How to Make Sour Cream Mashed Potatoes: Step-by-Step

1. Boil the Potatoes

Place cubed potatoes in a large pot of cold, salted water. Bring to a boil over medium-high heat and cook for 15–20 minutes or until fork-tender. Drain well and return to the pot to let steam off any excess moisture for 1–2 minutes.

2. Mash the Potatoes

Mash the potatoes using a potato masher, ricer, or electric mixer. Mash until smooth and lump-free, depending on your texture preference.

3. Add the Flavor

Stir in butter and warmed milk or cream until incorporated. Then fold in the sour cream, salt, and pepper. Mix until creamy and smooth. Taste and adjust seasoning if needed.

4. Serve and Garnish

Transfer to a serving dish. Garnish with fresh chopped chives or parsley if desired. Serve warm.

Tips and Variations

• Don’t Overmix: Overworking potatoes can make them gluey. Use a light hand or a ricer for the best texture.
  
• Warm Ingredients: Always warm the milk and butter before adding to prevent cooling down the potatoes and to ensure smooth blending.
  
• Add Cheese: Stir in grated Parmesan, cream cheese, or cheddar for an extra savory boost.
  
• Garlic Lover’s Version: Add roasted garlic or sautéed minced garlic for extra flavor.
  
• Lighter Option: Use Greek yogurt instead of sour cream for a higher-protein, tangy substitute.
