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 shaved or thinly sliced ham (up to 500g / 1 lb optional)
- 250g / 8 oz Swiss cheese or other melting cheese slices (10 – 12 slices)
Onion Poppyseed Butter:
- 100g (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), or 160°C fan-forced. Line the base of a 23 x 33cm (13 x 9″) pan with parchment paper to prevent sticking.
- Prepare Savory Butter: In a bowl, thoroughly mix the melted butter, finely chopped onion, American mustard, poppyseeds, Worcestershire sauce, garlic powder, salt, and black pepper until well combined.
- Assemble Sliders Base: Slice the slab of rolls horizontally in half to create a base and lid. Spread the inside of both halves generously with 1/3 cup of American mustard. Place the base of the rolls in the prepared pan, then layer the shaved or sliced ham evenly over them, followed by a layer of Swiss cheese slices. Do not place the lid on yet.
- Bake Topless: Place the assembled base with ham and cheese in the preheated oven and bake for 10 minutes, or until the cheese has melted completely.
- Add Lid and Butter: Remove the pan from the oven and place the top half of the rolls over the melted cheese. Pour or spoon the prepared onion poppyseed butter evenly over the top, making sure to cover all areas.
- Cover and Bake: Cover the pan with aluminum foil and return it to the oven. Bake for an additional 20 minutes to let the butter soak in and the sandwiches heat through.
- Pierce for Soakage: Remove the foil and use a knife or skewer to pierce the intersections where the roll corners meet. This will help the butter soak deeply into the bread.
- Bake Uncovered: Bake uncovered for a final 10 minutes, or until the top is golden brown and crusty.
- Serve Hot: Remove from the oven, cut the sliders while still hot, and serve immediately for best taste and texture.
Notes
- Use soft white rolls cut into a slab for easy assembly and serving.
- Bright yellow American mustard is traditional and gives an authentic tangy flavor.
- Ham quantity can be increased up to 500g (1 lb) for meatier sliders.
- Poppyseeds add a nice crunch and texture to the butter topping.
- Lining the pan with parchment paper helps prevent sticking and makes cleanup easier.
- Don’t place the lid on before melting the cheese to ensure it melts properly without steaming.
