# Expert advice:

01 -
  • The roasted garlic melts into the potatoes like silk, giving you deep savory flavor without any harsh bite—it's the kind of side dish that people actually ask you to make again.
  • Parmesan cheese adds a subtle umami richness that makes these potatoes feel fancy enough for company dinners but simple enough for weeknight comfort.
  • They're naturally gluten-free and come together in less than an hour, making them perfect when you need something reliable and delicious.
02 -
  • The biggest mistake I see is adding cold milk to hot potatoes—it cools everything down and makes them gluey and dense. Warm your milk in a small pot or microwave first, and you'll taste the difference immediately.
  • I learned the hard way that over-mashing is the enemy of creamy mashed potatoes. Use a masher or ricer, not a food processor—a food processor breaks down the starch and turns everything into glue. A few small lumps are actually a sign you've done it right.
  • Salting the cooking water is non-negotiable. It seasons the potatoes throughout instead of just on the surface, and it makes the final dish taste complete without needing excessive salt at the end.
03 -
  • Warmed milk and a gently hand-mashed method are the two secrets that separate creamy, luxurious mashed potatoes from the gluey, dense versions that nobody wants to eat.
  • Freshly grated Parmesan cheese melts into the potatoes like silk, while pre-grated versions stay slightly grainy because of the anti-caking agents. It's worth the extra minute to grate it fresh.
