Grate the cauliflower using a box grater or food processor, then place it in a clean kitchen towel and squeeze out as much moisture as possible over the sink.
In a large bowl, combine the squeezed cauliflower, beaten eggs, shredded cheese, almond flour, garlic powder, onion powder, salt, and pepper, mixing until well combined.
Heat 1 tablespoon of oil in a large non-stick skillet over medium heat.
Form the cauliflower mixture into patties about 3 inches wide and 1/2 inch thick, placing them carefully in the hot skillet.
Cook for 4-5 minutes on each side until golden brown and crispy, adding more oil as needed between batches.
Transfer cooked hash browns to a paper towel-lined plate and serve immediately while hot and crispy.
