Step-by-Step Instructions
Preparing the Perfect BBQ Chicken
- If using raw chicken, season 1 pound boneless breasts with salt, pepper, and garlic powder, then grill over medium-high heat for 6-7 minutes per side until cooked through.
- Let grilled chicken rest for 5 minutes, then shred into bite-sized pieces using two forks, creating texture that distributes evenly throughout quesadilla.
- In a medium bowl, combine shredded chicken with ¼ cup barbecue sauce, tossing to coat evenly while ensuring every piece is flavored but not oversauced.
- If using rotisserie chicken, remove skin and shred meat from bones, discarding any cartilage or tough pieces that could affect texture.
- Taste seasoned chicken and adjust flavors as needed, adding more barbecue sauce for intensity or seasonings for depth according to preference.
- Set prepared chicken aside while preparing other components, keeping it at room temperature for even cooking during quesadilla assembly.
Creating Caramelized Onion Perfection
- Heat 1 tablespoon oil in large skillet over medium heat, then add 1 large sliced yellow onion, cooking slowly for optimal caramelization.
- Cook onions for 15-20 minutes, stirring occasionally, until they become golden brown and sweet, developing deep flavor complexity through proper caramelization.
- Season cooking onions with pinch of salt and pepper, which helps draw out moisture and accelerates the caramelization process for better results.
- If onions brown too quickly, reduce heat and add splash of water to prevent burning while maintaining steady caramelization progress.
- Properly caramelized onions should be golden brown, sweet, and jammy in texture, adding crucial flavor depth to the finished quesadilla.
- Remove caramelized onions from heat and set aside, keeping them warm if possible for optimal integration into the assembled quesadilla.
Preparing the Cheese and Assembly Components
- Grate 2 cups sharp cheddar and 1 cup Monterey Jack cheese using large holes of box grater, ensuring fresh cheese for superior melting.
- Combine grated cheeses in bowl and toss gently to distribute evenly, creating balanced flavor profile throughout each quesadilla portion.
- Prepare any optional vegetables like bell peppers or jalapeños by slicing thinly and removing excess moisture that could affect texture.
- Have all filling components arranged near cooking area for efficient assembly that prevents ingredients from cooling while working.
- Ensure tortillas are at room temperature and check for any tears or weak spots that might cause filling to leak during cooking.
- Prepare clean workspace with all necessary tools including spatula, plates for serving, and cutting board for final slicing presentation.
Assembling the Ultimate Quesadilla
- Place one large tortilla on clean work surface and spread thin layer of barbecue sauce over entire surface, leaving small border around edges.
- Distribute half of cheese mixture evenly over sauced tortilla, creating base layer that will help hold other fillings in place during cooking.
- Add seasoned barbecue chicken pieces over cheese, distributing evenly to ensure every slice contains adequate protein and flavor distribution.
- Top chicken with caramelized onions and any optional vegetables, spreading evenly while maintaining manageable thickness for proper cooking.
- Sprinkle remaining cheese over all fillings, creating top layer that will melt and bind ingredients together during cooking process.
- Top with second tortilla and press gently around edges to seal, ensuring fillings stay contained while allowing for expansion during cooking.
Achieving Perfect Golden Crispiness
- Heat large skillet or griddle over medium heat, ensuring even temperature distribution for consistent browning and proper cheese melting.
- Lightly brush or spray cooking surface with oil to prevent sticking and promote even browning of tortilla exterior during cooking.
- Carefully transfer assembled quesadilla to hot skillet, using spatula to support structure and prevent filling from shifting or spilling.
- Cook for 3-4 minutes on first side until golden brown and crispy, resisting urge to move or flip prematurely for optimal results.
- Using large spatula, carefully flip quesadilla and cook additional 3-4 minutes until second side is golden and cheese is fully melted throughout.
- Check for doneness by gently pressing center—cheese should be completely melted and tortillas should be crispy and golden brown.
Final Presentation and Serving Excellence
- Remove cooked quesadilla from heat and transfer to cutting board, allowing it to rest for 2-3 minutes before cutting to prevent cheese from oozing out.
- Using sharp knife or pizza cutter, slice quesadilla into 6-8 triangular wedges, ensuring clean cuts that maintain attractive presentation and filling distribution.
- Arrange cut wedges on serving platter with points facing outward, creating appealing fan pattern that showcases golden color and melted interior.
- Garnish with fresh chopped cilantro, dollops of sour cream, and additional barbecue sauce for dipping, enhancing visual appeal and flavor options.
- Serve immediately while cheese is still melted and tortillas maintain optimal crispy texture for best eating experience and satisfaction.
- Provide small bowls of various sauces and garnishes, allowing guests to customize their quesadilla experience according to personal preferences and heat tolerance.

Frequently Asked Questions
How do I prevent my quesadilla from getting soggy?
Use thick barbecue sauce and don’t overfill with wet ingredients. Pat any vegetables dry before adding them, and avoid using too much sauce—just enough to flavor the chicken. Cook over medium heat to ensure the tortilla crisps up properly while the cheese melts. Also, let the quesadilla rest briefly before cutting to allow any steam to dissipate.
What’s the best way to flip a quesadilla without spilling the filling?
Use a large, wide spatula and work quickly but carefully. Make sure the bottom is properly set and golden before attempting to flip. You can also use the “plate method”—slide the quesadilla onto a large plate, then flip the plate over the pan and slide it back in. Some cooks prefer using two spatulas for extra support.
Can I make quesadillas ahead of time?
You can prepare the filling components ahead of time, but it’s best to assemble and cook quesadillas just before serving for optimal crispiness. If you must make them ahead, store cooked quesadillas in the refrigerator and reheat in a dry skillet over medium heat for 2-3 minutes per side, or in a 350°F oven for 5-7 minutes.
