Equipment
- Large pot
- Colander
- Foil
- Baking sheet
- Potato masher or ricer
- Mixing bowl
- Measuring cups & spoons
Ingredients
- 2 lbs Yukon Gold or Russet potatoes, peeled and cubed
- 1 bulb garlic, cloves separated and peeled
- 1 tbsp olive oil (for roasting garlic)
- 2 tbsp fresh rosemary, finely chopped
- ½ cup heavy cream
- ¼ cup whole milk
- 4 tbsp unsalted butter
- 1 tsp kosher salt (plus more for boiling water)
- ½ tsp black pepper
- Optional: ¼ cup cream cheese or Parmesan for extra richness
- Optional: olive oil and oat milk for dairy-free version
Instructions
- Roast Garlic: Preheat oven to 375°F (190°C). Wrap garlic cloves in foil with olive oil. Roast for 30–40 minutes until golden and soft.
- Boil Potatoes: Place cubed potatoes in a large pot of salted water. Boil until fork-tender, about 15–20 minutes.
- Drain & Steam: Drain potatoes and return to pot. Let sit uncovered for 2–3 minutes to steam off excess moisture.
- Mash: Add butter, warm cream, milk, roasted garlic, and rosemary. Mash until smooth and creamy.
- Season: Stir in salt and pepper. Taste and adjust seasoning.
- Serve: Garnish with extra rosemary, cracked pepper, or a drizzle of olive oil.
Notes
- For ultra-smooth texture, use a potato ricer.
- Mash while potatoes are hot for best absorption of butter and cream.
- Roast garlic ahead of time and refrigerate for up to 1 week.
- Make ahead: Store in fridge for 2 days or freeze in portions for up to 1 month.
- Reheat gently with added cream or butter to restore texture.
