Why a Leftover Steak Quesadilla?

Ingredients and Equipment
Here's what you'll need to create this delightful dish:

- Leftover steak (about 1 cup, sliced)
- 2 large flour tortillas
- 1 cup shredded cheese (Mexican blend or cheddar)
- 1 small onion, thinly sliced
- 1 jalapeño, seeded and thinly sliced (optional)
- 1 tbsp olive oil
- Salt and pepper, to taste
- Optional toppings: salsa, guacamole, sour cream, fresh cilantro
You'll also need a large non-stick skillet or griddle, a spatula, and a sharp knife for slicing.
Preparation Steps
Step 1: Prepare Your Ingredients
If you haven't already, slice your leftover steak into thin strips. This will help it heat evenly and distribute the flavor throughout the quesadilla. Set it aside. If you're using a jalapeño, prepare it now. Thinly slice the onion and have your cheese and tortillas at the ready.
Step 2: Cook the Steak and Onions
Heat the olive oil in your skillet over medium heat. Add the sliced onions and cook until they soften and begin to caramelize, about 5-7 minutes. If you're using jalapeño, add it now and cook for another minute.

Add the sliced steak to the skillet. Cook for 2-3 minutes, stirring occasionally, until the steak is heated through and has absorbed some of the flavors from the onions. Season with salt and pepper, then remove from heat and set aside.
Step 3: Assemble the Quesadilla
Lay one tortilla flat on a clean, dry surface. Evenly sprinkle half of the shredded cheese over the tortilla, leaving a small border around the edge. Distribute the steak and onion mixture evenly over the cheese. Sprinkle the remaining cheese over the steak, then top with the second tortilla.
Step 4: Cook the Quesadilla
Heat the same skillet over medium heat. Carefully place the assembled quesadilla in the skillet. Cook until the bottom tortilla is golden brown and crispy, about 2-3 minutes. Carefully flip the quesadilla and cook the other side for another 2-3 minutes, or until the cheese is fully melted and the tortilla is crispy.

Step 5: Serve
Transfer the quesadilla to a cutting board. Let it cool for a minute, then slice it into wedges. Serve immediately with your choice of toppings. Enjoy your Leftover Steak Quesadilla!
