Top Tips For Cooking Low Carb Fish

Skip the breading. Just season the fish and sear it hot.
Use real fats. Kerrygold grass-fed butter , ghee, or a splash of olive oil works great.
Fish cooks fast. Keep an eye on it so it doesn't dry out.
Use a healthy salt like Maldon Sea Salt Flakes or Oryx Dessert Salt to add minerals to your meals.
Fish is done when it flakes. Once it's opaque and flakes with a fork, it's ready so be careful not to overcook it.
Add lemon or lime at the end. It brightens up the flavor.
Cauliflower rice, steamed broccoli, or a fresh green salad are all you need for sides.
