Sizzling and gooey, queso fundido topped with chorizo is a staple on Mexican restaurant menus across the country. But the dish likely stems from home cooks along North Mexico and South Texas. Depending on where you go, different cheeses like Monterey Jack, Chihuahua or Oaxaca cheeses are used. Bricia Lopez, an author of “Asada: The Art of Mexican-Style Grilling (Abrams, 2023)” and “Oaxaca: Home Cooking From the Heart of Mexico” (Abrams Books, 2019), and an owner at Guelaguetza, in Los Angeles, was inspired by the salsa de queso and quesillo she grew up eating at her family’s restaurant to create her version of queso fundido, which uses the Oaxaca cheese to create a great cheese pull. She also tops it with mushrooms and epazote (see Tip), a fresh herb she grew up eating with cheese.
