Instructions

  1. Step 1: Place 2 lbs diced russet potatoes in a large pot, cover with cold water, and add 1 tsp salt. Bring to a rolling boil over high heat, then reduce to a simmer and cook for 15-18 minutes until the potatoes are fork-tender.
  2. Step 2: Drain the potatoes thoroughly in a colander, shaking off excess water. Return the pot to low heat for 1 minute to evaporate any remaining moisture, then transfer the potatoes back to the pot.
  3. Step 3: Add 4 tbsp unsalted butter and 1 minced garlic clove to the hot potatoes. Mash vigorously with a potato masher until mostly smooth, then gradually stir in 1/4 cup whole milk while continuing to mash until the mixture is creamy and free of lumps.
  4. Step 4: Season with 1 tsp salt and 1/4 tsp black pepper, stirring until fully incorporated. Test for seasoning and adjust if needed, then serve immediately while hot.
