Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Slice the top 1/4 inch off a whole garlic bulb, drizzle with 1 tbsp olive oil, wrap in foil, and roast for 40 minutes until cloves are soft and golden.
  2. Step 2: Meanwhile, place 2 lbs peeled and 1-inch cubed russet potatoes in a large pot, cover with cold water, add 1 tsp salt, and bring to a boil. Simmer potatoes for 15-18 minutes until fork-tender.
  3. Step 3: Drain potatoes thoroughly and return to the pot. Squeeze roasted garlic cloves out of the bulb and mash them into the potatoes with 4 tbsp unsalted butter.
  4. Step 4: Warm 1/2 cup whole milk and 1/2 cup heavy cream in a small saucepan over low heat until hot but not boiling, then gradually stir into the potatoes until smooth and creamy.
  5. Step 5: Season mashed potatoes with 1/2 tsp black pepper and additional salt if needed, then mash again until fluffy and well combined.
