The Reuben is a perfect sandwich. Savory, tender corned beef, melty Swiss cheese, tangy sauerkraut, and zesty Russian dressing are all stacked on caraway seed-studded rye bread. Turning such a masterpiece into a casserole is a no-brainer—it takes everything you love about a Reuben and turns it into a crowd-pleasing, easy-to-assemble dish with layers of cubed pumpernickel-rye bread, chopped corned beef (or pastrami!), and shredded cheese, all with a generous dressing drizzle.
Just like with the sandwich, you can tailor this casserole to suit your tastes. Swap in half of the corned beef for pastrami, or use Thousand Island dressing instead of Russian. Can’t decide between pumpernickel or rye bread? Try a pumpernickel-rye swirl, or use half pumpernickel and half rye. Whatever you do, make sure you make the Russian dressing from scratch. Justin’s recipe features an extra kick from horseradish that’s a great complement to the rich, cured beef. It's well worth the extra few minutes, and it'll really take this dish over the top, we promise!
