In a large bowl, combine the ground beef, dried minced onion, salt, black pepper, egg, breadcrumbs, and 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). This step ensures even cooking of the sliders.

Place the patties in the air fryer basket in a single layer. Depending on the size of your air fryer, you might need to cook them in batches.

Cook for about 8-10 minutes, flipping halfway through, or until the patties reach your desired level of doneness.

If you’re adding cheese, place a slice on each patty during the last minute of cooking to let it melt.

Toast the slider buns if desired. Then place each cooked patty on a bun and add your favorite toppings.

Serve the sliders hot for the best taste.
