Roasted Mashed Potatoes With Heavy Cream

Pro tips

• Roast potatoes at 400°F uncovered to allow moisture to evaporate and concentrate flavor—don't cover with foil.
• Warm the heavy cream and butter before folding into potatoes to prevent the mixture from cooling and becoming gluey.
• Mash while potatoes are still hot for the smoothest texture; cold potatoes resist mashing and require excessive effort.
• Season conservatively at first, then taste and adjust salt and white pepper—it's easier to add than remove.

Substitutions

• Heavy cream → half-and-half or whole milk (result will be less rich)
• Unsalted butter → salted butter (reduce added salt by 1/4 teaspoon)
• White pepper → black pepper (flavor is identical; white pepper avoids visible specks)

Storage & make-ahead

Store in an airtight container in the refrigerator for up to 3 days; reheat gently on the stovetop with a splash of cream.

Why roast potatoes instead of boiling for mashed potatoes?

Roasting concentrates the potato flavor by removing excess moisture, resulting in a richer taste and creamier texture than boiled potatoes.

Can I use Yukon Gold potatoes instead of russets?

Yes. Yukon Golds will produce slightly creamier results but may require less butter since they have higher natural fat content.

How do I know when roasted potatoes are done?

Potatoes are ready when a fork easily pierces the flesh and the skin begins to brown slightly, typically 45-60 minutes at 400°F.

Can I make this ahead of time?

Yes. Prepare up to 2 days ahead and refrigerate. Reheat gently on the stovetop with a splash of cream, stirring occasionally.

What's the best way to keep mashed potatoes creamy?

Use warm cream and butter, add them gradually while mixing, and avoid overworking the potatoes, which can make them gluey.
