Preheat oven to 425ยบ and line a baking sheet with parchment. On a box grater or in a food processor, grate cauliflower. In a kitchen towel ring out excess liquid from cauliflower.
Transfer cauliflower to a large bowl with eggs, 1 cup mozzarella, Parmesan, ranch seasoning, and season with salt and pepper. Stir until completely combined.
Transfer dough to prepared baking sheet and pat into a crust. Bake until golden and dried out, 25 minutes.
Sprinkle with remaining mozzarella, bacon, and parsley and bake until cheese is melted, 5 to 10 minutes more. Drizzle with ranch, slice and serve.
