If you really want to impress, combine Russets and Yukon Golds. This dynamic duo covers all bases—fluffiness from the Russet, structure from the Gold. It’s like peanut butter and jelly, but with more cheese and less choking hazard.
And please, use a mandoline slicer for even cuts. Nothing ruins a potato bake faster than chunky slices that take forever to cook while thin ones burn. I speak from experience: I once served a bake where half the potatoes were raw and the other half were charcoal. My dog loved it; my guests did not.
Final advice: don’t overthink it. Grab a bag of Russets or Yukon Golds, slice them thin, layer them with cream, garlic, and cheese, and bake until the top is golden and bubbling. That crunch on top? Absolute magic. The whole house will smell like a fancy restaurant, and you’ll feel like a hero. Now go forth and potato.
