Pinto beans simmered with melting cheese, chiles, and onion for a creamy, savory side. This vegetarian, protein-packed family comfort food is a northern Mexican favorite.
Heat a large skillet over medium heat and melt the butter until foamy.
Add the diced onion and sauté for 4–5 minutes, stirring, until soft and translucent.
Stir in the chopped green chiles and cook for 2 minutes, allowing their aroma to bloom.
Add the cooked pinto beans with their liquid, salt, pepper, and cumin. Stir well and cook for 8–10 minutes at a gentle simmer, mashing some beans for a creamier texture if desired.
Reduce heat to low. Stir in the whole milk, then gradually add the shredded Monterey Jack cheese, mixing constantly until the cheese is melted and the mixture is creamy and smooth. Serve hot.
