# Expert Tips:

01 -
  • That crispy cornflake topping is your secret weapon for impressing everyone at the table.
  • Nothing beats the creamy, cheesy bite with just a hint of onion and garlic—it's the side that always disappears first.
02 -
  • Skipping the thawing step will leave you with unevenly baked, watery potatoes—a mistake I made and never repeated.
  • Hand-shredding cheese melts smoother and tastes bolder than anything pre-shredded.
03 -
  • Let your casserole cool just enough so the structure holds—hot cheese needs a minute to set.
  • Mix some scallions in for a fresh bite right before baking.
