How can I slow cook a tri tip in the oven to achieve a tender and flavorful result?

To slow cook a tri-tip in the oven for a tender and flavorful result, season the meat with your preferred spices, sear it in a hot pan, then place it in a roasting pan with some liquid like broth or wine. Cover the pan with foil and cook at a low temperature (around 250F) for several hours until the meat is tender. Let it rest before slicing and serving for the best results.
