All ingredients ready? Let's begin!
Preheat oven to 350F. Spray a 9x9-inch or 9x13-inch pan with cooking oil, or coat it with melted butter.
Use a large serrated knife to slice the rolls in half so that you have one layer of tops and one layer of bottoms. Don’t pull the rolls apart, you want to keep them connected.
Place the bottom layer of rolls on the prepared pan.
Melt the butter in a small pot on low heat or in the microwave for about 1 minute. Mix salt, pepper, and Spanish paprika into the butter, and spread about half of the mixture on the bottoms of the rolls. Use a brush.
Evenly layer half of the ham on the rolls.
Evenly layer rolls with cheese. Add the jalapeño peppers if using. Then layer with the remaining ham.
Add the top layer of rolls and set them aside.
Evenly pour the rest of the butter mixture over the rolls. Use a spatula or brush to spread mixture over the tops. It’s normal for some of the mixture to drip at the base of the rolls.
Cover rolls with aluminum foil and let sit at room temperature for 5-10 minutes.
Bake covered for about 20 minutes or until cheese has melted. Uncover and bake for another 3-5 minutes or until the desired result.
Slice into individual sliders and serve immediately. These sliders taste best warm and fresh out of the oven.
