What are the Key Ingredients for Reuben Casserole

Bread – Reubens are all about the distinctive look and flavor of rye bread! However, any bread will work. Or make a no-bread version using cooked pasta shells or mashed or boiled and sliced potatoes on the bottom in Step 1.

Corned Beef – Buy canned corned beef or get some from the deli. A butcher can cut thick slices into cubes for you.

Sauce – Thousand Island dressing and lots of melty Swiss cheese give this casserole its tangy flavor and creamy consistency. Make your own quick Thousand Island by whisking together a ¼ cup of mayonnaise, 1 tablespoon each of ketchup and sweet pickle relish, ⅛ teaspoon of onion powder, & a dash of Worcestershire.
