Step 1Heat a large pot or a Dutch oven greased with ghee over a medium-high heat. Pat dry the oxtails with a paper towel and sprinkle with salt and pepper. Place the oxtails in the pot and brown on all sides for about 10 minutes.
You can also use a slow cooker. After browning the meat, transfer it into the slow cooker and cook on high for 4 hours and add the vegetables for the 60-90 minutes of the cooking process.
