Step-by-Step Cooking Instructions
- Peel the onion and cut off the top while keeping the root intact so the onion holds together.
- Place the onion root side down and carefully slice it into equal sections without cutting through the base.
- Gently spread the onion layers apart using your fingers to create the blooming effect.
- In a bowl, combine flour, cornstarch, paprika, garlic powder, onion powder, salt, black pepper, and cayenne pepper. Mix well.
- In another bowl, whisk eggs, milk, and water until smooth and fully combined.
- Place the onion into the flour mixture and carefully coat all layers by sprinkling flour between the petals.
- Dip the floured onion into the egg mixture, ensuring liquid reaches deep inside the layers.
- Return the onion to the flour mixture and coat again thoroughly for a thick crispy layer.
- Set the coated onion on a plate and let it rest for ten minutes to help the coating stick better.
- Heat vegetable oil in a deep pot to medium heat until hot enough for frying.
- Carefully lower the onion into the oil with the root side up using a slotted spoon.
- Fry for four to five minutes until the outer layers turn golden brown.
- Flip the onion gently and fry for another four to five minutes until fully crispy.
- Remove the onion from oil and place on paper towels to drain excess oil.
- Let it rest briefly before serving to allow the onion to soften slightly inside.
Tips for Customizing the Recipe

• Use buttermilk instead of regular milk for richer batter texture.
• Add grated parmesan cheese to the flour mixture for savory depth.
• Serve with spicy mayo, garlic sauce, or honey mustard for variety.
• Bake the onion in a hot oven for a lighter version instead of frying.
