In bowl, combine cheese, mayonnaise, crabmeat, artichokes, horseradish, parsley and pepper sauce. Spoon into shallow 4-cup baking dish (a 9-inch tart pan or 9-inch pie plate work well).
Bake at 350°F for 25 minutes, until bubbly. Garnish with additional parsley, if desired. Serve warm with crackers.
