Step 1

Preheat the oven to 350°F. Line a large baking dish with aluminum foil. Spray with cooking spray and set it aside.

Step 2

Slice the rolls in half. Place the bottom slab of rolls in the prepared pan.

Step 3

Add the sliced ham on the rolls. Then add a layer of cheese.

Step 4

Add the top slab of the rolls; set aside.

Step 5

In a medium sized microwave safe bowl, add the butter and heat it on high for about one minute until melted.

Step 6

Add the mustard, poppy seeds, onion, Worcestershire sauce, salt, and pepper. Whisk until combined.

Step 7

Slowly pour the butter mixture over the rolls and use a spatula to spread the mixture all over the tops. Some of the butter will pool at the bottom of the rolls.

Step 8

Cover the pan with foil and let the rolls rest at room temp for 5 to 10 minutes.

Step 9

Bake covered for about 20 minutes or until the cheese has melted.

Step 10

Uncover the pan and bake for 3 to 5 minutes until golden brown. Be sure to watch the rolls carefully so they don’t burn.

Step 11

Slice the rolls into individual sliders and serve while they’re still warm.
