Ingredients
Scale
Sliders
- 12 standard or 24 small soft white roll slab (23 x 33cm / 9 x 13″ slab)
- 1/3 cup American mustard (bright yellow mustard)
- 350g / 12 oz ham, shaved or thinly sliced (up to 500g / 1 lb optional)
- 250g / 8 oz Swiss cheese or other melting cheese slices (10 – 12 slices)
Onion Poppyseed Butter
- 100 g (7 tbsp) unsalted butter, melted
- 1/4 onion, finely chopped
- 2 tbsp American mustard
- 1 tbsp poppyseeds
- 1 tbsp Worcestershire sauce
- 1 tsp garlic powder (or fresh garlic finely minced)
- 1/2 tsp cooking or kosher salt
- 1/4 tsp black pepper
Instructions
- Preheat Oven: Preheat your oven to 180°C / 350°F (160°C fan-forced). Line the bottom of a 23 x 33 cm (13 x 9 inch) pan with parchment paper to prevent sticking.
- Prepare Savoury Butter: In a bowl, mix together the melted unsalted butter, finely chopped onion, American mustard, poppyseeds, Worcestershire sauce, garlic powder, salt, and black pepper until well combined.
- Assemble Base: Slice the roll slab horizontally to separate the tops and bottoms. Spread the base and lid of each roll generously with the 1/3 cup of American mustard. Place the bottom halves of the rolls in the prepared pan. Layer evenly with the shaved ham and then cover with slices of Swiss cheese. Do not place the top halves yet.
- Bake Topless: Put the pan into the oven and bake uncovered for 10 minutes, or until the cheese has melted and is bubbly.
- Add Lid and Butter: Remove from the oven, carefully place the top halves of the rolls onto the baked bottoms with the melted cheese. Pour or spoon the prepared onion poppyseed butter evenly over the top, making sure all bread surfaces are coated.
- Cover and Bake: Cover the pan tightly with aluminum foil and bake for 20 minutes, allowing the butter to soak into the bread and flavors to meld.
- Pierce and Uncover Bake: Remove the foil carefully. Using a knife or skewer, pierce the intersections where the rolls meet to let the butter seep inside. Return to the oven and bake uncovered for an additional 10 minutes or until the top is crusty and golden brown.
- Serve: Cut the sliders while still hot and serve immediately for the best melt-in-your-mouth experience.
Notes
- Note 1: A soft white roll slab is a rectangular block of rolls connected together that can be sliced horizontally to make sliders. You can also use separate small rolls if preferred.
- Note 2: American mustard refers to the bright yellow, tangy mustard commonly found in U.S. grocery stores.
- Note 3: Ham quantity can be increased up to 500 g / 1 lb for meatier sliders.
- Note 4: Poppyseeds add a nice crunch and visual appeal but can be omitted if unavailable.
- Note 5: Lining the pan with parchment paper helps with easy removal and cleanup.
- Note 6: Baking topless melts the cheese perfectly before adding the butter and covering for deeper flavor soakage.
