Mix the egg, Worcestershire sauce, onion, salt, pepper, garlic and paprika in a bowl to combine. Add the meat and mix until egg and seasonings are evenly distributed.
Heat a large frying pan over medium heat while you divide the meat mixture into 8 even portions and flatten into patties.
Place the patties in the pan, cooking in batches if they don’t all fit at one time. Cook for 4 minutes on each side. Turn the heat down a little if needed to ensure they don’t burn.
Drain any excess grease but keep any fond (the little browned bits of food stuck to the bottom of the pan after searing).
Pour the broth over the patties scraping the bottom of the pan to deglaze it.
Bring the pan up to a boil and then turn down to a simmer and continue to cook until the liquid is reduced by half, approximately 20-25 minutes. Turn the patties every 10 minutes to avoid them drying out.
After the 20-25 minutes of braising, place the patties on a plate to the side.
Mix the cornstarch and water in a bowl and stir until blended. Bring the pan back up to a boil, add the slurry to the pan, stir to combine, lower the heat back to medium and cook for a few minutes to start thickening the sauce.
Place the patties back into the sauce and flip a few times to ensure even coating.
