Instructions

Cut the two pounds of russet potatoes into thin rounds with slightly irregular edges and small differences in thickness. The pale slices should overlap loosely instead of forming neat stacks. The potatoes now have a flexible layered shape that will allow the creamy sauce to reach between the slices during cooking.
Combine the melted butter with flour until the mixture becomes a thick pale paste. Stir in the milk with the onion and garlic until the sauce changes from thin and milky to smooth and lightly thickened. Fold in one and one half cups of cheddar with the salt and pepper until uneven ribbons of cheese disappear into a glossy golden sauce.
Spread one third of the potato slices loosely across the slow cooker then pour over part of the cheddar sauce so several edges remain visible. Repeat the uneven layers until all potatoes and sauce are used. Shift several slices toward the sides and tuck others into the center so the arrangement looks casual with overlapping rounds and visible pockets of sauce.
Cook the layered potatoes until the slices soften and settle into the sauce. The sauce should become thicker while small bubbles appear around the edges and the upper potato slices turn creamy yellow. Gently shift a few softened slices near the center so sauce rises between them while the layered structure remains visible and naturally uneven.
Scatter the remaining half cup of cheddar unevenly over the tender potatoes then cover until the cheese melts into irregular golden patches. Dust with smoked paprika and let the dish rest until the sauce settles around the soft layers. Scoop one portion onto a white plate so several potato layers fold naturally and reveal the creamy interior. Finish with chopped chives and leave the melted cheese edges uneven and lightly browned.

Notes

Pro Tips:

Slice the potatoes close to one eighth inch thick because overly thick rounds can remain firm after the sauce has finished cooking.
Use freshly shredded cheddar because packaged cheese often contains coating agents that can make the sauce less smooth.
Avoid lifting the slow cooker lid during the first three hours because released heat can noticeably extend the cooking time.
Let the finished potatoes rest uncovered for fifteen minutes so the sauce thickens and the tender layers hold together better.

Storage: Cool the leftover potatoes until they stop steaming then transfer them into a shallow airtight container. Refrigerate them within two hours so the dairy sauce remains safe and fresh. Store the potatoes in the refrigerator for up to four days. Keep the layers together when possible because smaller broken pieces can dry out more quickly during reheating. Reheat individual portions until hot throughout. Add a small splash of milk before reheating when the sauce looks very thick because the potatoes continue absorbing moisture as they chill. Freezing is possible although the potato texture may become slightly grainy and the sauce can separate. Thaw frozen portions overnight in the refrigerator then reheat gently and stir only around the edges.
