Preheat the oven to 350 degrees Fahrenheit. Place a 6-compartment muffin tin on top of a foil-lined cookie sheet.
Mix all ingredients together in a large mixing bowl until the spices are evenly dispersed. Divide into six equally-sized balls and place each one in a muffin tin compartment, making sure to avoid gaps or air bubbles.
Place the cookie sheet with the muffin tin on top in the oven and bake for 30 minutes. Remove from the oven and carefully remove each meatloaf from its compartment, placing it upright on the cookie sheet. If the juices are running clear, skip to the next step. If not, bake them for another 10 minutes, then remove the sheet from the oven.
Place an oven rack in the 2nd from the top position in your oven, then turn on the broiler. Put the cookie sheet with the meatloaves on that rack and broil for 3-4 minutes, until the meatloaves are golden brown. Remove from the oven and serve.
