For all of those who don’t like fish because of the fishy smell, this keto white fish recipe is a must-try for you. When you prepare white fish with sauce, it doesn’t have that fishy smell like the other types of recipes.

Some popular choices of fish you can use include cod, haddock, halibut, tilapia, sole, bass, snapper, pollock, grouper, and flounder due to their mild flavor and versatile cooking options.

This low carb white fish recipe bursts with flavors because the fish itself is covered with delicious and fragrant buttery and lemony sauce.

As you probably already know, fish is packed with protein. They also provide a good source of vitamin B, selenium, iodine, and omega-3 fatty acids. Fish is also a vital part of the growth and formation of strong bones.

Research shows that fish is a good source of polyunsaturated fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which have been shown to decrease the risk of cardiovascular disease, support neurological health and formation, aid in visual development in infants, and reduce the risk of inflammatory conditions and cancers (1). 

The American Heart Association recommends eating 1 gram of EPA/DHA each day to help prevent coronary heart disease (2). For healthy people, the AHA recommends consuming fish at least twice per week, which should equal around 500 mg of EPA/DHA. 

EPA and DHA have further been shown to positively impact blood pressure, endothelial function, blood vessel flexibility, inflammation, blood sugar, and platelet aggregation activity to prevent blood clots (3).
