During the cooking process, these pizza bites will start to look oily – that’s normal! They will absorb most of the oil by the time they’re done cooking. This wasn’t an issue for me, but if you’re concerned about grease dripping onto the bottom of your oven, you can place a piece of foil on the rack under the muffin tray to catch any drips as these cook. And if you want to remove the excess grease, after they’re cooked transfer them to a paper towel-lined plate.
