My family lives on anything made with Hawaiian Rolls. They are perfect for the handheld sandwich that needs to be eaten on the go. My ham sandwiches on Hawaiian Rolls are always a crowd favorite, but it is hard to make them when I am away from home. Not any longer. Crock Pot Hawaiian Ham Sandwiches have no made it possible for me to make these yummy ham sliders for a tailgate, cattle show, or barn meal as long as I have my casserole crock pot. If you don't have a casserole crock pot yet, it is time to get one.
Crock pot Hawaiian roll ham sandwiches are the same warm buttery mustard ham sandwich recipe made with onions, poppy seeds, and Swiss cheese just from the casserole crock pot instead of the oven. If you are going to be making this meal away from home, make the buttery mustard and onion sauce ahead of time or the entire sandwich in advance and then heat them up at the game, fair, or meet.
Crock Pot Hawaiian Roll Ham Sandwiches Ingredients
The crock pot version of these Hawaiian roll ham sandwiches is exactly the same recipe as the original oven-baked version plus a little bit more butter. You will need a package of 12 Hawaiian Sweet Rolls, a pound of thinly sliced ham, swiss cheese, butter, onions, mustard, and poppy seeds to make these ham sandwiches.
Start by making the butter and onion sauce on the stove. While the onions are cooking in the butter, put a tablespoon of butter in the bottom of the casserole crock pot and start to the heat on high. Then when the onions are translucent in the butter add the mustard and poppy seeds. Set aside while you cut the rolls in half. Place the bottom half in the melted butter in the crock pot.
Then layer the buttery onion sauce on the bottom rolls followed by the ham, cheese, and buttery onion sauce again. Finally, top the ham and cheese with the roll tops. Use any leftover onion butter sauce to spread over the top of the buns.
