Preheat the oven to 325ºF. Line a baking sheet with parchment paper.
In a large bowl, combine the almond flour, Parmesan cheese, chives, parsley, baking soda, and salt. In another bowl, whisk the eggs then add in the sour cream or yogurt, garlic, onion, and water. Add the wet ingredients to the dry and mix well. The batter will be wet and goopy (yes, “goopy” is a technical culinary term!). Using a spoon, scoop a generous amount onto the parchment-lined baking sheet in the size you want your biscuit to be. Repeat using remaining batter. If you want large sandwich-like buns, make large biscuits and only 4 per sheet.
Bake for 15-18 minutes. You can flip them after about 10 minutes if you want both sides browned, but this is optional. Store loosely wrapped in aluminum foil or in the refrigerator. (These reheat well in the oven. I also like to toast mine before eating each time.)
