  • Place sauerkraut in the bottom of the prepared dish. Top with tomato slices and drizzle with salad dressing. Add diced corned beef over top, and sprinkle with grated cheese.

Cooking Just for Two? Cut the ingredients in half and prepare casserole in a 1-quart baking dish. Cooking instructions remain the same.
Want to Prep Ahead? Layer all of the ingredients in the dish and keep covered in the refrigerator for up to 24 hours (until ready to bake). You may need to add 5-10 minutes to the baking time in order to get the dish heated through if you're cooking it cold.
