Preheat the oven to 350 degrees F (175 degrees C). Line a rimmed baking sheet with parchment paper.

Combine ground beef, eggs, bread crumbs, Parmesan cheese, parsley, garlic, onion powder, salt, black pepper, oregano, and basil in a large bowl; form into 2-inch meatballs.

Wrap 1 half-slice bacon around 1 meatball; turn meatball 45 degrees and wrap 1 half-slice bacon around meatball to enclose. Repeat with remaining bacon and meatballs, forming 12 meatballs, wrapping each with 2 half-slices bacon. Place meatballs onto the prepared baking sheet, seam sides down.

Bake in the preheated oven until meatballs no longer pink inside and bacon crisp, about 45 minutes. An instant-read thermometer inserted into centers should read at least 160 degrees F (70 degrees C). Pour off excess grease.
