Oyster blade steak is a tender, well-marbled steak cut from the beef shoulder blade, sold overseas as flat iron, and it is one of the best-value steaks in the butcher's case.
Most shoppers walk straight past it because of the line of sinew down the middle.
This guide explains what oyster blade is, where it comes from, why it costs so little and how to cook it fast or slow.
What Is Oyster Blade Steak?
Oyster blade steak is cut from the infraspinatus, a muscle that sits on top of the shoulder blade in the chuck, and it is named for its rounded, oyster-like shape. In the United States the same cut is sold as flat iron steak, and in the United Kingdom as feather blade or butler's steak.
Despite coming from a hard-working part of the animal, the muscle is genuinely tender, often rated second only to eye fillet. It carries good marbling, which gives it a rich, beefy flavour that punches well above its price.
The feature that defines the cut is the line of connective tissue, or sinew, running down its centre. It is the reason the steak is cheap and the reason it has a mixed reputation. Handled properly it is no problem at all, and in a slow braise it becomes an advantage.
In Australia oyster blade is usually sold as whole steaks with the sinew left in, and its spot on the shoulder is easiest to see on a chart of Australian beef cuts.
Is Oyster Blade Steak Good?
Yes, oyster blade is an excellent steak for the price: tender, well marbled and full of flavour, as long as you deal with the central sinew.
Cooked quickly with the sinew left in, that seam stays firm and chewy, which is where its tough reputation comes from. Trim it out first and the meat eats like a far more expensive steak. Leave it in and cook it low and slow, and the sinew melts into gelatine that enriches the sauce.
It suits cooks who like strong beef flavour and don't mind a little knife work. If you want a steak that needs no preparation at all, rump or porterhouse is the easier choice.
Why Is Oyster Blade Steak So Cheap?
Oyster blade is cheap because it comes from the chuck, a primal the market prices as budget stewing beef, and because the visible sinew puts many shoppers off.
Neither reason reflects how good the muscle actually is. You get marbling, flavour and real tenderness for far less than scotch fillet or eye fillet, which is why butchers and chefs have championed it for years.
That value puts it comfortably among the cheapest beef cuts that still eat well, and once you know how to handle the sinew, the hesitation at the counter works in your favour.
How to Cook Oyster Blade Steak
Oyster blade can be cooked fast as a trimmed steak or slow as a braise, and both work as long as you treat the central sinew correctly.
For a quick steak, trim out the sinew, pat the meat dry and season it well. Sear it in a very hot pan for 2 to 3 minutes a side for medium rare, pulling it at about 57C, then rest it for a few minutes and slice thinly across the grain.
For slow cooking, leave the sinew in and braise the whole steaks for two to three hours, until the connective tissue melts and the meat pulls apart. The same gentle approach used to slow cook beef in the oven works well here.
| Method | How to do it | Best for |
|---|---|---|
| Pan or grill | Trim the sinew, sear 2 to 3 minutes a side to medium rare, then rest | Quick steak dinners |
| Braise or slow cook | Leave the sinew in, cook low and slow for 2 to 3 hours | Stews, curries, pulled beef |
| Stir fry | Trim, slice thinly across the grain, cook fast over high heat | Asian-style dishes |
| Roast | Roast a whole piece at 160C for about 3 hours, to around 90C inside | Sunday roasts |
Oyster blade roast recipes
A whole oyster blade also roasts well, with the sinew melting into the meat over about three hours at 160C. Three ways to try it:
- A cranberry-stuffed oyster blade roast for a festive table
- An orange, honey and mustard glazed roast with a sweet, sharp crust
- A ginger, honey and soy oyster blade with an Asian-style glaze
Oyster Blade vs Flat Iron
Flat iron is oyster blade with the central sinew removed and split into two even steaks, so they are the same cut prepared two ways. If you buy flat iron, the trimming has been done for you.
Compared with other budget steaks, oyster blade is more tender than rump and far more tender than most chuck cuts, while costing much less than rib or loin steaks. When buying, look for even marbling and an even thickness, and decide first whether you will trim it for a fast steak or leave it whole for a braise.
Can You Buy Oyster Blade from Cost Cut Meats?
Not at the moment: oyster blade isn't in the Cost Cut Meats range, which focuses on whole grass-fed primals such as rump, striploin, scotch fillet and eye fillet.
If you like oyster blade for its beefy flavour and value, rump is the closest match in the range. A whole grass-fed rump breaks down into steaks, a roast and stir fry strips, and the current rump steak range starts from $26/kg in a 20kg box.
Rump is firmer than a trimmed oyster blade but needs no sinew work, and it cooks the same way: hot and fast for steaks, low and slow for larger pieces.
Conclusion
Oyster blade is the value steak savvy cooks keep quiet about: tender, well marbled and cheap, with a sinew that is easy to manage once you know how.
Trim it for a fast steak, braise it slowly for melting richness, or choose grass-fed rump when you want a value cut with no trimming at all.
