Preheat the oven to 350 degrees Fahrenheit (or whatever temperature you’re cooking your bird at.)
Using the shredding attachment of a food processor or a cheese shredder, shred the zucchini. Squeeze out the excess water using a few paper towels and set aside.
Melt the butter in a large sauté pan over medium heat, then add the shredded zucchini and garlic. Sauté until garlic is translucent and fragrant, then turn heat to low.
In a clean food processor fitted with the blade attachment, make your fresh breadcrumbs using whatever type of bread you have on hand. Add fresh basil at the very end just to give it a rough chop.
Stir breadcrumb mixture into zucchini mixture, then transfer into a baking dish, or stuff into your bird. Bake at desired oven temperature for about an hour, or until the surface of the stuffing takes on a nice golden-brown color.
Serve with your holiday meal!
