Preheat a convection oven to 400°F (204°C) and line a rimmed baking sheet with parchment paper.
In a stainless steel mixing bowl, combine the ground beef, chopped bacon, shredded cheddar, breadcrumbs, and beaten egg.
Incorporate the Worcestershire sauce, garlic powder, onion powder, salt, and pepper into the mixture.
Gently fold the ingredients together by hand until a homogenous mixture is achieved, avoiding over-compression of the meat fibers.
Portion the mixture into 1.5-inch spheres, approximately 40 grams each, and place on the prepared baking sheet with 1 inch of separation.
Transfer the baking sheet to the center rack of the oven and roast for 18 to 20 minutes.
Monitor the internal temperature until a probe thermometer registers a minimum of 160°F (71°C).
Remove from the heat source and allow the meatballs to rest for 5 minutes to facilitate juice redistribution before service.
