Recipe Ingredients:
- 3 cups all-purpose flour
- 2 teaspoons baking powder
- 2 teaspoons seasoned salt, plus extra for sprinkling at the end
- 2 teaspoons freshly ground black pepper
- 3 bottles beer
- 6 large eggs
- Vegetable oil, for frying
- 6 large yellow onions, very thinly sliced with a mandoline
How To Make Beer-Battered Onion Strings?
- Prepare the Batter: Mix the flour, baking powder, seasoned salt, and pepper in a large bowl. In a pitcher, whisk together the beer and eggs until well combined. Pour the wet mixture into the dry ingredients and mix until smooth.
- Heat the Oil: In a large, heavy-bottomed pot, pour enough vegetable oil to reach halfway up the sides. Heat the oil to 190°C / 375°F, using a deep-frying thermometer to maintain the temperature.
- Fry the Onion Strings: Working in batches, dip the onion strings into the batter, ensuring they are fully coated. Gently lower them into the hot oil and fry until golden and crispy, about 2 to 3 minutes.
- Drain and Season: Transfer the fried onion strings to a plate lined with paper towels to remove excess oil. While still hot, sprinkle with extra seasoned salt.
- Serve: Enjoy immediately as a crispy side dish or a delicious snack with your favourite dipping sauces

Recipe Tips:
- Keep the Oil Hot: Maintain the oil temperature at 190°C / 375°F for perfectly crispy onion strings. If the oil is too cool, the batter will absorb excess oil and become soggy.
- Slice Onions Thinly: Use a mandoline slicer for ultra-thin and even onion slices. Thinner slices cook faster and become extra crispy.
- Don’t Overcrowd the Pot: Fry the onion strings in small batches to avoid lowering the oil temperature and ensure they cook evenly.
- Drain Properly: After frying, place the onion strings on a plate lined with paper towels to absorb extra oil. This keeps them crisp and not greasy.
- Season Immediately: Sprinkle the onion strings with seasoned salt right after frying. The heat will help the seasoning stick better, enhancing the flavor.
How To Store & Reheat Leftovers?
- Refrigerate: First, let the leftover Beer-Battered Onion Strings cool to room temperature. Then, place them in an airtight container lined with paper towels and refrigerate for up to 3 days.
- Reheat: Preheat the air fryer to 180°C / 350°F. Place the onion strings in the basket in a single layer and heat for 3-5 minutes until they regain their crispiness.
