Notes
This recipe is easy to whip up in a hurry for a crowd – making it the perfect food for any occasion.
Pro Tips
Slice Rolls - You can slice the rolls with a knife or tear them apart with your hands. We recommend slicing with a knife for an even cut.
Melted Butter - For the melted butter on top of the rolls, you can use salted or unsalted. We like the salted to give it a hint of salty flavor.
Foil - If the tops of the rolls get a little too brown before everything is heated, you can top the pan with a piece of foil.
Keeping Warm - After these are done cooking, I cover them with foil over the baking dish to keep these sliders warm and perfect during any party or during the entire game.
Make Ahead - To make these sliders ahead of time, just prepare as indicated without the topping and place in the refrigerator in an airtight container with wrapped with plastic wrap. Then when you are ready to serve, top with the melted butter mixture and bake.
Substitutions
Change out the Ham - As you you probably know, I am not a HUGE ham fan. My entire family loves ham, but my lunch meat of choice is turkey. I've made this exact recipe with turkey and I love it even more. Roast beef would also be a great substitute.
Switch the cheese - in this recipe, I love using provolone, but mozzarella, cheddar cheese, or pepper jack would be amazing.
Change the topping - I love the mustard glaze, but you can leave out the mustard and stir in garlic for another delicious flavor idea.
Poppyseed - You can leave out the poppyseeds if you want. Mix together the slider topping together leaving out the poppyseeds and you will still have an amazing recipe. You can also mix in Everything but the Bagel Seasoning.
