Questions about Inside skirt steak

How do you cook inside skirt steak so it stays tender?

Pat it dry, then sear it in a smoking-hot pan or over a hot grill for about 2–3 minutes per side, depending on thickness. Rest it for 3 minutes, then slice thinly across the visible grain; cutting with the grain makes it chewier.

Should you marinate inside skirt steak?

A short marinade adds flavour, but it is not essential: the cut is already beefy and cooks quickly. If you use lime juice, vinegar or another acidic ingredient, marinate for 30 minutes to 2 hours, then pat the steak dry before searing.

How do you choose inside skirt steak at the butcher?

Look for a long, thin, visibly fibrous piece with an even thickness, and ask for the tough membrane to be removed if it is still attached. Inside skirt is often narrower and a little less fatty than outside skirt.

How long does raw inside skirt steak keep in the fridge?

Keep it covered on the lowest shelf and cook it within 3–5 days of purchase. To keep it longer, wrap it tightly and freeze it; thaw it in the fridge rather than on the worktop.

What dishes are made with inside skirt steak?

It is a classic choice for fajitas and steak tacos, and works well for carne asada. Sear it whole, rest it, then slice across the grain and serve with warm tortillas, salsa and sliced onion.

Can you use flank steak instead of inside skirt steak?

Yes. Flank steak is a leaner, slightly meatier substitute: it has 165 kcal and 8.29 g fat per 100 g, compared with 171 kcal and 9.8 g in inside skirt steak. Cook it hot and fast, then slice thinly across the grain.

What is inside skirt steak, and where does it come from?

It is a long, flat cut from the plate section of the cow, near the diaphragm. Its coarse grain and loose texture help it take up marinades, but make slicing across the grain especially important.

How can you tell when inside skirt steak is safely cooked?

For a whole steak, use a thermometer in the thickest part and cook it to 63 °C, then leave it to rest for at least 3 minutes. Colour alone is not a reliable way to judge doneness.
