Comfort Food: Reuben Casserole ♥ Recipe

Reuben Casserole ♥, great for leftover corned beef, quick, easy & very tasty.
Today's easy casserole recipe for St. Patrick's Day or afterward to use up leftover corned beef, a reuben sandwich, deconstructed in casserole form using corned beef, sauerkraut and Swiss cheese.

When the butcher asked if I wanted the "big" piece of Kobe corned beef for our St. Patrick's Day feast, I was sure a "small" one would be plenty. "Are you sure?" he encouraged. "It's really good." So I charged ahead, "Sure, a big one, it is." Good advice, good decision. The Kobe beef was spectacular, moist and meaty and fork tender in my long-time favorite Corned Beef & Cabbage. The only downside to lots of meat turns out to pure upside: great leftovers. This casserole, it's a keeper. [Note to Vegetarians]

This recipe is a big favorite on Pinterest! It's so easy to throw together, just a handful of ingredients. It makes for a nice light supper one night and with just the two of us, gets finished off in grilled sandwiches the next. Wonderful!

"[With cream cheese for an appetizer ...] it's exceptional." ~ Diana


Hands-on time: 15 minutes
Time to table: 45 minutes
Serves 4 as main dish, 8 as side dish

Baking spray, for the dish
16 - 32 ounces "good" sauerkraut (see ALANNA's TIPS), rinsed, drained and squeezed
8 ounces cooked corned beef, diced
2 tablespoons grated onion
8 ounces Swiss cheese, grated
1/2 - 1 cup light Thousand Island dressing (see ALANNA's TIPS)
Pepper to taste

Heat oven to 350F/180C. Spray an 8x8 or 9x9 or pie dish with cooking spray. In a large bowl, stir together all the ingredients. Spread the mixture in the baking dish. Bake for about 30 minutes.

LEFTOVERS Leftover Reuben Casserole makes mean grilled-cheese sandwiches. Another reader adds cream cheese and serves it as a spread at parties, great idea!

"GOOD" SAUERKRAUT Huh? This usually means "anything but canned sauerkraut". In fact, the best sauerkraut comes in jars and bags, look for these in a refrigerator case. And there's a cottage industry with sauerkraut, I often come across local brands of sauerkraut: these can be amazing!
GRATED ONION Grate the onion on the large holes of a cheese grater, this lets the tiny bits of onion both distribute better throughout the casserole and ensures that the onion actually cooks. (FYI I've had the same four-sided cheese grater for years but like this looks of how this two-sided cheese grater folds flat for storage. Handy!)
THOUSAND ISLAND I'm a stickler for this adage, Never Buy Salad Dressing Again! so my fridge door doesn't have a "salad dressing shelf" like so many do. Instead, I make my own Homemade 1000 Island dressing. But use what you have, bottled dressing will work just as well. If it were me, I'd thin the dressing with a little milk before using it.
WHO KNEW? A 32-ounce jar of sauerkraut yields only 16 ounces of useable sauerkraut! I suspect when I made this the first time that I bought a 16-ounce bag of sauerkraut and so my casserole contained only 8 ounces of actual sauerkraut. It also explains why that first time, I used only a half-cup of Thousand Island Dressing where since then, with double the sauerkraut, the casserole really needed a full cup.
VARIATIONS I might cook some egg noodles or add some caraway or spinach or top it all with mashed potatoes. It's a casserole: it's flexible! A reader suggests topping the casserole with buttered rye bread crumbs: brilliant!

  1. Wow that looks really good. Cabbage is so good for us we can all use more cabbage in our diet.

    Happy St. Patricks Day!

  2. Whenever I make corned beef (and it's not too often), I hope for leftovers. My favorite way to use them is in hash, but this casserole looks delicious and I will absolutely try it. The couple of days after St. Patrick's Day are a great time to pick up corned beef on sale in the supermarket, for those who don't want to corn their own.

  3. creative. I would have never in a million years thought this one up. I'll have ot give it a try!

  4. Now that is really looking good and I love your attitude that it's a casserole and open to playing around!

  5. Sounds amazing---a new spin and easy enough.

  6. LOVE your column and the wonderful ideas it brings..SARAH

  7. I wanted you to know, by adding some cream cheese to your recipe, it makes a great appetizer for parties. It's exceptional. I'm going to give your casserole a try ... I love corned beef and cabbage.

    Iam thinking this needs some toasted ,buttered rye bread cubes (croutons) on top.

  9. i love how with vegetables, you can make things like casseroles and it doesn't have to be just a dull vegetable.

  10. looks so good. I'm going to have to make this.

  11. I'm trying this tonight- thanks so much for the recipe!
