Begin by preparing the onions. Finely chop or slice 2-3 large onions, allowing their natural sweetness to shine through.
In a mixing bowl, whisk together the dry ingredients—flour, baking powder, and a generous pinch of salt and pepper.
In a separate bowl, crack open the eggs and give them a good beating. Then, pour in the milk and mix well.
Gradually pour the wet ingredients into the dry mixture, stirring gently until all the ingredients come together.
Now, fold in the chopped onions carefully, ensuring they are evenly coated in the batter.
Heat about ½ inch of vegetable or canola oil in a large skillet over medium-high heat, aiming for around 350°F.
Once the oil is hot, scoop spoonfuls of the onion batter into the skillet, flattening them slightly. Fry each fritter for about 3-4 minutes on each side.
As your crispy Amish onion fritters finish frying, transfer them to a plate lined with paper towels to drain any excess oil.
