Authentic Queso Fundido
The Tex-Mex classic that started every great meal. Bubbling melted cheese with chorizo and roasted peppers.
Queso Fundido — literally "melted cheese" — is the crown jewel of Tex-Mex appetizers. Unlike the processed queso dips you find in jars, authentic Queso Fundido uses real melting cheeses (Oaxacan string cheese and Chihuahua) that become silky smooth when heated. The key is roasting the poblano peppers to add a subtle smoky, earthy depth. At Big Red Enchilada, we've been serving this recipe since 1988, and guests order it at almost every table. The chorizo renders its spiced fat into the cheese, creating an irresistible flavor you simply can't stop eating.
Ingredients
- 8 oz (225g) Oaxacan quesillo (string cheese), shredded or pulled into strings
- 8 oz (225g) Chihuahua cheese (or Monterey Jack), grated
- 6 oz (170g) Mexican chorizo, casings removed
- 2 fresh poblano peppers
- 1 small white onion, finely diced
- 3 cloves garlic, minced
- 1 tablespoon olive oil
- 1/2 teaspoon dried Mexican oregano
- Salt and pepper to taste
- Fresh cilantro, for garnish
- Warm corn or flour tortillas, for serving
Instructions
- Roast the poblanos: Place poblano peppers directly over a gas burner flame (or under the broiler) and char all sides until blackened, about 8–10 minutes. Transfer to a zip-lock bag, seal, and let steam for 10 minutes. Peel off charred skin, remove seeds, and dice the flesh into small pieces. The charring gives the peppers their distinctive smoky flavor.
- Cook the chorizo: In a 10-inch cast-iron skillet over medium heat, cook the chorizo, breaking it up with a spoon, until it renders its fat and becomes crispy at the edges, about 6–8 minutes. Remove chorizo with a slotted spoon, leaving the spiced oil in the pan.
- Sauté aromatics: In the same skillet with the chorizo oil, add the diced onion and sauté over medium heat until softened and translucent, about 3–4 minutes. Add the garlic and cook another 60 seconds until fragrant.
- Add roasted peppers: Stir in the diced roasted poblanos and dried oregano. Cook for 2 minutes, stirring to combine all flavors.
- Melt the cheeses: Reduce heat to medium-low. Add the shredded Oaxacan cheese and grated Chihuahua cheese in two batches, stirring gently in a figure-eight pattern with a wooden spoon. The key is low heat — too high and the proteins will seize and become stringy. Once both cheeses are melted and smooth, scatter the cooked chorizo over the top.
- Serve immediately: Bring the skillet directly to the table (use oven mitts!). Garnish with fresh cilantro. Serve with warm tortillas on the side — corn tortillas for authenticity, flour for dipping ease.
Chef's Tip: For the creamiest queso, choose cheeses at room temperature — cold cheese from the fridge will clump. If the queso starts to get stringy, add 1–2 tablespoons of warm evaporated milk and stir vigorously. To keep it warm at the table, place the cast-iron skillet on a trivet or wooden board — it will stay hot for 10+ minutes.
The beauty of this recipe is its simplicity. You're not making a complex sauce — you're letting the quality cheeses speak for themselves, amplified by the smoky pepper and savory chorizo. Queso Fundido is best enjoyed the moment it's made, scooped generously onto a warm tortilla.
