These simple pinto beans with onions are so delicious and addictive! They are really hearty and full of flavor, and really fill you up! This easy recipe is my favorite way of cooking pinto beans from scratch!
Soak the pinto beans in a bowl of water overnight, then drain.
Put drained pinto beans in a pot full of water. Bring to boil, reduce heat to low and simmer, covered, for 1 hour. Drain the pinto beans.
While the beans are cooking, heat the oil in a non-stick frying pan over medium-high heat. Add the onions and cook, stirring occasionally, for 5 minutes.
Add the beans and ketchup to the onions and stir to combine. Cover and cook on Low for 5 minutes.
