FAQs
Can I use a different cut of steak?
Yes, skirt steak, sirloin, or ribeye can also work well. Just adjust cooking times if needed since thickness and tenderness vary.
How do I know when the steak is cooked properly?
The steak should be cooked through but still tender, usually about 10 minutes in the oven at 400º F for thinly sliced flank steak. Letting it rest before serving helps retain juices.
