Flank Roast - Wagyu F1 x Angus

he Beef: This is 100% grass-fed F1 Wagyu, a first-cross of Full-blood Wagyu over Angus, raised for superior quality and grown with a deep respect for the land. The F1 cross is the sweet spot: it takes the Wagyu's fine intramuscular marbling and pairs it with the Angus frame and the deep, beefy flavour Australian cattle are known for. Flank is one of the beefiest-tasting cuts there is, and the Wagyu marbling gives it a tenderness it rarely has on leaner cattle.

The Cut: Flank comes from the belly of the animal, just behind the brisket and below the loin. It's a flat, long-grained muscle with very little waste and an intense, full beef flavour. Kept whole as a roast, it's one of the most versatile pieces on the animal: seared hard and sliced thin, it feeds a table quickly and looks the part on a board. The long grain is the key. Slice across it and every piece is tender.

How to Cook It: Take the flank out of the fridge 30–40 minutes before cooking and pat it dry. Season generously with salt and pepper, or give it a quick marinade.

Flank is best cooked hot and fast. Sear it on a screaming hot barbecue or in a heavy pan for 4–5 minutes per side, until well coloured. For a thicker piece, finish it in a 200°C oven for 5–10 minutes.

Grass-fed F1 Wagyu fat renders at a lower temperature than grain-fed, so it cooks a little faster and rewards a slightly gentler hand. Flank goes from perfect to chewy quickly once it passes medium, so keep a close eye on it.

Pull at 52–54°C internal for medium-rare and rest for 10 minutes. Slice thinly across the grain at a slight angle. This step matters more than anything else you do.

Tips

• Flank loves a marinade. Olive oil, garlic, lemon and herbs, or soy, honey and chilli. A few hours is plenty.
• Make it the centre of a share board with chimichurri, flatbreads and grilled vegetables.
• Slice it thin for tacos, steak sandwiches or a Thai beef salad.
• Look at the grain before you cook it, so you know which way to carve once it's resting.

A Little History: Flank was long a butcher's secret, cheap because it wasn't tender enough to fry like a sirloin. In France it's bavette's close neighbour on the bistro menu, cooked rare and served with shallots. In America it became London broil, marinated and grilled whole, then sliced thin across the grain. In Mexico, the same idea gave the world carne asada. Wherever it turns up, the lesson is the same: cook it quick, slice it right, and a humble cut eats like a prime one.
