What cut of steak is best for carne asada fries?
Flank or skirt steak are ideal—they're thin, tender, and absorb the citrus-garlic marinade quickly, cooking in minutes over high heat.
How long should I marinate the steak?
At least 30 minutes for basic flavor, but 2–4 hours is better for deeper marination. Don't exceed 8 hours or the citrus juice will over-tenderize the meat.
Can I make carne asada fries without a grill?
Yes. Use a cast-iron skillet or griddle over high heat. Sear the steak 2–3 minutes per side until charred and cooked to your preference.
Should I make the fries from scratch or use frozen?
This recipe calls for frozen fries for convenience. Bake or fry per package directions until golden and crispy, then assemble immediately before cheese melts.
Can I prep these ahead?
Marinate the steak up to 8 hours. Cook fries fresh before serving. Grill steak just before plating so it stays warm and the cheese melts properly.
