Place a large cast iron skillet over medium heat. Once hot, add ghee. Sprinkle salt and garlic powder on all sides of each short rib then place the the pan and sear on all sides, about 2-3 minutes per side, until a nice crust appears on the short ribs.
In a crockpot, place garlic cloves, onion, carrots, and celery in the bottom. Add the seared short ribs on top. In a bowl, whisk together red wine, broth, and tomato paste. Pour mixture on top of short ribs then add bay leaves, thyme, rosemary, and red pepper flakes to crockpot. Lastly, add mushrooms to the top. Cover and cook on low for 8 hours.
When cooked fully and falling off the bone, garnish with fresh parsley and flaked salt.
