Preheat your grill to medium-high heat or preheat your oven to 375°F (190°C).
In a small bowl, combine the thyme leaves, rosemary leaves, minced garlic, olive oil, salt, and pepper to create the herb crust mixture.
Pat the pork shoulder steaks dry with a paper towel and season them with salt and pepper. If they’re frozen, thaw them first.
Cover both sides of the pork shoulder steaks with the herb crust mixture evenly, and press gently to ensure the rub adheres to the meat.
If grilling, place the steaks on the preheated grill and cook for about 4-5 minutes per side, or until the internal temperature reaches 145°F (63°C) for medium doneness. If oven-roasting, place the steaks on a baking sheet and cook for approximately 25-30 minutes, or until the internal temperature reaches 145°F (63°C). Use a meat thermometer to ensure the steaks are cooked inside.
Remove the pork shoulder steaks from the heat, rest for a few minutes, then serve with your favorite side dishes.
