Delicious Thick Creamy Potato Soup

Some of my fondest childhood memories revolve around the aroma of potato soup simmering on the stove. My grandmother, a woman whose kitchen was the heart of our family, had a special recipe. It wasn’t written down, of course; it lived in her hands, her intuition, and the love she poured into every bowl. While I’ve adapted it over the years, adding a touch of heat and a bit more Parmesan, the feeling it evokes remains the same: warmth, comfort, and a sense of home.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 25 minutes
• Total Time: 45 minutes
• Servings: 4-6
• Yield: 6 cups
• Dietary Type: Vegetarian (can be made Gluten-Free)

Ingredients

• 4 large potatoes, peeled and diced
• 2 medium celery ribs, diced
• 1 medium onion, diced
• 1 tablespoon fresh minced garlic (optional)
• 1 1⁄2 cups low sodium chicken broth
• 4 chicken bouillon cubes (I use OXO brand, can use the small packages in place of cubes)
• 1⁄3 cup grated Parmesan cheese
• 1 cup full-fat milk (or use 2 cups half-and-half cream)
• 1 1⁄2 cups sour cream
• 1 tablespoon flour
• Salt & freshly ground black pepper (I use seasoned salt)
• 1 pinch cayenne pepper
• Grated Parmesan cheese, for garnish
• Green onion, for garnish

Equipment Needed

• Large pot or Dutch oven
• Electric mixer or food processor
• Medium bowl
• Whisk
• Ladle

Instructions

1. In a large pot or Dutch oven, combine the diced potatoes, diced celery, diced onion, and minced garlic (if using).
2. Pour in the low sodium chicken broth.
3. Bring the mixture to a boil over medium-high heat.
4. Once boiling, reduce the heat to low, cover the pot, and simmer until the vegetables are tender, about 20 minutes. To check for doneness, pierce a potato with a fork; it should easily slide through.
5. Remove the pot from the heat and let the soup cool slightly. This is crucial for safety when pureeing! Alternatively, you can refrigerate the soup at this point to puree later.
6. Using an electric mixer or a food processor, carefully blend the soup until smooth. It’s perfectly fine (and even desirable, in my opinion) to leave a few chunks of potatoes for added texture. If using a food processor, work in batches to avoid overfilling.
7. Return the pureed soup to the pot.
8. Add the 1 cup of milk (or half-and-half cream), Parmesan cheese, and chicken bouillon cubes (or bouillon packets).
9. Place the pot back on the stove and heat slowly over low heat, stirring occasionally, until the bouillon cubes are dissolved and the soup is heated through. Be careful not to boil the soup at this stage.
10. While the soup is heating, prepare the sour cream mixture. In a medium bowl, whisk together the sour cream and flour until thoroughly blended and smooth. This prevents the sour cream from curdling when added to the hot soup.
11. Gradually temper the sour cream by pouring about 1/3 of the heated potato/milk mixture into the sour cream bowl. Whisk constantly and vigorously to combine. This gradual introduction of heat will prevent the sour cream from separating.
12. Pour the tempered sour cream mixture back into the remainder of the soup in the pot. Stir to combine well, ensuring everything is evenly distributed.
13. Continue to heat the soup gently on top of the stove, stirring frequently, until it is heated through and slightly thickened. Do not boil!
14. Season the soup to taste with salt, freshly ground black pepper, and a pinch of cayenne pepper (if using). I personally prefer using seasoned salt for an extra layer of flavor.
15. Ladle the hot soup into bowls.
16. Garnish each bowl with a generous sprinkle of grated Parmesan cheese and chopped green onions.

Expert Tips & Tricks

• For a richer flavor: Use half-and-half cream instead of milk.
• To make it gluten-free: Ensure your bouillon cubes are gluten-free.
• For a smoother texture: Use an immersion blender directly in the pot. However, be extremely careful to avoid splattering hot soup.
• To add more texture: Before serving, stir in some cooked, cubed potatoes or crumbled bacon.
• To prevent curdling: Tempering the sour cream is crucial! Don’t skip that step.
• Spice it up: Add more cayenne pepper or a dash of hot sauce for extra heat.
• Make Ahead: Prepare the soup up to the point of adding the sour cream. Cool completely, refrigerate, then reheat gently and add the sour cream mixture before serving.

Serving & Storage Suggestions

Serve the potato soup hot, garnished with grated Parmesan cheese and chopped green onions. It’s also delicious with a side of crusty bread or a grilled cheese sandwich for dipping.

Leftover potato soup can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stovetop over low heat, stirring occasionally, or in the microwave. You may need to add a splash of milk or broth to thin it out as it tends to thicken upon cooling.

Freezing is not highly recommended, as the sour cream can sometimes separate upon thawing, altering the texture. However, if you must freeze it, do so in individual portions in freezer-safe containers. Thaw in the refrigerator overnight and reheat gently.
