Ingredients for Rosemary Garlic Mashed Potatoes
To make about 6 servings, you’ll need:
-
2 pounds (900 g) Yukon Gold or Russet potatoes
-
1 whole bulb of garlic (roasted)
-
2–3 sprigs of fresh rosemary (finely chopped)
-
½ cup (120 ml) heavy cream or whole milk (warmed)
-
½ cup (1 stick) unsalted butter (melted)
-
Salt and freshly ground black pepper (to taste)
-
Olive oil (for roasting garlic)
Step-by-Step Instructions
1. Roast the Garlic
Cut the top off a bulb of garlic, drizzle with olive oil, wrap in foil, and roast at 375°F (190°C) for 35–40 minutes until soft and caramelized. This mellows the sharpness and enhances its sweetness.
2. Boil the Potatoes
Peel (optional) and cut potatoes into even chunks. Place in a large pot of salted cold water, bring to a boil, and simmer until fork-tender (15–20 minutes).
3. Infuse the Cream with Rosemary
Warm the cream (or milk) with chopped rosemary in a saucepan over low heat. Let it steep for 5–10 minutes, then strain to remove any large bits. This step ensures the potatoes soak up all that rosemary flavor.
4. Mash the Potatoes
Drain the potatoes well, return them to the hot pot, and let excess steam escape for a minute. Mash with a potato masher or ricer until smooth.
5. Combine Everything
Squeeze out the roasted garlic cloves into the potatoes. Add melted butter, rosemary-infused cream, salt, and pepper. Stir until silky and fluffy.
6. Garnish and Serve
Top with an extra drizzle of melted butter, a sprinkle of rosemary, or freshly cracked black pepper. Serve immediately while hot.

Choose the Right Potato:
