1 1 / 2 lbs (680 g) porterhouse steak 2 large portobello mushrooms 3 cloves garlic, minced 1 yellow onion, sliced 2 tbsp (30 ml) olive oil Salt to taste Pepper to taste 1 tsp (1 g) fresh thyme (optional)
1. **Prepare the Steak** - Remove the porterhouse steak from the refrigerator about 30 minutes before cooking to allow it to reach room temperature. Season both sides generously with salt and pepper. 2. **Prepare the Mushrooms and Onions** - Clean the portobello mushrooms with a damp cloth and remove the stems. Slice the mushrooms into thick strips. Heat a tablespoon of olive oil in a pan over medium heat. Add the sliced onions, cooking until they become translucent. 3. **Cook the Garlic Mushrooms** - To the pan with the onions, add the minced garlic and sliced portobello mushrooms. Sauté for about 5-7 minutes until the mushrooms are golden and tender. Add salt, pepper, and fresh thyme to taste. 4. **Grill the Steak** - Preheat your grill to high heat. Once hot, place the porterhouse steak on the grill. Cook for about 4-5 minutes per side, or until it reaches your desired level of doneness. Use a meat thermometer for accuracy (130°F for medium-rare, 140°F for medium). 5. **Rest and Serve** - Once cooked, remove the steak from the grill and let it rest for at least 5 minutes to allow juices to redistribute. Serve the steak with the garlic portobello mushrooms and caramelized onions on the side. 6. **Garnish and Enjoy** - Optionally, garnish with fresh thyme for added flavor. Serve hot and enjoy your classic grilled porterhouse steak dinner.
