Beat the egg, bread crumbs, and Worcestershire sauce until a soft paste forms, and it's thoroughly combined.
Add the ground beef, minced garlic, minced onion, salt, and pepper. If desired, add 1-2 tablespoons of burger seasoning to enhance the flavor.
Thoroughly mix all the ingredients with your hands or a spoon until well incorporated. Avoid overmixing, as it can make the burgers tough.
Divide the mixture into equal portions, depending on how many burgers you want to make. I usually do 4 per pound of beef. Shape into patties, making sure they're of even thickness with a diameter that fits your burger buns.
Before grilling, make a small indentation in the center of each patty with your thumb. This will help the burgers cook more evenly and prevent them from puffing up.
Preheat it according to the manufacturer's instructions. Generally, a temperature of 225-250°F (107-121°C) works well for smoking burgers.
Place the burger patties on the smoker's grates, leaving some space between each patty for proper airflow and smoke circulation.
Close the lid and smoke the burgers for 1-2 hours. The cooking time may vary depending on the thickness of the patties and the desired level of doneness. Ensure the internal temperature of the burgers reaches at least 160°F (70°C) for food safety.
Once the burgers are cooked, remove them from the smoker and let them rest for a few minutes to allow the juices to redistribute.
Serve with your favorite toppings and condiments such as lettuce, tomato, onion, cheese, ketchup, and burger sauce. Enjoy!
