Stuff the inside of the fish with plenty of lemon slices and place on a sheet pan.
Mix together ½ cup of water for every 2 cups of kosher salt to form a paste. Mound the salt mixture around the fish, making sure to cover the bottom, sides and top (see picture above).
Bake at 425 degrees for 30 – 45 minutes, depending on the size of your fish. (The last time we made this, our fish was almost 3 pounds, so we baked it for 45 minutes.)
Crack open (it’s fun to do at the table!) and serve with your favorite salad and side dishes.
