I made this using leftovers one night and it came out great! It can be tweaked all different ways to make it your own.

Substituting heavy cream for milk alters the viscosity completely, shifting the base from a broth-leaning emulsion to a heavy, velvety velouté. Starch management dictates the success of potato soups. Boiling diced potatoes directly in water creates a starch-rich cooking liquid that, when combined with a flour-and-butter roux, acts as the primary thickening agent. Incorporating dairy too early can cause curdling if the heat exceeds 180 degrees Fahrenheit. Maintaining a gentle simmer during the milk-incorporation phase prevents milk proteins from scorching at the bottom of a heavy-bottomed saucepan.
Simultaneous multi-vessel cooking requires strict timing discipline. While potatoes soften in one pan over medium heat, translucent onions demand attention in another. Whisking all-purpose flour into melted butter and cooking it for exactly 60 seconds eliminates raw flour tastes before the liquid enters the pan. Gradually tempering cold milk into the hot roux prevents lumps from forming. Grating sharp cheddar cheese on a box grater rather than buying pre-shredded varieties ensures smooth melting, as bagged cheeses contain cellulose anti-caking agents that create a grainy texture in suspension.
Variations in potato cultivars change the starch profile significantly. Russet potatoes contain high amounts of amylose and amylopectin, cells that rupture easily and release thickening starches into the broth. Waxy alternatives like red or fingerling potatoes retain their cellular walls, producing a thinner, more broth-like result that resists thickening even with added flour. Dicing potatoes uniformly to half-inch cubes guarantees even heat penetration during the 15-minute boiling window.
