Step 1

Preheat oven to 400 degrees.

Step 2

Layer corned beef on the bottom of a 9x13 baking dish.

Step 3

Make sure the sauerkraut is drained and patted dry. Sprinkle it on top of the beef.

Step 4

Drizzle the dressing on top of the sauerkraut and sprinkle the Swiss cheese on top.

Step 5

Arrange the diced bread on top of the casserole and lightly spray it with cooking spray so that it toasts up nicely (or you can butter the bread).

Step 6

Bake for 20-25 minutes or until bread is toasted and cheese has melted.
