Chorizo Queso Fundido Ingredients

  • Bulk Mexican chorizo sausage – Introduces a smoky, spicy depth, transforming the dish with its unmistakable character. Remove casings and coarsely chop if needed.
  • Caramelized onions – Adds a subtle sweetness to the overall flavor.
  • Roasted poblano pepper – Adds a slightly sweet and smoky flavor, without adding to much additional heat. Poblano peppers have the same heat rating as green bell peppers, in fact jalapeño peppers have more heat than poblanos.
  • Roma tomato – Diced tomato adds a pop of color and fresh flavor.
  • Variety of cheeses – Including Oaxaca and mozzarella, creates a gooey texture with melty cheese pulls that are exciting and delicious.
  • Kosher salt
  • Fresh Cilantro – to garnish

How to roast poblano peppers

Roasting poblano peppers is a simple process that enhances their flavor and texture.

Roasted poblano peppers collage of steps.
  • Preheat the broiler: Adjust your oven rack to the highest position and preheat the broiler.
  • Prepare the peppers: Wash the poblano peppers and pat them dry with paper towels. Remove any stickers or debris.
  • Broil the peppers: Place the poblano peppers on a baking sheet. Place the baking sheet under the broiler and let the peppers roast.
  • Char the peppers: Allow the peppers to blister and char on all sides. You’ll hear them sizzle and pop as they roast. Use tongs to turn the peppers as needed to ensure even charring.
  • Steam the peppers: Once the peppers are charred on all sides, place them in a bowl and cover it with plastic wrap. Let the peppers steam for 5-10 minutes. This will help loosen the skins, making them easier to peel.
  • Peel the peppers: After steaming, the skins of the peppers should be easy to remove. Use your fingers or a knife to peel away the charred skin. If you prefer, you can leave some of the charred bits for added flavor.

Expert Tips

  • Mexican cheeses like Oaxaca, asadero, or Chihuahua cheese are traditionally used because they melt well and have a nice flavor, but they may be hard to find. You can also use other melting cheeses like Monterrey Jack or mozzarella (like I did). 
  • Use fresh, real cheese. Do not use pre-shredded, bagged cheese. The anti-caking agents will cause your queso to become a goopy blob. That is not what we want!
  • To keep hot for extended periods of time, like during a super bowl party, transfer chorizo dip to a crock pot/ slow cooker or place on a portable burner over low-heat.

Recipe Variations

Feel free to customize your hot cheese dip to suit your taste preferences. 

  • Add spices like cumin or chili powder
  • For additional heat, substitute strips of roasted serrano pepper, jalapeño peppers, or any of your favorite green chiles.
  • Add additional ingredients like sliced mushrooms or black beans
  • Substitute additional vegetables, or add sautéed mushrooms for the chorizo if you like.
  • Garnish with sliced green onions or chopped parsley if you are not a fan of cilantro.

Queso Flameado

Queso flameado, or “flamed cheese”, is a dish from northern Mexico made of hot melted cheese and spicy chorizo that is served flambé.

  • Prepare your queso fundido as usual in a skillet or baking dish.
  • Once the cheese is melted and bubbly, remove the skillet from the heat momentarily.
  • Pour a small amount of rum, tequila, or brandy over the melted cheese. Use caution and keep a safe distance from the flame when doing this.
  • Carefully ignite the alcohol with a long-reach lighter or a match. Be cautious, as the flames can flare up quickly.
  • Allow the flames to burn out naturally or carefully extinguish them by covering the skillet with a lid.
  • Once the flames have subsided, you can garnish and serve the queso fundido as desired.

Make-ahead and Storage

  • Cook the chorizo and vegetables ahead of time, store separately in the refrigerator, then quickly assemble and bake the dish when ready to serve.
  • Store cooled leftovers in an airtight container, in the refrigerator for up to 3-4 days.
  • Gently reheat leftover queso fundido over low heat on the stove, stirring occasionally until warmed through and the cheese is melted and creamy again. Avoid reheating it in the microwave, as this can cause the cheese to become rubbery.
