In a large bowl, combine the 2 pounds ground beef, 1 tablespoon dried minced onion,1 teaspoon salt, 1/2 teaspoon ground black pepper, 1 large egg, 3/4 cup breadcrumbs, and 2 tablespoons Worcestershire sauce. Mix until well combined but avoid over-mixing to keep the patties tender.
Divide the mixture into small portions, each about the size of a golf ball. Flatten each portion into a patty that's slightly larger than your slider buns, as they will shrink while cooking.
Preheat your air fryer to 360°F (180°C) for 2-3 minutes.
Place the patties in the air fryer basket in a single layer.
Set cook time for 8-10 minutes, flipping halfway through, or until the patties reach your desired level of doneness.
Place a slice on each patty during the last minute of cooking to let it melt.
Toast the 16 Slider buns if desired. Then place each cooked patty on a bun and add your Your favorite toppings.
Serve the sliders hot for the best taste.
