1-First Step: Preheat your oven to 350°F and lightly coat a 9×13 baking dish with nonstick spray. This ensures the sliders don’t stick and helps with even cooking, setting the stage for that perfect buttery base.

2-Second Step: In a small bowl, mix together the Big Mac sauce ingredients: 2/3 cup mayonnaise, 2 1/2 tablespoons sweet pickle relish, 2 teaspoons sugar, 1 1/2 tablespoons yellow mustard, 1/2 teaspoon paprika, 1/2 teaspoon onion powder, and 1/4 teaspoon garlic powder. Stir until smooth, then set it aside to let the flavors blend while you prepare the rest.

3-Third Step: In a skillet over medium heat, cook 1 pound of lean ground beef along with 1/4 cup finely chopped white onion, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Stir until the beef is no longer pink and the onions soften, which takes about 8-10 minutes, then drain any excess liquid to keep the mixture from getting too greasy.

4-Fourth Step: Place the bottoms of the 12 slider buns in the prepared baking dish. Spread a thin layer of the Big Mac sauce over them, then evenly add the cooked beef mixture on top, followed by the 9 slices of American cheese arranged to cover as much as possible, and finally, layer on the 24-30 dill pickle slices.

5-Fifth Step: Bake the assembled bottoms in the preheated oven for 8-10 minutes. This melts the cheese nicely and lets the flavors start to merge, creating that gooey, warm center.

6-Sixth Step: Remove the dish from the oven and add 2 cups of shredded lettuce on top of the melted cheese, along with another layer of Big Mac sauce for extra moisture. Then, place the tops of the slider buns over everything to complete the sliders.

7-Seventh Step: Brush the tops of the buns with 2 tablespoons of melted butter and sprinkle 2 tablespoons of sesame seeds over them for that authentic finish. Cover the dish with foil and bake for another 10 minutes, or until the cheese is fully melted and the buns are golden.

8-Final Step: Take the sliders out of the oven and let them cool for a minute or two before serving warm.
