These sliders are freezer friendly! Make a batch or two without the garlic butter and freeze on a baking tray before putting into a freezer-safe bag and keeping in the freezer for up to 6 months. Thaw in the fridge, slather in garlic butter sauce, and pop into the oven at 325ºF for about 20-25 minutes or until the sliders are completely heated, the cheese is melted, and the tops are golden brown.
