Bring a large pot of salted water to a boil. Add the cauliflower florets and cook until fork tender, 5 to 10 minutes. Thoroughly drain the florets and transfer them to a food processor. Pulse the cauliflower until it breaks down into small, rice-sized pieces. Avoid overmixing.

Measure out 3 packed cups of the processed cauliflower and add to a large bowl. Stir in diced onion, Parmesan cheese, breadcrumbs, egg, 1 teaspoon salt, and 1/4 teaspoon pepper. Mix until thoroughly combined to achieve a mashed-potato-like consistency.

Using your hands, scoop up 1 to 2 tablespoons of the mixture and mold into a tater tot shape. Place on the prepared baking sheet, spacing the tots about 1 inch apart. Repeat with the remaining mixture.

Bake the tots for 20 minutes, then flip them and bake for an additional 10 to 15 minutes until crisped. Remove and serve with ketchup, pesto, hummus, or your preferred dipping sauce.

To air-fry the tots, preheat the air fryer to 400°F. Coat the basket with cooking spray and add a batch of tots. Air-fry for 6 minutes, flip, and air-fry for an additional 3 to 5 minutes until golden brown and crispy.
