FAQ
How do I keep skirt steak from turning chewy?
Two rules: do not overcook it, and slice it against the grain. Skirt steak has long muscle fibers, so cutting across them shortens the bite and makes it tender.
What internal temp should I aim for?
Skirt steak shines at medium-rare to medium. Here is a helpful range (pull a few degrees early because of carryover heat):
- Rare: 120 to 125°F
- Medium-rare: 130 to 135°F
- Medium: 135 to 145°F
Resting will bump the temp up slightly, which is why I like pulling medium-rare around 128 to 132°F.
Can I cook this without an outdoor grill?
Yes. Use a cast iron skillet or a grill pan over high heat. You want serious heat and good ventilation. Open a window and commit.
How long should I marinate skirt steak?
Minimum 20 minutes, ideal 45 to 60 minutes. Because the marinade has acid (lime), I do not recommend going beyond 4 hours or the texture can get a little weird.
Is flank steak the same thing?
Not exactly. Flank is thicker and a bit leaner. You can swap it in, but give it a little longer cook time and keep the same rule: slice against the grain.
How do I know it is done without a thermometer?
Look for a deep brown crust and an interior that feels springy but not hard when you press the thickest part with your finger or tongs. Medium-rare will look warm red in the center when you slice into a test piece. If you are unsure, a thermometer is still the easiest way to nail it.
What should I serve with it?
Rice, grilled corn, a big salad, roasted potatoes, or warm tortillas. Also: crispy smashed potatoes plus chimichurri is a life upgrade.
