What Ingredients are in Potato Soup?

Ready to gather everything you need for soup perfection?

  • 5 pounds potatoes, peeled and diced small
  • 3 quarts water
  • 2 tablespoons salt
  • 1 tablespoon MSG (optional)
  • 3 pounds onions, chopped
  • 1 cup butter or margarine
  • 1/2 cup all-purpose flour
  • 4 quarts milk
  • 2 cups cream
  • White pepper, to taste
  • 1 cup chopped chives or scallion tops for garnish

When shopping for potatoes, starchy varieties like russets work best for creating that velvety, smooth texture we’re after. The MSG listed is technically optional, though it does enhance the savory qualities—feel free to omit if you prefer. And while the recipe calls for cream, you could substitute with all milk or even undiluted evaporated milk if you’re looking to lighten things up a bit. The chives or scallions aren’t just pretty garnish; they add a fresh, bright contrast to the rich, creamy soup that honestly makes all the difference.

How to Make this Potato Soup

creamy potato soup recipe

Making this crowd-pleasing potato soup starts with proper preparation of your potatoes. Peel 5 pounds of potatoes and dice them into small pieces—the smaller the dice, the quicker they’ll cook and the smoother your final puree will be.

Place these potato pieces in a large pot, cover them with 3 quarts of water, and add 2 tablespoons of salt and 1 tablespoon of MSG (though you can skip this if you prefer). Bring the pot to a boil, then reduce to a simmer and cook until the potatoes are completely tender and practically falling apart.

Now comes the fun part: grab a whisk or potato masher and beat those softened spuds until you’ve created a smooth puree. Some folks like to use an immersion blender here, which works wonders for that velvety texture we’re all secretly craving.

While your potatoes are cooking, it’s time to create the aromatic foundation of your soup. Melt 1 cup of butter in a separate heavy-bottomed pan and add your 3 pounds of chopped onions.

Cook these onions with patience, my friends—you want them golden and translucent, not brown and bitter. When the onions reach that perfect golden state, sprinkle in 1/2 cup of all-purpose flour and cook for a few minutes, stirring constantly.

This roux is what gives our soup body without becoming gloppy. Gradually pour in 4 quarts of milk, creating a smooth sauce as you stir. The key word here is “gradually”—add too much milk at once and you’ll end up with lumps that will haunt your soup dreams.

Let this mixture simmer for about 10 minutes, stirring frequently to prevent any scorching on the bottom. For an authentic touch, consider using Mexican cast iron cookware which retains heat beautifully and creates even cooking temperatures. Finally, combine your onion sauce with the potato puree, add 2 cups of cream, and gently heat the mixture through.

Season with additional salt if needed and a touch of white pepper for complexity. When serving, a sprinkle of those vibrant chopped chives or scallion tops isn’t just pretty—it’s the perfect fresh counterpoint to all that creamy richness.

Potato Soup Substitutions and Variations

While the classic potato soup recipe serves a crowd beautifully, you can easily adapt it to suit dietary restrictions or whatever ingredients you happen to have on hand.

For dairy-free versions, swap the butter for olive oil and use coconut milk or your favorite plant milk instead of dairy. Veggie broth makes a flavorful liquid base if you’re skipping the cream entirely.

Got different herbs? Rosemary, thyme, or dill work wonderfully in place of chives.

And let’s talk toppings—bacon bits, shredded cheese, or crispy fried onions can transform a simple soup into something extraordinary. Who doesn’t love customization options?

What to Serve with Potato Soup

Several perfect pairings can elevate your potato soup from a simple starter to the star of a complete meal.

I love serving it with crusty sourdough bread or warm garlic breadsticks for dipping into that creamy goodness. A crisp, green salad with a tangy vinaigrette provides the perfect contrast to the soup’s richness.

For heartier appetites, consider grilled cheese sandwiches cut into fingers, or a charcuterie board with sharp cheddar and smoky ham.

Trust me, the combination of savory soup and these accompaniments will have everyone asking for seconds.

Bonus points for a light fruit dessert afterward!
