Ingredients

• 1 sweet or yellow onion, thinly sliced
• 1 1/2 cups buttermilk
• 1 1/2 cups all-purpose flour
• 1 1/2 teaspoons salt
• 1/2 teaspoon garlic powder
• 1/2 teaspoon black pepper
• 1/4 teaspoon cayenne pepper
• Vegetable oil, for frying

Instructions

1. Soak the onions
   Place the sliced onions in a bowl and cover with buttermilk. Let them soak for at least 30 minutes to tenderize and enhance flavor.
2. Prepare the coating
   In a shallow dish, combine flour, salt, garlic powder, black pepper, and cayenne pepper.
3. Dredge the onions
   Remove onions from the buttermilk, allowing excess liquid to drip off. Toss them in the flour mixture, coating evenly. Shake off any excess flour.
4. Heat the oil
   In a deep pan or fryer, heat vegetable oil to 350–375°F (175–190°C).
5. Fry in batches
   Carefully add onions to the hot oil in small batches. Fry for about 2 minutes, stirring gently to separate strands, until golden brown and crispy.
6. Drain and cool
   Remove with a slotted spoon and place on a wire rack or paper towel-lined plate to drain excess oil.

Serve warm for best texture.

FAQs

Why are my onion strings not crispy?

They are best served fresh, but you can reheat briefly in the oven to crisp them up.

What type of onion works best?
Sweet onions or yellow onions provide the best flavor and texture.

Can I bake instead of fry?
Baking is possible but won’t give the same crispy texture as frying.
