Prepare the Ground Beef: Start by placing the ground beef in a bowl. Season it with salt, pepper, and garlic powder (optional). Mix gently until combined. Form the mixture into 6 small, even patties, making sure they fit the size of your slider buns.
Preheat the Air Fryer: Preheat your air fryer to 375°F (190°C). This will ensure that your sliders cook evenly and develop that crispy texture on the outside.
Air Fry the Beef Patties: Place the beef patties in the air fryer basket in a single layer, ensuring they are not touching each other. Air fry the patties for about 6 minutes. After 6 minutes, flip the patties and continue air frying for another 2 minutes, or until they reach your desired doneness.
Toast the Slider Buns: While the patties are cooking, cut the slider buns in half. After the patties are done, place the buns in the air fryer for about 2 minutes at 375°F (190°C) to toast them lightly. This will add a nice crispness to the buns, which complements the juicy sliders.
Assemble the Sliders: Once the patties and buns are ready, assemble the sliders. Place a beef patty on the bottom half of each bun. Add a slice of cheese on top of the patty while it is still hot to allow it to melt. Then, top with a pickle slice, a small lettuce leaf (if desired), and a dollop of ketchup or mustard.
Serve and Enjoy: Place the top half of the buns on the assembled sliders and serve immediately while they’re hot and crispy!
