Equipment
- Large heavy-bottomed pot or deep skillet
- Cooking thermometer (very important)
- Mixing bowls (2 medium, 1 large)
- Whisk
- Tongs or slotted spoon
- Wire rack
- Paper towels
- Sharp knife
- Cutting board
Ingredients
- 2 large sweet onions such as Vidalia, sliced into 1/2-inch rings
- 1 1/2 cups all-purpose flour divided
- 1 tablespoon cornstarch
- 1 teaspoon baking powder
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon paprika
- 1/2 teaspoon garlic powder
- 1 1/4 cups cold sparkling water or cold club soda
- Vegetable oil for frying about 3–4 cups
Instructions
Step 1: Prepare the Onions
- Peel the onions and slice them into 1/2-inch thick rounds. Carefully separate the rings. Set aside the larger rings for frying.
Step 2: Preheat the Oil
- Pour oil into a heavy pot about 2 inches deep. Heat to 350°F (175°C). Keep an eye on the thermometer.
Step 3: Prepare Dry Coating
- Place 1/2 cup of flour in a shallow bowl. Lightly dredge each onion ring in flour. This helps the batter stick better.
Step 4: Make the Batter
- In a mixing bowl, whisk together the remaining 1 cup flour, cornstarch, baking powder, salt, pepper, paprika, and garlic powder.
- Slowly whisk in the cold sparkling water until the batter is smooth but not too thick. It should coat the back of a spoon but still flow easily.
Step 5: Dip and Fry
- Dip each floured onion ring into the batter, letting excess drip off. Carefully place into hot oil.
- Fry in small batches for 2–3 minutes per side until golden brown.
Step 6: Drain Properly
- Remove with tongs and place on a wire rack over paper towels. This keeps them crispy.
- Serve immediately while hot and crunchy.
