CAN I MAKE IT AHEAD OF TIME? Yes, sort of. You can make the chili a day or two ahead and cook up the dogs ahead of time too. Just make sure to wait to assemble the chili dogs until you are ready to serve them. Putting them together too soon can cause the buns to get soggy. Also, make sure you warm up both the dogs and the chili before assembling the sliders. If you don’t, you could over bake the bread and not heat them all the way through.
