Preheat your oven to 350°F (180°C). Pat the buffalo meat dry with paper towels, then rub it with salt, pepper, and minced garlic.
In a large skillet, heat the olive oil over medium-high heat. Sear the buffalo meat on all sides until it develops a rich golden-brown crust.
Transfer the seared meat to a roasting pan. Add the rosemary sprigs, sliced onions, and pour in the red wine and vegetable broth.
Cover the roasting pan with aluminum foil and roast in the oven for 2 to 2.5 hours, basting the meat with its own juices occasionally.
When the meat is fork-tender, remove it from the oven and let it rest for 10 minutes before slicing and serving, drizzled with the pan juices.
