Tips:
- To make sure the patties are cooked through, cut into one with a knife to check for pinkness.
- If you don't have bread crumbs, you can substitute crushed crackers or cereal.
- If you don't have Parmesan cheese, you can substitute another type of hard cheese, such as Romano or Asiago.
- For a richer flavor, use homemade beef broth instead of store-bought.
- To make this recipe gluten-free, use gluten-free bread crumbs and all-purpose flour.
