Mix dip ingredients as directed; refrigerate up to 24 hours. When ready to serve, bake, uncovered, in 350°F oven 20 min. or until hot and bubbly.
For a browner top, place dip under heated broiler immediately after baking. Broil 1 to 2 min. or until lightly browned.
Serve with carrot sticks and/or broccoli florets in addition to the crackers.
