Preheat the oven to 350°F.
Butter the bottom of a baking sheet with softened butter. Set aside.
1 Tbsp. softened butter
Heat the olive oil in a medium sized saute pan over medium high heat. Add the onions. Sauté for ~3 minutes, then add in the ground beef. Cook, breaking up the meat, for another 6-7 minutes or until the meat is no longer pink. Drain any excess fat.
1 Tbsp. olive oil, 1/2 white onion, finely diced, 1 lb. ground beef
Add the garlic, Worcestershire, mustard, salt and pepper and stir for another minute.
2 cloves garlic, minced, 1 Tbsp. yellow mustard, 1 tsp. Worcestershire sauce, 1/2 tsp. kosher salt, pepper, to taste
Slice the rolls in half. Place the bottom rolls down on the prepared baking sheet.
1 pack dinner rolls, 12 count (I use King’s Hawaiian Savory Butter Rolls)
Whisk together the melted butter with the salt and garlic powder.
3 Tbsp. butter, melted, pinch of salt and garlic powder
Place 8 slices of cheese down, followed by the meat on top, and then the remaining cheese on top of beef. Try to pack the ground beef together by just patting it down gently with a wooden spoon. It will feel a little messy, but the cheese will keep everything locked in!
16 slices American cheese (I use Boar’s Head)
Cover with top layer of buns. Brush the buns with the melted butter mixture. Add the sesame seeds all over the tops.
2 tsp. white sesame seeds
Bake for 12-15 minutes or until warmed through and the cheese is melted.
Meanwhile, whisk together the ingredients for the sauce in a bowl until combined.
1/2 cup mayonnaise, 1/4 cup ketchup, 2 Tbsp. sweet pickle relish, 2 tsp. sugar, 1 tsp. distilled white vinegar, salt and pepper, to taste
You can brush the rolls with a little more butter once they come out of the oven, if needed. Cut and serve the sliders with the burger sauce and enjoy!
