Ingredients
Method
- Toss the flank steak strips with the chili powder, garlic powder, smoked paprika, cumin, salt, and black pepper. Heat the olive oil in a large skillet over medium-high heat and cook the steak in a single layer for 3 to 4 minutes, flipping once, until the edges are browned. Transfer to a plate.
- Stir together the mayonnaise, pickled jalapeños, jalapeño brine, garlic powder, smoked paprika, cumin, and cayenne in a small bowl until smooth.
- Spread 2 tbsp of jalapeño sauce over one half of each tortilla. Top with one-quarter of the steak and 1/2 cup shredded cheese, then fold the tortilla closed.
- Melt a portion of the butter in the wiped-out skillet over medium heat. Cook each quesadilla for 2 to 3 minutes per side, pressing with a spatula, until deep golden and crisp. Repeat for all 4 quesadillas.
- Slice each quesadilla into 3 triangles and arrange on a plate. Drizzle with any remaining jalapeño sauce or serve it alongside as a dip.
Notes
The jalapeño sauce tastes even better made the day before, so if you have a minute in the morning, mix it then and refrigerate it. Make sure your pan is fully hot before the steak goes in; a lukewarm pan stews the meat instead of browning it. Leftovers reheat well in a dry skillet over medium-low heat.
