Traditional Queso Fundido

Why This Traditional Queso Fundido Works

During the first few minutes in the skillet, the chorizo browns and some of its fat melts out into the pan. That melted fat coats the onions and poblano peppers, so they soften instead of drying out. As the onions cook, they turn clear and a little sweeter, and the peppers lose their raw bite but still keep some texture. By the time the pan is done, the chorizo, onions, and poblanos feel like one mixture instead of separate pieces.

In the oven, the shredded Oaxaca and Monterey Jack start to melt and flow around the chorizo mixture. Because the cheese is shredded, it melts evenly and doesn’t sit in big clumps. The fat from the chorizo mixes into the melted cheese, so the cheese stays smooth and stretchy instead of turning oily on top and rubbery underneath. Once it comes out of the oven, the lime juice and cilantro hit the hot cheese and chorizo, so their sharp, fresh taste spreads through the rich, melted cheese instead of getting cooked away.

Mistakes To Avoid

Letting the chorizo stay pale and undercooked leaves a lot of fat trapped in the meat. Once it goes into the oven, that fat melts out into the cheese, so the dish turns greasy and the meat pieces taste soft and pasty instead of browned and slightly crisp.

Cooking the chorizo and onions on very high heat can burn the bits stuck to the pan. Those scorched pieces end up mixed into the cheese and keep cooking in the oven, giving the whole dish bitter, hard specks and a slightly burnt smell.

Adding the cilantro and lime juice before baking seems easier but causes problems. The cilantro turns dark and limp in the oven, and the lime juice can make the top layer of cheese tighten and turn a little rubbery instead of stretchy.

Letting the queso sit too long after baking means the cheese starts to firm up and the fat separates on top. The dip goes from smooth and stretchy to a thick, oily layer over dense cheese that is hard to scoop with chips.
