Prepare the oven and cauliflower. Preheat the oven to 400°F (200°C).
Cook the cauliflower florets by steaming or boiling them until tender, approximately 5–7 minutes. Drain thoroughly and allow the cauliflower to cool slightly.
Mash and combine. Transfer the cooled cauliflower to a mixing bowl and mash it until smooth.
Add the cottage cheese, egg, garlic powder, onion powder, salt, and black pepper. Stir thoroughly until the ingredients are evenly incorporated.
Shape the tots. Gradually work the breadcrumbs into the cauliflower mixture. The finished mixture should hold together firmly enough to shape without becoming excessively dry.
Scoop out small portions and form each one into a tot shape. Keep the pieces approximately equal in size to promote consistent baking.
Bake. Arrange the shaped tots on a parchment-lined baking sheet.
Bake in the preheated oven for 20–25 minutes, or until the tots develop a crisp texture and an evenly golden-brown exterior.
Serve. Remove the baked tots from the oven and allow them to cool briefly before serving.
