Heat a large skillet over medium-high heat. Add the ground beef in an even layer and season immediately with granulated garlic, kosher salt, and black pepper. Cook while breaking up the meat with a spatula, allowing caramelized edges to develop and ensuring an even crumb texture.
02 -
Incorporate the diced yellow onion into the partially browned beef. Continue to cook, stirring occasionally, until the onions are translucent and the mixture is well browned.
03 -
Pour Dr. Pepper barbecue sauce over the cooked beef and onion mixture. Stir thoroughly to coat the filling evenly; allow the sauce to bubble and begin thickening, adjusting heat to medium if necessary.
04 -
Reduce heat to low and cover the skillet. Let the mixture simmer gently for 5 minutes so the sauce infuses the beef and achieves optimal sloppy consistency.
05 -
Keep the mixture warm over low heat until ready to assemble. If desired, transfer to a slow cooker set to warm for extended holding.

Spoon the hot, saucy filling generously onto split sandwich buns. Serve immediately for best texture.
