Grandmother’s Potato Soup Recipe

My Grandmother’s Potato Soup Recipe makes an old-fashioned, easy, comforting soup recipe. Made with 5 ingredients and no heavy cream! Instant Pot instructions included.
Soup always makes one of my favorite meals. Like our favorite vegetable soup and chicken and dumplings, this is one of the soups that I grew up loving the most. Before there was such a thing as loading a potato soup with bacon, cheese, and onions, my Grandmother Verdie made her potato soup very simply – with potatoes, milk, butter, and salt and pepper. If my sister Wendy and I knew that Grandmother made this soup for supper, we’d beg to be able to eat supper with her. With one bite, it is so easy to understand why!
The Best Potato Soup Recipe
You could add all sorts of things to this soup if you’d like, but I recommend starting with this simple, basic recipe and go from there. Most times, we would rather stick with this version than add a lot of other ingredients, like leeks, onions, and whatnot.
Simple really is best most of the time, isn’t it?
How to Make The Best Potato Soup Recipe
To make Grandmother’s easy potato soup recipe, you’ll only need a few ingredients and to follow a few steps.
Ingredients
Be sure to see the recipe card below for the full listing of ingredients, instructions, notes, and estimated nutritional information.
- Potatoes – I prefer to use russets. You’ll need 2 pounds, about six medium. You can also use Yukon gold potatoes.
- Water – You will need enough fresh, clean water to cover the potatoes.
- Milk – I use whole milk in my potato soup. You can also use your favorite dairy-free milk substitute.
- Butter – the butter adds so much flavor to this soup.
- Salt and Pepper – add salt and pepper to taste for seasoning.
Step-by-Step Instructions
- Prep potatoes. begin by scrubbing your potatoes clean, peeling, and then cutting them into about 2-inch chunks. Place the potatoes into a large soup pot (I use my Dutch oven), cover it with clean water, and stir.
- Cook. Cook over medium heat until the potatoes are fork-tender, about 20 minutes. Remove from the heat and drain away the water from the potatoes. Add your whole milk and butter to the potatoes and place back on medium heat. Allow the milk to bubble slightly around the edges of the soup pot, about 5 to 10 minutes.
- Season. Remove from the heat and season with salt and pepper to taste.
Creamy Potato Soup Recipe Without Adding Flour
To customize the consistency and texture of this soup recipe, you can serve it as shown with tender chunks of potatoes or you can make a smooth and creamy soup by using an immersion blender in your soup pot until it reaches the consistency you prefer. No need to add flour or make a slurry with this simple trick! Naturally gluten-free! But really, the chunkiness is simply perfect and I definitely recommend that you give it a try!
If you like a smoother textured soup with all the trimmings (think sour cream, cheddar cheese, bacon, and green onions), you may want to check out my creamy Loaded Potato Soup Recipe as well.
Dairy-Free Potato Soup
To make this soup dairy-free, replace the milk and butter called for in the recipe with dairy-free substitutes. A delicious option for dairy-free milk for this soup is coconut milk. I prefer to use the canned version for the added creamy texture. For the butter, there is plant-based butter readily available. Use your favorites!
Can You Make Potato Soup Ahead?
Allow your soup to cool completely and then store it in an airtight container in the refrigerator for up to 3 days. Reheat and serve.
How to Make Potato Soup Recipe in the Instant Pot
This easy soup recipe is so easy to make in the Instant Pot.
- Rather than cooking in the Dutch oven, add the water, potatoes, butter, salt, and pepper to the Instant Pot. Place the lid onto the Instant Pot and turn the vent to seal it. Cook on the manual setting at high pressure for 10 minutes, then use the quick-release feature.
- Remove the lid to the Instant Pot and set the cook setting to saute. Stir in the milk and cook, stirring often, until thickened, about 3 minutes. Turn off the Instant Pot and serve. If you prefer a smooth and loaded potato soup, use an immersion blender to blend the soup and serve it with your favorite toppings.

My Great Grandma Montange, Grandma Sargisson and my mom’s recipe as well. This is the perfect potato soup recipe.
Aren’t these heirloom recipes from our grandmothers the best ever? Thanks, Devin!
I can’t wait to try yr grandma potatoe soup thank you
Hope you enjoy!
I know this is your grandmas recipe so you profitably have fond memories of this recipe but it just didn’t do it for me. It was very very bland, it was ok for tonight as an “I haven’t been able to grocery shop this week” type of meal. But I hopefully won’t be making this again and will stick with my stepdads recipe.
this is exactly how my mom, my sister and myself have always made our potato soup this way!! Always yummy with cornbread!!
Pretty similar to my mom’s potato soup only she added a can of evaporated milk and a little bit of cheese. I like this because I don’t like any other veggies in my potato soup ❤️
Like my mom made ,except she always added frozen peas to the soup.i grew up loving this.
Hi Denise,
I have never had the potato soup with peas added but it sounds good. So glad you enjoyed this. Thanks!
I think this may be just what I have been searching for. My dad made a thin milk soup with potatoes, but he added a pack of frozen peas. I think he also kept some of the potato water. I loved that soup. Can’t wait to try this out. Thank you.
Hi Jean,
Hope you enjoy this soup. I have not made potato soup with peas but it sounds good!
Yes, my Mom and Grandmom too always used evaporated milk too. But I’ll try this.
So nice…It’s also a perfect foundation. Just add a few mussles or crawfish or clams then garnish with parsley or any other herb. Love this one!
Love this. I also like to cut up smoked sausage and add to it. Very yummy.
it’d delicious. I grew up with this soup, although my dad would leave the water and add a can of evaporated milk, salt and PEPPER. ♡
Thanks so much Dawn! One of our favorites!
Oh my gosh, this is the first time I have seen this soup recipe outside of my immediate family. My grandma made this but added chopped onion and diced celery. My dad loved it and grandma taught my mom to make it. Grandma said it was a cheap meal during the depression and it was good for Fridays when they ate meatless meals. Our grandmas knew a good meal didn’t have to be expensive.
It’s a delicious soup isn’t it Debbie?! xo
I have some potatoes ready to sprout. thought I’d make soup. This is going to taste exactly like the potato soup my Mom made…for which I have no recipe. Simple. Beautiful. Delicious. (She added hard boiled eggs…the only difference.)
I’m excited for you to try it Charlene! It’s delicious – hope you enjoy it! Thanks! xo
Can I use 1/2 & 1/2 instead of milk?
Did u try half and half how did it turn out ? As I have that and 2% milk I don’t have whole milk right now. Thank you
Mina, I haven’t tried making this soup with either half and half or 2% milk but someone posted she had made this using whole milk and half and half. You could try it mixing the half and half and 2% milk.
