Make smoky queso fundido with roasted zucchini, bell pepper, portobello mushroom, and bubbling cheese for an easy gluten-free appetizer.
Rich, colorful, and wonderfully satisfying, this Smoky Queso Fundido with Mixed Vegetables Recipe transforms a handful of simple ingredients into an irresistible hot appetizer. Melted Oaxaca or Monterey Jack cheese provides the gooey base, while roasted zucchini, bell pepper, and portobello mushroom bring savory flavor, tender texture, and vibrant color to every scoop.
Roasting the vegetables before arranging them over the cheese is the key to the dish. High heat concentrates their natural flavor, encourages lightly charred edges, and prevents the finished queso from becoming watery. You can prepare the vegetables and melt the cheese on a barbecue for a smoky outdoor version or use the oven for a convenient indoor option. Both methods produce a bubbling skillet that is ideal for game day, taco night, family gatherings, and casual entertaining.
This vegetable queso fundido is naturally gluten-free when the seasoning and serving accompaniments are appropriately labeled. Offer it straight from the warm cast iron skillet with certified gluten-free tortilla chips or warm gluten-free tortillas. Because melted cheese begins to firm as it cools, gather everyone before the skillet reaches the table and enjoy the queso while it is hot, stretchy, and at its most inviting.
Prep Time: 15 minutes
Cook Time: 20 minutes
Total Time: 35 minutes
Yield: 4 to 6 servings
Ingredients
1 medium zucchini, halved lengthwise
1 bell pepper of any color, halved and seeded
1 large portobello mushroom, stem removed
1 tablespoon olive oil
2 1/2 cups freshly grated Oaxaca cheese or Monterey Jack cheese
1 teaspoon Mexican seasoning or taco seasoning
Fresh chopped cilantro, for garnish
Sliced jalapeños, optional
Certified gluten-free tortilla chips or warm gluten-free tortillas, for serving
Directions
Step 1: Preheat the Grill or Oven
For the barbecue method, preheat the grill to medium-high heat and prepare an area for indirect heat. For the oven method, preheat the oven to 425°F. Have a baking sheet ready if roasting the vegetables indoors.
Use a 10-inch cast iron skillet for melting and serving the cheese.
Step 2: Prepare the Vegetables
Brush the cut zucchini, bell pepper halves, and portobello mushrooms lightly and evenly with the olive oil.
Coating the vegetables helps them brown, prevents sticking, and encourages the lightly smoky flavor that complements the rich cheese.
Step 3: Roast the Vegetables
Place the vegetables directly on the grill over medium-high heat. Alternatively, arrange them in a single layer on the baking sheet and place them in the preheated oven. Roast for 12 to 15 minutes, turning once if grilling, until the vegetables are tender and lightly charred. Remove them from the heat and let them cool for several minutes, just until they are comfortable to handle.
Step 4: Slice the Vegetables
Cut the roasted zucchini, bell pepper, and portobello mushroom into bite-sized strips. Keep the pieces substantial enough to provide texture but small enough to scoop easily with a tortilla chip. Set the sliced vegetables aside while preparing the cheese.
Step 5: Season the Cheese
Spread the freshly grated Oaxaca cheese or Monterey Jack cheese evenly in the cast iron skillet. Sprinkle the Mexican seasoning or taco seasoning across the surface so its flavor is distributed throughout the melted cheese rather than concentrated in one area.
Step 6: Melt the Cheese
Place the skillet over indirect heat on the barbecue or transfer it to the 425°F oven. Cook for 8 to 10 minutes, watching carefully near the end, until the cheese is completely melted, bubbling around the edges, and beginning to turn lightly golden. The exact melting time may vary slightly depending on the cheese and the heat of the grill or oven.
Step 7: Add the Roasted Vegetables
Carefully arrange the roasted vegetable strips over the melted cheese. Return the skillet to the indirect side of the grill or to the oven for 2 to 3 minutes. Heat just until the vegetables are warmed through and nestled into the bubbling cheese.
Step 8: Garnish and Serve
Carefully remove the hot skillet from the heat and place it on a heat-safe trivet. Sprinkle fresh chopped cilantro over the queso and add sliced jalapeños if desired. Serve immediately with certified gluten-free tortilla chips or warm gluten-free tortillas for scooping. Remind guests that the cast iron skillet and its handle will remain very hot.
Notes
Oaxaca cheese delivers the long, stretchy pull commonly associated with queso fundido. Monterey Jack is a creamy, accessible substitute that melts smoothly. For the most even result, grate the cheese fresh rather than using packaged shredded cheese, which may contain anti-caking ingredients that affect melting.
The barbecue gives the vegetables a pronounced smoky character, while the oven offers reliable, convenient roasting in any weather. When grilling, move the cheese skillet to indirect heat so the bottom does not scorch before the top has melted.
The vegetables should be tender and lightly charred but not overly soft. Allowing them to cool briefly before slicing makes them easier to handle. If they release visible moisture after roasting, blot them gently before placing them over the cheese.
Check the label on taco or Mexican seasoning because some blends may contain gluten or be processed where cross-contact is possible. Use certified gluten-free tortilla chips or appropriately labeled gluten-free tortillas when preparing the dish for someone with celiac disease or gluten sensitivity, and prevent cross-contact during preparation and serving.
For optional variety, add roasted onion, poblano pepper, corn, or sliced cherry tomatoes. These additions can complement the original vegetables, but avoid overloading the skillet because too many toppings can cool the cheese and make the queso difficult to scoop.
Serve queso fundido as soon as it leaves the heat. A cast iron skillet retains warmth longer than many baking dishes, but the cheese will naturally become firmer as it cools. If needed, return the skillet briefly to gentle heat to loosen the cheese, watching closely to prevent scorching.
This appetizer pairs well with tacos, grilled chicken, fajitas, carne asada, or a larger Mexican-inspired spread. The recipe yields 4 to 6 appetizer servings, depending on the other foods offered and the size of each portion.
Refrigerate leftovers in an airtight container for up to 2 days. Reheat them gently in a 325°F oven until the cheese is fully hot and melted again. Use care with a chilled cast iron skillet and allow it to lose its refrigerator chill before placing it in a hot oven to reduce the risk of thermal shock.
