A chalupa is a traditional Mexican dish originating from south-central Mexico, particularly the states of Hidalgo, Puebla, Guerrero, and Oaxaca. It consists of a thin layer of masa (corn dough) pressed around a mold to form a small, concave, boat-shaped shell, which is then deep-fried until crisp. This fried masa shell is typically filled with ingredients such as shredded chicken or pork, cheese, lettuce, salsa (red or green), chopped onions, and sometimes refried beans or chorizo. The shape and toppings can vary regionally, with some versions resembling tostadas due to their flat, round shape

. The word "chalupa" means "small boat" in Spanish, reflecting the shape of the masa shell. The dish is considered an antojito (snack) and is served hot, often as lunch or dinner. Traditional chalupas are simpler, topped mainly with salsa, cheese, and lettuce, while Americanized versions, such as those popularized by fast-food chains like Taco Bell, often have thicker fried shells and multiple toppings, resembling a hybrid between a taco and frybread

. In addition, "chalupa" also refers to a type of small boat used in Mexico, especially in the canals of Xochimilco near Mexico City, but this is unrelated to the food item

. In summary, a chalupa is a crispy, fried masa shell shaped like a small boat, filled with savory toppings typical of Mexican cuisine. It is both a traditional Mexican specialty and a popular dish adapted in various forms in the United States
