Ingredients

Scale
  • 2 lbs Yukon Gold potatoes, peeled and cut into 1-inch chunks
  • 1 cup water
  • 1 tsp kosher or sea salt, plus more for seasoning
  • 4 tbsp unsalted butter, cut into cubes
  • 1/2 cup whole milk, warmed
  • 1/4 cup sour cream
  • 2 cloves garlic, minced (optional)
  • 1/2 tsp freshly ground black pepper
  • 2 tbsp chopped chives or parsley (optional, for garnish)

Instructions

  1. Peel the Yukon Gold potatoes and cut into even 1-inch chunks.
  2. Place potatoes in the Instant Pot. Add water and sprinkle with salt.
  3. Secure the lid, set valve to Sealing, and select Manual/Pressure Cook for 8 minutes. It will take about 5 minutes to reach pressure.
  4. While potatoes cook, warm the milk and prep the butter.
  5. When timer beeps, carefully quick release the pressure. Open the lid.
  6. Drain any excess water if needed.
  7. Add butter, warmed milk, sour cream, and minced garlic to the potatoes.
  8. Mash with a potato masher for chunky potatoes or use a hand mixer on low for a smooth texture. Do not overmix.
  9. Stir in black pepper and additional salt to taste.
  10. Garnish with chopped chives or parsley and serve immediately while hot.

Notes

For dairy-free, use vegan butter and unsweetened oat or almond milk. For extra flavor, add roasted garlic or a splash of chicken broth. Do not overmix to avoid gluey texture. Keep warm in the Instant Pot if serving later and add extra milk if needed. Leftovers can be refrigerated for up to 4 days or frozen.
