Ingredients and Equipment
Before we start, gather your ingredients and equipment:
- Leftover steak (about 1 lb or 450g)
- 6 large flour tortillas
- 2 cups (200g) shredded Mexican cheese blend or cheddar cheese
- 1 small onion, thinly sliced
- 1 jalapeño, seeded and thinly sliced (optional, for heat)
- 2 tbsp (30ml) olive oil
- Salt and freshly ground black pepper, to taste
- Optional toppings: sour cream, guacamole, salsa, fresh cilantro, lime wedges
- Large non-stick skillet or griddle
- Spatula
- Sharp knife
- Cutting board
Preparation: Slice and Season the Steak
Start by slicing the leftover steak thinly against the grain. This technique shortens the muscle fibers, making the steak more tender and easier to chew. Season the sliced steak with salt and pepper, ensuring each piece is well coated.

Why Slice Against the Grain?
Slicing meat against the grain shortens the muscle fibers, making the steak more tender and easier to chew. This technique helps to break down the tougher connective tissues, resulting in a more enjoyable dining experience.
Cook the Steak and Vegetables
Heat the olive oil in a large non-stick skillet or griddle over medium-high heat. Add the sliced steak and cook for 2-3 minutes on each side, until heated through and slightly browned. Remove the steak from the skillet and set it aside.
In the same skillet, add the sliced onions and jalapeño (if using). Cook for 3-5 minutes, until the onions are translucent and softened. Stir occasionally to prevent burning.

Assemble the Quesadillas
Now it's time to assemble your steak quesadillas. Lay out the tortillas and sprinkle a generous amount of shredded cheese on one half of each tortilla. Top the cheese with an even layer of the sliced steak and cooked vegetables. Fold the tortillas in half to cover the filling.
Pro Tip: Don't Overstuff Your Quesadillas
It's tempting to pile on the filling, but overstuffing your quesadillas can make them difficult to flip and may cause the filling to spill out. Aim for an even layer of filling, and you'll have perfectly cooked, evenly melted quesadillas every time.
Cook the Quesadillas
With the skillet still over medium-high heat, place the folded quesadillas in the skillet. Cook for 2-3 minutes on each side, until the tortillas are golden brown and the cheese is melted and gooey. Use a spatula to carefully flip the quesadillas, ensuring they don't break apart.

Once cooked, transfer the quesadillas to a cutting board and let them rest for a minute or two before slicing. This allows the cheese to set and makes slicing easier.
Serve and Enjoy!
Slice each quesadilla into wedges and serve with your choice of toppings, such as sour cream, guacamole, salsa, fresh cilantro, and lime wedges. Enjoy your delicious steak quesadillas made from leftover steak!
