The Perfect Porterhouse Steak & Marinade

READY IN: 25mins
Recipe by dmcpherr

This recipe comes from my Dad's recipe file. It's a real treat to visit and have Dad make his trademarked, perfectly grilled and seasoned porterhouse steaks! The marinade is so simple that I'm able to do it in 5 minutes before heading off to work in the morning. Enjoy!

I used this marinade on some T-bones. I added some coarse ground black pepper and used shallots instead of onion. The steaks were delicious, juicy, and tender. I brought them to room temperature before grilling and let them rest for a few minutes before serving. They certainly did not have the texture of "Rubbermaid". I actually tried your marinade before posting a review and I am glad I did. This would make a great marinade for less expensive cuts of beef. Let's face it, top cuts are not always in everyone's budget. Thanks for sharing your Dad's recipe with us!
