• Fried Onions
• Green Onions

How to Make Potato Soup 

In our house, we truly think this is the best potato soup recipe. Not only is it delicious, but - as I already mentioned - it uses just four ingredients and is ridiculously simple to make. Plus, all you need from an equipment standpoint is a single pot - yup, that's it! 

So, let's not waste any more time, let's get into the recipe!

Step 1: Prepping The Soup

To start, pull out a big pot and put it over medium-high heat. Then, add a tablespoon of butter and the diced onions to it.

Cook the butter and onions for a few minutes until the onions are golden.

While that's cooking, wash, peel, and chop the potatoes. Then, add them to the pot with some water and cook for about 15 minutes or until the potatoes are soft and fork-tender.

Step 2: Blending The Soup

Now, return the diced and cooked onions to the pot, adding the rest of the butter, salt, and pepper. 

Then, use an immersion blender - or transfer everything to a regular blender - and blend everything until smooth or until it reaches the consistency of preference. If you want chunky potato soup, just pulse the mixture a few times.

Step 3: Finishing Off The Soup

Once the soup is blended, add it evenly to four bowls.

Then, either top it with some sour cream, chopped green onions, grated cheddar cheese, bacon bits, and fried onion strings or make it your own way and use any toppings you like. 

However you eat this 4 ingredients potato soup, it'll be delicious, so enjoy!

How To Store The Soup 

If you're making this potato soup just for yourself, you can look forward to having some leftovers for the next few days. And, honestly, it might even be better the days after you make it.

So, to store those leftovers just put them in an airtight container and keep them in the fridge. Stored this way the soup will stay good for 4 days.

Alternatively, to store it even longer, you can freeze the potato soup. Again, you'll just want to store it in an air-tight container, but instead of keeping it in the fridge, you'll want to keep it in the freezer. It will stay good for around 6 months frozen.

How To Reheat The Soup

To reheat the leftover potato soup, you can either put it in a pot set over medium heat until it's warm, or you can reheat it in the microwave for a few minutes. Either way will work just fine. I usually just use the microwave to reheat it since it's faster.

FAQs About This Potato Soup Recipe

What types of potatoes are best for potato soup?  

Russet potatoes are typically the best ones to use for potato soup since they'll give the soup a super creamy consistency.

With that said though, all types of potatoes work to make this soup, you just might notice a change in consistency depending on which ones you use. Russet potatoes give the soup a more starchy and hearty texture. Reds are more grainy and textured when blended. And, finally, yukon golds are unbelievably buttery soft, and decadent when processed. Experiment and see what potatoes you like best!

How do you thicken up potato soup?

The key to thickening potato soup is cooking the potatoes until they are tender and then blending them together along with the rest of the ingredients. When the potatoes are blended, they combine with the butter to make a thick and creamy soup consistency that is just delicious.

So, you'll want to make sure you blend up everything enough, or the soup will not thicken. I like to use an immersion blender to do this.

How do I spice up bland potato soup? 

I think this soup is pretty tasty on its own, especially if you add the toppings to it.

But, if you think your potato soup tastes bland, you can spice it up by adding in some extra seasonings and spices. Some excellent spices to add are cayenne pepper powder, ancho chili powder, paprika, or just keep it classic and add in some garlic and onion powder.

For what it's worth, sometimes I like to add a little ranch flavor to the soup by adding a couple of tablespoons of some Hidden Valley Ranch seasoning. It's so, so good. I highly recommend giving it a shot.

My Final Thoughts

Well, that is how to make potato soup with only 4 ingredients! 

This savory, hearty, and flavorful soup is about as easy as making soup from scratch gets and the entire family is sure to love it.
