Why This Recipe Works

The balsamic marinade transforms flank steak from tough to tender, while honey’s natural pectin caramatizes perfectly. Rosemary acts as the star herb, adding earthy depth without overpowering the meat’s richness.

Cooked to medium-rare, this steak balances bold flavors with a tender, juicy core. Leftover slices work equally well in salads or sandwiches the next day.

FAQS

Can I cook this in the oven?

Yes, sear first then finish at 400°F for 12-15 minutes if cooking in oven for thicker cuts.

How to test doneness?

Use instant-read thermometer – 125°F for rare, 130-135°F for medium-rare, 140°F for medium.

Why is my steak tough?

Overcooking above medium doneness or not slicing against the grain makes flank steak chewy.

Can I prepare ahead?

Marinate up to 24 hours in fridge. Bring to room temperature before cooking.

Best wine pairing?

Full-bodied Cabernet Sauvignon complements the steak’s richness and balsamic complexity.
