In a large bowl, combine the ground beef with the grated carrot, shallot, and garlic.
Add the onion powder, garlic powder, Italian seasoning, chili flakes, black pepper, and salt to the meat mixture.
In a separate bowl, mix the bread crumbs, milk, beaten egg, grated Parmesan, and tomato paste until well combined.
Combine the wet mixture with the meat mixture and mix until everything is evenly incorporated.
Form the mixture into meatballs of your desired size.
Cook the bucatini according to the package instructions until al dente.
In a skillet, heat some oil and cook the meatballs until they are browned on all sides and cooked through.
Serve the meatballs over the bucatini, garnished with additional Parmesan if desired.
