Reuben soup combines corned beef, potatoes, sauerkraut and Swiss cheese in a simple creamy dish. It’s the perfect way to use up St. Patrick’s Day leftovers!

If you asked me what my favorite deli sandwich is I’d probably have to think long and hard between a hot pastrami on rye (class NYC right there) or a Reuben.

The one thing a Reuben sandwich has over hot pastrami to probably give it (the ever so tiny) win is one ingredient in my opinion: sauerkraut.

Gosh I love that stuff.

In fact, I love all fermented vegetables but sauerkraut in particular is a solid favorite.

With melted Swiss cheese, it’s what gives a Reuben the upper hand in the long list of deli sandwiches.

Something about that sour fermented tang with the salty corned beef is just the perfect flavor combination. It’s why I love it paired with air fryer brats too.

I’ve made Reuben steaks before (and damn, they’re good if I do say so myself) and when I was trying to brainstorm some ideas for how to use leftover corned beef you might have after St. Patrick’s Day, Reuben soup is what came to mind.

Creamy and comforting Reuben soup is a great recipe for using up leftover corned beef this St. Patrick's Day.

Sure, you can make a corned beef breakfast hash or corned beef tacos, those are both delicious recipes using corned beef.

But, if your March is anything like ours right now in New York, it’s cold as heck out there.

A creamy corned beef soup studded with potatoes, sauerkraut and melted Swiss cheese sounds a tad bit more comforting and fitting.

How Do I Make Reuben Soup?

The main ingredients in this Reuben soup recipe are very similar to the sandwich:

  • corned beef
  • sauerkraut
  • Swiss cheese
  • potatoes

Potatoes are the one difference but really add a nice heartiness to this creamy soup.

Unlike super heavy creamy soups, this recipe uses just ¼ cup cream at the end. The broth is mainly chicken broth so it’s not as much of a dietary splurge as it may look.

Fennel seeds, Worcestershire sauce and a bay leaf give the soup its flavor along with garlic and onions sautéed in some butter to start (like any good soup).

You can use any sauerkraut you like but I’ve recently been buying the Cleveland Kraut brand and absolutely love their spicy gnar gnar kraut.

I used it in this Reuben soup and it added such a fun spicy kick that as a total spice freak I couldn’t get enough of.

The method to make this Reuben soup is like any other simple stove top soup:

  1. Sauté onions and garlic in some butter
  2. Add flour to help thicken.
  3. Add spices, potatoes, corned beef and sauerkraut.
  4. Simmer in the chicken broth until potatoes are tender.
  5. Add heavy cream, cheese and scallions, stir and serve.

This Reuben soup is a hearty, creamy and comforting easy recipe that tastes just like the classic sandwich.

What If I Don’t Have Leftover Corned Beef?

No worries, I’ve got a hack for you!

And this totally applies if you want to make this soup at any other time throughout the year not around St. Patrick’s Day since it can be hard to find corned beef outside of the month of March.

Ask for corned beef at the deli counter and have them slice it very thick (ideally in one big chunk).

All you have to do is chop it up at home before throwing it into the soup pot.

If you love a Reuben sandwich you'll love this creamy soup made with corned beef, sauerkraut and Swiss cheese.

Can I Make Reuben Soup in the Slow Cooker or Pressure Cooker?


I didn’t test this recipe either way because it’s honestly too easy and quick on the stove top for those methods to make sense.

One of my pet peeves with pressure cooker recipes is when people use it to make things that don’t need to be made in a pressure cooker (aka: cheesecakes and pasta – picture me rolling my eyes here).

This Reuben soup recipe is not something that needs to be made in the pressure cooker.

Leave the Instant Pot for cabbage soup or other worthwhile recipes.

If you’re using leftover corned beef or corned beef from the deli counter, the meat is already cooked and doesn’t require pressure to cook fast or become tender.

Not to mention, this whole recipe is probably ready start to finish in the same time it would take the pressure cooker to just come to pressure in the first place.

This Reuben soup with potatoes takes all the classic flavors of the sandwich and turns it into a creamy, delicious soup.

If you wanted to make this in the slow cooker because you want dinner ready when you get home from work, I can totally understand that and would do the following:

  • Sauté onions and garlic in butter on the stove top.
  • Add flour until thickened.
  • Add mixture to the slow cooker along with the remaining ingredients except heavy cream, Swiss cheese and scallions.
  • Cook on low for 6-8 hours
  • Add cream, Swiss cheese and scallions 10 minutes before serving.
Give this creamy, hearty Reuben soup recipe a try this St. Patrick's Day, it's the perfect way to enjoy corned beef this holiday.

For someone who has never really been into St. Patrick’s Day, I’m sorta digging its food this year.

From healthy shamrock shakes to brown bread muffins, Bailey’s ice cream, no-bake Irish Cream cheesecakes and two fun breakfast options of either green oatmeal or green spinach pancakes, I can’t say I’m too upset about weird leprechauns, made up pots of gold and 4-leaf clovers.

I still refuse to get on the green food dye bandwagon though.

The Irish can keep that one.

  1. 5 stars
    Super easy and unbelievably delicious! Husband and daughter dislike sauerkraut but LOVED this! I will be cooking corned beef more often just so I can make this with the leftovers. Thank you so much for the deliciousness!

  2. Being Irish I can assure you that people in Ireland DO NOT eat green food unless it’s scallions , leeks, and such. Our Irish stew is basically potatoes, carrots, and lamb stew meat. Corned beef and cabbage is an American dish originating in that area of New York City where Irish immigrants lived on one side of the street and Jewish immigrants on the other side. I know this because a good friend who grew up in that area told me about this.
