Directions
In a small bowl, whisk together the thyme, oregano, chili powder, cumin, and garlic powder. This is your flavor-packed spice rub.
Pat the flank steak dry with paper towels, then rub the spice mixture generously over all sides of the meat, pressing it in to adhere.
Season liberally with salt and pepper.
Let the steak rest at room temperature for at least 15-20 minutes to allow the spices to penetrate the meat.
Preheat your grill to a steady medium-high heat. Clean and lightly oil the grill grates to prevent sticking.
Place the seasoned steak directly on the hot grates.
Grill for 4-6 minutes per side for medium-rare, or until it reaches your desired level of doneness. Avoid pressing down on the steak to keep it juicy.
Transfer the steak to a cutting board and let it rest for 10 minutes. This is a crucial step that allows the juices to redistribute throughout the meat.
Using a sharp knife, thinly slice the steak against the grain for maximum tenderness.
Arrange the slices on a platter, top with the crumbled Monterrey Jack cheese, and serve immediately.
Don't be afraid to get a good char. High, direct heat is key to developing a flavorful crust on the outside while keeping the inside juicy and pink.
