Ingredients for Our favourite creamy mashed potatoes
1,800 g yukon gold potatoes, peeled, cut into 5 cm pieces
6 large garlic cloves, peeled
20 g kosher salt, divided, plus more
300 ml full-fat milk
4 sprigs thyme
170 g unsalted butter, divided
2 g freshly ground black pepper, plus more
120 g soured cream
1 potato ricer or food mill
How to make Our favourite creamy mashed potatoes
Cover the potatoes, garlic, and 1 tablespoon of salt with cold water in a large pot.
Bring to a low boil, then reduce the heat and simmer until the potatoes are very tender when pierced with the tip of a sharp knife but not falling apart, about 20–25 minutes.
Meanwhile, heat the milk, thyme, and 170 g of butter in a small pot over medium heat, stirring until the butter has melted.
Remove from heat and set aside, discarding the thyme.
Drain the potatoes and garlic, then return them to the pot. Toss over low heat for 1–2 minutes until the moisture evaporates.
Using a potato ricer or food mill, immediately press the potatoes and garlic into a large bowl while still warm.
Gradually stir in the milk mixture, reserving about 120 ml if you plan to make the dish in advance.
Season with 2 teaspoons of salt and 3/4 teaspoon of pepper.
Fold in the sour cream and stir gently with a spoon until fully incorporated and very smooth, being careful not to overmix to avoid gummy potatoes.
Taste and adjust the seasonings as needed.
Serve topped with the remaining 30 g of butter and additional pepper.
The mashed potatoes can be made up to 2 hours in advance; cover and store at room temperature. Alternatively, chill covered for up to 8 hours and reheat over medium heat with the reserved milk mixture.
