Turn on an oven to preheat to 350 F (180 C) and spray a thin coating of pan spray on a 7×5 baking dish. Collect the amount of Keto hamburger buns you need for the recipe. Cut each hamburger bun into quarters.
Step 2
Place the bottom pieces of the buns in the base of the baking dish. Slice the ham into thin, julienne pieces. Separate the pieces and arrange the ham over the buns in the dish. Next, cut pre-packaged slices of swiss cheese into quarters and arrange one piece on each slider.
Step 3
Place the top pieces of hamburger buns over the sliders. Then, melt the butter in a small dish. Stir the mustard into the melted butter (it doesn’t have to fully mix together). Use a marinade or pastry brush to brush the mustard butter over the top of each bun. Be generous and use all of the mustard butter.
Step 4
Cover the dish with aluminum foil. Bake the sliders in your oven for 40 minutes or until the cheese melts and the mustard butter completely bakes into the buns and makes them soft. Let the dish of sliders cool for 5-7 minutes before pulling a hot slider out to enjoy.
