Queso Fundido—which literally means “molten cheese” or “melted cheese”—is a hearty, endlessly customizable Mexican dish that unites aromatic sausage, sweet peppers, and an avalanche of oozy, stringy cheese, all baked together in a sizzling-hot skillet. This classic appetizer is a must-have at gatherings, game-day parties, and family celebrations where cheese-lovers unite for communal dipping bliss.

What Is Queso Fundido?

Queso Fundido is far more than an ordinary cheese dip. Traditionally served bubbling hot, it’s a skilletful of perfectly melted, stretchy cheese, often complemented by savory sausage or chorizo, sautéed onions, and peppers. The original Mexican version can sometimes be flambéed (set on fire at the table!), adding a sense of drama and smoky flavor. Whether kept simple or “dressed up” with a rainbow of toppings, Queso Fundido promises decadence in every scoop.

Ingredients for Classic Queso Fundido

This recipe for Queso Fundido calls for a handful of core components and can be personalized however you like.

  • 1/2 lb. Hot Breakfast Sausage or Chorizo: Spicy meat is traditional, but classic breakfast sausage imparts a savory richness. For more heat and complexity, try Mexican chorizo.
  • 1 medium Onion: Finely diced onion caramelizes beautifully for a subtle natural sweetness.
  • 2 small Bell Peppers: Any combination—green, yellow, red, or orange—adds crunch, sweetness, and visual flair.
  • 1 lb. Monterey Jack Cheese: Grated. For best results, use a cheese with excellent melting capabilities, such as Monterey Jack or mozzarella. Queso Quesadilla is another great Mexican choice.
  • Sprinkle of Chili Powder: For a little extra smokiness and mild heat.
  • 3 Roma Tomatoes: Diced tomatoes offer a touch of acid and freshness to balance the gooey richness.
  • 1/4 cup Cilantro: Finely chopped to garnish with herbal brightness.
  • Tortilla Chips: The perfect crunchy vehicle for scooping up bites of molten cheese.

Optional Extras and Variations

  • Other Cheeses: Oaxaca, mozzarella, queso asadero, or mozzarella-blend cheeses can be used for extra stretchiness.
  • Fresh or Pickled Jalapeños: For those seeking more heat.
  • Roasted Corn: Adds sweetness and texture.
  • Flambé: For an authentic restaurant touch, drizzle with a splash of tequila and carefully ignite.
  • Vegetarian Version: Omit the meat and use sauteed mushrooms for a hearty, umami-rich variation.

Step-By-Step Guide to Queso Fundido

Bring restaurant magic home with this simple, step-by-step approach:

1. Prep Your Vegetables

  • Finely dice a medium onion and two small bell peppers of your choice. Bright colors lend extra appeal to the finished dish.
  • Dice your Roma tomatoes and chop cilantro. Set these aside for garnishing.

2. Brown the Sausage (or Chorizo)

  • Crumble and cook the sausage or chorizo in a skillet over medium-high heat until fully browned.
  • Drain excess grease: Transfer the sausage to a paper towel-lined plate to wick away extra fat—this is important, since too much grease can interfere with cheese melting.
  • Optional: For a fiery version, briefly sauté a minced jalapeño with the sausage.

3. Sauté the Onions and Peppers

  • Pour off any remaining grease from the skillet, then add the diced onions and peppers.
  • Cook for about 5 minutes over medium-high heat, or until softened and starting to turn golden brown.

4. Grate and Combine the Cheese

  • Grate a full pound of Monterey Jack (or your melting cheese of choice). Grating fresh cheese rather than buying pre-shredded ensures the ultimate gooey melt.
  • If using, add a mix of queso quesadilla or mozzarella for even more stretch.

5. Layer and Bake

  • In a small oven-safe skillet (6-7 inches is ideal), layer the cooked sausage, sautéed veggies, and all but a handful of the grated cheese.
  • Sprinkle remaining cheese and a dash of chili powder on top for a flavorful crust.
  • Bake at 400°F (204°C) just until the cheese is bubbling, melted, and slightly browned at the edges—about 8 to 10 minutes.

6. Garnish and Serve

  • Top immediately with fresh diced tomatoes and a generous shower of chopped cilantro.
  • Serve right away with a mountain of tortilla chips or warm flour tortillas.

Best Cheese Types for Queso Fundido

The real secret to an irresistible Queso Fundido is using the best cheese for maximum stretch. Here’s how popular choices stack up:

OaxacaCreamy, slightly tangyExceptional stringy meltTraditional Mexican fundido
MozzarellaMild, milkyHigh stretch, neutral flavorSubstitute or blend-in
Queso AsaderoButtery, subtleExcellent meltBlending with sharper cheeses

Tips for Perfect Queso Fundido Every Time

  • Use freshly grated cheese for optimal melting and creamy texture—pre-shredded cheese can contain anti-caking agents that inhibit meltiness.
  • Small skillet, fast serving: Bake Queso Fundido in a smaller skillet so it stays hotter, disappearing before the cheese can begin to firm up.
  • Don’t overbake: Watch closely—overcooking can cause the cheese to separate or become rubbery.
  • Serve immediately: Queso Fundido is best moments after emerging from the oven while molten and bubbly.
  • Customize toppings: Any combination of tomatoes, roasted peppers, or even diced avocado works as a finishing touch.

Creative Variations and Serving Suggestions

  • Breakfast Queso Fundido: Top with scrambled eggs and serve with warm tortillas for a brunch-worthy meal.
  • Mushroom Fundido: Sauté sliced mushrooms with onions and swap out the meat for a vegetarian twist.
  • Chorizo & Poblanos: Use spicy Mexican chorizo and roasted poblano peppers for a smoky-flavored fundido.
  • Keto-Friendly: Serve with sliced bell peppers or low-carb veggies instead of chips.
  • Taco Topping: Spoon leftover fundido atop tacos or nachos for cheesy decadence.

Frequently Asked Questions (FAQ)

What skillet is best for Queso Fundido?

A small, oven-safe cast iron skillet (6-7 inches) is ideal. It keeps the cheese molten longer and adds a rustic presentation.

Can I make Queso Fundido ahead of time?

It’s best served straight from the oven, but you can prep the sausage and veggie mixture in advance. Assemble and bake the cheese just before serving.

Can I flambé Queso Fundido at home?

Yes! Drizzle a tablespoon of tequila over the cheese, carefully ignite with a long lighter, and let the flames subside before serving. Always use caution.

How do I reheat leftovers?

Reheat gently in a low oven or microwave until molten again. Stir well, and serve immediately—it may lose stretchiness over time but will still taste delicious.

Is Queso Fundido gluten-free?

Yes, as long as your sausage and other ingredients are certified gluten-free. Always check packaging for additives.

Expert Tips and Troubleshooting

  • Cheese separation? If the fat separates from the cheese, add a splash of milk or cream, then stir vigorously to bring everything back together.
  • Cheese too stiff? Bake less and serve piping hot. Overbaked cheese firms up as it cools.
  • Skillet stuck on cheese? Soak the pan in hot water before washing.

Serving Queso Fundido: Final Touches

Garnish with your favorite toppings—fresh tomatoes, cilantro, or even diced avocado—and serve immediately with crispy tortilla chips or warm flour tortillas. Dip, scoop, and enjoy the essence of cheese-laden comfort food.
