Tips for Perfect Quesadillas

Use the Right Cut of Steak

Flank steak or sirloin works best because they cook quickly and stay tender when sliced thin.

Don’t Overcook the Steak

Cook just until browned. Overcooking will make it tough.

Slice Against the Grain

This keeps the steak tender and easy to chew.

Use Medium Heat for Assembly

Too high heat will burn the tortilla before the cheese melts.

Press Lightly While Cooking

This helps everything stick together and melt evenly.
