Place the sliced onions into a bowl. Pour the buttermilk over the onions and stir to coat. Let the onions sit in the buttermilk mixture for 30 minutes, stirring once halfway through. Line two baking sheets with paper towels. The towels absorb the excess oil after frying.
Whisk together the gluten-free flour, salt, pepper, garlic powder, and smoked paprika.
Pour the flour mixture into a large zip-top bag. (The mixture can be divided between two bags as needed.)
With tongs or a slotted spoon, transfer the onions to the bag with the flour mixture. Zip the bag completely, then shake to coat the onions in the flour mixture.
Meanwhile, in a large, deep Dutch oven, add oil to fill the pot, about 2-3 inches deep. Heat the oil to 350°F. This will take about 10-15 minutes. (A thermometer attached to the side of the pan is optional but can help maintain the temperature).
Fry the onions in 6 small batches; carefully place a batch of onions into the oil, stirring with a slotted frying spoon so that the onions don’t stick together. Fry until golden brown and crispy, about 4-5 minutes per batch.
Remove the onions and place them on the towel-lined baking sheets. Sprinkle with salt.

To Store: Keep in an airtight container at room temperature for 3-4 days. You can also try freezing them for up to 3 months.
To Reheat: Re-crisp in the oven at 350°F or air fryer for a few minutes, if needed.
