Sausage and Kale Soup - In Bowl with Spoon on Wood Board

Soup is the most underrated category of food in my opinion, and easily one of my favorite things to make and eat. And my favorite part about this Sausage Potato Kale Soup is it has an incredibly short ingredients list, but still manages to have tons of flavor. Those are the best recipes!

Like most soups, one of the best parts about this recipe is that the leftovers keep beautifully. On days when I don’t feel like cooking lunch or dinner, it’s nice to be able to heat a bowl of this up in the microwave and eat something nutritious.

Ingredients You’ll Need:

There are only 6 ingredients involved here, and they are:

  • olive oil
  • yellow onion
  • andouille sausage
  • yukon gold potatoes
  • kale
  • chicken broth

Oh, and salt, but that doesn’t usually count as an ingredient. Despite this short list, the soup manages to be hearty and delicious, with lots of flavor from the smoked andouille sausage.

Since there are so few ingredients in this soup, it’s essential to use a good quality, flavorful andouille sausage. I buy smoked andouille sausage, which adds a smokiness, spiciness, and meatiness to the soup. The one my grocery store carries is made by Wellshire Farms and I really like it!

Tips for Best Results

Use good chicken broth – I once did a taste test comparing several brands of chicken broth, and the differences were staggering. My favorite brands are Imagine and Swanson, but you may want to do your own taste test with the options available at your local grocery store. I also recommend determining if you prefer broth or stock more. Although many people think of them as interchangeable, they are different. Broths are typically made more with meat whereas stocks are made more with bones, giving a different type of mouthfeel. Either will work here, it’s just personal preference.

Remove the stems and ribs from the kale – While optional, I recommend stripping the kale leaves from the stems. You can do this by either cutting the stems out with a knife, or running your fingers up and down the length of the stem to separate the leaves. The leaves are much more tender.

Step by Step Overview:

To get started, brown some sliced andouille sausage in a big soup pot with olive oil, or your fat of choice. Butter and lard are also delicious.

Remove the sausage with a slotted spoon, leaving the fat behind, and cook chopped yellow onion with a pinch of salt, until softened:

Next add big chunks of Yukon gold potatoes:

Can you use other varieties?

My favorite potato to use here is Yukon gold, but you may use any type of waxy potato that you prefer. Red potatoes are another great choice. Russet potatoes, which are typically used for things like French Fries or Hash Browns are not the best choice, as they are too starchy.

Now add chicken broth or stock to the pot:

Simmer for 15 minutes, until the potatoes are fork tender.

Finally, add one bunch worth of kale leaves, and the reserved sausage, and cook for 2 minutes until the kale is wilted:

It is always surprising to me that those 2 minutes are all that’s needed for the kale to lose any traces of bitterness. I love the flavors of the soup!

How to Serve

The soup is now ready to serve in bowls, piping hot, and enjoyed. Soups very classically pair with breads like Drop Biscuits and Asiago Black Pepper Bread, but it’s simply great as is if you wish to keep it lower carb. You can also make it low carb by leaving out the potatoes, but I love the heartiness they bring.

This soup is Whole30 friendly, as is this Carrot Coconut Soup, which also makes for great leftovers. Other favorites are Slow Cooker White Chicken Chili, Cheesy Lasagna Soup, and Quick Chicken Noodle Soup. Enjoy!

Recipe Tips and FAQ

How do you store leftover Sausage Potato Kale Soup?

Keep in an airtight container in the fridge for up to 5 days.

Can you freeze Sausage and Kale Soup?

Yes, store in an airtight container for up to 3 months. Because the liquid will expand as it freezes, make sure you leave some extra space in the container. To thaw, leave in the fridge overnight for best results.

How do you reheat Sausage Kale Potato Soup?

The microwave is the most convenient option. Heat servings in a microwave-safe bowl in 30 second intervals until warmed through. You may also reheat on the stovetop over medium high heat until warm. If reheating straight from frozen, I recommend reheating on the stovetop.

Notes

Because there are so few ingredients in this soup, it’s important to use a really good andouille sausage. I like Wellshire Farms smoked andouille sausage, which adds smokiness, spiciness, and meatiness to the soup.
