Hamburger Mixture

• Add the ground beef, Worcestershire sauce, seasoned salt, and hamburger seasoning. Cook the beef for 8-10 minutes, or until no longer pink, breaking up the beef with a wooden spoon. Remove from heat; drain any excess grease as necessary.

Assembly

• Split your rolls in half horizontally and place the bottom halves in the baking dish.
• Evenly pour about 2 tablespoons of cowboy butter over the bottom halves of the bread in the pan.
• Top with the hamburger mixture.
• Evenly place the jalapeños, bacon, and shredded cheese over the sliders. Evenly distribute the crispy fried onions over the cheese.
• Place the top halves of the rolls on top of the fried onions. Brush the tops of the rolls with melted cowboy butter*.
• Cover the dish with aluminum foil and bake for 15 minutes, or until the cheese is hot and bubbly.
• Remove the foil and bake for an additional 3-5 minutes (or until the tops of the sliders turn a golden brown).
• Remove from oven. Slice and serve the sliders with the remaining cowboy butter brushed over the hot sliders or for dipping.
