Little Potato Buns
Little Potato Buns are a classic vintage party appetizer that transforms leftover mashed potatoes into warm, cheesy bites served on small rounds of rye bread. Popular throughout the mid-20th century, recipes like this often appeared in community cookbooks and home entertaining collections, making use of simple refrigerator staples such as bacon, cheese, sour cream, and eggs. The potato mixture becomes rich and creamy while baking into a lightly golden topping. Their small size makes them perfect for cocktail parties, potlucks, game days, or holiday gatherings. They're easy to prepare ahead of time and bake just before serving, offering a comforting combination of crispy bread, creamy potatoes, smoky bacon, and melted cheese in every bite.
