Holding a hunk of high-end Wagyu beef in your hand makes you feel a certain type of way: panic. You’ve got something very special in front of you, yet you don’t know how to cook it without making a total mess. Your reflexive urge is probably to do what you’d normally do with a steak: throw it on a hot pan, sear the hell out of it, then cook it until it’s done.
But you’re missing the whole picture. Wagyu isn’t just beef, it’s a feat of engineering, an anatomical miracle of marbling, and it require you to think about it differently. To avoid an expensive mistake, you must understand where every cut comes from and how that part of the animal reacts to heat; this is the difference between a good meal and a great one.
How to Cook Wagyu Beef
The image above lays out the body of the beast, breaking down the animal into each cut (from tenderloin to brisket) and helping you get a sense for why some cuts excel on the grill while others prefers to soak slowly in a pot of simmering broth. But while the Japanese grading system may appear confusing upon first glance, it really boils down to two things: yield and marbling. So when you read an A5, what you’re seeing is pretty much the top shelf of intramuscular fat. Those so-called BMS scores that push into the double-digits.
Not that this has anything to do with luxury, actualy. It’s about texture. Because the fat in Wagyu melts well below the temperature of regular beef, it will render out fast, coating your tongue instead of accumulating in your stomach like a layer of heavy oil. This brings us back to why the chart emphasizes particular preparation techniques for certain cuts. You wouldn’t slow-braise a tenderloin, or throw a brisket up on the grill and expect anything but tough meat if it was grilled too thin over too high a flame.
Seeing these relationships shown on the chart also helps illustrate what muscles are worked hard versus what remains shielded from such activity. For example, consider the Karubi, also known as short ribs. These come from the rib section and sit close to both fat and bone layers. In other words, they pack a lot of flavor. These days, when prepared at home, they’re usually grilled Yakiniku-style. This means you cook bite-sized chunks yourself on a grill at the dining table, right on top of the open fire.
On the other hand, consider the Hire, or tenderloin. This part of the cow is so delicate, it’s commonly eaten either raw or rare in expensive restaurants. Looking at them side by side shows that not all Wagyu has the same texture. Some parts are meant to melt away almost immediately, while others are meant to be chewed slowly as you enjoy the mix of muscle and fat. Being aware of this difference prevents you from under-seasoning the robust flank, or overcooking the delicate loin.
For example, there’s one mistake that many home cook fall into: thinking that they can cook every type of Wagyu the exact same way. For instance, if you get a cut of meat from an A1, which means it has very little marbling, it is going to act quite similarly to quality American beef. It should of been cooked for longer periods and possibly with additional fat. On the other hand, an A5 will take care of itself. With so much natural umami, you don’t need any seasonings and certainly not any butter.
The graphic makes this scale pretty clear; as you increase the grade, so does the amount of fat. And that makes all the difference in cooking. If you’re working with a leaner, thicker cut, you’ll want to sear it different than an A5. Be mindful about the timing and use lighter heat.
Once at the stove, the rule is simple: season it lightly with a bit of salt, warm it in your hand, cook it on medium heat, and never add any kind of oil. And again: Don’t crowd the pan. Rare to medium-rare internal temperature are the goal since the fat will melt fast. Pushing it beyond this will result in an unpleasant waxy texture. And don’t forget resting, though only briefly is fine. Cut thinly if it’s tough, thicker if it’s as tender as the striploin.
You want to avoid interfering with the taste; no need for heavy marinades here, nor too much charring either. So in the end, when it comes to preparing Wagyu, it’s all about moderation. This is an ingredient that has been fed and bred for hundreds of days to reach a certain level of tenderness and marbling. Take a step back and let the beef speak for itself. Respect the process.
Whether you’re searing a tenderloin or throwing some short ribs on the grill, trust that the quality of this meat will do most of the work. Consult the chart, make a few adjustments based off your heat source, and let the taste do the talking. When it comes to Wagyu, the easiest way to have a good experience is to not think too hard, just savor the richness and buttery finish on your tongue.
