Frozen hamburger patties are a convenient means of creating a main course meal quickly. While typically barbecued, pan fried or broiled, deep frying the patties produces a deliciously browned crust and a tender middle. However, deep frying is one of the most dangerous methods of cooking, because hot oil can burn the user and is highly flammable. Follow the required steps and precautions when deep frying frozen hamburger patties.
Wash hands thoroughly and create a separate area for preparing the beef. While the patties are frozen, they are still raw meat and can contaminate other surfaces with bacteria. Remove any ice or freezer-burned areas from the patties. This prevents extra splatter in the deep fryer. Follow the manufacturer's directions for preparing the deep fryer, typically preheating the oil to 350 degrees Fahrenheit.
Place the patties gently into the prepared deep fryer using a slotted spoon and standing slightly back. Cook the patties according to the time stated on the packaging and to the required internal temperature, removing them using a slotted spoon. Drain after cooking, placing the cooked patties in a rack or on a paper towel to remove excess oil.
The internal temperature of the patties must reach 160 degrees Fahrenheit before serving the meat. Check the temperature by removing one patty and testing it on a separate plate by inserting a meat thermometer into the thickest part of the meat. Do not attempt to take a reading while the patties are in the hot oil as this will create an inaccurate reading and is dangerous.
Be careful when deep frying any foods. The oil used for deep frying is extremely hot and can burn. Using cold foods in a deep fryer can cause more splatter as the frozen water melts and comes into contact with the oil. Wear an apron to protect clothes, and long sleeves to protect arms. Place a fine mesh splatter guard over the top of the cooking burgers to prevent burns and splashing oil.
Cook other frozen meats in the same manner as the patties. However, ensure that they reach their minimum cooked internal temperature, which may differ from the patties, before removing. Alternatively, allow the beef patties to defrost before cooking and then bread them using an egg wash, then rolling them in breadcrumbs or flour before deep frying. This will create a thick, crispy crust on the burger during deep frying.
