Hot Ham and Cheese Sliders
Ingredients
- 1 tbsp Worcestershire sauce
- 250 g / 8 oz Swiss cheese slices 10 – 12 slices
- 1 tsp garlic powder or finely minced fresh garlic
- 2 tbsp American mustard for butter mix (Note 2)
- 1/4 tsp black pepper
- 350 g / 12 oz shaved ham up to 500 g / 1 lb acceptable (Note 3)
- 1/4 onion finely chopped
- 1/3 cup American mustard for spreading Note 2
- 12 standard or 24 small soft white rolls, unseparated, 23 × 33 cm slab (Note 1)
- 100 g / 7 tbsp unsalted butter melted
- 1 tbsp poppy seeds Note 4
- 1/2 tsp cooking / kosher salt
- Baking paper for lining the pan Note 5
Instructions
- Heat the oven to 180 °C / 350 °F (160 °C fan). Line a 23 × 33 cm baking dish with baking paper, allowing overhang for easy removal.
- Combine melted butter, onion, 2 tbsp mustard, poppy seeds, Worcestershire sauce, garlic powder, salt and pepper to create a savoury butter mixture.
- Slice the roll slab horizontally, keeping each half intact. Brush both cut faces with the 1⁄3 cup mustard, set the base in the prepared pan, and arrange the ham evenly over it, followed by the cheese. Leave the top half aside for now.
- Bake the open-faced rolls for 10 minutes until the cheese has melted. (Note 6)
- Place the roll lid on top, spoon the butter mixture over every surface, ensuring no spot remains dry.
- Cover the dish with foil and bake for 20 minutes.
- Remove the foil, pierce the points where the rolls meet so the flavoured butter seeps down, then return to the oven, uncovered, for a further 10 minutes until the tops are crisp.
- Lift the slab out using the paper, cut while piping hot, and serve immediately.
