Recipe video above. You can't imagine how good a ham sandwich can be until you've tried Hot Ham and Cheese Sliders! Rolls stuffed with ham and cheese smothered in a tangy mustard onion butter sauce baked until the cheese is melty, this American game-day favourite is excellent big-batch party food that is leftover Christmas ham-worthy. The mustard and onion really works in this, lending savouriness and tang that sets this apart from the usual boring lunchbox ham sandwiches! And there's probably less butter per roll (1 3/4 tsp each) than if you spread it on like usual. (Did I just convince myself this is healthy? 🤣)
Preheat oven to 180°C / 350°F (160°C fan-forced). Line the base of a 23 x 33cm / 13 x 9" pan with paper (Note 5)
Savoury Butter - Mix ingredients together.
Assemble base - Cut the slab of rolls in half horizontally. Spread base and lid with the 1/3 cup mustard. Place bread in pan, top with ham then cheese. NO LID YET!
Bake topless - Bake 10 minutes until the cheese is melted. (Note 6)
Smother - Remove bread from oven. Top with bread lid, pour/spoon over butter, leaving no patch naked.
Bake covered - Cover with foil, bake 20 minutes.
Pierce for soakage - Remove foil. Pierce the intersections where the corners of the rolls meet to encourage pooled butter to soak into the bread.
Bake uncovered for 10 minutes or until top is crusty.
Cut while hot then serve!
