What is queso blanco?
“Queso blanco” can mean a couple different things. Traditionally, it can refer to a fresh, crumbly white cheese. But in Tex-Mex restaurants and a lot of U.S. home kitchens, queso blanco usually means a white cheese dip: melted white cheese blended with milk and seasonings, often with green chiles and sometimes jalapeño. This recipe is the Tex-Mex dip version, smooth and scoopable.
Why use white American cheese?
Because it melts like a dream. White American cheese from the deli counter (processed cheese) contains emulsifiers that help the sauce stay glossy and stable instead of turning grainy or breaking. You can absolutely add flavor cheeses too, but American is the texture insurance policy.
Can I use Monterey Jack or white cheddar instead?
You can, but you will need a stabilizer and careful heat. Monterey Jack melts fairly well, cheddar is more likely to get grainy. If you want a blend, keep at least half of the cheese as white American for the smoothest result.
How do I fix queso blanco that turned grainy or separated?
Happens to the best of us, and it is usually just too much heat. First, turn the heat to low. Whisk in 1 to 2 tablespoons warm milk and keep stirring. If it is still broken, whisk in 1 teaspoon cornstarch mixed with 1 tablespoon cold milk, then gently heat and whisk until it often smooths back out. If it is being stubborn, whisk in a little more white American cheese to bring it back together. Avoid boiling, that is the usual culprit.
How do I keep queso warm for a party?
Set it in a small slow cooker on Warm. It will hold well for about 1 to 2 hours. Stir occasionally and add a splash of milk if it tightens up. If you are holding it longer, plan on a couple milk splashes along the way to keep it scoopable.
Any easy variations?
Make it spicier: leave the jalapeño seeds in, or stir in a teaspoon of pickled jalapeño brine at the end for tangy heat. Make it heartier: add cooked crumbled chorizo. Smoky version: fold in chopped roasted poblano. If you add juicy ingredients like tomatoes, add a little at a time since they can thin the dip.
