What is a porterhouse steak?
A porterhouse steak cut is similar to a T-bone steak cut, as they both come from the same part of the cow: the loin. However, porterhouse steak has a larger section of tenderloin than T-bone steak. According to Certified Angus Beef® brand, the tenderloin in a Porterhouse steak is 1¼ inches or larger, while the tenderloin in a T-bone steak is between 1/2 to 1¼ inches around.
Essentially, a porterhouse steak cut is a choice cut of sirloin beef, and is tender and full of rich flavor, making it a favorite of grilled steak recipes!

How to Cook a Porterhouse Steak
Anyone who knows how to cook porterhouse steaks on the grill, knows it’s one of the most enjoyable ways to enjoy steak! Follow these instructions to make porterhouse steaks on the grill:
Grilling a Porterhouse:
- Preheat grill to medium-high.
- Season the steaks with salt and pepper and place on the grill.
Cook until desired doneness is reached, then remove from the grill and let rest for 4 minutes.
Grilling steak tips:
- You want your grill to be hot before you start cooking your steaks so they will sear beautifully and evenly.
- Look for a well-marbled cut of beef for the best flavor. You may wish to trim the excess fat, but make sure to leave some.

Making the Steak Dinner Sides:

- Add the potatoes, green beans, onion chunks, and mushrooms to the pouch.
- In a small bowl, combine the French onion soup and the garlic.
- Pour the liquid into the pouch, then add the butter on top.
- Seal the fourth edge and place on the grill to cook for about 10 minutes. Make sure you CAREFULLY remove the pouches from the grill, as they will be HOT!
- Serve the vegetables alongside the steaks.
