Cheese quesadillas
Crisp, pan-toasted flour tortillas stuffed with a melty mix of Monterey Jack and cheddar, plus a quick sauté of onion and jalapeño for extra flavor. This recipe makes 2 large quesadillas, cut into 8 wedges total. A little butter and oil help the tortillas brown evenly without burning while the cheese melts fully.

Estimated calories and US ingredient costs.
For more than 2 servings, cook quesadillas in batches in a 12-inch skillet rather than crowding the pan. Keep the heat near medium and add only a thin film of butter and oil between batches. If doubling, use a second skillet or hold finished quesadillas on a rack in a 200 F oven for up to 20 minutes so they stay crisp.

Ingredients
For 2 people
- 4 large flour tortillas
- 6 oz shredded Monterey Jack cheese
- 2 oz shredded sharp cheddar cheese
- 1 tbsp unsalted butter
- 1 tsp neutral oil
- 2 oz yellow onion, thinly sliced
- 1 oz jalapeño, seeded and finely chopped
- 1 tbsp chopped fresh cilantro
- 1 tbsp lime juice
- 1/4 tsp fine salt
Method
- Sauté the vegetables and mix the fillingSet a medium skillet over medium heat and add 1 tbsp unsalted butter and 1 tsp neutral oil. When the butter foams, add 2 oz thinly sliced yellow onion and 1 oz finely chopped jalapeño. Cook for 2 to 3 minutes, stirring, until the onion softens slightly. Transfer to a medium bowl and let cool for 1 minute, then add 6 oz shredded Monterey Jack, 2 oz shredded sharp cheddar, 1 tbsp chopped fresh cilantro, 1 tbsp lime juice, and 1/4 tsp fine salt. Toss well so the cheese is evenly coated and the filling is distributed without clumping.
- Build the first quesadillaLay 2 large flour tortillas flat on a work surface. Divide half of the filling over one half of each tortilla, leaving a narrow border at the edge so the filling does not spill out. Fold the empty half over the filling and press gently to flatten.
- Brown and melt the first quesadillaReturn the skillet to medium heat. Transfer one folded quesadilla to the skillet and cook for 2 to 3 minutes, pressing lightly with a spatula once or twice so the tortilla makes contact with the pan. Lift an edge to check that the underside is deep golden with a few darker spots before turning. If it is coloring too fast, lower the heat; if it looks pale after 3 minutes, raise the heat slightly.
- Flip and finish the first quesadillaTurn the quesadilla carefully and cook the second side for 2 to 3 minutes more, until the cheese is fully melted and the tortilla is crisp and evenly browned. Transfer to a cutting board and let it rest for 1 minute so the cheese sets slightly before slicing. If the skillet looks dry before the second quesadilla, add a very thin film of the remaining fat; do not let the tortillas fry in a puddle of oil.
- Cook the second quesadillaRepeat the folding and cooking with the remaining 2 tortillas and the rest of the filling. Keep the heat at medium to medium-low if the pan darkens quickly, because flour tortillas can go from pale to overbrowned fast once the skillet is hot. Aim for an even toasted exterior and a fully molten center.
- Slice and serveCut each quesadilla into 4 wedges with a sharp knife or pizza cutter. Serve immediately while the cheese is stretchy and the tortillas are crisp. For the cleanest slices, wipe the blade between cuts and angle the wedges so the browned side faces up on the plate.
Before you cook
What to get ready
Wide skillet, spatula, separate filling bowls and a clean towel for warmed tortillas.
Soften the onion and jalapeño before combining with shredded cheese.
If something needs adjusting
Cheese escapes into the pan
Leave a clear tortilla border and avoid excess filling; turn carefully once the first side sets.
A larger batch goes cold before serving
Prepare toppings first, keep tortillas covered briefly and assemble at the table rather than filling every tortilla in advance.
Store for later
Refrigerate perishable fillings separately from tortillas and cold toppings. Reheat cooked fillings to 165°F, then warm tortillas and assemble.
Refrigerate perishables within 2 hours, or 1 hour above 90°F. Keep the fridge at 40°F or below; use refrigerated leftovers within 3–4 days. USDA storage and reheating guidance.

Tips, swaps and questions
A little kitchen know-how
For the best browning, shred the cheese yourself or choose a dry pre-shredded blend that melts well. If the tortillas seem flimsy, warm them for 10 seconds in the dry skillet before filling so they fold without cracking. Letting the quesadillas rest for a minute after cooking helps the cheese settle and reduces filling spill when sliced.
Make it work for you
Swap the Monterey Jack and cheddar for an equal total amount of mozzarella, Oaxaca, or a mild Mexican melting cheese blend if you want a stretchier quesadilla. If you replace the onion with 2 oz diced roasted poblano, the flavor will be sweeter and the filling will be less sharp, so keep the skillet a little lower to avoid overbrowning before the cheese melts.
Use more of your yellow onion and butter in baccala alla vicentina.
How do I keep cheese quesadillas crisp instead of soggy?
Use a dry-to-moderate amount of fat, not a heavy slick of oil, and cook over medium heat so the tortilla has time to toast while the cheese melts. Avoid overfilling, because excess moisture from the filling can steam the tortilla. Slicing only after a brief rest also helps the interior set without softening the crust too much.
