Place the ground beef, onion, egg, 2 tablespoons barbecue sauce, oats, pepper and cheese together in a large bowl and mix until combined.
Line a baking sheet with parchment paper or aluminum foil. Divide the mixture into four equal portions and form them into loaves on the baking sheet. Brush each meatloaf with 1 tablespoon barbecue sauce.
Bake 22–25 minutes until cooked through. Cool meatloaves slightly before serving.
Notes
If you don’t have quick-cooking oats, you can make them by pulsing old-fashioned oats in a food processor until coarsely ground.
