Refried beans originated in Mexico where theyâre called frijoles refritos, or âwell-fried beans.â Basic refried beans are made from four simple ingredients: pinto beans, onion, garlic and bacon fat or lard. Cooks brown chopped onion and minced garlic in the fat and then add canned pinto beans to the skillet together with fluid from the can. As the beans heat up, theyâre mashed with a fork or potato masher to create the desired consistency.
