About Sirloin
Top sirloin sits behind the loin, forward of the round. It’s lean, moderately tender, and has solid beefy flavor. It’s one of the most practical steaks in your share — works weeknights, holds up to marinades, and is forgiving for newer cooks.
Simple Cast Iron Method
Optional: marinate 30 minutes to 2 hours. Pat dry before cooking — wet meat won’t sear, it steams. High heat cast iron, 4–5 minutes per side. Rest 5 minutes. Slice against the grain at a slight diagonal for maximum tenderness.
