Ingredients
- 2 large leeks white and light green parts only, thoroughly rinsed and thinly sliced
- 3 cloves garlic minced
- 5 tablespoons unsalted butter divided (plus more for garnish, optional)
- ¼ cup dry white wine
- 3 pounds Yukon Gold potatoes scrubbed and cut into six pieces each (peeled if preferred)
- ¾ cup chicken broth or vegetable broth
- ½ cup buttermilk
- ½ cup heavy cream
- 2 teaspoons kosher salt heaping, plus more to taste
- ½ teaspoon freshly cracked black pepper
- 1 handful finely chopped chives or scallions for garnish optional
Instructions
- Set the Instant Pot to the sauté function. Once hot, add 1 tablespoon of butter, leeks, and garlic. Sauté for about 3 minutes until translucent.
- Deglaze the pot with white wine, bringing it to a simmer.
- Add the potatoes and broth, stirring to combine. Cover and set the Instant Pot to pressure cook on high for 9 minutes.
- Once cooking is complete, let the pressure release naturally for a few minutes, then use the quick-release function.
- Remove the lid and add the remaining 4 tablespoons of butter. Begin mashing the potatoes directly in the pot.
- Slowly drizzle in the buttermilk and heavy cream while mashing. Stir in salt and black pepper. Mash until smooth.
- Adjust seasoning to taste. Garnish with extra butter and fresh herbs if using. Serve warm.
Notes
- For extra richness, use an immersion blender for ultra-smooth mashed potatoes.
- If you prefer a lighter version, substitute half-and-half for heavy cream.
- These mashed potatoes pair well with roasted meats, grilled chicken, or a hearty vegetarian main.
