Stovetop method below. For 4 more methods, including Air-Fryer, Toaster Oven, Microwave, and more, check out the post above.
Heat a large skillet to medium heat. Spread half the butter across the surface of the skillet, allowing it to melt and thoroughly coat the skillet.
Place 1 large tortilla on the skillet. Sprinkle with cheese.
Once cheese is melted, add the second tortilla.
Cook for 2-4 minutes, pressing down with a heatproof spatula to adhere the top tortilla to the melting cheese, creating a quesadilla. Mine took 3 ½ minutes.
The quesadilla is ready for the next step when the cheese is melted and the bottom tortilla’s underside is golden brown.
Transfer the quesadilla to a plate. Add the remaining half of the butter to the skillet, using a heatproof utensil to move it around and coat it thoroughly.
Place the quesadilla back onto the skillet, ensuring that it’s flipped over to cook the un-crisped side.
Again, use the spatula to press down on the quesadilla to create an evenly golden brown surface. Cook until desired crisp-level is reached, about 1-2 minutes. Mine took just 1 more minute since the pan was nice and hot!
Sprinkle with salt to bring out the buttery and cheesy flavor.
Storing Instructions: Cool completely, then store cheese quesadillas in an airtight container in the refrigerator for 1-3 days. Before serving, reheat on the skillet or in the microwave until the cheese is re-melted.
