# What You'll Need:
→ Vegetables
01 - 2 large yellow onions
→ Batter
02 - 1 cup all-purpose flour
03 - ½ cup cornstarch
04 - 1 teaspoon baking powder
05 - 1 teaspoon smoked paprika
06 - 1 teaspoon garlic powder
07 - 1 teaspoon salt
08 - ½ teaspoon freshly ground black pepper
→ Wet Ingredients
09 - 1 cup cold sparkling water
10 - 2 large eggs
→ Coating
11 - 2 cups panko breadcrumbs
→ For Frying
12 - Vegetable oil for deep-frying (or air fryer spray)
# Method Steps:
01 - Peel onions and slice into ¾-inch thick rings. Separate each ring and set aside.
02 - In a large bowl, whisk together flour, cornstarch, baking powder, smoked paprika, garlic powder, salt, and black pepper.
03 - In a separate bowl, beat eggs with cold sparkling water until well combined.
04 - Add wet mixture to dry ingredients and whisk until smooth. If batter is too thick, add a little more sparkling water.
05 - Place panko breadcrumbs in a shallow dish for coating.
06 - Dip each onion ring into the batter, allow excess to drip off, then coat thoroughly with panko breadcrumbs.
07 - Heat vegetable oil to 350°F. Fry onion rings in batches for 2 to 3 minutes, turning occasionally, until golden and crispy. Drain on wire rack or paper towels.
08 - Preheat air fryer to 400°F. Arrange coated rings in a single layer; spray lightly with oil. Air-fry for 8 to 10 minutes, turning halfway, until crisp and golden.
09 - Stack fried onion rings into a tower on a platter and serve immediately with preferred dipping sauces.
