Why is a porterhouse steak so popular and sought after? Like a T-bone steak, the porterhouse has two distinct portions separated by the “T” shaped bone: the larger beefy New York strip steak and the smaller, more tender filet mignon. However, to qualify as the hefty porterhouse steak, the filet portion has to be at least 1.25 inches thick, measured from the bone to the widest part of the filet. The strip steak side provides a bold, beefy flavor while the filet mignon side adds a more mild and tender meat flavor. Add the distinctive taste of the fatty bone, and you have a three-punch combination of juicy, mouthwatering, heavenly meat deliciousness that is unparalleled in the steak universe.

Directions For Grilling Porterhouse Steak With Thyme-Butter And Lemon

1. Set up your Weber Kettle for direct grilling – Fill your charcoal chimney fire starter with charcoal briquettes, and when ready, empty the chimney in the center of the charcoal grate and, with tongs, spread them around to form a neat pile.

2. Bring the porterhouse steak to room temperature – Let the porterhouse steak rest on a plate for 15 minutes. Then, wipe off the moisture and liberally apply the salt and pepper to both sides.

3. Place the porterhouse steak on the Weber Kettle grill grate – Place the porterhouse steak in the grill grate directly over the coals and grill for 5 minutes, then flip it over and grill for another five minutes, depending on the thickness of your porterhouse steak. Check the internal temperature of the porterhouse steak in the thickest part with a meat thermometer. You’re looking for a temperature of 130 degrees for medium rare. Also, when you flip the steak, place the four lemon halves on the grill cut side down in order to char the lemon.

Variations And Substitutions For Weber Kettle Grilled Porterhouse Steak With Thyme-Butter And Lemon

Try other cuts of steak – Of course, we are singing the praises of the porterhouse steak here, but any large cut of steak like a rib eye, tomahawk chop, thick New York strip, London broil, or tri-tip will go very well with the thyme-butter and lemon.

Use other fresh herbs – The fresh thyme, butter, and grilled lemon is an extraordinary combination of flavors that enhances the beefy goodness of the porterhouse steak. But you can also substitute the thyme with other fresh herbs like dill, rosemary, sage, basil, oregano, and parsley.

Add soaked wood chips – If you want to add a bit of smokey flavor to your porterhouse steak, add some small wood chunks or wood chips soaked in water to the top of your charcoal pile. The smoke from the soaked wood will add just a hint of smokey goodness to your porterhouse steak.

Tips And Tricks For Weber Kettle Grilled Porterhouse Steak With Thyme-Butter And Lemon

What’s the best way to tell when your porterhouse steak is done – Check the temperature with a meat thermometer. The thermometer should slide into the meat very easily. Use a meat temperature chart to gauge the doneness. Alternatively, with a bit of practice, you can become a very good judge of doneness using the American Heart Association “steak doneness test” and learn to “push” on your steak.

Should I remove the bone and carve the meat, or leave the meat on the bone – Most high-end steak houses carve the New York strip and the filet off the bone, carve the meat into smaller portions, and serve it to their customers. That’s just fine at a high-end steakhouse. But at home, I prefer to leave the bone attached to the steak, place it on a large plate and serve it. It creates a larger-than-life presentation, and it portends generosity. Let your guests carve the meat off the bone themselves, then feast on the bone afterward.

Grilling the lemon – If you have not done this before, it’s quite a delicious trick. Placing the lemon cut side down on the grill helps loosen up and warm the lemon’s juice. And it adds a bit of smokey lemony deliciousness to your porterhouse steak. Plus, it looks so darn cool, too, as a delightful garnish!
