What you will need

This recipe uses 5 simple ingredients that you can find at any grocery store:

  • 2 lbs russet potatoes, peeled and cubed
  • 4 cups chicken broth
  • 0.75 cup sour cream
  • 1 tsp salt
  • 1 tbsp olive oil

Step by step instructions

Step 1: Cook the Potatoes

Place the peeled and cubed potatoes in a large pot and pour in the chicken broth. Add salt and bring to a boil over high heat. Reduce to a simmer and cook for 15 to 18 minutes until the potatoes are completely fork-tender.

Step 2: Mash or Blend

Remove from heat. Use a potato masher to mash about half the potatoes directly in the pot for a chunky-style soup, or use an immersion blender to puree to your desired consistency.

Step 3: Stir in Sour Cream

Stir the sour cream into the hot soup until fully incorporated and the soup is thick and creamy. Return the pot to low heat and warm gently for 2 minutes. Taste and add additional salt if needed before serving.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • sour cream → plain Greek yogurt for a lighter and higher-protein version
  • chicken broth → vegetable broth to make the soup vegetarian

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Adding the sour cream while the soup is still at a full boil, which causes it to curdle and create an unpleasant texture
  • Cutting the potato cubes too large and unevenly, resulting in some pieces being undercooked while others fall apart
