These cheeseburger sliders capture the nostalgic flavors of a classic cheeseburger perfectly. Hawaiian rolls are loaded with cooked ground beef, cheddar cheese, and caramelized onions and baked to melty perfection.
Caramelize the onions. Heat the olive oil in a large, heavy-bottomed skillet over medium heat, add the onions, and season with salt. Saute until they start to soften a bit. Turn the heat to medium-low and let the onions cook until they are very soft and golden brown, stirring occasionally. This process should take about 45 minutes.
For the Beef
Prep. While the onions are caramelizing, preheat the oven to 350°F and grease a 9X13 baking dish with olive oil.
Season the beef. In a medium-sized mixing bowl, combine the beef, onion powder, garlic powder, salt, and pepper. Use your hands to mix everything together until well combined.
Bake the beef. Press the beef mixture into a thin, even layer on the bottom of the prepared baking dish. Bake for 15 to 17 minutes or until cooked through. Drain the grease from the dish and set aside.
For the Sliders
Prepare the rolls. Cut the whole sheet of Hawaiian rolls in half, horizontally through the center, without breaking the individual rolls apart. Arrange them cut side up on a baking sheet lined with parchment paper and brush both sides of the rolls with Thousand Island dressing.
Assemble the sliders. Arrange the cooked beef over the bottom half of the rolls, spread the caramelized onions over the top in an even layer, and then sprinkle the cheese evenly over the onions. Top the sliders with the other half of the rolls. Brush the tops of the rolls with the melted butter and sprinkle with sesame seeds.
Bake. Bake the sliders for 6 to 10 minutes or until the cheese is melted.
