Gently steam your riced cauliflower in the microwave for 2-3 minutes until it's soft, then let it cool down.
While the cauliflower cools, in a big bowl, whisk together the shredded onion, golden flaxseed meal, garlic salt, one whole egg, and one egg white.
Once the cauliflower is cool, wrap it in a clean cloth or cheesecloth. Squeeze out as much liquid as you possibly can – this is key for crispy hash browns!
Add the drained cauliflower to the bowl with the other ingredients and mix well. If the mixture feels a bit loose when you try to form a patty, just add an extra egg white to help it bind.
Heat the avocado oil in a large skillet over medium heat. Spoon the cauliflower mixture onto the hot pan, pressing down gently with a spatula to shape them into patties. Cook for 2-4 minutes until golden brown on the bottom, then flip and cook for another 2-4 minutes until crispy and browned. Continue with the rest of the mixture.
