Ingredients
- Russet potatoes: essential for that fluffy yet creamy texture Try to pick ones that feel heavy and have no blemishes
- Salted butter: adds richness and flavor Always use high quality real butter for the best taste
- Milk: helps lighten the texture Choose whole milk if you can for extra creaminess
- Sour cream: gives tang and makes the potatoes extra smooth
- Grated Parmesan cheese: brings a nutty depth Freshly grated cheese melts more smoothly
- Garlic powder: provides all that lovely garlic flavor without overpowering Always check your garlic powder is fresh for boldness
- Salt and black pepper: round out and enhance all the flavors Use Kosher salt for even seasoning
For the Gravy
- Salted butter: starts the gravy with a smooth rich flavor
- All-purpose flour: thickens the gravy Use a plain white flour for best results
- Water and milk: create just the right consistency Make sure your milk is fresh for a clean taste
- Chicken bouillon cubes: pack in savory notes Crush well so they dissolve fully
- Pepper: adds a touch of gentle heat

Hands down my favorite ingredient here is the Parmesan cheese It takes the potatoes from good to dreamy in just a handful I remember my grandmother leaning in the doorway taking that first bite and declaring these better than the restaurants That was the best review I could ever want
