Perfectly Grilled T-Bone Steak Recipe (2024)

When it comes to steak, I'm aneconomy cuts man. Well, I say with a bit of a grumble that I was an economy man before my choice cuts ofskirt,hanger, andflankbecame so desirable that their market value shot up beyond "bargain" territory. Still, they're easier on the wallet thanhigh-end cutslike ribeyes and T-bones, which I certainly love but can hardly justify buying, knowing that I'll be just as happy with a steak that's a quarter of the cost.

But I'm also a man who would never pass up a porterhouse under the right circ*mstances, so whenKenjiasked me to develop a recipe for perfectly cooked T-bone steaks (courtesy ofPat LaFrieda meat), I jumped at the opportunity. The well-marbled,dry-agedprime steaks delivered to SE headquarters were so beautiful that I affectionately dubbed them "my babies," and promised myself that no harm would come to them.

I've grilled enough steaks to know how to treat them right, but I did pit a few winning T-bone techniques against each other to see if one would ultimately earn me the title of #1 Steak Dad.

Anatomy of a T-Bone

The T-bone is a twofer: You get both the strip loin and the tenderloin in one cut. The bone portion of the T-bone is part of the steer's vertebrae, from the short loin primal (that's the spot between your rib cuts and your sirloin cuts). If you rotate the "T" of the T-bone to be situated horizontally, with the bigger portion of meat on top, you can better see where this cut lies on the cow.

The strip loin—also called a New York strip steak—is the larger portion of the T-bone. The chunk of meat sits on top of the vertebrae—the back of the steer. On the other side of the bone is the tenderloin, which sits next to the lower part of the spinal cord. A single T-bone is only one half of this spinal section. Yeah. Cows are big.

Although it's not a hard and fast rule, to be considered a T-bone, the tenderloin section generally needs to be at least a half-inch wide from the edge of the bone to the edge of the meat. When the tenderloin section jumps up to one and a half inches wide or more, it can then gain the title of "porterhouse," althoughtechnically, you can still correctly refer to it as a T-bone. The porterhouse comes from the back of the short loin, where the tenderloin section is larger.

T-Bone Selection and Prep

To get the perfect T-bone for grilling, there are a few important things you'll want to look for:

Thickness

First and foremost, you want to go thick with your cut. A minimum height of one and a half inches is best; two inches is even better. When grilling a steak, you want to be able to develop that dark, crusty sear while keeping the inside a nice rare to medium-rare. That's a near-impossible feat with a thin steak, since the inside will be thoroughly overcooked by the time the outside develops a proper sear. A hefty cut that's big enough to split between two or more is key to achieving a perfectly cooked T-bone.

Marbling

Next, you want to check out the marbling. Marbling is made up of intramuscular fat, and you're certain to see more of it in the strip loin than in the tenderloin, but both should have streaks of beautiful white fat in them. This fat is what brings the big, beefy flavor to the T-bone, and you won't get that top steakhouse flavor without it. You should always do a visual inspection to best determine the marbling, but in terms of USDA beef grades, "Prime" is the label to look for. "Choice" is the next step down in marbling, followed by "Select."

Size of the Tenderloin

Finally, if you want that tenderloin section to be all it can be, it's best to choose a T-bone with a generous portion of tenderloin. Fat doesn't just deliver flavor—it also insulates. Because the tenderloin is leaner, it'll always cook through more quickly than the strip; the smaller it is, the faster it will do so. To ensure the filet section of the T-bone comes out to a respectable medium-rare, porterhouse-sized tenderloin sections of one and a half inches or larger are definitely the way to go.

Once you have your perfect T-bone, prep doesn't need to go any further than salt and pepper. Salting should be done at least 40 minutes prior to grilling, with a heavy layer of kosher salt—remember that you're seasoning for a thick, meaty steak. Kenji has already explained all thescience behind salting, but basically, the salt needs time to first draw moisture out of the steak, and then break down the muscle fibers, so that the now-concentrated, flavorful liquid that was drawn out can be reabsorbed.

Right before the steak is ready to hit the grill, it can be given a layer of freshly ground pepper, to taste—I personally like a lot of coarse pepper, which gives the crust of the final steak a sharp bite and a little extra crunchy texture.

Some folks prefer adding pepper at the end, claiming that it can taste burnt or bitter if added before cooking, but Ilikethe flavor of charred pepper. It does have a bit of bitterness, but it also attains a sweetness that balances it out.

Grilling a T-Bone: 3 Methods, 1 Winner

As I mentioned, I had no intention of destroying any of these beautiful porterhouses I had in my possession in the name of experimentation. So when it came time to grill them, I stuck to the methods that I knew would lead to success. While no steaks were harmed in the making of this post, there was certainly one that was better than the rest.

Method 1: The Sear and Roast

If you take a stroll back in time, you'll find me proclaiming that the best way to cook a massive T-bone is to sear it over high, direct heat, then move it to indirect heat to finish cooking. This is certainly the method you'll most commonly come across, and it's served me well with many a steak. So, even though I do things a little differently now, I thought it was only right to give the sear-and-roast method a fair shot.

To develop a great sear on an uncooked steak, you want to go for the highest heat you can get. With charcoal, this is the point when a whole chimney full of coals has just finished lighting and is covered in gray ash. When I dumped my fresh batch of briquettes out, my thermometer tipped off the scale, but I was likely running around 650°F (343°C)—lump charcoal will get you a good 50°F-plus higher.

Over this heat, the steak seared beautifully, especially since I flipped it every 30 seconds or so to cook it evenly and maximize that crust. Once it was browned to my liking, I transferred the porterhouse to the cool side of the grill and positioned it so the strip loin was facing the fire. Then I covered the grill and let the steak cook until it reached my desired temperature of 125°F (52°C), for a medium-rare tenderloin.

After giving it a 10-minute rest, I sliced into both the strip loin and the tenderloin and was pretty pleased—both had a rosy-red, soft center, with not too much grayness around the edges. It was a worthy steak, but I've come to learn that it can be even better.

Method 2: The Reverse Sear, Version 1

For more of an even, edge-to-edge cook in a large steak like this, the reverse sear is your best friend. It's a method that Kenji developed forCook's Illustrateda while back.

As the name implies, this method swaps the roasting and searing, so the steak is first brought up over indirect heat to a temperature about 5°F below your final desired doneness, then seared over direct heat. This usually results in a steak that's more evenly red throughout. It's also a more effective way to sear, since the steak's exterior will have less moisture to burn away after it's been cooking for a bit. With a porterhouse, though, I questioned what the best roasting position would be in order to achieve perfect doneness in both the strip loinandthe tenderloin.

The first theory I tested was that the steak should be situated so the tops of both the strip loin and the tenderloin faced the fire. Since the tops of both sections of the T-bone are larger than the tapered bottom, it would make some sense that the top should take longer than the bottom to cook.

As I kept an eye on the temperature of each side of the T-bone, I quickly learned I was wrong. Since the tenderloin has less fat than the strip, it actually cooked faster, registering a good 5°F hotter than the strip all through the cooking process. This wasn't going to work out—if anything, given its relatively low-fat content, the tenderloin needs to belesscooked than the strip.

In terms of even cooking, it was a decided improvement over the first steak, with a more even rosy color throughout. But we can do better.

Method 3: The Reverse Sear, Version 2

With the last of my three porterhouses, I went with the reverse sear again, but this time positioned the strip to run parallel to the fire, with the tenderloin facing away from the coals. As I monitored the temperature this time, the tenderloin was coming in at least 5°F cooler than the strip, which was exactly what I wanted to see.

After letting the steak roast until the strip hit 115°F (46°C) and the tenderloin was at 110°F (43°C), I quickly seared it off, let it rest, and cut in.

This time around, the strip was perfectly medium-rare from edge to edge. The more delicate tenderloin still had a little grayness around the sides, but to a lesser extent than in my previous attempts, making this method the clear winner.

T-Bone Enhancement

All of those steaks were beefy, salty, peppery, and just all-around delicious. But they were still missing a component of pan-searing steaks that's lost on the grill—butter basting. When cooking indoors with a cast iron skillet, I add some butter and herbs to the pan, basting the seared steak with the rich, melted fat as it cooks.

To bring a little of this butter-herb infusion to my grilled steak, I melted a few tablespoons of butter in a small saucepan, then added thyme, garlic, and lemon zest and let those "steep" together as the hot butter cooled. Once that last porterhouse came off the grill, I spread a decent portion of that flavorful butter over the steak while it was resting.

I had a few other tasters with me to help eat through all these steaks, and, while each successive T-bone was well praised, it was the one with the butter that really stood out and had me feeling like I had rightfully raised the steaks and earned that title of #1 Steak Dad. (Is it strange that I'm the kind of dad who eats his perfectly charred, rosy-red babies?) Now, if only these babies were able to get me a mug stating my achievements, so I could properly show them off to the world...
