The contrast is what makes it addictive—the silky, stringy pull of Oaxaca (or Monterey Jack) against the bite of pepper jack, the crunchy house-grilled tortilla wedges, and the vegetal complexity that comes when poblanos are blistered on the grates and then peeled and folded back in. Because it’s finished in a skillet right on the grill, the whole thing picks up a faint smoke note that store-bought queso just can’t replicate. What separates this version from a run-of-the-mill dip is attention to texture and timing: rendering the chorizo until the edges brown, steaming the poblanos for easy peeling, and using a two-zone fire so the cheese melts without scorching while you still create a golden socarrat if you like. It’s forgiving to make ahead—the chorizo base can be prepared a day early—yet dramatic to present straight from the cast-iron. Bring it to the table hot, keep a small skillet on the cooler side of the grill for reheats, and you’ve got a hands-off, high-reward centerpiece for a late-summer party. ## Recipe Information - Prep Time: 25 minutes - Cook Time: 30 minutes - Total Time: 55 minutes - Servings: 6 - Difficulty: Medium - Category: Grilling ## Ingredients ### Set up the grill and render the chorizo base - 3 tbsp extra-virgin olive oil - 8 oz Spanish chorizo (casing removed) or crumbled spicy pork chorizo - 1/2 medium medium yellow onion, finely chopped - 2 cloves garlic cloves, minced - 1 tsp smoked paprika (pimentón) ### Char the poblanos and add to the skillet - 2 pc poblano peppers ### Layer the cheeses and melt on the grill - 8 oz Oaxaca or Monterey Jack cheese, shredded - 4 oz pepper jack or sharp cheddar, shredded ### Grill the tortilla chips - 12 pc small corn tortillas ### Garnish and serve hot - 1/4 cup fresh cilantro, chopped (for garnish) ## Instructions ### 1. Set up the grill and render the chorizo base Create a two-zone fire: one side medium-high direct heat (about 400°F/200°C) and the other a medium indirect zone. Heat a 10–12" cast-iron skillet over direct heat, add the olive oil and crumbed chorizo and sear 6–8 minutes, stirring occasionally, until well browned and the fat renders. Add the chopped onion, minced garlic and smoked paprika and cook 3–4 minutes more until the onion is softened. (Make-ahead: you can cook the chorizo base up to 24 hours ahead—cool, refrigerate and rewarm in the skillet on the grill before finishing.) ### 2. Char the poblanos and add to the skillet Place the poblanos directly on the hot grates and rotate with tongs every 2–3 minutes until evenly blackened, 8–10 minutes total. Transfer to a bowl, cover with plastic or a lid to steam for 10 minutes, then peel, seed and dice the poblanos and fold them into the chorizo-onion mixture. Return the skillet briefly to the direct zone to marry flavors for 1–2 minutes if needed, then move it to the indirect zone to prepare for melting. ### 3. Layer the cheeses and melt on the grill Evenly scatter the shredded Oaxaca (or Monterey Jack) and the pepper jack (or cheddar) over the chorizo–poblano mixture in the skillet. Place the skillet over the indirect zone, close the lid and let the cheeses melt and bubble for 6–10 minutes until fully melted and starting to brown at the edges. For a touch of socarrat (golden blistering), move the skillet back over direct heat for 1 minute—watch closely to avoid burning. ### 4. Grill the tortilla chips Working in batches, brush both sides of the corn tortillas lightly with a little olive oil (you can reuse oil from the skillet if desired) and cut each into 6 wedges. Grill the wedges over direct heat 1½–2 minutes per side until crisp and blistered. Transfer to a paper bag and salt immediately; chips can be made an hour ahead and stored in a paper bag at room temperature, or re-crisped for 30–60 seconds on the grates before serving. ### 5. Garnish and serve hot Top the bubbling queso fundido with the chopped cilantro (and optional sliced scallions or a squeeze of lime). Bring the skillet directly to the table or keep warm on the cooler side of the grill so guests can dip. Serve with the grilled tortilla chips—plan on about 1/2 cup of dip per person and replenish chips as the crowd grazes. Serving tip: keep an extra small skillet warming on the indirect side for quick reheats if you expect guests over several hours. ## Nutrition Estimated nutrition per serving (2 tacos): - Calories: 522 kcal - Protein: 22.4 g - Carbohydrates: 29.2 g - Fat: 35.9 g - Saturated Fat: 15.3 g - Trans Fat: 0.3 g - Fiber: 4 g - Sugar: 1.9 g - Added Sugars: 0 g - Cholesterol: 76 mg - Sodium: 671 mg - Potassium: 359 mg - Calcium: 472 mg - Iron: 1.8 mg - Vitamin D: 1 mcg ## Tips ### Render Chorizo Thoroughly Cook the crumbled chorizo until the edges are nicely browned and most fat has released; that browning builds flavor and prevents a greasy final dip. ### Steam Poblanos For Easy Peeling After charring, trap the poblanos in a covered bowl for 10 minutes to loosen the skin—peeling under-running water removes char bits without losing flesh. ### Shred Cheese Fresh Buy blocks and shred them yourself so the cheese melts evenly; pre-shredded blends contain anti-caking agents that can make the melt grainy. ### Use Two-Zone Grill Melt the cheese over the indirect zone to avoid burning, then flash over direct heat for just 30–60 seconds if you want a blistered edge. ### Crisp Chips Last Grill tortilla wedges until they’re blistered and then store in a paper bag at room temperature to keep them crisp; re-crisp on the grates for 30–60 seconds if needed. ## Variations and Substitutions ### Vegetarian 'Chorizo' Swap Replace the pork chorizo with diced, sautéed king oyster mushrooms tossed with smoked paprika and a splash of soy sauce for umami and meaty texture. ### Lower-Heat Version Use mild chorizo or omit the pepper jack and add a pinch of smoked paprika for warmth without aggressive heat, and serve with lime wedges to brighten flavors. ### Smoky Chipotle Twist Stir in one minced chipotle in adobo with the onions for deeper smoke and heat; start with half a pepper and taste before adding more. ### Oven-Finish Option If you don’t have a grill, assemble in a cast-iron skillet and finish under a 425°F broiler or in a 400°F oven until cheeses bubble and brown at the edges. ## Notes This smoky, melty queso fundido is built for grazing—make the chorizo and char the poblanos ahead of time to minimize grill work at the party. It holds and reheats beautifully in the skillet, making it ideal for a relaxed Labor Day gathering. ### Storage and Make-Ahead Store leftover queso fundido in an airtight container in the refrigerator for up to 3 days; separate the chips and keep them in a paper bag at room temperature to preserve crunch. Reheat the dip in a cast-iron skillet over low heat on the stove or on the grill’s indirect zone, stirring in a tablespoon of milk or cream if it looks tight to restore a silky texture. Re-crisp chips for 30–60 seconds on the hot grates or 3–5 minutes in a 375°F oven. ### Serving Suggestions Serve the skillet on a wooden board with lime wedges, pickled red onion, and extra chopped cilantro for brightness; offer bowls of salsa verde and sliced radishes for textural contrast. Pair with a crisp Mexican lager or a mezcal margarita—the beer cuts the richness while mezcal echoes the smoky notes—and round the plate out with grilled elote or a simple jicama–orange salad for a refreshing counterpoint. ## Frequently Asked Questions ### Do I need raw chorizo or cured Spanish chorizo? For this recipe use fresh (Mexican-style) chorizo that crumbles and renders fat when cooked; cured Spanish chorizo is firm and sliced, and won’t render in the same way or integrate into the melted cheese. ### How do I prevent the queso from becoming greasy? Spoon off excess rendered fat from the chorizo before adding the cheese and use a mix of high-moisture melters like Oaxaca/Monterey Jack; rewarming gently over indirect heat avoids separation that comes from overheating. ### Can I char poblanos without a grill? Yes—char under a hot broiler, on a gas burner, or directly over a gas flame, then steam and peel the skins the same way described in the recipe. ### What’s the best way to reheat the dip for a later serving? Rewarm on the grill’s indirect side or in a skillet over low heat, stirring occasionally and adding a tablespoon of milk or cream if the cheese tightens; avoid the microwave to prevent graininess. ### Can store-bought tortilla chips be used? Absolutely—use high-quality thick corn chips if you need convenience, but grilling fresh tortillas adds smoky char and a sturdier wedge for scooping the molten cheese. ### How long can I make the chorizo base ahead? You can cook the chorizo, onion and garlic up to 24 hours ahead: cool, refrigerate, then reheat briefly in the skillet on the grill before adding poblanos and cheese. ## Related Recipes and Guides - [Tandoori Yogurt Marinated Grilled Chicken (Tandoori Style on the Grill)](https://www.topshelf.recipes/recipes/tandoori-yogurt-marinated-grilled-chicken) - [Labor Day Grilled Lobster Rolls with Charred Scallion Brown Butter & Lemon‑Herb Aioli](https://www.topshelf.recipes/recipes/labour-day-grilled-lobster-rolls-charred-scallion-brown-butter-lemon-herb-aioli) - [Bulgogi Smash Burger](https://www.topshelf.recipes/recipes/bulgogi-smash-burger) - [Campfire‑Smoked Potato Salad with Mustard‑Bacon Vinaigrette — A Labor Day Grilling Side for Steak](https://www.topshelf.recipes/recipes/campfire-smoked-potato-salad-mustard-bacon-vinaigrette) - [Hanger Steak with Shallot Sauce](https://www.topshelf.recipes/recipes/hanger-steak-with-shallot-sauce) - [Grilled Pineapple Upside-Down Cake](https://www.topshelf.recipes/recipes/grilled-pineapple-upside-down-cake) - [Trending Labor Day Steak Finishes](https://www.topshelf.recipes/articles/trending-labor-day-steak-finishes) - [7 Day Labor Day Drink Prep](https://www.topshelf.recipes/articles/7-day-labor-day-drink-prep) - [Hot‑Swap Labor Day Menus](https://www.topshelf.recipes/articles/labor-day-hot-swap-menus-2026)
