What is a Porterhouse Steak?
Porterhouse steak is a bone-in steak made up of filet mignon steak and New York strip steak. It's two of the most tender steaks in one, and as a result is a large, juicy steak with plenty of flavor. Porterhouse is often served as a steak for two.

How to Cook a Porterhouse Steak
- Generously season room-temperature porterhouse steak on both sides.
- Sear for 5 minutes on each side over high heat directly on the grill. Allow it to rest for 10 minutes before slicing.
- Combine your chimichurri ingredients in a bowl, then serve over top sliced steak. Follow our step-by-step guide to making the best chimichurri for steak.
Best Way to Cook Porterhouse Steak
- My 1.25-pound steaks cook on the grill until they’re medium rare, following this recipe. This is an internal temperature of 130 degrees Fahrenheit. Add 5 degrees for medium-well steak, 10 degrees, for well-done, and subtract 5 degrees for rare.
- If you want to make some gorgeous diamond grill marks, turn the steak 45 degrees halfway through each side’s grill time as we do in our Grilled New York Strip Steak recipe.
- If you don’t want a spicy chimichurri sauce, you can leave out the crushed red pepper.
- If you have a smaller or bigger steak, don’t focus on the time cooked, but on the internal temperature. Use a meat thermometer for best results.

Porterhouse Steak Recipes FAQs
Porterhouse is a larger version of the t-bone steak with more tenderloin beef. T-bone steaks have a smaller amount of tenderloin attached to the bone, meaning the difference between a t-bone steak and a porterhouse steak is purely the size of the steak.
You do not need to marinate porterhouse steak for great flavor. Grilled porterhouse steak is tender and juicy without a marinade.
Let porterhouse steak come to room temperature before grilling. Then, generously season the front and back of the steak and sear for 5 minutes on each side over high heat directly on the grill. Always let the steak rest for at least 10 minutes after grilling before slicing.
Porterhouse steak should cook on the grill until reaching an internal temperature of at least 130 degrees Fahrenheit. See my Steak Temperature Chart for more information. Use a meat thermometer to check the temperature of your steak. I cook my 1.25 pound porterhouse steaks for 5 minutes on each side. If your steaks are larger, they will need more time on the grill.
Chimichurri sauce is a mix of fresh parsley, fresh oregano, olive oil, salt, pepper, white wine vinegar, minced garlic, and crushed red pepper.
Chimichurri sauce has a bright, herbaceous flavor with a hint of spice from red pepper flakes. It adds so much flavor to a steak without overpowering the beef.
