Preheat the oven to 375 degrees and line a baking sheet with parchment paper.
In a mixing bowl, combine the ground beef, breadcrumbs, egg, onion, garlic, 1/4 cup BBQ sauce, salt, and pepper. Mix until evenly blended.
Divide the mixture into four equal portions and shape each into a small loaf.
Wrap each loaf with two slices of bacon, tucking the ends underneath to hold them in place.
Place the wrapped loaves on the prepared baking sheet and bake for 25 minutes.
Remove the sheet from the oven and brush the tops with the remaining 1/2 cup BBQ sauce.
Return to the oven and bake for another 10 minutes until the bacon is crisp and the internal temperature reaches 160 degrees.
