If you’ve been adding milk or water to your mashed potatoes for years, it’s time to rethink your method. According to many well-known chefs, including culinary stars like Gordon Ramsay and Thomas Keller, the real secret to velvety, flavor-packed mashed potatoes is not milk or water—but butter and cream. This one simple change can elevate your mashed potatoes from ordinary to restaurant-quality.
Let’s dive into this expert tip and show you how to make mashed potatoes the right way—from a chef’s perspective.
Why Not Milk or Water?
Adding water or plain milk may seem like a harmless shortcut, but it actually waters down the flavor of your potatoes. Water adds zero richness. And while milk has some fat, it still doesn’t compare to the luxurious, silky finish you get from heavy cream and real butter.
Chefs argue that mashed potatoes should taste indulgent—creamy, rich, and full of depth. Water just doesn’t deliver that. Instead, they recommend using warm cream and melted butter to blend the potatoes into a cloud-like, flavorful side dish that feels like pure comfort.
The Chef’s Method for Perfect Mashed Potatoes
