Whisk broth and flour in a small bowl; stir into the mixture in the skillet.
Cook over medium-low heat, stirring often, until the mixture thickens, about 15 minutes.
Meanwhile, place cauliflower and water in a large saucepan; bring to a boil over high heat.

Sprinkle with the remaining 1/2 teaspoon pepper.
Bake until the top is beginning to brown and the filling is bubbly, 22 to 25 minutes.
Sprinkle with the remaining 2 tablespoons parsley before serving.
