Ingredients and Preparation
Before we begin, gather your ingredients and prep the beef. You'll need:
- 2 cups cooked, shredded beef (such as roast, stew meat, or taco filling)
- 4 large flour tortillas
- 2 cups shredded Mexican cheese blend or cheddar cheese
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 jalapeño, seeded and finely chopped (optional)
- 2 tbsp olive oil
- Salt and pepper, to taste
- Optional toppings: sliced avocado, fresh cilantro, sour cream, salsa, or guacamole
Cooking the Beef Mixture
In a large skillet, heat olive oil over medium heat. Add onion, garlic, and jalapeño (if using), cooking until softened, about 3-5 minutes. Stir in the shredded beef, breaking up any large pieces. Season with salt and pepper, and cook for an additional 5-7 minutes to combine the flavors. Remove from heat and set aside.

Assembling the Quesadillas
Preheat a large non-stick skillet or griddle over medium heat. Place a tortilla in the skillet, then sprinkle 1/2 cup of cheese evenly over one half of the tortilla. Top the cheese with 1/2 cup of the beef mixture, spreading it out in an even layer. Sprinkle another 1/2 cup of cheese over the beef. Fold the tortilla in half to cover the filling.
Cook the quesadilla for 2-3 minutes on each side, or until the tortilla is golden brown and crispy, and the cheese is fully melted. Transfer the quesadilla to a cutting board and repeat with remaining tortillas and filling.
Serving and Variations
Cut each quesadilla into wedges and serve with your favorite toppings. For a complete meal, pair your Leftover Beef Quesadillas with a side of black beans, corn on the cob, or a crisp salad.

To switch up the flavors, try these creative variations:
- BBQ Beef Quesadillas: Mix 2 tbsp of your favorite BBQ sauce into the beef mixture before assembling the quesadillas.
- Southwestern-Style Quesadillas: Add 1/2 cup of canned black beans and 1/2 cup of frozen corn to the beef mixture. Sprinkle with 1 tsp of cumin and 1/2 tsp of chili powder.
- Italian Beef Quesadillas: Replace the Mexican cheese blend with 2 cups of shredded mozzarella. Add 1/4 cup of chopped sun-dried tomatoes and 1 tbsp of chopped fresh basil to the beef mixture. Drizzle with balsamic glaze before serving.
With these Leftover Beef Quesadillas, you'll never look at leftovers the same way again. Enjoy your delicious and satisfying meal!
