Preheat the oven to 400°F. Add cream cheese, sour cream, Thousand Island dressing, and Swiss cheese to a medium bowl. Using an electric hand mixer, mix everything together until well combined.
Add corned beef and sauerkraut, mixing again until everything is mixed together.
Grease a 9x9-inch baking dish (or a pie plate) and pour the cream cheese mixture into the prepared dish, using a spatula to spread it out evenly.
Bake for 10-15 minutes, or until everything is melted. If you'd like the top to be golden brown, turn the broiler on for 2-3 minutes.
