Why This Recipe Works

This brings out the natural sweetness in the onions and adds depth to the dish. We'll also use a combination of cheese, including cheddar and Monterey Jack, to give the quesadillas a rich and creamy flavor.

How to Make Beef And Onion Quesadillas

1
Heat the olive oil in a large skillet over medium-high heat. Add the diced onion and cook until it is translucent and starting to caramelize, about 5-7 minutes.
2
Add the minced garlic to the skillet and cook for an additional 1-2 minutes, until fragrant.

Add the ground beef to the skillet, breaking it up with a spoon as it cooks. Cook until the beef is browned, about 5-7 minutes.

5
In a large bowl, combine the cooked beef mixture, shredded cheddar cheese, and shredded Monterey Jack cheese. Stir to combine.
6
Heat a large skillet or griddle over medium heat. Place a tortilla in the skillet and sprinkle a quarter of the beef and cheese mixture onto half of the tortilla.
7
Fold the tortilla in half to enclose the filling. Cook for 2-3 minutes, until the tortilla is crispy and the cheese is melted.
8
Flip the quesadilla and cook for an additional 2-3 minutes, until the other side is also crispy and the cheese is melted.
