The T-bone steak is a fantastic cut because it contains some of the tenderloin and a NY strip steak in a single cut. The bone in the T-bone is also believed to add flavor and help lock in juices. It’s also a great steak for sharing between two people!
There are plenty of ways to cook a steak, but pan-searing/oven roasting is by far the best way to consistently cook a perfect steak every time. For my T-bone steak recipe, I use garlic, butter, and fresh rosemary-infused pan drippings to really enhance the flavor of the steak. The below method is what I like to refer to as the “steakhouse method,” utilizing high heat and real butter.
If you want to add more techniques to your skillset, I would love to teach you to reverse sear a steak, as well as how to achieve the perfect doneness with sous vide. Rubbing with coffee also brings great flavor to the table.

Porterhouse Steak Versus T-Bone
At a glance, the T-bone and porterhouse look like very similar cuts of beef. Both the strip and tenderloin are separated by the iconic T-bone running through the middle of the steak. The biggest difference lies in the tenderloin or filet mignon portion of the steak.
A true porterhouse has an entire sirloin and entire filet/tenderloin on either side of the bone, while the T-bone steak usually has a smaller sliver of the tenderloin. Of course, the porterhouse is much larger and is a more expensive cut of beef.
The Best Way to Cook T-Bone Steak
The secret to cooking the perfect T-bone steak (or any steak), is to combine pan searing with an oven finish. This gives you a slightly crusted outside with a juicy tender inside. The oven is better at providing indirect heat, while pan-searing gives you the much desired, grilled, and a slightly charred exterior.
Sear T-bone steaks for 2 minutes per side on the stovetop in a cast iron skillet on high heat with butter or oil, and then immediately transfer to a preheated oven at 415°F. Bake for 3-4 minutes for medium-rare. This recipe is ideal for steaks 1-1 1/2 inches thick. Steaks less than 1 inch thick should only be seared for 1 minute per side before transferring to the oven.
That’s the beauty of cooking with cast iron, you can easily transfer from stovetop to oven. If you don’t have a cast iron skillet, I highly recommend you get one. Cast iron gives you a “char-grilled finish” unlike stainless steel or nonstick pans. It’s like grilling indoors.
Temperature and Cook Times For Steak
Timing is everything when it comes to preparing steak. I use my phone to precisely clock each step as written in the chart below. If you really adhere to cooking times I promise you will never overcook a steak again.
Always shoot for a temperature a little cooler than your final desired serving temp. Beef will continue to cook during the rest period after it’s taken off the heat. A digital thermometer is a worthwhile investment.
| Doneness | Temperature Range | Oven Duration |
|---|---|---|
| Very Rare/rare | 120° F to 125° F | 4 minutes |
| Medium rare | 125° F to 130° F | 4-5 minutes |
| Medium | 135° F to 140° F | 6-7 minutes |
| Medium well | 145° F to 150° F | 7-8 minutes |
| Well done | 160° F and above | 10+ minutes |
Note: Cooking steaks at high temps in a skillet tends to get smokey. Open a kitchen window and turn on your kitchen’s overhead vent fan before you start to help with ventilation.
Let Steaks Rest
The legend, Anthony Bourdain once said, the most important aspect of cooking any steak is the rest period after you take it off the heat. Letting a steak rest for 5-7 minutes before cutting is critical for two reasons. One, it continues to actually cook the steak. Second, the juices evenly distribute throughout the meat, yielding the perfect bite every time.
I like to finish my steak by spooning the garlic and herb-infused pan drippings over the steak before serving. This will deliver so much fantastic flavor in every bite.
What to Serve With Steak
You can never go wrong with steak and potatoes. Pair this porterhouse steak with my parmesan roasted fingerling potatoes or my garlic butter roasted red potatoes. If you’re looking for ultra-crispy potatoes, try my pesto smashed potatoes! If you prefer mashed potatoes, try my rich and delicious cream cheese mashed potatoes.
My favorite veggie of choice will always be my roasted bacon and parmesan Brussels sprouts. Make this recipe surf and turf with pan-seared lemon butter scallops or baked lobster tails.

T-Bone Steak with Garlic and Rosemary
Ingredients
- 1 T-bone steak, roughly 1-1 1/2 inches thick
- 1-2 sprigs of fresh rosemary
- 1-2 sprigs of fresh thyme
- 2 tablespoons butter
- 1-2 whole garlic cloves
- salt and pepper to taste
Instructions
- Preheat the oven to 415° F. Remove steak from the fridge 30 minutes before cooking, this is to bring the steak to room temperature and ensure your cooking times are more accurate. Season both sides liberally with salt and pepper.
- Add butter to an oven-safe cast iron skillet and turn up high, allowing the skillet to become hot. Place the T-bone steak face down and sear undisturbed for 2 minutes. Flip and sear for an additional 2 minutes. This will give your steak a nice seared exterior.
- Add whole garlic cloves, fresh rosemary, and thyme to the skillet and immediately transfer your skillet directly to the oven [WARNING] skillet may be hot, handle with oven mitts. For rare, bake for 4 minutes. Medium-rare, 4-5 minutes. Medium, 6-7 minutes. Medium-well, 7-8 minutes. Remember, depending on the thickness of the steak, the more or less time it will take. This recipe is ideal for 1-1 1/2 inch thick portions (about 16-24 ounces). Steaks less than 1 inch thick should only be seared for 1 minute per side before baking.
- Remove the steaks from the oven and spoon the garlic and rosemary-infused butter drippings from the pan over the steaks. Plate the steak and let sit for 5 minutes before serving. This is important to bring your steak to its final serving temperature.

This ruined my steak . My butter burned, burned the steak. I’m sad.
That’s a bummer. The outer edges should certainly sear up but I’m surprised it burned. Did you stick to 2 minutes per side in the skillet and then finish in the oven? What did you do for cook times?
Wow, this was our first time cooking steaks in a cast iron and it was the best steak my boyfriend and I have ever had. We cooked 2 very large T-bone steaks from Costco, about 3.5 lbs total. We followed the directions to a T but decided to sear the steaks separately due to their size and cooked them in the oven for about 9 minutes total. They came out perfectly medium-rare, juicy, and delicious. The rosemary garlic sauce was something else. Before cooking the steaks we both said we weren’t very hungry and probably wouldn’t eat most of each steak, but lo and behold they were so delicious we finished every last bite. No regrets!
Thanks Shelley. I’m pumped for your new discovery of steaks in cast iron. It’s life changing…really. BTW, those monster steaks sound phenomenal.
This was delicious and very tender!! YUM!
Awesome! Can’t believe it took me so long to try this method! Thank you so much for the great recipe. Just like a restaurant and super easy. Much better than grilling.
That’s great – I’m really glad you found me then!
Tried this recipe using a cuisinart grill and it was great! I was afraid to use my old cast iron pan on ceramic stovetop. Will do this the next time we have company over for dinner
Yes that’s the only downside. Need to be careful to not slide the skillet on the glass.
Beautiful recipe, made it for the family and they loved it! Thank you, Shawn!
You’re welcome, Aut! Thanks for dropping a note.
Made this & it was super! Thanks Shawn
You’re very welcome, Tyhesha
Don’t have a cast iron skillet only stainless steel….does this mean I can’t make this recipe? ?
Hi Jan – if your stainless steel has no rubber on it and it’s oven safe, then you can still make the recipe. But a brief disclaimer, I’ve never tried this recipe with stainless so I can’t guarantee you’ll get the same results. You should pick up a cast iron skillet for next time. I think you’ll find you will put it to great use!
Thank you for a really great recipe! I went out and purchased a cast iron skillet just to try it. The pan searing was perfect and the timing guide you provided for the oven was spot on. I followed your instructions to the T and my steak was the best I’ve ever prepared at home. I’m usually afraid that I’ll over season my food so I appreciate your suggestion on being liberal with the salt and pepper. Thanks again!
Music to my ears Sherrie. Glad you got yourself a cast iron skillet. I think you’ll find you can put it to good use – esp on this blog if I might add 😉
Wow! Just tried this recipe. As a new homeowner, a grill was not at the top of the expense list. But, thanks to you, my skillet can now cook an amazing steak. It was so juicy, tender, and perfectly seasoned. My sirloin was a little well-done, but the filet ended up juicy and soft. Thank you so much for posting this simple, yet delightful, recipe!

Thanks Justin, it’s amazing how good of a job cast iron can do. I can tell you it’s been a while since I’ve grilled steaks. Thanks for note.
