These tasty Cheeseburger Sliders are perfect for a quick and easy meal. With juicy beef, melty cheese, and all your favorite toppings, you won't be able to resist these delicious mini burgers.
Heat a skillet over medium heat and add the vegetable oil. Once heated, add the ground beef and chopped onion.
Break apart the beef with a wooden or silicone spatula. Season with salt, pepper, and garlic powder. Mix everything together in the pan, and cook until the beef is browned.
Drain the grease from the beef and set aside.
Preheat the oven to 350 degrees F and butter/grease the bottom of a baking sheet.
Without separating the individual buns, cut the buns in half horizontally to create two sheets: top buns and bottom buns.
Spoon the ground beef onto the bottom buns and spread it in an even layer. Add a slice of cheese to each burger, overlapping the slices for extra cheesiness.
Place the top buns over the cheese. Melt the butter in a microwave-safe bowl and spread it over the tops of the buns. Sprinkle with sesame seeds.
Bake for 10-12 minutes in preheated oven, or until the buns are golden brown.
Remove and allow to sit a few minutes before serving!
