Crispy, golden flour tortillas loaded with melted cheese and your choice of fillings. The ultimate 10-minute budget meal — endlessly customisable, perfectly satisfying, and loved by everyone.

Quesadillas (pronounced 'keh-sah-dee-yahs', from the Spanish 'queso' meaning cheese) are among the most beloved everyday foods of Mexican and Mexican-American cooking — flour tortillas filled with cheese and cooked in a pan until golden and crispy, with the cheese inside melted into a gloriously gooey interior. In their simplest form they require only tortillas and cheese. At their most complex, they can hold any combination of proteins, vegetables, and seasonings.
Quesadillas take 10 minutes, cost under £2 per person, require almost no skill, and produce a result that is genuinely delicious. The technique is simple enough for complete beginners but rewards a few techniques — medium heat, cheese on both sides, resting before slicing — that elevate them from a snack to a proper satisfying meal.
Quesadillas are perfect for quick lunches, fast weeknight dinners, casual entertaining, feeding children, or late-night snacking. They work as a starter cut into small triangles, a main course with a salad alongside, or a sharing dish with dips and salsas in the middle of the table.
Grate cheese from a block for the best melt. Layer cheese on both sides of the filling. Use medium heat throughout. Press gently with a spatula during cooking. Rest 30 seconds before slicing.
Large flour tortillas provide a neutral, slightly chewy wrapper that becomes golden and crispy when pan-fried. The 25cm size is ideal for a half-moon folded quesadilla. Corn tortillas can be used for a more traditional flavour but are smaller and more fragile.
The defining filling — the cheese must melt completely into a smooth, stretchy interior. Grating your own from a block is essential for the best melt. Monterey Jack is mild and supremely melty; Cheddar adds flavour but can be slightly oilier.
The most common and best-matching filling alongside cheese — they add plant-based protein, fibre, and a creamy, earthy flavour that complements the melted cheese perfectly. Season with cumin and smoked paprika before adding.
The spice combination that gives quesadillas their characteristic Mexican-spiced character. Added to the filling, they season the cheese and vegetables with warmth and smokiness.
Corn tortillas can replace flour tortillas for a more traditional, gluten-free option. Any good-melting cheese (Gouda, Mozzarella, Gruyère, Emmental) works in place of Cheddar. Refried beans can replace black beans for a more traditional Mexican filling. Vegan cheese alternatives melt with varying success — brands vary significantly in their melt quality.
Grate the cheese if not pre-grated. Prepare any optional fillings — slice the pepper thinly, drain and rinse the beans, slice the spring onions. If using spices, mix them with a small pinch of salt in a bowl and set aside. Having everything ready before cooking ensures the quesadilla is assembled quickly and the cheese melts evenly before the tortilla over-browns.
Place a tortilla flat on a work surface. Sprinkle half of the grated cheese evenly over one half of the tortilla, leaving a 1cm border at the edge. Add any fillings on top of the cheese in a thin, even layer. Scatter the remaining cheese on top of the fillings. Fold the bare half of the tortilla over the filled half to create a half-moon shape. Press down gently.
Heat a large non-stick or cast-iron frying pan over medium heat. Add just a tiny drizzle of oil or a small knob of butter and spread to coat. Place the folded quesadilla in the pan. Cook for 2–3 minutes until the bottom tortilla is golden and crispy and the cheese has started to melt. Carefully flip using a wide spatula and cook the second side for 2 minutes until golden.
Remove from the pan and rest on a board for 30 seconds — this allows the melted cheese to set slightly so the quesadilla holds together when sliced. Cut into 3–4 wedges with a sharp knife or pizza wheel. Serve immediately with sour cream, salsa, or guacamole.
Techniques that separate good from great
The common mistake is putting all the cheese on one side of the filling. When you fold the tortilla and the quesadilla is cooked, the cheese is only on one side of the filling and the other side is dry. Placing cheese on the bottom, adding fillings, then adding more cheese on top of the fillings means the entire inside becomes unified by melted cheese that acts as an adhesive holding everything together.
Quesadillas are a classic victim of too-high heat. The tortilla is thin and browns quickly — if the heat is too high, the outside is dark and crispy before the inside cheese has melted. Medium heat gives the tortilla time to colour gradually while the cheese inside heats all the way through to a fully melted, gooey interior. If the tortilla is browning before you can see the cheese melting at the edges, reduce the heat.
Slicing a quesadilla immediately after removing from the pan releases all the molten cheese, which pools out onto the board and leaves the inside of the quesadilla dry and less satisfying. A 30-second rest allows the cheese to partially set — it remains molten and stretchy but stays inside the quesadilla when sliced and served.
A well-seasoned cast-iron pan without any added fat or oil produces the crispiest, most evenly browned tortillas because it maintains heat perfectly and the dry surface maximises contact between the tortilla and the hot pan. Non-stick pans with a tiny amount of oil also work well, but the cast-iron method produces a noticeably superior crunch.
Different ways to make this dish your own
Fill with 150g of shredded cooked chicken seasoned with cumin, smoked paprika, and garlic powder. Add a tablespoon of salsa inside for moisture. The most popular quesadilla variation in Mexican-American cooking.
Fill with scrambled eggs, diced cooked bacon or sausage, and cheese. Serve with hot sauce for a fast, substantial morning meal.
Fill with leftover pulled pork or shredded slow-cooked beef, pickled jalapeños, and Cheddar. The sweet, smoky pork with sharp cheese is an exceptional combination.
Fill with mashed roasted sweet potato and seasoned black beans. Use vegan cheese or omit altogether — the filling is substantial enough without it. Season generously with cumin, smoked paprika, and lime.
Perfect pairings to complete the meal
The classic accompaniment — cool, tangy sour cream contrasts with the hot, crispy quesadilla and provides a creamy richness that complements the cheese and spices.
The acidity and freshness of chopped tomato salsa cuts through the richness of melted cheese and crispy tortilla, providing a bright, clean counterpoint.
Creamy, fresh avocado guacamole is the third essential accompaniment alongside sour cream and salsa — the avocado fat adds richness and its green freshness balances the warm, heavy quesadilla.
For heat lovers — the vinegary, spicy jalapeño is the perfect flavour contrast to mild, melted cheese.
Keep it fresh and plan ahead
Store cooked quesadillas wrapped in foil for up to 2 days. The tortilla will soften as it sits.
Freeze cooked quesadillas individually wrapped in parchment then foil for up to 2 months. Reheat directly from frozen in a pan.
Assemble uncooked quesadillas up to 4 hours ahead, wrap in cling film, and refrigerate. Cook as directed when ready to serve.
Reheat in a dry pan over medium heat for 2 minutes per side until the tortilla is crispy again and the cheese is melted. Avoid the microwave — it makes the tortilla soft and rubbery.
