Grandmother's Potato Soup Recipe (1)

Soup always makes one of my favorite meals. Like our favorite vegetable soupand 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!

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

  1. 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.
  2. 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.
  3. 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.

  1. 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.
  2. 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.

FAQs

What is the best thickener for potato soup? ›

Combine cornstarch and a little bit of water—or the chicken stock from the soup—in a small bowl. With the soup simmering over medium-low heat, whisk in the slurry. The soup should start to thicken almost immediately.

How can I make bland potato soup taste better? ›

Adding an acid like vinegar or lemon juice and incorporating fresh herbs can also help add flavor to a potato soup. While you may not need to implement all of these strategies, it's good to keep them in the back of your mind for when you realize your next pot of soup needs a flavor boost.

Why isn't my potato soup creamy? ›

Why isn't my potato soup creamy? Most creamy soups require you to add dairy of some sort into it. If you're finding your soup is too thin adding milk, add in cream instead, or whole milk.

Does cream cheese thicken up potato soup? ›

Cream cheese can be a delicious and tangy thickener for mashed potatoes so it stands to reason that it can also be used to add body to your favorite silky potato soup recipes — right? The answer is yes. It only works well if you do it carefully, though.

What is the secret ingredient to thicken soup? ›

Add flour or cornflour

Put a tablespoon of either into a small bowl and stir in 2-3 tbsp of the soup until you have a smooth mixture. Stir this back into the soup and bring it to a simmer. Cook for a few minutes to allow the starch granules to burst to thicken, and to cook out any flour flavour.

Is it better to thicken soup with flour or cornstarch? ›

It's important to note that cornstarch has twice the thickening power of flour. If you need to substitute cornstarch to thicken liquid in a recipe that calls for ¼ cup (four tablespoons) flour, you only need two tablespoons cornstarch.

How do you add Flavour to potato soup? ›

The chicken stock adds flavor, and the cream makes the broth creamy and more luxurious. You can also try half-and-half, sour cream, or plain yogurt. Cheese: This is optional, but if you have some on hand, it adds a lovely richness to the soup. Use sharp cheddar for cheesy potato soup that rivals cheesy baked potatoes.

How can I deepen my soup flavor? ›

"If your broth is lacking in savory richness, try adding roasted onion, tomato paste, mushrooms, seaweed, soy sauce, or miso. These ingredients add umami flavor and depth to broth," she says. The choice of ingredient depends on the recipe, though.

How do you keep potatoes from getting mushy in potato soup? ›

Cut the potatoes into rissolettes and blanche them (i.e. cook them briefly, not to full doneness). Use the water you used in the soup and put the potatoes back in when you go to warm the soup again for serving. Since they're cut fairly small, they should be just about done without being mushy when you go to eat.

How do you keep potato soup from getting gummy? ›

It's important not to chop them too finely before cooking. Keeping them in medium-ish sized chunks should work best. If the potatoes are chopped too finely, then too much starch will be released into the broth, resulting in a gummy-like texture.

Can you use instant potatoes to thicken potato soup? ›

Honestly, if you just stir in a little instant mash, like Smash, your soup will thicken up in no time at all. Now, you may end up needing more than a spoonful, but it's best to add a little at a time, because remember, you can always add more of it, but you can't take it away.

What is the best thickening agent for potato soup? ›

Cornstarch is a very effective thickener, and a little bit can go a long way. Add cornstarch to a small amount of cold water or other liquid (wine or stock) and whisk into a thick slurry.

Why won't my cream cheese melt in my potato soup? ›

Cheese is a particularly tricky addition to soups because if the temperature of the soup is too hot or too cold, the cheese won't melt properly and will start to clump. Temperatures over 150 degrees Fahrenheit will cause the cheese to release liquid too fast as a result of broken protein bonds.

Why did Panera stop selling potato soup? ›

Although the dish was scrapped due to declining popularity, its biggest fans have not stopped talking about it online. One disappointed fan wrote one on Twitter this week: “I was today years old when I found out Panera discontinued their potato soup.

How do you make potato soup less gluey? ›

The recommended method here is to press the potatoes through a ricer (instead of using a blender), which gives the soup a light and clean texture and eliminates the gluey consistency common in other recipes.

How to thicken crockpot potato soup? ›

Cornstarch, potato starch, and chickpea flour are a couple of pantry-friendly ways to thicken soups, stews, and sauces in the slow cooker. Just a tablespoon or two of any — added towards the end of cooking — will thicken sauces especially well.

What is the thickener in most puréed soups? ›

Roux (pronounced roo) is a mixture of equal weights (parts) of flour and fat (usually clarified butter; chicken fat, bacon fat, and margarine are also used) cooked over medium heat and stirred constantly. Roux is the most common thickener for sauces and soups.

Does heavy cream thicken soup? ›

Heavy cream

Use heavy cream as a keto-friendly thickening option for your soups and broths. Heavy cream has more fat than regular whole milk, so you can add it to your soup recipes without worrying about it curdling.
