Wash the pinto beans and soak overnight. You can also boil with water and let it soak afterward for two hours.
Thoroughly rinse and drain the beans, and then add them to the crockpot. In a pan, cook the garlic, onion, and celery in olive oil at medium-high heat for 7 minutes. Add the cooked vegetable to the beans.
Pour in the other ingredients, close the lid and cook for 4 hours at high temperature, 7 hours at low.
Once ready, take out the bay leaves and serve as you wish.
