It has 10 tortillas, a pound of seasoned ground beef, a can of beans, loads of veggies, and a pound of cheese.  Whether you make it for a party or quick meals ready to go for the week (the individual squares reheat really well), this is definitely worth the work and is an impressive finished dish! 

Why Make a Quesadilla on a Sheet Pan?

Making one quesadilla isn’t a particularly hard task. Put a tortilla in a hot skillet with some cheese and filling and fold it over itself. Get the tortilla crispy and the cheese melted and you’re in quesadilla business. But, if you ever try to make, say, four quesadillas at once, you’ll hit a problem. It’s tricky to make them all and keep them warm.  Making a large single quesadilla on a sheet pan solves this problem. It’s a little more work up front, but once you have the quesadilla in the oven, you can sit back and wait for the deliciousness to be done! 

Favorite Fillings for Sheet Pan Quesadillas

In theory you could fill this large quesadilla with anything you might put in a single quesadilla. Here are the options I went with for this version!  Meats : For ease, I chose lean ground beef. You don’t want too much fat in the filling. Of course, you could also use cooked chopped chicken or even pulled pork for a filling option. If you want to make these vegetarian, leave out the meat and double the beans! Cheese: I kept it simple and used a Mexican blend for my cheese layers. You could just use cheddar cheese if that’s your preference. Monterey Jack or pepper jack would work great as well.  Beans: I definitely think you need some beans in this to help bulk up the filling. Veggies: I always love an onion and pepper in my quesadilla filling. Other options? Corn? Sure! Mushrooms? Sure! 

Choosing Tortillas for Your Giant Quesadilla

I would only use flour tortillas for these quesadillas. They are more pliable than corn tortillas and come in sizes that work for your pan. You can either use the 10-inch size tortillas or the 12-inch size tortillas. You will need at least 10 of the smaller ones and maybe an extra to fill any gaps. 

Making a Smaller Version

Maybe you wish to make a scaled-down quesadilla. No problem! You could make a smaller version in a 9 x 11-inch baking sheet with 2/3 of the filling, or use an 8 x 8-inch baking dish and cut everything in half. 

What to Serve with This Giant Quesadilla

This quesadilla is a meal on its own, but I do recommend serving it with salsa, sour cream, and guacamole. Good for dipping!

2 tablespoons olive oil 1 pound lean ground beef 1 yellow onion, cored and chopped 1 red pepper, cored and chopped 1 (15-ounce) can black beans, drained and rinsed 1 (5-ounce) can mild green chiles 3 tablespoons taco seasoning, plus more to taste 1/2 teaspoon kosher salt, plus more to taste 1/2 teaspoon black pepper 1/4 cup water Cooking spray 10 medium (10-inch) flour tortillas 16 ounces grated cheddar or Mexican blend cheese

For serving

Salsa Sour cream Guacamole

Add the taco seasoning, salt, pepper, and 1/4 cup of water. Continue to cook until water evaporates and the seasonings are evenly distributed, another 3-4 minutes. Remove from heat. Taste and adjust seasonings with more salt or taco seasoning, if desired. Add about 1/3 of the cheese to the bottom of the tortillas. Then spread out your cooked quesadilla filling all the way to the edges of the pan. Top with the remainder of the cheese. Place 2 more tortillas in the middle and fold tortillas over the edges to cover the filling. It’s okay if there are some small holes in the top. If you want to perfectly cover them, you can cut apart a new tortilla and use it to patch the holes in the top of the quesadilla.  Lightly spray the top of the quesadilla with cooking spray. Place a second, slightly smaller, sheet pan or baking dish on top of the quesadilla with foil in between the quesadilla and sheet pan. Serve the quesadillas while warm with toppings.  Unless you are throwing a party or extremely hungry, you’ll probably have a few leftovers here. That’s good! The quesadillas keep fine in the fridge for 4-5 days and reheat best in a 350˚F oven for 8-10 minutes until they are crispy and warmed through.  Did you love the recipe? Leave us stars below!
