Method
- Put the potatoes in a 6-quart pot and add the water to cover them by 1 inch.
- Stir in 2 teaspoons salt.
- Bring to a boil over high heat, then reduce the heat and simmer uncovered for 15 to 20 minutes, until the potatoes are fork-tender.
- Drain the potatoes and return them to the pot over low heat for 1 to 2 minutes, shaking the pot occasionally until excess moisture steams off.
- Warm the milk in a microwave-safe measuring cup in the microwave for 45 to 60 seconds, until steaming but not boiling.
- Add the butter and cream cheese to the hot potatoes and mash until mostly smooth.
- Gradually mash in the warm milk.
- Fold in the cheddar, Parmesan, remaining 1/2 teaspoon salt, and pepper until the cheeses are melted and the potatoes are creamy.
Notes
For the creamiest texture, steam-dry the drained potatoes before mashing. Refrigerate leftovers for up to 4 days; freezing is suitable for up to 1 month, though the texture may soften after thawing. For a lighter option, use reduced-fat cream cheese and milk.
