Sure, everyone knows that corned beef makes a great sandwich but did you ever think of turning it into soup?
This soup version of a Reuben is one of my family’s favorite ways to enjoy the leftovers in a warming soup.
It’s full of the delicious flavors you expect from the sandwich in a hearty, cozy soup that’s filling enough to satisfy even my hungry, growing brood of boys.
- Unsalted butter – Don’t use salted unless it’s all you have. It may make it a bit too salty for some.
- Aromatics – Yellow onions, garlic, and chives give this soup great flavor and make it smell delicious. Try to go for fresh garlic and chives but in a pinch you could use dried.
- Corn beef slices – This is great way to use up St. Patrick’s Day leftovers.
- Flour – The flour will help thicken the broth.
- Chicken broth – This forms the majority of the soup’s body. Beef broth is too strong, and I don’t recommend it.
- Sauerkraut – I use a fresh can, but you can use left overs from a corned beef dinner if you want.
- Sour cream – You can use regular or a reduced fat if you prefer.
- Swiss Cheese – I like to use a block and shred it myself, but you could use a bag of shredded cheese instead.
How to make
Once it is melted, add the onions and cook until soft and translucent.
This should take about 5 minutes.
Make sure you stir them frequently as they cook to help avoid burning them.
When the onions are ready, add the garlic and cook for about 1 minute or until it becomes fragrant.
Make sure you keep stirring to help prevent burns.
Next, stir in the flour and cook for another minute before pouring in the chicken broth.
Next, stir in the corned beef and sauerkraut.
Bring the soup to a boil and then reduce to a simmer.
Cover the soup and then allow it to simmer for 15 minutes.
After 15 minutes, uncover and add in the sour cream, chives, and 1/2 of the shredded Swiss cheese and give it a good stir.
Allow the soup to cook for another 2 to 3 minutes to give the cheese a chance to melt.
Finally, ladle the soup into bowls and garnish with the remaining Swiss cheese.
Serve hot with rye bread on the side.
Serving and storing – including homemade croutons!
You can serve the soup fresh and hot with a side of rye bread.
The rye bread is a great tool to soak up some of the soup or scrape out your bowl.
If you want to get fancy, you can cut your rye bread into cubes and toast it in the oven at 400 degrees for about 5 minutes.
You can then sprinkle them on top of the soup as a homemade crouton.
Pumpernickel bread or even pumpernickel rye both also make great options for this.
I love adding extra cheese to the top.
Sometimes my family will also add an additional spoonful of sour cream to the top.
To store, you can ladle the cool soup into an airtight container and then place in the fridge.
It should keep for about 3 to 4 days.
You can reheat it in the microwave or add it back to a pot and heat over medium-low heat until warmed through.
Tips and tricks
- Make sure you drain the sauerkraut well if you are opening up a new can.
- Serve with rye bread or your favorite rolls.
- Cut the corned beef into bite sized pieces that can fit easily on a spoon.
- Use low sodium chicken broth if you want to reduce the amount of salt you are eating.
