Soak 3 cups of pinto beans in a large bowl for 30 minutes.
Chop 1 large onion in 2/3 and peel 2 cloves of garlic.
Rinse the beans and add them to the instant pot. Add water to about half way.
Add the onion, 2 cloves of garlic, and salt to taste into your instant pot. I used about 4 tbsp.
Set your instant pot to Beans/chili and change the time to 1 hour and 25 minutes. Let the pot steam out before fully opening after it beeps.
After the whistle blows, check to ensure they are fully cooked. they should be tender. Serve in a bowl, top with queso fresco and Mexican sour cream, and enjoy!
