Step 1Heat the oven to 325 degrees.
Step 2Combine the beef, carrots, onion, salt and pepper to taste, garlic, garlic powder, hot sauce, sun-dried tomatoes, mushrooms and bread crumbs in a large bowl, mixing well. Shape the mixture into a mound and place the meatloaf in a small metal roasting pan.
Step 3Drizzle the wine and broth around the loaf and scatter garlic cloves about. Bake the meatloaf, basting occasionally, until juices run clear when it's pierced with a fork, 40 minutes. Place the meatloaf on a platter and keep it warm. Return the pan to the oven and bake the garlic until it's tender, 10 to 15 minutes.
Step 4Strain the pan juices into a serving bowl. Squeeze the garlic from its skin and add it to the bowl. Serve the pan juices and garlic on the side with the meatloaf.
