Ingredients
-
2 large yellow or sweet onions (about 3 cups chopped)
-
1 cup all-purpose flour
-
1 teaspoon baking powder
-
1 teaspoon salt
-
½ teaspoon black pepper
-
½ teaspoon garlic powder (optional)
-
2 large eggs
-
¼ cup milk or buttermilk
-
Vegetable oil for frying (about ½ inch deep)
Equipment Needed
-
Large mixing bowl
-
Whisk or fork
-
Heavy-bottomed skillet or cast-iron pan
-
Large spoon or scoop
-
Slotted spatula
-
Paper towel-lined plate
Method
1. Prepare the onions
-
Peel the onions and chop them into small, uniform pieces (about ½ inch or 1 cm dice). Do not puree—small chunks give the best texture.
2. Mix the dry ingredients
-
In a large bowl, whisk together the flour, baking powder, salt, black pepper, and garlic powder (if using).
3. Combine wet ingredients
-
In a separate small bowl, beat the eggs and milk together until smooth.
4. Make the batter
-
Pour the wet mixture into the dry ingredients. Stir until just combined—do not overmix. A few small lumps are fine.
-
Fold in the chopped onions until evenly coated. The batter should be thick enough to hold the onions together but not dry. If too thick, add 1 extra tablespoon of milk.
5. Heat the oil
-
Pour vegetable oil into a large skillet to a depth of about ½ inch (1 cm).
-
Heat over medium heat until the oil shimmers. To test, drop a small bit of batter into the oil—it should sizzle immediately and rise to the surface.
6. Fry the fritters
-
Using a large spoon or scoop, drop spoonfuls of the onion batter into the hot oil. Gently flatten each fritter slightly with the back of the spoon so they cook evenly.
-
Do not overcrowd the pan—cook 3 to 4 fritters at a time.
-
Fry for 2 to 3 minutes per side, until golden brown and crispy.
-
Use a slotted spatula to flip carefully.
7. Drain and serve
-
Transfer the finished fritters to a paper towel-lined plate to drain excess oil.
-
Serve warm.
Serving Suggestions
-
Plain with a sprinkle of salt
-
With sour cream or Greek yogurt
-
With applesauce (a traditional Amish pairing)
-
With ketchup or ranch dressing
-
As a topping for burgers or sandwiches
Storage
-
Refrigerator – store in an airtight container for up to 3 days.
-
Freezer – freeze in a single layer on a baking sheet, then transfer to a bag for up to 2 months.
-
Reheating – warm in a 180°C (350°F) oven for 5–10 minutes, or in an air fryer until crispy. Do not microwave—they will become soggy.
Variations
-
Cheese onion fritters – add ½ cup shredded cheddar or Parmesan cheese to the batter.
-
Herbed onion fritters – add 1 tablespoon of fresh chopped parsley, chives, or dill.
-
Spicy onion fritters – add ¼ teaspoon cayenne pepper or red pepper flakes.
-
Sweet onion fritters – add 1 tablespoon of sugar and serve with powdered sugar for a sweet-savory treat.
-
Zucchini onion fritters – replace half the onions with grated zucchini (squeeze out excess moisture first).
-
Gluten-free – use a 1:1 gluten-free baking flour blend instead of all-purpose flour.
Tips for Best Results
-
Use sweet onions (like Vidalia or Walla Walla) for the mildest, sweetest flavor. Yellow onions work well too; red onions are slightly sharper.
-
Chop onions small, not large chunks – small pieces cook through evenly and help the fritters hold together.
-
Do not overmix the batter – overmixing develops gluten and makes tough fritters instead of tender ones.
-
Keep the oil at medium heat – too hot and the outside burns before the inside cooks; too cool and the fritters absorb oil and become greasy.
-
Drain well – let the fritters rest on paper towels for a minute before serving to remove excess oil.
-
Serve immediately – fritters are best hot and crispy. They will soften as they cool.
