Heat butter in a large skillet over medium-high heat and add the two pounds of ground beef with garlic powder, onion powder, salt, and black pepper. Cook for 8-10 minutes, breaking the meat into small crumbles as it browns, then stir in Worcestershire sauce and beef broth.

Simmer the beef mixture for 2-3 minutes until the broth reduces slightly and flavors meld together. The mixture should look moist but not soupy; adjust by simmering longer if excess liquid remains.

Toast your slider buns lightly under the broiler for 1-2 minutes to add structure and prevent sogginess from toppings. This step prevents crowd sliders from falling apart during handling.

Spread the spiced mayo mixture (combine mayonnaise, mustard, and hot sauce in a small bowl) on the bottom half of each bun. Layer lettuce, tomato slices, and a generous spoonful of the loaded game day sliders recipe beef mixture onto each bun.

Top each slider with shredded cheddar cheese while the beef is still hot so it melts slightly, then add caramelized onions and crispy turkey strips. Crown with the toasted top bun and serve immediately for optimal texture.
