Mix smoked salmon, chopped onion, and grated cheese together in prepared pie plate. Drop cream cream cubes on top of salmon mixture and set aside.
Beat eggs in a medium mixing bowl. Add milk, Bisquick, and seasonings and mix thoroughly. (I do this step in a my blender.)
Pour egg mixture into pie plate over smoked salmon mixture.
Bake 35-40 minutes, or until a knife inserted halfway between the center and the edge comes out clean. Allow to stand at least 10 minutes before serving.
