Baked Cheeseburger Sliders with Hawaiian Rolls

Preheat the oven to 350°F (177°C). Grease a small sheet pan and set it aside for later.

Add the ground beef, Kosher salt, onion powder, garlic powder, paprika, cayenne, Worcestershire sauce, and black pepper to a big mixing bowl. Mix everything together just until the meat is well-combined. Don't over-mix!

Transfer the meat mixture to the prepared sheet pan. Then, pat it into a big, evenly-thick rectangle that's roughly the same size as the Hawaiian rolls. Bake the beef patty for 15 minutes, or until it's browned and mostly cooked through. (It'll finish cooking later.) Drain off any grease. Then, use paper towels to pat any extra grease or liquid off of the beef patty.

While the beef patty is baking, heat the olive oil in a large skillet over medium heat. Add the onions along with a big pinch of salt and black pepper, to taste.

Sauté the onions, stirring often, until they're softened and golden-brown, about 8-10 minutes. Let the onions cool slightly.

Cut the rolls in half horizontally, leaving the bottom and top halves intact. Place the bottom half of the rolls on a small greased sheet pan.

Place a layer of cheese on the bottom rolls to keep them from getting soggy. Then, add the beef patty, another layer of cheese, and the sautéed onions. Place the top rolls over the patty mixture. Use a pastry brush to brush the top rolls with melted butter. Sprinkle the sesame seeds over the top.

Then, wrap the sliders with foil. Bake the sliders for about 15 minutes. Then, uncover and bake them for another 5-6 minutes, until the tops are golden-brown and the internal temperature of the patty reaches 165°F (74°C). Slice and serve with pickles, ketchup, and mustard. Enjoy!
