What cheese is best for queso fundido?
Oaxaca is the classic for that stretchy pull. If you cannot find it, low-moisture mozzarella works. I like pairing it with Monterey Jack for a smoother melt. Avoid pre-shredded if you can since the anti-caking agents can make the melt less silky.
Is queso fundido the same as queso dip?
Not quite. Queso fundido is typically a thicker, melted-cheese dish (often served in a skillet) that you scoop with tortillas. Tex-Mex queso dip is usually looser and may use processed cheese, a roux, sodium citrate, or evaporated milk to stay pourable.
How do I keep queso fundido from getting oily or grainy?
Keep the heat gentle once the cheese goes in, and use a good melting cheese (Oaxaca, Jack, Asadero, Chihuahua). If it starts to look oily, pull it off the heat first. A tablespoon of milk can help smooth it out, but it is not magic, so stir gently and stop once it looks glossy again. Also, do not over-broil. You want bubbles and browned spots, not an oil slick.
Can I make it without chorizo?
Absolutely. Swap in sautéed mushrooms, black beans, rajas (strips of roasted peppers and onions), or just go full cheese-and-chiles. If you want that savory punch, add a pinch of smoked paprika and a little extra salt.
Can I make queso fundido ahead of time?
You can prep the components ahead: cook the chorizo mixture and roast the poblano. When it is party time, reheat the chorizo base in the skillet, add cheese, and melt right before serving. Queso fundido is happiest fresh and hot.
