Preheat your oven to 325°F (165°C).
In a small bowl, mix together the garlic powder, salt, onion powder, paprika, black pepper, dried oregano, and dried thyme to make a spice rub.
Pat the pork butt dry with paper towels to remove excess moisture.
Rub the spice mixture evenly all over the pork, covering it completely.
Place the seasoned pork in a roasting pan or an oven-safe dish.
Cover the roasting pan tightly with aluminum foil to seal in the flavors.
Roast the pork in the preheated oven for about 3-4 hours, or until the internal temperature reaches at least 195°F (90°C). Slow cooking like this will make the pork tender and full of flavor.
Once the pork reaches the desired temperature, remove it from the oven and allow it to rest for about 15-20 minutes. This resting time helps the juices redistribute, making the meat juicier.
After resting, slice the Rainbow Drive Inn Roast Pork.
