tablespoon of olive oil on both fish sides with the seasoning mixture made of garlic powder, paprika, salt, and pepper.
Place the fish fillets in a zip-lock bag with the lemon slices. Make sure they are spread in one layer to properly and equally cook.
Now, for the ‘Water displacement’ technique, close the bag containing the codfish completely except one corner to allow air to come out. Dip the bag in a water filler container, keeping the zip-line above the water surface. Close the zip-line completely.
Dip the bag completely into the sous vide container. You can use sous vide weight magnets or kitchen metal tongs to make sure the bag doesn’t float on the surface
Cook for 30 minutes.
Remove the codfish pieces from the bag using a fish spatula to avoid them from falling apart when the time is done.
Sprinkle the chopped parsley and serve immediately. You can serve the fish on tortillas for tacos, potatoes, or pasta.
