Chef Steve Tips for Making This Recipe

Pro Tips from Chef Steve

Against the Grain: Always slice flank steak across the grain for maximum tenderness.

Room Temp = Juicier Meat: Letting the steak sit before grilling helps it cook more evenly.

No Grill? No Problem: Use a cast iron skillet or grill pan on high heat indoors.

Double the Marinade: Make extra to drizzle over the cooked steak (just boil it first for safety).

FAQs

1- Can I use another cut instead of flank steak?

Yes! Skirt steak or flat iron are great substitutes that work beautifully with this marinade.

2- How long can I marinate flank steak?

For best results, marinate for 8 – 24 hours. Don’t go beyond 36 hours or the texture can get mushy.

3- What’s the best way to tenderize flank steak?

An acid-based marinade like this one is the best method. Always slice against the grain after cooking for even more tenderness.

4- Can I freeze the marinated steak?

Absolutely! Add steak and marinade to a freezer bag and freeze for up to 2 months. Thaw in the fridge overnight before grilling.

5- How do I know when it’s done?

Use a meat thermometer. Medium-rare is 130 – 135°F. Let it rest 5 – 10 minutes before slicing to keep the juices in.
