Begin by arranging two racks to divide the oven into thirds and preheat it to 350°F. Line a baking sheet with foil for easy clean-up.
If you have leftover homemade or store-bought dinner rolls, slice them in half horizontally, brush both halves with the garlic butter, then bake on the lower rack until warm, 8 to 10 minutes.
Transfer to the upper rack and broil until the edges of the rolls are toasty, 1 to 2 minutes.
If you’re starting with frozen dinner rolls, brush the garlic butter on top of the rolls and bake according to package directions. Then, broil them for 1 to 2 minutes until toasty.
