Creamy, buttery, and full of rich Parmesan flavor these mashed potatoes are the perfect side dish for any meal. The secret is a velvety Parmesan cream sauce that makes every bite extra indulgent and perfectly smooth.

Ingredients

3 lbs Yukon Gold potatoes (or Russet), washed, peeled, and cut into 1–2 inch cubes
Kosher salt, to taste
8 Tbsp unsalted butter
2 Tbsp all-purpose flour
¾ cup heavy cream
¾ cup whole milk
1 cup finely grated Parmigiano Reggiano (use a microplane)
White pepper, to taste
Fresh chives or thyme, for garnish

Instructions

Prep the potatoes
Place the cubed potatoes in a large pot and cover with cold water. Rinse the potatoes 2–3 times until the water runs clear to remove excess starch.
Cook the potatoes
Refill the pot with fresh cold water and add a generous amount of kosher salt. Bring to a boil over medium-high heat, then reduce to a simmer. Cook for 15–20 minutes, or until the potatoes are fork-tender.
Make the Parmesan cream sauce
In a medium saucepan over medium heat, melt the butter. Whisk in the flour and cook for 1 minute to remove the raw flour taste.
Slowly pour in the heavy cream and milk, whisking constantly until smooth. Bring to a gentle simmer. Add the Parmesan cheese and whisk until fully melted and creamy. Remove from heat.
Mash the potatoes
Drain the cooked potatoes and rinse briefly under hot water for 1 minute. Pass the warm potatoes through a potato ricer or food mill into the pot. If you don’t have either, use a potato masher for a rustic texture.
Combine and season
Gently fold the Parmesan cream sauce into the mashed potatoes until fully incorporated. Season generously with salt and white pepper. Adjust the texture by adding a bit of warm milk if you prefer softer mashed potatoes.
Serve
Transfer to a serving bowl and top with freshly chopped chives or thyme. Serve warm.

Tips

Rinse thoroughly: Rinsing potatoes removes starch, helping them stay fluffy instead of gluey.
Use warm ingredients: Warm milk and cream blend more smoothly into hot potatoes.
Don’t overmix: Overworking mashed potatoes can make them dense or gummy.
Use quality Parmesan: Freshly grated Parmigiano Reggiano gives the best flavor and texture.

Variations and Substitutions

Cheese swap: Try Asiago, Romano, or aged Cheddar for a twist.
Herb flavor: Mix in roasted garlic, parsley, rosemary, or sage for extra aroma.
Dairy-free option: Substitute butter with olive oil and use non-dairy milk and vegan Parmesan.
Extra creamy: Add a dollop of sour cream or cream cheese for richness.

You can, but use it gently to avoid overmixing and creating a gummy texture.
