This Southwest Au Gratin Potatoes recipe is cheesy, hearty, and downright delicious! Tender potatoes are baked until golden brown and bubbly in a delicious, cheesy and tangy sauce,
Heat a medium-sized pot over medium heat. Add the butter to the heated pan, and let it melt. Once the butter has melted, sprinkle in the flour, and combine with a whisk. The mixture should form a paste.
Pour the cheesy sauce over the potatoes, or ladle into the individual ramekins if you are using them. Move the potato slices around so that the sauce seeps into the crevices of the potatoes.
