Beef

Marinade

Side Dish

Method

Prepare the Marinade

  1. 1

    Make the Marinade

    In a small bowl, whisk together olive oil, minced garlic, fresh rosemary, salt, and black pepper until well combined.

  2. 2

    Marinate the Steak

    Place the porterhouse steak in a large resealable plastic bag or shallow dish. Pour the marinade over the steak, ensuring it is well coated. Seal the bag or cover the dish and refrigerate for at least 1 hour, or preferably overnight for better flavor.

Cook the Steak

  1. 3

    Prepare the Grill or Pan

    Preheat your grill to high heat or place a heavy skillet over medium-high heat on the stove.

  2. 4

    Cook the Steak

    Remove the steak from the marinade and allow excess marinade to drip off. Place it on the grill or in the skillet. Cook for approximately 4-5 minutes on each side for medium-rare, or longer if desired for your preferred doneness.

  3. 5

    Rest the Steak

    Once cooked, remove the steak from heat and let it rest for at least 10 minutes before slicing. This allows the juices to redistribute.

Prepare Garlic Mashed Potatoes

  1. 6

    Boil the Potatoes

    In a large pot, bring salted water to a boil. Add the peeled and diced potatoes and cook until tender, about 15-20 minutes.

  2. 7

    Mash the Potatoes

    Drain the potatoes and return them to the pot. Add butter, milk, salt, and black pepper. Use a potato masher or fork to mash until smooth and creamy.

Serve

  1. 8

    Plate the Dish

    Slice the rested porterhouse steak and serve alongside a generous scoop of garlic mashed potatoes. Enjoy your delicious porterhouse steak meal!
