Preheat your oven to 350°F (175°C) and prepare a muffin tin by lining each cup with paper cupcake liners to prevent sticking.
In a large mixing bowl, combine the ground beef, breadcrumbs, finely chopped onion, grated Parmesan cheese, ketchup, Worcestershire sauce, Dijon mustard, beaten egg, garlic powder, smoked paprika, and a generous seasoning of salt and pepper. Using your hands or a spatula, mix thoroughly until all components are well blended and evenly distributed.
Carefully scoop the meat mixture into each prepared cupcake liner, filling them about three-quarters of the way full to allow for expansion during cooking.
Place the muffin tin in the preheated oven and bake for 25 to 30 minutes, or until the internal temperature of the meatloaf cupcakes reaches 160°F (71°C) on a meat thermometer. Ensure you check a few to confirm they are fully cooked.
Upon completion of baking, remove the muffin tin from the oven and allow the cupcakes to cool for about 5 minutes. Meanwhile, drizzle a layer of your favorite BBQ sauce over the top of each meatloaf cupcake for an extra burst of flavor.
Return the meatloaf cupcakes to the oven for an additional 5 to 10 minutes, allowing the BBQ sauce to caramelize slightly, creating a delightful glaze.
Once caramelized to your preference, remove from the oven and permit to cool for another few minutes. Carefully lift the cupcakes out of the muffin tin, ensuring they retain their shape.
Just before serving, garnish each cupcake with a sprinkle of freshly chopped parsley for a vibrant touch and a hint of freshness.
Notes
Serve with a fresh side salad and extra BBQ sauce for dipping.
